Getting started with the Android WebView is fairly simple, whether you want load a remote URL or display pages stored in your app.
This tutorial walks you through creating a new Android Project, adding a WebView, loading a remote URL, and then loading a local HTML page.
Hello guys, so in my program I load the iPhone version of the news.google.com website into a WebView. When I try to click a link, nothing happens. The reason for this is because it is a java script that asks to open a new window. I have no idea how to implement this into my code.
- After having installed Mac OS Catalina 10.15.4, Xcode 11.4 and iOS13.4, my Flutter Application running on iOS (simulator and actual device iPhoneX) is very buggy! Before, I had a floatingActionButton working fine. And also Drawer (lef.
- This article will only provide code examples. However, in order to get your code working, you will absolutely need the correct applications and operating system. When developing iOS apps, there is less freedom with which tools you can use, compared to developing Android apps. This is what you need for iOS development: Mac OS computer (required).
- For example: APPABI:= armeabi armeabi-v7a x86 mipsThere are now a lot of good x86 devices in the wild, and this is a good opportunity to embrace this newplatform, and add x86 compatibility to your app if you haven’t done it yet.For Google apps, we are still trying to work with Google to add them back. If you decide to add theneeded package.
- I have a basic WebView loading and external webpage. External links will not load/do anything when clicked (within the webview is expected). Internal links load as expected. App transport security settings in plist set to 'Allow arbitrary loads'.
Note: This tutorial assumes you're a developer with limited or no experience with the Android development environment, but have some experience with Java. If you're already familiar with programming for Android, you may want to refer to to Building Web Apps in WebViewon the Android developer site instead.
Install Android Studio
This tutorial uses Android Studio, the new design-and-build IDE for Android. So you'll need start off by installing Android Studio, as described here:
Create a New Android Project
When the installation completes, Android Studio launches and displays the welcome screen.
To create a new project:
- Click New Project.
- On the next page, enter your application name, package name and target SDKs, and click Next.Note: If you only intend to support the Chromium WebView (rather than the old WebKit WebView) set Minimum required SDK to API 19: Android 4.4 (KitKat).
- On the next page, you're prompted to enter an application icon. (You can change the icon later, so don't worry if you don't have one right now.) When you're done, click Next.
- The next page lets you select the main Android activity for your application. For the purposes of this guide, select Blank Activity and click Next.Note: An Android Activity can be viewed as a screen of an app. In this case, the application's main activity will hold the web view. If you're planning to venture further into native Android development, you can find more information in the Android Activities API guide
- The next page lets you change the names for the default Activity and layout. Click Finish to accept the defaults and create the project.You now have a new Android project. Next, to add the WebView!
Note: After you have your project created,make sure you have the KitKat SDK installed.Go to Tools > Android > SDK Manager andmake sure you have Android 4.4 (API 19) installed.
Add the WebView
Android Studio will give you some boilerplate code to set up your application. Your project's structure should look something like this:
![Mac os app webview not working in release dates Mac os app webview not working in release dates](https://www.mathworks.com/help/rptgenext/ug/web_view_climatecontrolf688ff0f825b5958978626442388dc33.png)
A few of the more import folders are identified in the picture:
src/main/java
. Android Java source code.src/main/res
. Resources used by the native application.src/main/res/drawable-type
. Image resources used by the native application.src/main/res/layout
. XML layout files that define the structure of UI components.src/main/res/values
. Dimensions, strings, and other values that you might not want to hard-code in your application.src/main/AndroidManifest.xml
. The manifest file defines what's included in the application: activities, permissions, themes, and so on.
You need to add a WebView to the main activity's layout.
- Open the
activity_main.xml
file in thesrc/main/res/layout
directory if it is not already open. (You may also see afragment_main.xml
file. You can ignore this, as it's not required for this tutorial.)Select the Text tab at the bottom of the of theactivity_main.xml
editor to see the XML markup.This file defines the layout for your main activity, and the Preview panes show thea preview of the activity. The Blank Activity layout doesn't include any children. You'll need to add the WebView. - In the XML pane, remove the self-closing slash from the end of the
FrameLayout
element,and add the <WebView> element and a new closing tag, as shown: - To use the WebView you need to reference it in the Activity. Open the Java source file for the main activity,
MainActivity.java
in thesrc/main/java/<PackageName>
directory.Add the lines shown in bold.The existing code in theonCreate
method does the work of hooking up the Activity with the layout. The added lines create a new member variable,mWebView
, to refer to the web view.Remove the following code:The WebView is identified by the resource ID, which is specified by this line in the layout file:After adding the code, you'll see some warning messages in the margin of the editor.This is because you haven't imported the right classes for WebView. Luckily Android Studio canhelp you fill in the missing classes. The easiest way to do this is click and hover over an unknown class name and wait for a popup showing a 'quick fix' -- in this case,adding animport
statment for theWebView
class.Press Alt + Enter (Option + Enter on Mac) to accept the quick fix.WebView in hand you can move on to setting it up and and loading some juicy web content.
Enable JavaScript
WebViews don't allow JavaScript by default. To run a web application in the web view, you need to explicitly enable JavaScript by adding the following lines to the
onCreate
method:Load a Remote URL
If you're going to load data from a remote URL, your application needs permission to access the internet. This permission needs to be added in the application's manifest file.
- Open the
AndroidManifest.xml
file in thesrc/res
directory. Add the line in bold before the closing </manifest> tag. - The next step is to call the
loadUrl
method on the webview. Add the following line to the end of theonCreate
method.mWebView.loadUrl('http://beta.html5test.com/');
Now try running the project. If you don't have a device handy, you can create an emulator(AVD or Android Virtual Device) by going to Tools >Android > AVD Manager.
Note: To detect when a URL has started and finished loading,use
WebViewClient.onPageStarted
and WebViewClient.onPageFinished
.Handling Navigation
Now try changing the URL you're loading to
http://www.html5rocks.com/
and rerun your application.You'll notice something strange.If you run the application now with a site that has a redirect like
html5rocks.com
, your app ends up opening the site in a browser on the device, not in your WebView -- probably not what you expected. This is because of the way the WebView handles navigation events.Here's the sequence of events:
- The WebView tries to load the original URL from the remote server, and gets a redirect to a new URL.
- The WebView checks if the system can handle a view intent for the URL, if so the system handles the URL navigation, otherwise the WebView will navigate internally (i.e. the user has no browser installed on their device).
- The system picks the user's preferred application for handling an
http://
URL scheme -- that is, the user's default browser. If you have more than one browser installed,you may see a dialog at this point.
Mac Os App Webview Not Working In Released
If you're using a WebView inside an Android application to display some simple web content (for example, a help page), this may be exactly what you want to do. However, for more sophisticated applications, you may want to handle the navigation links yourself.
To handle navigation inside the WebView you need to override the WebView's
WebViewClient
, which handles various events generated by the WebView. You can use it to control how the WebView handles link clicks and page redirects.The default implementation of
WebViewClient
makes any URL open in the WebView:This is a good step forward, but what if you want to handle links for your site only, while opening other URLs in a browser?
To achieve this you need to extend the
WebViewClient
class and implement the shouldOverrideUrlLoading
method. This method is called whenever the WebView tries to navigate to a different URL. If it returns false, the WebView opens the URL itself. (The default implementation always returns false, which is why it works in the previous example.)Create a new class:
- Right-click the package name of your app and select New >Java Class
- Enter
MyAppWebViewClient
as the class name and click OK - In the new
MyAppWebViewClient.java
file, add the following code (changes shown in bold):The new code definesMyAppWebViewClient
as a subclass ofWebViewClient
and implements theshouldOverrideUrlLoading
method.TheshouldOverrideUrlLoading
method is called whenever the WebView is about to load a URL. This implementation checks for the String 'html5rocks.com' at the end of the host name of the URL. If the string exists, the method returns false, which tells the platform not to override the URL, but to load it in the WebView.For any other hostname, the method makes a request to the system to open the URL. It does this by creating a new Android Intent and using it to launch a new activity. Returning true at the end of the method prevents the URL from being loaded into the WebView. - To use your new custom WebViewClient, add the following lines to your
MainActivity
class:Now, a user can click any of the HTML5Rocks links and stay within the app, but links to external sites are opened in a browser.
Handling the Android Back Button
As you start playing around and navigating the awesome HTML5Rocks articles, hitting the back button on Android exits the application, even though you've explored a few pages of the site.
WebView has a method
canGoBack
which tells you if there is anything on the page stack that can be popped. All you need to do is detect a back button press and determine if you should step back through the WebView's history or allow the platform to determine the correct behaviour. Inside your MainActivity class, add the following method (in bold):Loading HTML files from the file system
A big advantage of using a WebView inside an installable application is that you can store assets inside the app. This lets your app work offline and improves load times, since the WebView can retrieve assets directly from the local file system.
To store files such as HTML, JavaScript, and CSS locally, put them in the assets directory. This is a reserved directory that Android uses for raw files that your app may need access to (i.e. files it knows it should minimise or compress).
In your project, create the
assets
directory in main (src/main/assets
).Generally it's good practice to keep your web files in a subdirectory, so create a www directory and put all your web content in it.
Note: Absolute paths do not work in the WebView when referring to other files, such as CSS and JavaScript. So make sure you make all references relative, instead of absolute (for example, instead of '/pages/somelink.html', use './pages/somelink.html').
Once you have everything in your assets directory, it's as simple as loading in the appropriate file:
You'll want to tweak the
shouldOverrideUrlLoading
method so it opens a browser for non-local pages:Now you are set to build a great WebView app!

Launch Timeline
Last updated August 11, 2020.
Latest update:
Aug 11, 2020: The target rollout population has been increased to 100% of users on Chrome Stable versions 80 and above, and the actual proportion of users with the new behavior enabled is now ramping up to 100% gradually. Users will receive the new behavior when they restart Chrome.
For the full Chrome release schedule, see here. For the SameSite-by-default and SameSite=None-requires-Secure launch timeline, see below:
- Early October, 2019: Experimental SameSite-by-default and SameSite=None-requires-Secure behavior launched to 50% of users on Chrome Canary and Dev (Chrome Canary and Dev versions 78+). Windows and Mac users on domain-joined devices and Chrome OS users on enterprise-registered devices will be excluded from the experiment. Chrome 78 Beta users will not receive the experimental behavior.
- October 31, 2019: Chrome 79 Beta released. Experiment extended to 50% of Chrome 79 Beta users, including domain-joined and enterprise-registered devices. Policies to manage the experimental behavior (see below) will be available on Chrome 79.
- Dec 10, 2019: Chrome 79 Stable released. Stable users on Chrome 79 will NOT receive the new SameSite behavior.
- Dec 19, 2019: Chrome 80 Beta released. Experimental behavior still enabled for 50% of Chrome 80 Beta users.
- February 4, 2020: Chrome 80 Stable released. The enablement of the SameSite-by-default and SameSite=None-requires-Secure enforcement will not be included in this initial Chrome 80 stable rollout. Please see the next item for more detailed information on the when SameSite enforcement will be enabled for Chrome 80 stable.
- February, 2020: Enforcement rollout for Chrome 80 Stable: The SameSite-by-default and SameSite=None-requires-Secure behaviors will begin rolling out to Chrome 80 Stable for an initial limited population starting the week of February 17, 2020, excluding the US President’s Day holiday on Monday. We will be closely monitoring and evaluating ecosystem impact from this initial limited phase through gradually increasing rollouts.
- March 2, 2020: The enablement of the SameSite enforcements has been increased beyond the initial population. However, it is still targeting an overall limited global population of users on Chrome 80 stable and newer. We continue to monitor metrics and ecosystem feedback via our tracking bug, and other support channels.
- March 9, 2020: The rollout population has been additionally increased, although it continues to target a fraction of the overall Chrome 80 stable population. We continue to monitor metrics and ecosystem feedback via our tracking bug, and other support channels.
- April 3, 2020: In light of the extraordinary global circumstances due to COVID-19, we’ve decided to temporarily roll back the enforcement of SameSite cookie labeling on Chrome 80 stable. We recognize the efforts of sites and individual developers who prepared for this change as part of our ongoing effort to improve privacy and security across the web. We appreciate the feedback from across the web ecosystem which has helped inform this decision. We will provide advance notice on here and the Chromium blog when we plan to resume the gradual rollout, which we’re now aiming for over the summer. Non-stable Chrome channels (e.g. Dev, Canary, and Beta) will continue with 50% enablement in Chrome 80 and later. More details on Chromium blog.
- May 28, 2020: We are planning to resume our SameSite cookie enforcement coinciding with the stable release of Chrome 84 on July 14, with enforcement enabled for Chrome 80+. (In other words, starting July 14, Chrome users on the older Stable releases (80, 81, and 83 -- for whom we recommend installing the latest update!) as well as the newly released Chrome 84 will gradually begin to receive the SameSite-by-default behavior.) Read more on our Chromium blog post.
- July 14, 2020: SameSite cookie enforcement has resumed, with a gradual rollout starting today (July 14) and ramping up over the next several weeks as we continue to monitor overall ecosystem readiness and engage with websites and services to ensure they are prepared for the SameSite labeling policy. The SameSite features are being enabled for Chrome Stable channel users on versions 80 and 81 (who should update Chrome!), 83, as well as the newly released 84.
- July 28, 2020: The rollout population has been increased to target a fraction of the overall Chrome 80+ stable population. We are monitoring metrics and ecosystem feedback on our tracking bug.
- Aug 11, 2020: The target rollout population has been increased to 100% of users on Chrome Stable versions 80 and above, and the actual proportion of users with the new behavior enabled is now ramping up to 100% gradually. Users will receive the new behavior when they restart Chrome.
The new SameSite behavior will not be enforced on Android WebView until later, though app developers are advised to declare the appropriate SameSite cookie settings for Android WebViews based on versions of Chrome that are compatible with the None value, both for cookies accessed via HTTP(S) headers and via Android WebView's CookieManager API. This does not apply to Chrome browser on Android, which will begin to enforce the new SameSite rules at the same time as the desktop versions of Chrome. The new SameSite behavior will not affect Chrome on iOS.

We’ve decided to temporarily roll back the enforcement of SameSite cookie labeling on Chrome 80 Stable and kSameSiteByDefaultCookies is once again set to base::FEATURE_DISABLED_BY_DEFAULT in Chromium master.
Feb 10, 2020
The Chrome policies LegacySameSiteCookieBehaviorEnabledForDomainList and LegacySameSiteCookieBehaviorEnabled which revert to the legacy cookie behavior for managed Chrome and ChromeOS instances will be available for at least 12 months after the release of Chrome 80 stable (Edit - May 29, 2020: until at least July 14, 2021). We will be monitoring feedback about these policies and will provide updates on their lifetime as appropriate.
Nov 21, 2019
Starting in Canary version 80.0.3975.0, the Lax+POST temporary mitigation can be disabled for testing purposes using the new flag --enable-features=SameSiteDefaultChecksMethodRigorously to allow testing of sites and services in the eventual end state of the feature where the mitigation has been removed. (Note that to enable multiple features, you must append the feature name to the comma-separated list of params for the --enable-features flag. Do not use multiple separate --enable-features flags.)
In addition, there is a bug affecting Chrome 78-79 which causes spurious SameSite warning messages to be emitted to the console when the user has cookies for other domains on the same site as a resource fetched in a cross-site context. We apologize for the confusion. This will be fixed in Chrome 80.
Clearing up some misconceptions and providing additional information about 'Lax + POST' (which is mentioned briefly on the chromestatus.com page):
- 'Lax + POST' does not result in the legacy behavior (i.e. the old behavior before the SameSite changes).
- “Lax + POST” is an intervention for Lax-by-default cookies (cookies that don’t specify a `SameSite` attribute) which allows these cookies to be sent on top-level cross-site POST requests if they are at most 2 minutes old. “Normal” Lax cookies are not sent on cross-site POST requests (or any other cross-site requests with a non-idempotent HTTP method such as PUT). This intervention was put in place to mitigate breakage to some POST-based login flows.
- If “Lax + POST” is affecting the cookies you are testing (i.e. if your cookie would have been excluded if not for the '+ POST' behavior due to its age), you will see a message in the DevTools console about the 2 minute threshold. This can be useful for debugging.
- For integration testing (if your cookie needs to be sent on cross-site POST requests), we recommend test cases with cookie age both below and above the threshold. For this, there is a command-line flag --enable-features=ShortLaxAllowUnsafeThreshold, which will lower the 2 minute threshold to 10 seconds, so that your test doesn’t have to wait for 2 whole minutes. This flag is available in Chrome 79.0.3945.16 and newer. (Note that if you are also using other --enable-features flags such as --enable-features=SameSiteByDefaultCookies,CookiesWithoutSameSiteMustBeSecure, you must append the feature name to the comma-separated list rather than use multiple --enable-features flags.)
- Note that the 2-minute window for 'Lax+POST' is a temporary intervention and will be removed at some point in the future (some time after the Stable launch of Chrome 80), at which point cookies involved in these flows will require `SameSite=None` and `Secure` even if under 2 minutes old.
Mac Os App Webview Not Working In Release Endorphins
In response to feedback from users and enterprise customers, we are deferring the experimental Beta launch of the 'SameSite=Lax by Default' and 'SameSite=None requires Secure' features from Chrome 78 Beta to Chrome 79 Beta. Users of Chrome 78 Beta will not experience any change or disruption in cookie behavior.
When the experiment is launched to Chrome 79 Beta users, domain-joined or enterprise-registered machines will be included in the experiment. Instead of excluding them from the experiment entirely, policies will be made available in Chrome 79 to manage the experimental behavior. This will provide extra time for administrators to configure and test the policies in advance of the Stable launch in Chrome 80.
One policy will allow administrators to specify a list of domains on which cookies should be handled according to the legacy behavior (LegacySameSiteCookieBehaviorEnabledForDomainList), and a second policy will provide the option to set the global default to legacy SameSite behavior for all cookies (LegacySameSiteCookieBehaviorEnabled). More details about these policies will follow in future enterprise release notes before the Chrome 79 release.
These features will still become the default behavior on Stable starting in Chrome 80.
Sept 30, 2019
Note (Jan 30, 2020): Check out our more detailed tips for testing and debugging.
To test whether your sites may be affected by the SameSite changes:
- Go to chrome://flags and enable #same-site-by-default-cookies and #cookies-without-same-site-must-be-secure. Restart the browser for the changes to take effect.
- Test your sites, with a focus on anything involving federated login flows, multiple domains, or cross-site embedded content. Note that, because of the 2 minute time threshold for the 'Lax+POST' intervention, for any flows involving POST requests, you may want to test with and without a long (> 2 minute) delay.
- If your site stops working:
- Try turning off #cookies-without-same-site-must-be-secure. If this fixes the issue, you need to set `Secure` on any `SameSite=None` cookies your site may be relying upon. (This may require upgrading HTTP sites to HTTPS.)
- Try turning off both flags. If this fixes the issue, you need to identify the cookies being accessed in a cross-site context and apply the attributes `SameSite=None` and `Secure` to them. See 'SameSite cookies explained' for more information. If you are not the developer of the site, please reach out to the developer and/or vendor who authored the site.
- For flows involving POST requests, if a short delay (< 2 minutes) works but a long delay (> 2 minutes) does not work, you will also need to add `SameSite=None` and `Secure` to the relevant cookies if the operation in question may take longer than 2 minutes. Note that the 2-minute window for 'Lax+POST' is a temporary intervention and will be removed at some point in the future (some time after the Stable launch of Chrome 80), at which point cookies involved in these flows will require `SameSite=None` and `Secure` even if under 2 minutes.
If you are an IT administrator managing a Chrome deployment for your organization, policies will temporarily be made available to maintain Chrome's existing behavior for your users. This is to give enterprises extra time to roll out and test changes. You have two options:
- (Recommended) Apply the LegacySameSiteCookieBehaviorEnabledForDomainList policy to the specific domains on which cookies require legacy behavior.
- (Less recommended due to security and privacy implications) Apply the LegacySameSiteCookieBehaviorEnabled policy to revert all cookies to legacy behavior.
These policies will be made available starting in Chrome 80. Chrome 79. (See Oct 2, 2019 update.)
Sept 26, 2019
Starting in Chrome 80, cookies that do not specify a SameSite attribute will be treated as if they were SameSite=Lax with the additional behavior that they will still be included in POST requests to ease the transition for existing sites. Cookies that still need to be delivered in a cross-site context can explicitly request SameSite=None, and must also be marked Secure and delivered over HTTPS. We will provide policies if you need to configure Chrome Browser to temporarily revert to legacy SameSite behavior.
This section is obsolete: See Oct 2, 2019 update.Mac Os App Webview Not Working In Release Dates
Mac Os App Webview Not Working In Release Date
The new SameSite rules will become the default behavior on Stable in Chrome 80, but the changes will be limited to pre-Stable versions of Chrome until then.
Policies to manage this behavior will be made available when it becomes the default behavior for Chrome 80. One policy will allow administrators to specify a list of domains on which cookies should be handled according to the legacy behavior, and second policy will provide the option to set the global default to legacy SameSite behavior for all cookies. More details about these policies will follow in future enterprise release notes before the Chrome 80 release.
