    NPM version

    Cordova plugin that checks which version of Android System Webview is installed.

    This plugin helps you to prevent the white screen of death for your Cordova/Ionic applications. Different versions of Android come with a different version of Android System WebView installed. Certain JS features work only in newer webview versions, so when a user tries to start a Cordova/Ionic application with an older webview implementation, the JS parser throws an error which will lead to an empty white screen. This plugin can be used to check the available webview version before parsing your main application bundle and show a meaningful error message to the user.

    • use ES5 code only
    • put your code for this plugin directly
      • into the index.html
      • into a separate js file what is included before the application code in index.html
    • avoid the list of known issues in the quirks section
    • you need to wait for the deviceready signal to start using the API

    This plugin is used to detect the version of the WebView before launching your app, it should not be used in your application code, but directly added to index.html via a script tag (inline or not) to render an error state if the required Webview version is not present.

    Usage of language features above ES5

    Do not use anything else than ES5 to write your handler logic for this plugin and do not bundle it into your main application. The reason for this is that the older versions of webview do not support most of the ES6+ features and can only interpret ES5 code.

    Known issues and quirks

    Do not pass the any console function as a parameter in a promise handler (like .then(console.log)). This will cause an Uncaught TypeError: Illegal invocation error in older versions of the Android System WebView.


    The Android System WebView was first shipped in Android 4.4 (KitKat) and based on Chrome for Android 30. Every phone which comes with Google Play installed has it From Android 4.4. In Android 5.0 (Lollipop) the WebView has been decoupled from the OS and become updatable through the Play Store. Above Android 7.0 the Android System WebView will be disabled and won't be updated as long as Chrome is installed and enabled.

    Pre-installed Versions

    • Android 6.0 (Marshmallow) - Android System WebView 44.0.2403.117
    • Android 7.0 (Nougat) - disabled by default as Chrome 51+ is used for rendering

      .catch(function(error) { console.error(error); });

    Note: Technically all Android phone has the Android System WebView installed but when it's disabled it will default to the version shipped with the phone. So you should determine a minimum required version and use plugins.webViewChecker.getCurrentWebViewPackageInfo() function to check if the installed version is higher or not.
