androidx.webkit

Kotlin |Java

The androidx.webkit library is a static library you can add to your Android application in order to use android.webkit APIs that are not available for older platform versions.

Requirements

The minimum sdk version to use this library is 14.

How to declare the dependencies to use the library

Inside your app's build.gradle file, include this line in dependencies:

dependencies {
    ...
    implementation 'androidx.webkit:webkit:1.1.0'
}

Migrating to androidx.webkit

For static methods:

Old code:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O_MR1) {
    WebView.startSafeBrowsing(appContext, callback);
}

New code:

if (WebViewFeature.isFeatureSupported(WebViewFeature.START_SAFE_BROWSING)) {
    WebViewCompat.startSafeBrowsing(appContext, callback);
}

Or, if you are using a non-static method:

Old code:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    myWebView.postVisualStateCallback(requestId, callback);
}

New code:

if (WebViewFeature.isFeatureSupported(WebViewFeature.VISUAL_STATE_CALLBACK)) {
    WebViewCompat.postVisualStateCallback(myWebView, requestId, callback);
}
