Added in 1.7.0

Kotlin |Java

public final class DropDataContentProvider extends ContentProvider

java.lang.Object
↳	android.content.ContentProvider
	↳	androidx.webkit.DropDataContentProvider

WebView provides partial support for Android Drag and Drop allowing images, text and links to be dragged out of a WebView.

The content provider is required to make the images drag work, to enable, you should add this class to your manifest, for example:

 <provider
            android:authorities="<your-package>.DropDataProvider"
            android:name="androidx.webkit.DropDataContentProvider"
            android:exported="false"
            android:grantUriPermissions="true"/>
