WanghongLin, thank you very much. But what to do for devices which have higher API (API 17 +) ? These devices use com.android.webview.chromium, and the reflection returns ClassNotFound exception for "android.webkit.WebViewClassic" and "android.webkit.HTML5VideoView". . I'm looking forward for your reply.
