Video does not play in full screen

Question

I get NPE when trying to play embedded video in webview in FULLSCREEN. It works great with 3.0 cells, but not with ICS 4.0+. Any idea how this can be solved?

java.lang.NullPointerException at android.webkit.PluginFullScreenHolder.show(PluginFullScreenHolder.java:85) at android.webkit.WebView$PrivateHandler.handleMessage(WebView.java:8849) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:4424) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:511) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:784) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:551) at dalvik.system.NativeStart.main(Native Method) 

Any suggestion would be truly appreciated. Thanks

Answer 1

Try adding WebChromeClient to your WebView:

 webView.setWebChromeClient(new WebChromeClient()); 

This should stop the crash (I think it looks like we were experiencing), but I don’t think it will make the video play in full screen mode.

For this, I think you will need to do something like this: Android ICS 4.0 Placing Flash WebView in pop-up screens of hideAll Method? I'm still trying to find out.

The problem is a bug in the Android OS. To solve this problem you need work.
I ran into the same problem. The following work worked for me.
Hope this helps some people:
Create a FullscreenableChromeClient and add this line:

 WebView.setWebChromeClient( new FullscreenableChromeClient(this)); 

  public class FullscreenableChromeClient extends WebChromeClient { protected Activity mActivity = null; private View mCustomView; private WebChromeClient.CustomViewCallback mCustomViewCallback; private int mOriginalOrientation; private FrameLayout mContentView; private FrameLayout mFullscreenContainer; private static final FrameLayout.LayoutParams COVER_SCREEN_PARAMS = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT); public FullscreenableChromeClient(Activity activity) { this.mActivity = activity; } @Override public void onShowCustomView(View view, int requestedOrientation, WebChromeClient.CustomViewCallback callback) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) { if (mCustomView != null) { callback.onCustomViewHidden(); return; } mOriginalOrientation = mActivity.getRequestedOrientation(); FrameLayout decor = (FrameLayout) mActivity.getWindow().getDecorView(); mFullscreenContainer = new FullscreenHolder(mActivity); mFullscreenContainer.addView(view, COVER_SCREEN_PARAMS); decor.addView(mFullscreenContainer, COVER_SCREEN_PARAMS); mCustomView = view; setFullscreen(true); mCustomViewCallback = callback; mActivity.setRequestedOrientation(requestedOrientation); } super.onShowCustomView(view, requestedOrientation, callback); } @Override public void onHideCustomView() { if (mCustomView == null) { return; } setFullscreen(false); FrameLayout decor = (FrameLayout) mActivity.getWindow().getDecorView(); decor.removeView(mFullscreenContainer); mFullscreenContainer = null; mCustomView = null; mCustomViewCallback.onCustomViewHidden(); mActivity.setRequestedOrientation(mOriginalOrientation); } private void setFullscreen(boolean enabled) { Window win = mActivity.getWindow(); WindowManager.LayoutParams winParams = win.getAttributes(); final int bits = WindowManager.LayoutParams.FLAG_FULLSCREEN; if (enabled) { winParams.flags |= bits; } else { winParams.flags &= ~bits; if (mCustomView != null) { mCustomView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE); } else { mContentView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE); } } win.setAttributes(winParams); } private static class FullscreenHolder extends FrameLayout { public FullscreenHolder(Context ctx) { super(ctx); setBackgroundColor(ctx.getResources().getColor(android.R.color.black)); } @Override public boolean onTouchEvent(MotionEvent evt) { return true; } } }
