android setting Orientation locked the orientation

I need to play the embedded videos in webview in normal orientation(as the webview is, such as PORTRAIT or LANDSCAPE), and force into LANDSCAPE mode in fullscreen video. So I did as the following steps:

  1. change the Activity's config in manifest file to android:configChanges="keyboardHidden|orientation|screenSize".

  2. in the WebView's WebChromeClient class,

        @Override
    public void onShowCustomView(View view, CustomViewCallback callback) {
        LogUtil.d(TAG, "onShowCustomView");

        super.onShowCustomView(view, callback);
        mHandler.post(new Runnable(){

            @Override
            public void run()
            {
                Activity activity = getActivity();
                if(activity == null){
                    return;
                }
                activity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
            }

        });
    }

    @Override
    public void onHideCustomView()
    {
        super.onHideCustomView();
        mHandler.post(new Runnable(){

            @Override
            public void run()
            {
                Activity activity = getActivity();
                if(activity == null){
                    return;
                }
                activity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
                activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);                        
            }

        });
    }

;; After doing this, generally it works fine. But it has one fault: before playing the video in fullscreen, the activity/fragment can rotate according to the phone direction, but after i return from fullscreen(LANDSCAPE mode) to embedded(PORTRAIT mode), the activity/fragment never change its orientation. How can i handle this case? i just want to restore to the original state, not lock the orientation. Thanks

Add this line after you set the orientation

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);

It isn't a perfect solution, but works pretty handy in a pinch.

android:configChanges can be pretty dangerous, as it prevents the OS from doing its normal clean-up and recreation of activities.

Yes, you can control the screen orientation programmatically.
