The process of reproducing the behavior:

          Message App --> New Message --> Attach --> Capture Video -->click the Shutter button to start recording video --> click the shutter button to stop recording video --> flashlight is not gray state

The solutions:     

private Runnable mVideoSavedRunnable = new Runnable(){     public void run(){         ...         setEnableRecordingUI(true);         ...     }}public void setEnableRecordingUI(boolean enable){    ...    mFlashIndicator.setEnable(enable);    ...}

As the code ,when Saving the video ,the setEnableRecordingUI() has been invoked.So we should add a judge condition to judge whether the activity is started by others or not. If others(like:Message App) start the video activity,we shouldn't enable the RecordingUI .

Thus ,we can do like these:

private Runnable mVideoSavedRunnable = new Runnable(){     public void run(){         ...         if (!mIsVideoCaptureIntent){             setEnableRecordingUI(true);         }            ...     }}
