The same program runs normally on the Android2.3 platform and reports an error on Android4.0.

Solution:

Comment out the statement for setting the video frame rate. // MMediaRecorder. setVideoFrameRate (mQuality. framerate );

After you remove setVideoFrameRate, you can set

MMediaRecorder. setVideoSize (videoWidth, videoHeight );
