myVideoRecorder.setAudioSource (MediaRecorder.AudioSource.CAMCORDER);
Directly with the default input device it? You did not see the audio path open to print, the print driver to see what's wrong yet? You can also try mms which has a recording function is not normal, you can go to troubleshoot the hardware and driver area.

Big Brother did not solve the problem, I have encountered

Rub a lot of people that encounter this problem. . The emergence of this problem on my 2.1 to 4.0 on the test developed

I have this problem, the development environment 2.2, 4.0 debugging real machine, is the problem, how to solve Oh, please, Daniel
Reply:
The myVideoRecorder.start () and myVideoRecorder.prepare () in the same try catch, I can solve

Question should be here: threadid = 1: thread exiting with uncaught exception (group = 0x40a8a1f8)
In mMediaRecorder.start () before adding:
mMediaRecorder.setOnInfoListener (this);
mMediaRecorder.setOnErrorListener (this);
Activity is mainly to achieve OnInfoListener and OnErrorListener Interface

Seemingly must first turn off the camera camera.stopPreview ();
camera.release ();
camera = null;
I am very reluctant to turn off the camera, I took note of the code, the results appeared landlord. Uncomment enough.

My question is the same, but, when I tested some machine line, not some machine, are MediaRecorder.start (); being given this place, seeking solutions ah ~
