I want to turn off the sound of pressing the record button. When you press the button, the sound "beep" occurs. How to turn off this sound?
If in the class CameraService.java remove mMediaRecorder.setAudioSource (MediaRecorder.AudioSource.MIC) then an error occurs!

After selecting the front camera, recording is performed by the Back camera:

mMediaRecorder.setProfile(CamcorderProfile.get(findFrontFacingCamera(),CamcorderProfile.QUALITY_LOW));

private int findFrontFacingCamera() {
        int cameraId = -1;
        // Search for the front facing camera
        int numberOfCameras = Camera.getNumberOfCameras();
        for (int i = 0; i < numberOfCameras; i++) {
            Camera.CameraInfo info = new Camera.CameraInfo();
            Camera.getCameraInfo(i, info);
            if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
                Log.d(TAG, "Camera found");
                cameraId = i;
                break;
            }
        }
        return cameraId;
    }

What am I doing wrong?Help me please

In MainActivityJava
lines 38,39,80

Stackoverflow Post here

I just change 2 Lines of the project to switch to the front camera but it failed. Under the path it generate a MP4 file, but my cell phone failed to open it. (real device debugging)

Thanks for the code, but I am wondering what if the service needs to be a remote service witch runs in another process? Can camera open and running works in this remote service?

See Details

Can I ask for help?

• I want to combine my analyzing code with your ServiceCamera code.
• I write my analyzing code in mCamera.setPreviewCallback -> @override onPreviewFrame() function.
• But the @override onPreviewFrame() function seem never work.

My Current Project but without the Service
