How can I capture a video recording on Android?

Answer 1

Here is a simple video recording example using the MediaRecorder:

public class VideoCapture extends Activity implements OnClickListener, SurfaceHolder.Callback {
    MediaRecorder recorder;
    SurfaceHolder holder;
    boolean recording = false;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

        recorder = new MediaRecorder();
        initRecorder();
        setContentView(R.layout.main);

        SurfaceView cameraView = (SurfaceView) findViewById(R.id.CameraView);
        holder = cameraView.getHolder();
        holder.addCallback(this);
        holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

        cameraView.setClickable(true);
        cameraView.setOnClickListener(this);
    }

    private void initRecorder() {
        recorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
        recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);

        CamcorderProfile cpHigh = CamcorderProfile
                .get(CamcorderProfile.QUALITY_HIGH);
        recorder.setProfile(cpHigh);
        recorder.setOutputFile("/sdcard/videocapture_example.mp4");
        recorder.setMaxDuration(50000); // 50 seconds
        recorder.setMaxFileSize(5000000); // Approximately 5 megabytes
    }

    private void prepareRecorder() {
        recorder.setPreviewDisplay(holder.getSurface());

        try {
            recorder.prepare();
        } catch (IllegalStateException e) {
            e.printStackTrace();
            finish();
        } catch (IOException e) {
            e.printStackTrace();
            finish();
        }
    }

    public void onClick(View v) {
        if (recording) {
            recorder.stop();
            recording = false;

            // Let's initRecorder so we can record again
            initRecorder();
            prepareRecorder();
        } else {
            recording = true;
            recorder.start();
        }
    }

    public void surfaceCreated(SurfaceHolder holder) {
        prepareRecorder();
    }

    public void surfaceChanged(SurfaceHolder holder, int format, int width,
            int height) {
    }

    public void surfaceDestroyed(SurfaceHolder holder) {
        if (recording) {
            recorder.stop();
            recording = false;
        }
        recorder.release();
        finish();
    }
}

Also, do not forget to include these permissions in manifest:

<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
