Record, save and play a video in Android

Question

I am trying to make an app that records a video using the camera app, and then saves that video on SD card so I can play it. I have some code but I'm lost on how to continue as I'm a beginner in Android.

My Activity:

public class Camcorder extends Activity {

     private CamcorderView camcorderView; 
     private boolean recording = false; 

     /** Called when the activity is first created. */ 
     @Override 
     public void onCreate(Bundle savedInstanceState) { 
          super.onCreate(savedInstanceState);
          //irrelevant code

          camcorderView = (CamcorderView) findViewById(R.id.camcorder_preview); 
     } 

     @Override 
     public boolean onKeyDown(int keyCode, KeyEvent event) 
     { 
         if (keyCode == KeyEvent.KEYCODE_DPAD_CENTER) 
         { 
          if (recording) { 
                camcorderView.stopRecording();
                finish(); 
            } else { 
                recording = true; 
                camcorderView.startRecording(); 
            } 
             return true; 
         } 
         return super.onKeyDown(keyCode, event); 
     }       
}

CamcorderView class:

public class CamcorderView extends SurfaceView implements
    SurfaceHolder.Callback {

MediaRecorder recorder;
SurfaceHolder holder;
String outputFile = "/sdcard/default.mp4";

public CamcorderView(Context context, AttributeSet attrs) {
    super(context, attrs);

    holder = getHolder();
    holder.addCallback(this);
    holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

    recorder = new MediaRecorder();
    recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
    recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
    recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
    recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
    // recorder.setVideoSize(480, 320);
    // recorder.setVideoFrameRate(15);
    // recorder.setMaxDuration(10000);
}

public void surfaceCreated(SurfaceHolder holder) {
    recorder.setOutputFile(outputFile);
    recorder.setPreviewDisplay(holder.getSurface());
    if (recorder != null) {
        try {
            recorder.prepare();
        } catch (IllegalStateException e) {
            Log.e("IllegalStateException", e.toString());
        } catch (IOException e) {
            Log.e("IOException", e.toString());
        }
    }
}

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

public void surfaceDestroyed(SurfaceHolder holder) {
}

public void setOutputFile(String filename)
{
    outputFile = filename;
    recorder.setOutputFile(filename);
}

public void startRecording()
{
    recorder.start();
}

public void stopRecording()
{
    recorder.stop();
    recorder.release();
}
}

Well it's very simple to record videos in android by using this simple code

First on a button click simple start an Intent

Intent takeVideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
if (takeVideoIntent.resolveActivity(getPackageManager()) != null) {
    startActivityForResult(takeVideoIntent, CAMERA_REQUEST_CODE_VEDIO);
}

then in onActivityResult method

Uri videoUri = data.getData();
path = Utils.getRealPathFromURI(videoUri, this);
manageVideo(path); //Do whatever you want with your video

and finally add permissions to the manifest

<uses-feature
    android:name="android.hardware.camera"
    android:required="true" />

Hope it help others who are looking for help :)

Thanks
