I am developing an app that is supposed to record videos using the front facing camera. It is working now using the back camera. When I tried to change the cameraID to select the profile of the front facing camera as mentioned in
actually nothing happens and still the back camera is used.
public class MainActivity extends Activity implements View.OnClickListener, SurfaceHolder.Callback {
public static MediaRecorder recorder;
public static SurfaceHolder holder;
public static SurfaceView cameraView;
boolean recording = false;
public static final int RequestPermissionCode = 2;
@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);
if(checkPermission()) {
initRecorder();
setContentView(R.layout.activity_main);
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);
} else {
requestPermission();
initRecorder();
setContentView(R.layout.activity_main);
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 int getCamID() {
int cameraCount = 0;
Camera cam = null;
Camera.CameraInfo cameraInfo = new Camera.CameraInfo();
cameraCount = Camera.getNumberOfCameras();
for (int camIdx = 0; camIdx<cameraCount; camIdx++) {
Camera.getCameraInfo(camIdx, cameraInfo);
if (cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
return camIdx;
}
}
return 0;
}
private void initRecorder() {
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
int camID = getCamID();
CamcorderProfile cpHigh = CamcorderProfile
.get(camID,CamcorderProfile.QUALITY_LOW);
recorder.setProfile(cpHigh);
//get the time stamp
String timestamp = new Timestamp(System.currentTimeMillis()).toString();
//remove the seconds part
timestamp = timestamp.substring(0, timestamp.length()-6).replaceAll(":","");
//append file name to the time stamp
String filestamp = timestamp;
recorder.setOutputFile(Environment.getExternalStorageDirectory().getAbsolutePath() + "/" +
filestamp +".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;
recorder.release();
// Let's initRecorder so we can record again
} else {
initRecorder();
prepareRecorder();
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();
}
private void requestPermission() {
ActivityCompat.requestPermissions(MainActivity.this, new
String[]{WRITE_EXTERNAL_STORAGE, RECORD_AUDIO,CAMERA}, RequestPermissionCode);
}
public boolean checkPermission() {
int result = ContextCompat.checkSelfPermission(getApplicationContext(),
WRITE_EXTERNAL_STORAGE);
int result1 = ContextCompat.checkSelfPermission(getApplicationContext(),
RECORD_AUDIO);
int result2 = ContextCompat.checkSelfPermission(getApplicationContext(),
CAMERA);
return result == PackageManager.PERMISSION_GRANTED &&
result1 == PackageManager.PERMISSION_GRANTED &&
result2 == PackageManager.PERMISSION_GRANTED;
