Cannot handle camera in two fragments having video recorder and Camera capture

I am making Instagram like app in which there are different screens for capturing image and recording image. My problem is that when I run my app with both fragment then my app crashes leaving error :
FATAL EXCEPTION: main
java.lang.RuntimeException: Fail to connect to camera service
at android.hardware.Camera.native_setup(Native Method)
at android.hardware.Camera.<init>(Camera.java:428)
at android.hardware.Camera.open(Camera.java:389)
at textileapp.ebizz.com.myapplication.VideoFragment.onCreateView(VideoFragment.java:55)
But when I ran my app with only one fragment either camera screen ot video recorder screen, then it works fine. But with both fragment together app crashes. Ca any one help with this.

Tap and hold to record video like Vine

I want to make an app that record video, it seems like vine, hold to record, release it stop, hold to record and keep that to the end.

You can do achieve this functionality by setting OnLongClickListener() and OnTouchListener() on your record button. Like this:
recordBtn.setOnLongClickListener(recordBtnLCListener);
recordBtn.setOnTouchListener(recordBtnTouchListener);
then :
#Override
public boolean onLongClick(View v) {
ivCancel.setVisibility(View.GONE);
ivDone.setVisibility(View.GONE);
isActionDown = true;
try {
if (isActionDown) {
initRecorder();
if (isActionDown)
prepareRecorder();
}
if (isPrepared && isActionDown) {
mMediaRecorder.start();
isRecording = true;
}
} catch (Exception e) {
e.printStackTrace();
Log.e("onLongPress Error ", e.toString());
}
return true;
}
and :
#Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_UP:
isActionDown = false;
try {
if (isRecording) {
if (mMediaRecorder != null) {
mMediaRecorder.stop();
}
isRecording = false;
}
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
break;
}
return false;
}
So, in this way you can record the parts of video.Means each time you LongPress your record button, the recording starts. And time you release the button, the recording stops and here you have to save this part of video in any temporary folder.
Once you done taking all parts of videos as many as you want, then you have to combine all that parts of videos to make a single video.
Here, is the code to merge all that video parts saved in temperory folder:
public void mergeVideos() {
try {
List<Movie> inMovies = new ArrayList<>();
for (int i = 0; i < videosPathList.size(); i++) {
String filePath = videosPathList.get(i);
try {
Movie movie = MovieCreator.build(filePath);
if (movie != null)
inMovies.add(movie);
} catch (Exception e) {
e.printStackTrace();
}
}
List<Track> videoTracks = new LinkedList<Track>();
List<Track> audioTracks = new LinkedList<Track>();
for (Movie m : inMovies) {
for (Track t : m.getTracks()) {
try {
if (t.getHandler().equals("soun")) {
audioTracks.add(t);
}
if (t.getHandler().equals("vide")) {
videoTracks.add(t);
}
} catch (Exception e) {
}
}
}
Movie result = new Movie();
if (audioTracks.size() > 0) {
result.addTrack(new AppendTrack(audioTracks
.toArray(new Track[audioTracks.size()])));
}
if (videoTracks.size() > 0) {
result.addTrack(new AppendTrack(videoTracks
.toArray(new Track[videoTracks.size()])));
}
BasicContainer out = (BasicContainer) new DefaultMp4Builder().build(result);
File f = null;
String finalVideoPath;
try {
f = setUpVideoFile(Environment
.getExternalStorageDirectory()+"/MyApp/videos/");
finalVideoPath = f.getAbsolutePath();
} catch (IOException e) {
e.printStackTrace();
f = null;
finalVideoPath = null;
}
WritableByteChannel fc = new RandomAccessFile(finalVideoPath, "rw").getChannel();
out.writeContainer(fc);
fc.close();
deleteFilesDir(); //In this method you have to delete all parts of video stored in temporary folder.
} catch (Exception e) {
e.printStackTrace();
progressDialog.dismiss();
finish();
}
}
File setUpVideoFile(String directory) throws IOException {
File videoFile = null;
if (Environment.MEDIA_MOUNTED.equals(Environment
.getExternalStorageState())) {
File storageDir = new File(directory);
if (storageDir != null) {
if (!storageDir.mkdirs()) {
if (!storageDir.exists()) {
Log.d("CameraSample", "failed to create directory");
return null;
}
}
}
videoFile = File.createTempFile("video_"
+ System.currentTimeMillis() + "_",
.mp4, storageDir);
}
return videoFile;
}
You can call mergeVideos() method after stopping mediaRecorder.
Hope this code helps you. :)
For merging the videos you have to use the isoparser library. So you have to add following dependendy in your gradle file :
compile 'com.googlecode.mp4parser:isoparser:1.0.5.4'

This is my code.

Android Camera surface-view camera recreated when i press back button on archos tablet on jellybean

In my code i have camera preview and video recording on button click so my code works well for recording and preview.
but when i press back button then surfaceview create and surface view change method get called after that surfaceview destroy method called so i have to press back button again and at this time it directly call surface destroy ( second time surface create and surface change is not called)

Based on debugging/discussion on chat:
the first time back is being hit, the existing Camera activity gets destroyed and another one is created. Used the following to follow the changes in the back stack:
adb shell dumpsys activity | grep -i run
No new task is required, so this is useless:
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
Apparently, using i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP) helps!
I'm not sure why exactly this is helping though. (Especially, because IIUC, with *CLEAR_TOP, the existing instance of the activity on the stack would be used (with onNewIntent), but here (based on the output from dumpsys, a new activity gets created :|). But it works on archos.

Custom Video Recording Screen

I am trying to implement an application which when starts starts video recording automatically with my custom video recording screen with my own button to stop the recording and with other buttons. What I have done is designed the layout with buttons till now but how to add video recording screen in the background..Please help.!

surfaceView = (SurfaceView) findViewById(R.id.preview);
surfaceHolder = surfaceView.getHolder();
surfaceHolder.addCallback(this);
btnStop = (Button) findViewById(R.id.btn_stop);
surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
isSDPresent = android.os.Environment.getExternalStorageState().equals(
android.os.Environment.MEDIA_MOUNTED);
}
public static float megabytesAvailable(File f) {
StatFs stat = new StatFs(f.getPath());
long bytesAvailable = (long) stat.getBlockSize()

});
}

recorder.setPreviewDisplay(surfaceHolder.getSurface());
if (usecamera) {

recorder.setCamera(camera);
}
recorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
recorder.setProfile(camcorderProfile);
if (camcorderProfile.fileFormat == MediaRecorder.OutputFormat.MPEG_4) {

You can create your own Video Recording Screen
Try like this, First Create a Custom Recorder using SurfaceView
public class VideoCapture extends SurfaceView implements SurfaceHolder.Callback {
private MediaRecorder recorder;
private SurfaceHolder holder;
public Context context;
private Camera camera;
public static String videoPath = Environment.getExternalStorageDirectory()
.getPath() +"/YOUR_VIDEO.mp4";
public VideoCapture(Context context) {
super(context);
this.context = context;
init();
}
public VideoCapture(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public VideoCapture(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
#SuppressLint("NewApi")
public void init() {
try {
recorder = new MediaRecorder();
holder = getHolder();
holder.addCallback(this);
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
camera = getCameraInstance();
if(android.os.Build.VERSION.SDK_INT > 7)
camera.setDisplayOrientation(90);
camera.unlock();
recorder.setCamera(camera);
recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
recorder.setOutputFile(videoPath);
} catch (Exception e) {
e.printStackTrace();
}
}
public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) {
}
public void surfaceCreated(SurfaceHolder mHolder) {
try {
recorder.setPreviewDisplay(mHolder.getSurface());
recorder.prepare();
recorder.start();
} catch (Exception e) {
e.printStackTrace();
}
}
public void stopCapturingVideo() {
try {
recorder.stop();
camera.lock();
} catch (Exception e) {
e.printStackTrace();
}
}
#TargetApi(5)
public void surfaceDestroyed(SurfaceHolder arg0) {
if (recorder != null) {
stopCapturingVideo();
recorder.release();
camera.lock();
camera.release();
recorder = null;
}
}
private Camera getCameraInstance() {
Camera c = null;
try {
c = Camera.open(); // attempt to get a Camera instance
} catch (Exception e) {
// Camera is not available (in use or does not exist)
}
return c;
}
}
And you can use it inside your Layout for Activity Class
<your_package.VideoCapture
android:id="#+id/videoView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#00000000" />
EDITED:-
public class CaptureVideo extends Activity {
private VideoCapture videoCapture;
private Button stop;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.video_capture);
videoCapture = (VideoCapture) findViewById(R.id.videoView);
stop= (Button) findViewById(R.id.stop);
stop.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
videoCapture.stopCapturingVideo();
setResult(Activity.RESULT_OK);
finish();
}
});
}
}
Hope this will help you

This way is using fragments:
public class CaptureVideo extends Fragment implements OnClickListener, SurfaceHolder.Callback{
private Button btnStartRec;
