I want to create a custom camera app in android. I have one activity that uses two fragments. One fragment is for camera and another is for show picture or video that was taken. When activity starts, It loads camera fragment. In preview of camera there is a button that uses for record video. In long press on button recording starts and after end of long press video recording stops and file is send to the fragment that show the video. In other word, at the end of long press on button I replace the camera fragment with a new fragment that show the result. In onPause of camera fragment I stopped the cameradevice but after some back and forth between fragments I can't use the camera at all. After some back and forth no camera application doesn't work in my phone and I have to restart my phone.
these are some codes of my camera fragment
#OnLongClick(R.id.capture)
public boolean captureLongPressed() {
startRecord();
mMediaRecorder.start();
return true;
}
#OnTouch(R.id.capture)
public boolean captureOnTouch(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_UP) {
if (isRecordButtonLongPressed) {
mIsRecording = false;
try {
mMediaRecorder.stop();
mMediaRecorder.reset();
} catch (RuntimeException ex) {
}
if (listener != null)
listener.onVideoRecorded(mVideoFileName);
return true;
}
}
return false;
}

try {
setupMediaRecorder();

Please help me …
Thanks in advance
I have do like it will capture image in background without any preview screen using Camera2 API in background service.
Visit https://codepalyers.blogspot.com/2020/12/capture-image-in-background-without.html
If you wish to use rear camera use
private final String frontCamera = "1";
private final String backCamera = "0";
as already define in code.
I am not able to get a constant framerate with the camera2 API using MediaRecorder on the Galaxy S9 front camera.
Essentially I am using the example Project from https://github.com/googlesamples/android-Camera2Video but stripped it down to find the error. I removed the mTextureView and use only the mediaRecorder surface.
Here are the relevant code snippets:

getRange() returns a Range of [30,30]. So it should record at 30fps. If I move the camera to some darker areas the frame rate suddenly drops. If locking the AE while moving to a light area the framerate is stable, even in dark areas.
So it seems to have something to do with AE but can not figure out what. Any help?
I am using the Camera2 api to show a preview form the camera. I also want to implement a ImageReader to process the images. I have a Start preview function. When I call it the preview is just black. If I remove "mimageReader.getSurface()" from Arrays.asList() I am able to see the camera preview. How can I have a camera preview show up and also use ImageReader?
private void startPreview()
{
List<Surface> outputSurfaces = new ArrayList<>();
List surfaces = new ArrayList<>();
SurfaceTexture surfaceTexture = textureView.getSurfaceTexture();
surfaceTexture.setDefaultBufferSize(mPreviewSize.getWidth(), mPreviewSize.getHeight());
Surface previewSurface = new Surface(surfaceTexture);
try {
mCaptureRequestBuilder = _cameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_PREVIEW);
mCaptureRequestBuilder.addTarget(previewSurface);
_cameraDevice.createCaptureSession(Arrays.asList(previewSurface,mimageReader.getSurface()),
new CameraCaptureSession.StateCallback() {
#Override
public void onConfigured(CameraCaptureSession session) {
Log.d("", "onConfigured: startPreview");
try {
session.setRepeatingRequest( mCaptureRequestBuilder.build(),null,mthreadhandler);
} catch (CameraAccessException e) {
e.printStackTrace();
}
}
#Override
public void onConfigureFailed(CameraCaptureSession session) {
Log.d("", "onConfigureFailed: startPreview");
}
}, null);
} catch (CameraAccessException e) {
e.printStackTrace();
}
}
You have to create a new instance of ImageReader, set its onImageAvailableListener(you can process the preview frames here) and add it to PreviewRequestBuilder. For example:
mImageReader = ImageReader.newInstance(
mPreviewSize.getWidth(), mPreviewSize.getHeight(), ImageFormat.YUV_420_888, 2);
mImageReader.setOnImageAvailableListener(mOnGetPreviewListener, mBackgroundHandler);
mPreviewRequestBuilder.addTarget(mImageReader.getSurface());
It may be because your function startPreview() is not called, it can happens when we don't get surfaceTexture values at time.
This is my startPreview method
protected void createCameraPreview() {
try {
SurfaceTexture texture = textureView.getSurfaceTexture();
assert texture != null;
texture.setDefaultBufferSize(imageDimension.getWidth(), imageDimension.getHeight());
Surface surface = new Surface(texture);
captureRequestBuilder = cameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_PREVIEW);
captureRequestBuilder.addTarget(surface);
cameraDevice.createCaptureSession(Arrays.asList(surface), new CameraCaptureSession.StateCallback(){
#Override
public void onConfigured(#NonNull CameraCaptureSession cameraCaptureSession) {
//The camera is already closed
if (null == cameraDevice) {
return;
}
// When the session is ready, we start displaying the preview.
cameraCaptureSessions = cameraCaptureSession;
updatePreview();
}
#Override
public void onConfigureFailed(#NonNull CameraCaptureSession cameraCaptureSession) {
Toast.makeText(MainActivity.this, "Configuration change", Toast.LENGTH_SHORT).show();
}
}, null);
} catch (CameraAccessException e) {
e.printStackTrace();
}
}
Then i call updatePreview function to restart the preview
protected void updatePreview() {
if(null == cameraDevice) {
Log.e(TAG, "updatePreview error, return");
}
captureRequestBuilder.set(CaptureRequest.CONTROL_MODE, CameraMetadata.CONTROL_MODE_AUTO);
try {
cameraCaptureSessions.setRepeatingRequest(captureRequestBuilder.build(), null, mBackgroundHandler);
} catch (CameraAccessException e) {
e.printStackTrace();
}
}

Thanks
EDIT:
Solution thanks to the accepted answer
CamcorderProfile cpHigh = CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH);
mMediaRecorder.setProfile(cpHigh);
Try using a CamcorderProfile to set all the MediaRecorder resolution and quality settings first; you don't currently set many of the values, such as size. The MediaRecorder will not pay any attention to the dimensions of your SurfaceView, for one.
I'm building a camera app based on Camera2, but the picture I save is not matching the latest one I saw on my surface view. It seems that the Preview session works but when I ask for a capture, the new request stop the preview and capture the image. The surface view freeze on the latest pic and that create a gap between the time I press the shutter button (preview running and request capture) and the onCaptureCompleted from the capture request.
Here is the preview session
private void createCameraPreviewSession() {
try {
SurfaceTexture texture = mTextureView.getSurfaceTexture();
assert texture != null;
texture.setDefaultBufferSize(mPreviewSize.getWidth(), mPreviewSize.getHeight());
Log.d(TAG, "here is the width of texture" + mPreviewSize.getWidth());
Log.d(TAG, "here is the height of texture" +mPreviewSize.getHeight());
Surface surface = new Surface(texture);
mPreviewRequestBuilder
= mCameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_PREVIEW);
mPreviewRequestBuilder.addTarget(surface);
mCameraDevice.createCaptureSession(Arrays.asList(surface, mImageReader.getSurface()),
new CameraCaptureSession.StateCallback() {
#Override
public void onConfigured(#NonNull CameraCaptureSession cameraCaptureSession) {
if (null == mCameraDevice) {
return;
}
mCaptureSession = cameraCaptureSession;
try {
mPreviewRequest = mPreviewRequestBuilder.build();
mCaptureSession.setRepeatingRequest(mPreviewRequest,
mCaptureCallback, mBackgroundHandler);
} catch (CameraAccessException e) {
e.printStackTrace();
}
}
#Override
public void onConfigureFailed(
#NonNull CameraCaptureSession cameraCaptureSession) {
showToast("Failed");
}
}, null
);
} catch (CameraAccessException e) {
e.printStackTrace();
}
}
the mCaptureCallback is defined as below :
private CameraCaptureSession.CaptureCallback mCaptureCallback
= new CameraCaptureSession.CaptureCallback() {
private void process(CaptureResult result) {
switch (mState) {
case STATE_PREVIEW:
break;
case STATE_CAPTURE:
mState = STATE_PREVIEW;
capturePicture();
break;
}
}
#Override
public void onCaptureProgressed(#NonNull CameraCaptureSession session,
#NonNull CaptureRequest request,
#NonNull CaptureResult partialResult) {
process(partialResult);
}
#Override
public void onCaptureCompleted(#NonNull CameraCaptureSession session,
#NonNull CaptureRequest request,
#NonNull TotalCaptureResult result) {
TotalCaptureResult iResult = result;
Log.d(TAG, "Frame on Completed: "+result.getFrameNumber());
process(result);
}
}
What's happening is that I repeating the preview and it works. the process is just used to keep it running and nothing happened until the mState is set to CAPTURE.
It's set to capture when we click on the shutter button. When I click on the button, I call:
private void takePicture(){
try {
mFile = ImageSaver.generateNewFileImage();
mState = STATE_CAPTURE;
mCaptureSession.capture(mPreviewRequestBuilder.build(), mCaptureCallback,
mBackgroundHandler);
} catch (CameraAccessException e) {
Log.e(TAG,"Camera exception",e);
}
}
I call then CapturePicture as mState is in Capture as defined in the mCaptureCallback
private void capturePicture() {
mTakePictureRunnable = new Runnable() {
#Override
public void run() {
takePictureNow();
}
};
mBackgroundHandler.post(mTakePictureRunnable);
}
the takePicutreNow is defined
private void takePictureNow() {
Log.d(TAG, "Running captureStillPicture");
try {
if (null == mCameraDevice) {
return;
}
// This is the CaptureRequest.Builder that we use to take a picture.
final CaptureRequest.Builder captureBuilder =
mCameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_STILL_CAPTURE);
captureBuilder.addTarget(mImageReader.getSurface());
SurfaceTexture texture = mTextureView.getSurfaceTexture();
assert texture != null;
texture.setDefaultBufferSize(mPreviewSize.getWidth(), mPreviewSize.getHeight());
Log.d(TAG, "here is the width of texture" + mPreviewSize.getWidth());
Log.d(TAG, "here is the height of texture" + mPreviewSize.getHeight());
Surface surface = new Surface(texture);
captureBuilder.addTarget(surface);
// Orientation
int rotation = getWindowManager().getDefaultDisplay().getRotation();
captureBuilder.set(CaptureRequest.JPEG_ORIENTATION, ORIENTATIONS.get(rotation));
//Location if needed
boolean Location_Saved = CameraSettings.Instance().getBoolean(CameraSettings.SAVE_LOCATION,
getResources().getBoolean(R.bool.action_camera_settings_dflt_location));
if(Location_Saved == true) {
captureBuilder.set(CaptureRequest.JPEG_GPS_LOCATION, mLocationManager.getCurrentLocation());
} else {
captureBuilder.set(CaptureRequest.JPEG_GPS_LOCATION, null);
}
CameraCaptureSession.CaptureCallback CaptureCallback
= new CameraCaptureSession.CaptureCallback() {
#Override
public void onCaptureStarted(#NonNull CameraCaptureSession session,
#NonNull CaptureRequest request,
#NonNull long timestamp,
#NonNull long framenumber) {
playShutterSound();
showShutterAnimation();
}
#Override
public void onCaptureCompleted(#NonNull CameraCaptureSession session,
#NonNull CaptureRequest request,
#NonNull TotalCaptureResult result) {
Log.d(TAG, mFile.toString());
mState = STATE_PREVIEW;
}
};
mCaptureSession.capture(captureBuilder.build(), CaptureCallback, null);
mCaptureSession.stopRepeating();
} catch (CameraAccessException e) {
e.printStackTrace();
}
}
This process is working but I got a lag between the press and the imagesave and the latest pic I saw on the screen from the preview is not exactly the same saved if I move quickly.
It seems that the capture do not update the surface and the surface only show when we were in Preview
Any idea to see what I save ?
Thanks
The surface will freeze when you take an image, that might not be the image that gets saved. If you still want to show camera preview on the screen, you just have to restart the camera preview by calling the function you used to create preview at the first time.
