Camera Preview after take a photo

[RHoumaidy]

Hello,

I am using the Camera fragment, and here is my problem: when i take a photo the camera fragment preview the captured photo and no live preview of the camera shown again, i need to take a series of photos without previewing the captured photo, right now i am recreating the hole activity in order to clear the camera preview - and that is not a efficient solution - please help me or guide me to another solution

Bests,

cant you just show/hide an imageView with the captured image?

[RHoumaidy]

@wengelef the problem is after taking a photo, a preview of the captured image is showed instead of the live preview of the camera, I want to take multiple images without preview them after capture,

[wengelef]

are you starting the PreviewActivity in the ResultListener? If so, just skip that step.

I am having the same issue. and i am not calling the PreviewActivity. Can you please elaborate with code

[RHoumaidy]

@arshdoda right now I just recreate the Camera Fragment after take a photo, but this cause a black screen for 2 or 3 second for re-initializing the camera

[RHoumaidy]

@wengelef that's exactly my problem, I skipped starting the PreviewCamera, and now the camera fragment just showing the captured photo,

[wengelef]

interesting, will look into it tomorrow

[wengelef]

did you check the sample app? I cannot reproduce your problem.

[arshdoda]

yes when picture is captured it shows the image in the fragment

[RHoumaidy]

@wengelef the sample app show the preview activity, I am asking if there is a way to capture multiple images without preview any one, if i don't show the preview activity, the capture image showed in the fragment @arshdoda , and can't take another image.

@wengelef the sample app show the preview activity, I am asking if there is a way to capture multiple images without preview any one, if i don't show the preview activity, the capture image showed in the fragment @arshdoda , and can't take another image.

CameraFragmentMainActivity doesn't show a Preview, just a Toast and it seems to fit exactly what you need to do. I really can't reproduce your Problem with a bunch of devices. Which device and SDK version are you deploying on?

@wengelef I tried with CameraFragmentMainActivity. It first apture image then shows the toast of image path and the screen freezes. Then, i clicked again on the capture button App crashes with error:

[wengelef]

okay, i could actually reproduce the behavior in the Sample App with a Galaxy S5. Did you ever solve your Problem? When i rapidly start CameraFragments i get #24

You have to change Camera1Manager.java to continue showing preview.

camera.startPreview();

public void takePhoto(File photoFile, final CameraPhotoListener cameraPhotoListener, final CameraFragmentResultListener callback) {
        this.outputPath = photoFile;
        this.photoListener = cameraPhotoListener;
        EventBus.getDefault().post(new RecordStateEvent(RecordStateEvent.State.Photo));
        backgroundHandler.post(new Runnable() {
            @Override
            public void run() {
                setCameraPhotoQuality(camera);
                try {
                    camera.takePicture(null, null, new Camera.PictureCallback() {
                        @Override
                        public void onPictureTaken(byte[] bytes, Camera camera) {
                            Camera1Manager.this.onPictureTaken(bytes, camera, callback);
                            camera.startPreview();
                        }
                    });
                } catch (Exception e) {
                    Log.e(TAG, "takePhoto error: "+e.getMessage()+" (usually caused by a double tap on photo trigger)");
                    if(cameraPhotoListener!=null)
                        cameraPhotoListener.onPhotoTakeError();
                }
            }
        });
    }
