Closes without exception error

Hey dude,

So I managed to run your original code, however it terminates after one picture being taken?

Run log is shown below,

I/art: humin current process: com.hzitoun.camera2secretpicturetaker I/art: current process_level is : 0 I/HwSecImmHelper: mSecurityInputMethodService is null I/OpenGLRenderer: Initialized EGL, version 1.4 I/CameraManagerGlobal: Connecting to camera service I/PictureService: Taking picture from camera 0 W/ImageReader_JNI: Unable to acquire a lockedBuffer, very likely client tries to lock more than maxImages buffers I/Process: Sending signal. PID: 20732 SIG: 9 Application terminated.

Android Monitor does not show any errors or exceptions! It just closes!

VerifyError?

Hello,

I've been trying to understand your code as an android novice. But when running it locally on android studio, I get a verify error at

PictureService service =new PictureService(); service.startCapturing(PictureActivity.this, PictureActivity.this);

Any help is appreciated

How can we caputure images from both front and back camera ?

Pictures are very dark

Pictures captured are very dark and sometimes completely black.

onCaptureCompleted being called BEFORE OnImageAvailable

Hi,

I'm using the code almost exactly as is and am having an asynchronous issue where the onCaptureCompleted is being called before the onImageAvailable callback. The problem here is that when onCaptureCompleted is being called, it shows the picturesTaken map as empty because the pictureUrl hasn't been set yet in the saveImageToDisk method in the onImageAvailable callback.

Android 8 : saveImageToDisk fails because cameraDevice becomes null

On android Oreo (API 26) and for a completely unknown reason (at least so far), cameraDevice's value gets changed to null. Hence, it throws a NullPointerException.

Here is what I m doing

` /*Settings for Camera/
// captureBuilder.set(CaptureRequest.CONTROL_MODE, CameraMetadata.CONTROL_MODE_AUTO);
captureBuilder.set(CaptureRequest.JPEG_ORIENTATION, getOrientation());

    /**HDR*/
    captureBuilder.set(CaptureRequest.CONTROL_SCENE_MODE, CameraMetadata.CONTROL_SCENE_MODE_HDR);
    
    /**Settings for Flash*/
        captureBuilder.set(CaptureRequest.FLASH_MODE, CameraMetadata.FLASH_MODE_TORCH);

// captureBuilder.set(CaptureRequest.CONTROL_AWB_MODE, CaptureRequest.CONTROL_AWB_MODE_AUTO);

/**for White Balance */

        captureBuilder.set(CaptureRequest.CONTROL_AWB_MODE, CaptureRequest.CONTROL_AWB_MODE_AUTO);
            captureBuilder.set(CaptureRequest.COLOR_CORRECTION_MODE, CaptureRequest.CONTROL_AWB_MODE_AUTO);

How can I change settings and the Image i get is too dark ....
