I have successfully captured the single photo using camera in Android. But when I tried to capture 5 photos at once, app stops responding, camera preview turns to green and

Answer 1

You can take next photo only after callback method Camera.PictureCallback.onPictureTaken is called and camera preview is restarted.

private void takePhoto() {
    if (!(cameraPreview.isRunning())) {
        Log.i(LOG_TAG, "Camera is not ready. Skip frame");
        return;
    }

    camera.takePicture(null, null, this);
    cameraPreview.onPictureTook();
}

public void onPictureTaken(byte[] data, Camera camera) {
    // save photo
    cameraPreview.start();
}


public class CameraPreview extends SurfaceView {

    private boolean previewRunning = false;

    /**
     * Should be called after calling camera.takePicture
     */
    public void onPictureTook() {
        previewRunning = false;
    }

    public boolean isRunning() {
        return previewRunning;
    }

    public void start() {
        try {
            camera.setPreviewDisplay(surfaceHolder);
            camera.startPreview();
            previewRunning = true;
        } catch (Exception ignored) {
            Log.e(LOG_TAG, "Error starting camera preview", ignored);
        }
    }
}
