java.lang.IllegalArgumentException: Bad argument passed to camera service on Lollipop

Question

I am developing an app that need to turn On Flash Light in android Lollipop (API 21 , 22)

But when I run it .

it show blew error , So I google it and found this link but I can't understand how to solve problem !!

it seems the problem is here mBuilder = mCameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_MANUAL);

Also my device have flash light and I set Camera permissions

My Class:

public class FlashLightUtilForL {
private CameraCaptureSession mSession;
private CaptureRequest.Builder mBuilder;
private CameraDevice mCameraDevice;
private CameraManager mCameraManager;

@SuppressLint("MissingPermission")
@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
public FlashLightUtilForL(Context context) {
    try {
        mCameraManager = (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);
        mCameraManager.openCamera("0", new MyCameraDeviceStateCallback(), null);

    } catch (Exception e) {
        e.printStackTrace();
    }
}

@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
class MyCameraDeviceStateCallback extends CameraDevice.StateCallback {

    @Override
    public void onOpened(CameraDevice camera) {
        mCameraDevice = camera;
        try {

            mBuilder = mCameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_MANUAL);
            List<Surface> list = new ArrayList<Surface>();
            Size size = getSmallestSize(mCameraDevice.getId());
            SurfaceTexture mSurfaceTexture = new SurfaceTexture(1);

            mSurfaceTexture.setDefaultBufferSize(size.getWidth(), size.getHeight());
            Surface mSurface = new Surface(mSurfaceTexture);
            list.add(mSurface);
            mBuilder.addTarget(mSurface);
            camera.createCaptureSession(list, new MyCameraCaptureSessionStateCallback(), null);
        } catch (CameraAccessException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onDisconnected(CameraDevice camera) {

    }

    @Override
    public void onError(CameraDevice camera, int error) {

    }
}

@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
private Size getSmallestSize(String cameraId) throws CameraAccessException {
    Size[] outputSizes = mCameraManager.getCameraCharacteristics(cameraId)
            .get(CameraCharacteristics.SCALER_STREAM_CONFIGURATION_MAP)
            .getOutputSizes(SurfaceTexture.class);
    if (outputSizes == null || outputSizes.length == 0) {
        throw new IllegalStateException(
                "Camera " + cameraId + "doesn't support any outputSize.");
    }
    Size chosen = outputSizes[0];
    for (Size s : outputSizes) {
        if (chosen.getWidth() >= s.getWidth() && chosen.getHeight() >= s.getHeight()) {
            chosen = s;
        }
    }
    return chosen;
}

/**

@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
class MyCameraCaptureSessionStateCallback extends CameraCaptureSession.StateCallback {

    @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
    @Override
    public void onConfigured(CameraCaptureSession session) {
        mSession = session;
        try {
            mSession.setRepeatingRequest(mBuilder.build(), null, null);
        } catch (CameraAccessException e) {

Answer 1

Try passing TEMPLATE_STILL_CAPTURE as a template value.

So this template is supported in all camera devices except DEPTH_OUTPUT devices that are not backward compatible as mentioned in google documentation.
