When Trying Turn Off Camera Led, App Crash

i have a code @TargetApi(23) private void setTorchMode( CameraManager cameraManager, String id, boolean switchOn) throws CameraAccessException { try { final M

Solution 1:

On some devices, if a flashlight is disabled and you try to disable it again, an app is crashed. So the solution is only to switch the state of the flashlight.

Solution 2:

public void turnOnFlashLight() {

    try {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            mCameraManager.setTorchMode(mCameraId, true);

            mTorchOnOffButton.setImageResource(R.drawable.on);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}


public void turnOffFlashLight() {

    try {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            mCameraManager.setTorchMode(mCameraId, false);

            mTorchOnOffButton.setImageResource(R.drawable.off);

        }

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