im ended up fork and change the java codes by myself, and i add some try catch on turn on/off callback so i can handle if there’s exception occured.

file on SecondActivity.java

try {
  CodeUtils.isLightEnable(true);
  isLightOpen = true;
} catch (Exception e) {
  // Exception handler here
  Toast.makeText(getApplicationContext(), "Tidak bisa menyalakan senter", Toast.LENGTH_SHORT).show();
}

yeah i think so, in case you want to fix this issue ASAP, you can use that alternative. i’ve made a pull request for this. but i can’t wait for the maintainer accept this so right now im using custom fork until it accepted or fixed by them.

and also sorry for my bad english 😊
