this issue occured on my app too, is there any solution about this?

same problem here. it would be helpful if there was an option to disable/hide the flashlight.

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();
}

that is a good interim solution, thanks for posting it. this should be part of the baseline functionality of the package. maintaining custom forks can be problematic in terms of future updates and fixes.

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 :")
