@paulwong-madmadgroup @ParkSangGwon same here.... I solved this issue and send pull request. (#60) plz check it.

Same issue, here.

I get the same issue when I go to the settings from dialog with denied message, switch off permissions that were previously switched on and go back to my app. Fix this, please.

@insectkorea @octokim hey friends, did you check #60? I think it can fix issue. 👍

[octokim]

@JSpiner can you explain, where your runtime exceptions should be handled?

[JSpiner]

@octokim First, you must prevent it from calling twice. Using loading dialog, disable view, add click flag..... etc.

And check like below.

try{
    TedPermission.with(context)
                    .setPermissionListener(listener)
                    .setPermissions(permissionString)
                    .check();
}
catch(RuntimException error){
    Logger.d("it called twice, somethings wrong...");
}

In fact, it is not fixed. Because the listener is a static field. In other words, only one can be assigned. If you want to correct errors instead of exception handling, you need to fix a lot of things. 😂

[octokim]

@JSpiner seems good ^_^

This error solved at v2.1.0 Please update library version.
