BLUETOOTH_SCAN permission issue (android 11+) #32

Closed mmar58 closed 1 year ago

mmar58 commented 1 year ago

Hi, I am running your project on my device and found this issue

Exception: AndroidJavaException: java.lang.SecurityException: Need android.permission.BLUETOOTH_SCAN permission for android.content.AttributionSource@4d29c837: GattService registerScanner

And as I was investigating more, I found that on Android 11+ plus devices, this problem is happening because of the permission security change and I also found the solution.

But here are some codes which you will have to add inside the jar files. So if you add those and update your project, I will be grateful and it can help a lot of us.

Hi @mmar58

Thanks for the heads up! I've always had an annoyance against the permissions on different version of Android (and on their API). Just a question, which version of the plugin are you using? There's a v0.0.3-alpha.0 build that's currently experimental, but has overhauled the way permissions are handled. It does require a different way of using the framework, but it should be more straight forward.

If you aren't using the new v0.0.3-alpha.0 version (or can't switch due to restraints), I'll take a look at adding a permissions check and update the .jar file accordingly.

Hi, I have fixed this issue by asking permission inside Unity. I am creating a pull request now. But hope you can organize the permissions in a good way
