Null result for GetInstance method call on librarySingleton #28

Closed Levieck closed 1 year ago

Hi,

_bleLibrary is null after this line of code: _bleLibrary = librarySingleton.CallStatic<AndroidJavaObject>("getInstance");

https://github.com/Velorexe/Unity-Android-Bluetooth-Low-Energy/blob/main/Assets/Scripts/BLE/BleManager.cs#L160

The project is excecuted in unity editor 2019.4.16f1 I have the following JDK, NDK, SDK settings: JDKSDKNDK

Do you have an idea why can getInstance return null?

Velorexe commented 1 year ago

Oof I would have no real clue. Is the librarySingleton null as well? Or is it just the _bleLibrary? It's possible that the Android package is not compiled with your APK, did you check if it's in the Android/Plugins directory?

Hi @Velorexe, thanks for the quick answer! You were right, when trying to build and run I got an error message about Java 11 instead of 8 compatibility issue. I'm working on fixing that.
