    Hello, I am trying to make an android application in Unity for practice with native Android code.
    I am using Jar libraries created in Android studio.
    This app is supposed to send an SMS message directly from my Unity application.
    The code is tested as it works in the android studio build. But when I call it from unity I got a problem, this is the error :
    2022/11/22 12:00:25.043 19878 19907 Error Unity java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/core/app/ActivityCompat;

    And this is where the error occurs: ActivityCompat.requestPermissions(unityActivity,new String[]{Manifest.permission.SEND_SMS},1);

    I tried placing jar libraries: appcompat-resources-1.4.1, support-v4-28.0.0, core-ktx-1.9.0 in my android/plugins/folder but the error is still there.

    Does anyone have experience with asking for permissions that are outside of Unity-s documentation?
