how to use three different layauts for one project in android studio code example

Example 1: how to store some variables on the device in unity

//Example using the PlayerPrefs system to store integers on the local device storage
//Writing data
PlayerPrefs.SetInt("myPref", 5);
//Reading data
myint = PlayerPrefs.GetInt("myInt");

Example 2: Android dependency 'androidx.core:core' has different version for the compile (1.0.2) and runtime (1.1.0) classpath. You should manually set the same version via DependencyResolution

I solved it by upgrading my gradle dependency in the android/build.gradle file: classpath 'com.android.tools.build:gradle:3.3.1' (I was previously on version 3.2.1)
