Androidx MutliDex: The Number Of Method References In A .dex File Cannot Exceed 64K

Answer :

Modify the module-level build.gradle file to enable multidex and add the multidex library as a dependency, as shown here:

android {     defaultConfig {         ...         minSdkVersion 16          targetSdkVersion 28         multiDexEnabled true     }     ... }  dependencies {   implementation 'com.android.support:multidex:1.0.3' } 

If you do not override the Application class, edit your manifest file to set android:name in the tag as follows:

    <?xml version="1.0" encoding="utf-8"?>     <manifest xmlns:android="http://schemas.android.com/apk/res/android"         package="com.example.myapp">         <application                 android:name="android.support.multidex.MultiDexApplication" >             ...         </application> </manifest> 

If you do override the Application class, change it to extend MultiDexApplication (if possible) as follows:

... import androidx.multidex.MultiDexApplication; ... public class MyApplication extends MultiDexApplication { ... } 

Or if you do override the Application class but it's not possible to change the base class, then you can instead override the attachBaseContext() method and call MultiDex.install(this) to enable multidex:

public class MyApplication extends SomeOtherApplication {   @Override   protected void attachBaseContext(Context base) {      super.attachBaseContext(base);      MultiDex.install(this);   } }
