Compile Error: Caused by: java.lang.ClassNotFoundException: Didn't find class "com.google.firebase.provider.FirebaseInitProvider"

  • 772

I have this problem when compiling my DEBUG app on 4.4, on 8.1 it works perfectly.

I have read many questions about this error but it does not solve the problem, I do not know what to do, my version of Android Studio is 3.5, so it does not have Instant Run

Caused by: java.lang.ClassNotFoundException: Didn't find class "com.google.firebase.provider.FirebaseInitProvider" on path: DexPathList[[zip file "/data/app/com.app-2.apk"],nativeLibraryDirectories =[/data/app-lib/com.app-2, /vendor/lib, /system/lib]]

This is my gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.app"
        minSdkVersion 17
        targetSdkVersion 28
        versionCode 35
        versionName "4.3"
        multiDexEnabled true
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

    Implement the method attachBaseContext()and there initialize the multidex mode

    public class MyApplication extends Application {

    @Override 
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
    } 

    @Override
    public void onCreate() {
        super.onCreate();

       // MultiDex.install(this);   
    }

}
