Answer 1

I have also faced same problem with Firebase when run application below API 19(< 4.4.2) devices due to error of Multidex. Then below solution work for me:

In app module build.gradle

android {
   ...
   defaultConfig {
       multiDexEnabled true
       ...
   }
}

dependencies {
  // add dependency 
  compile 'com.android.support:multidex:1.0.1'
}

// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'

update name in AndroidManifest.xml

     // ...

Crate a MyApplication.java file

public class MyApplication extends Application {

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

}
