Answer 3

your manifest application name should contain application class name. Like

<application
        android:name="your package name.MyApplication"
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:largeHeap="true"
        android:theme="@style/AppTheme"> 

Answer 4

the steps I followed are:

1. close Android Studio (or IntelliJ IDEA)
2. in your project's directory:
   1. delete .idea directory
   2. delete .gradle directory
   3. delete all .iml files
      • find . | grep -e .iml$ | xargs rm
3. use Android Studio to re-open the directory as a project

Terminal commands:

# close Android Studio
cd "your project's directory"
rm -rf ./.idea
rm -rf ./.gradle
find . | grep -e .iml$ | xargs rm
# use Android Studio to re-open the directory as a project

Answer 5

Just remove this line from build.gradle(Project folder)

apply plugin: 'com.google.gms.google-services'

Now rebuild the application. works fine Happy coding
