当我想运行我的项目时发生了崩溃

Question

I'm still new in learning about Android application. I had a crash when I tried to run my Mainactivity. I designed a register layout, and I was trying to save all the registration information in Firebase, but the crash prevented me even from testing whether the database is working or not.

I have executed the app many times, and this is what Logcat told me:

You need to edit your Application class that extends from android.app.Application and initialize Firebase in the entire application process.

public class TestApplication extends Application {
  @Override
  public void onCreate() {
    super.onCreate();
    FirebaseApp.initializeApp(this);
  }
}

I found one solution for this issue and I want to share that with you. I had to go back and modify the dependencies in build.gradle

dependencies {
    classpath 'com.android.tools.build:gradle:3.3.0'
    classpath 'com.google.gms:google-services:4.2.0'

}`

and Also modify

dependencies {

implementation 'com.google.firebase:firebase-auth:16.0.5'
implementation 'com.google.firebase:firebase-core:16.0.5'
implementation 'com.google.firebase:firebase-database:16.0.5'
implementation 'com.google.firebase:firebase-storage:16.0.5'

}

According to Lovish-Pandey wrote that make sure that all the firebase dependencies have the same import version
