public class MainActivity extends AppCompatActivity implements View.OnClickListener{
private static final int RC_SIGN_IN=0;
FirebaseAuth auth;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FirebaseAuth auth=FirebaseAuth.getInstance();
if(auth.getCurrentUser()!=null)
{
Log.d("AUTH",auth.getCurrentUser().getEmail());
}
else {
startActivityForResult(AuthUI.getInstance()
.createSignInIntentBuilder().setProviders(
AuthUI.FACEBOOK_PROVIDER,
AuthUI.GOOGLE_PROVIDER,
AuthUI.EMAIL_PROVIDER
).build(), RC_SIGN_IN);
}
findViewById(R.id.btnLogout).setOnClickListener(this);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==RC_SIGN_IN)

if(resultCode==RESULT_OK)

Log.d("AUTH",auth.getCurrentUser().getEmail());
}
else
{
Log.d("AUTH","Not authenticated");
}
}
}
@Override
public void onClick(View view) {
if(view.getId()==R.id.btnLogout)

AuthUI.getInstance().signOut(this).addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
Log.d("AUTH","User logged Out");
finish();
}
});
}
}
}
