Unable to select different account on google Sign In

I'm using firebase and google sign in. The problem is that when I click on the sign in button, it log in automatically even without any google account registered in firebase auth users! Also the "choose account" dialog doesn't appear when user isn't in firebase auth users and when it is. I would like to show this dialog.

You are setting click here
switch (view.getId()) {
case R.id.sign_in_button:
signIn();
As per this code you need to use
btnSignIn.setOnClickListener(this);
Instead of
findViewById(R.id.sign_in_button).setOnClickListener(this);

So the problem is when I am logged in then trying to go back to my Homepage activity it stopped. So I need help from experts to solve it. It'll be a pleasure if you help me in this task.
My gradle file:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'

compile 'com.google.firebase:firebase-storage:10.0.1'
compile 'com.firebaseui:firebase-ui-database:0.4.0'
}
apply plugin: 'com.google.gms.google-services'

Did you try to change your Login activity as follows? Here, I'm checking if the user is already logged in in the Login activity, and if it is I'm calling the HomePage activity.
public class Login extends AppCompatActivity {
private EditText inputEmail, inputPassword;
private FirebaseAuth auth;
private ProgressBar progressBar;
private Button btnSignup, btnLogin;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

if (auth.getCurrentUser() != null) {

startActivity(intent);
finish();
}
setContentView(R.layout.activity_login);
ColorDrawable colorDrawable=new ColorDrawable(Color.parseColor("#bc212b"));

return;
}
if (TextUtils.isEmpty(password)) {

}
} else {
Intent intent = new Intent(Login.this, HomePage.class);

Hope this can match your requirements

Firebase Authentication Error

I am new to android studio and Firebase. After watching some online tutorials I wrote the code for a login page. Can anyone please debug it for me?
Please note that my login button is an image view
The name of the app is Riddler

super.onStop();
if (authStateListener != null) {
auth.removeAuthStateListener(authStateListener);
}
}
#Override
public void onConnectionFailed(#NonNull ConnectionResult connectionResult) {
}
private void SignOut() {
//Firebase sign out
if (auth.getCurrentUser() != null) {
auth.signOut();
Log.i("LoginActivity","Firebase logout successfully");
}
//Facebook SignOut
LoginManager.getInstance().logOut();
}
#Override

}
}

If you are reading data from Firebase's real time database, the default read database permission is set to false. You can modify it to true from the database's permission tab.
