In Android app Google Sign-In pop up does not load

Question

Whenever I try to sign in by launching the google sign-in intent, it directly goes to the onActivityResult without me having the chance to choose an account. All It does is dimm the screen, but the window to select an account doesn't show up. The Login then fails with this ApiException:

java.lang.ClassNotFoundException: com.google.android.gms.common.api.Scope

and

java.lang.RuntimeException: Canvas: trying to draw too large(256000000bytes) bitmap.

(full stack trace: https://pastebin.com/vBZeBLu0)

All of my used dependencies are up to date and my credentials (oAuth client-id) are all set up correctly, I tried the solutions of other similar problems, but none of them solved my issue, i also checked if the user is logged out completely from the device and the issue kept reaccuring.

This is my Log-in Activity:

public class Login extends Activity implements GoogleApiClient.OnConnectionFailedListener, GoogleApiClient.ConnectionCallbacks  {                                   

private static final String TAG = "LoginProcess";

SignInButton gsignInButton;
private static final int RC_SIGN_IN = 1;
DatabaseReference mRef;
FirebaseAuth mAuth;
FirebaseAuth.AuthStateListener mAuthListener;
GoogleSignInOptions gso;
GoogleApiClient mGoogleApiClient;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.welcomescreenlogin);

    mAuth = FirebaseAuth.getInstance();



    gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken(getString(R.string.default_web_client_id))
            .requestEmail()
            .build();

    mGoogleSignInClient = GoogleSignIn.getClient(this, gso);

    gsignInButton = findViewById(R.id.sib);

    gsignInButton.setColorScheme(SignInButton.COLOR_DARK); // wide button style
    gsignInButton.setOnClickListener(myhandler);


}

View.OnClickListener myhandler = new View.OnClickListener() {
    public void onClick(View v) {
       signIn();
    }

};



public void signIn() {

    Intent signInIntent = mGoogleSignInClient.getSignInIntent();
    startActivityForResult(signInIntent, RC_SIGN_IN);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == RC_SIGN_IN) {
        Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
        try {
            // Google Sign In was successful, authenticate with Firebase
            GoogleSignInAccount account = task.getResult(ApiException.class);
            firebaseAuthWithGoogle(account);
        } catch (ApiException e) {
            // Google Sign In failed, update UI appropriately
            Log.w(TAG, "Google sign in failed", e);  //this is where it always lands.
            Toast.makeText(this, "login failed", Toast.LENGTH_SHORT).show();
            // ...
        }
    }

}

I have no idea what the cause of the problem is, how can i solve this issue and make the account selection window pop up?

EDIT 2.1.2019

Instead of the above ApiExeption i get this error:

W/LoginProcess: Google sign in failed

I believe something went wrong with how i set up my oAuth (Auto generated by Firebase)

Answer 1

Option 1 - Make sure the Google Sign-in is enabled in the Firebase Authentication methods in Firebase console. By default, Google Sign-in is not enabled.

Option 2 - Inside your AndroidManifest.xml file, under the tag add the following lines to support high memory support in case the Google Sign-in popup requires more memory. Even large images can be loaded using this command in application tag - largeHeap as true ~ your launcher image in this case.

<application
    android:hardwareAccelerated="true"
    android:largeHeap="true" >

Option 3 - Try this code to implement the Google Sign-in using Firebase and it should work.

public class LoginActivity extends AppCompatActivity {

private GoogleSignInClient mGoogleSignInClient;
private FirebaseAuth mAuth;
private int permissions = 0;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);
    SignInButton authButton = findViewById(R.id.home_auth_button);
    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken("xxxxxxxxxxxx.apps.googleusercontent.com").requestEmail().build();
    mAuth = FirebaseAuth.getInstance();
    mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
    authButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            signIn();
        }
    });
}

private void signIn() {
    Intent signInIntent = mGoogleSignInClient.getSignInIntent();
    startActivityForResult(signInIntent, 0);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == 0) {
        Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
        try {
            GoogleSignInAccount account = task.getResult(ApiException.class);
            if (account != null) {
                firebaseAuthWithGoogle(account);
            } else{
                Log.w("AUTH", "Account is NULL");
                Toast.makeText(LoginActivity.this, "Sign-in failed, try again later.", Toast.LENGTH_LONG).show();
            }
        } catch (ApiException e) {
            Log.w("AUTH", "Google sign in failed", e);
            Toast.makeText(LoginActivity.this, "Sign-in failed, try again later.", Toast.LENGTH_LONG).show();
        }
    }
}

private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
    Log.d("AUTH", "firebaseAuthWithGoogle:" + acct.getId());
    AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (task.isSuccessful()) {
                        Log.d("AUTH", "signInWithCredential:success");
                        startActivity(new Intent(LoginActivity.this, AnotherActivity.class));
                        Toast.makeText(LoginActivity.this, "Sign-in successful!", Toast.LENGTH_LONG).show();
                    } else {
                        Log.w("AUTH", "signInWithCredential:failure", task.getException());
                        Toast.makeText(LoginActivity.this, "Sign-in failed, try again later.", Toast.LENGTH_LONG).show();
                    }
                }
            });
    }
}

Look out for the GoogleSignInOptions.Builder where you need to pass the requestIdToken("xxxx") with the builder. It's a URL which you can find it under Firebase Authentication Tab -> Sign-in Methods -> Google -> Web SDK Configuration -> Web Client ID.

Hope this answers your query.

Answer 2

So as expected, this was due to

Canvas: trying to draw too large(256000000bytes) bitmap.

The launcher icon that you had used, which also appeared in the account chooser dialog, was stopping the dialog from popping.
As a solution, you may follow Praveen's answer (option2) about making the app support the larger images from Manifest.
But I suggest you to compress the image file because the account chooser dialog doesn't really need a hi-res image and neither the launcher icon need to be that big. Take a look at this, scale the launcher icons to those sizes(only that you need) and put them in respective drawable folders so that it might help you avoid similar issues in future as well.

Answer 3

Google sign in success fully but our api login/sign up response are failed at that time second time click on "Google sing" button at that time Google account selection dialogue not appear,

first of all, check your Google login sign in or not,

and then clear it.

fun googleLogin() {

        val gso = GoogleSignInOptions
            .Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .requestProfile()
            .build()

        val mGoogleSignInClient = GoogleSignIn.getClient(this, gso)

        //check google login sign in or not
        val account = GoogleSignIn.getLastSignedInAccount(this)
        if(account==null){
            val signInIntent = mGoogleSignInClient.signInIntent
            startActivityForResult(signInIntent, REQUEST_CODE_GOOGLE_SIGN_IN)
        }else{
            // clear account  
            revokeAccess(mGoogleSignInClient)
        }

    } 

remove already login account

private fun revokeAccess(mGoogleSignInClient: GoogleSignInClient) {
        mGoogleSignInClient.revokeAccess()
            .addOnCompleteListener(this, OnCompleteListener<Void?> {
                // ...
                val signInIntent = mGoogleSignInClient.signInIntent
                startActivityForResult(signInIntent, REQUEST_CODE_GOOGLE_SIGN_IN)
            })
    }
