In Android app Google Sign-In pop up does not load
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)
Solution
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.
