FirebaseAuth.getInstance() throwing exception java.lang.NoSuchMethodError

I'm implementing google sign-in using firebase, when I'm getting instance of firebaseauth class then its throws an exception,
java.lang.NoSuchMethodError
but my code is copied as it is from documentation(https://firebase.google.com/docs/auth/android/google-signin). Please help.
code:
public class LoginActivity extends AppCompatActivity {
private static final String TAG = "LoginActivity_Firebase";
private static final int RC_SIGN_IN = 9001;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
mAuth = FirebaseAuth.getInstance(); //this line is shown as error
//finding button and setting click listener
findViewById(R.id.signInButton).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
signIn();
}
});
}
void setupGoogleSignIn(){
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)

android - Firebase Google Authentication user not logging out

My MainActivity contains a GoogleSignIn button which pops up a menu with all the google accounts on the device. All works fine. The user is able to log in successfully, and directed to a new Activity.
Now, the new Activity (Main2Activity) contains a log-out button, which redirects the user to MainActivity again. But when I click on GoogleSignIn button again, the same user is again logged in. I want the account selection menu to pop up once again. What if the user wants to signin with other account?
Here's the signout code I'm using in Main2Activity:
HomeActivity/Main2Activity
findViewById(R.id.logoutButton).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v)
{
firebaseAuth.signOut();
startActivity(new Intent(getApplicationContext(), LoginActivity.class));
finish();
}
});
}
LoginActivity/MainActivity
package com.dell.nfclib;
public class LoginActivity extends Activity
{
private static final int RC_SIGN_IN = 101;
GoogleSignInClient mGoogleSignInClient;
private FirebaseAuth mAuth;
SignInButton signInButton;
#Override
protected void onStart()
{
super.onStart();
}
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
// Configure Google Sign In
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(getString(R.string.default_web_client_id))
.requestEmail()
.build();
// Build a GoogleSignInClient with the options specified by gso.
mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
// Initialize Firebase Auth
mAuth = FirebaseAuth.getInstance();
signInButton = (SignInButton) findViewById(R.id.googleSignInButton);
signInButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
signIn();
}
});
}
private 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);
// Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
if (requestCode == RC_SIGN_IN) {
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
if(result.isSuccess()) {
GoogleSignInAccount account = result.getSignInAccount();
firebaseAuthWithGoogle(account);
}
}
}
private void firebaseAuthWithGoogle(GoogleSignInAccount acct)
{
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())
{
// Sign in success, update UI with the signed-in user's information
// Get user details from the 'user' object..
startActivity(new Intent(getApplicationContext(), HomeActivity.class));
finish();
}
else
{
// If sign in fails, display a message to the user.
Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_LONG).show();
}
// ...
}
});
}
}

But when I click on GoogleSignIn button again, the same user is again logged in.
This is happening because you haven't signed out completely.
I want the account selection menu to pop up once again.
To solve this, you need to sign-out from both, Firebase and Google accounts. A method like the following can help you solve your problem:
private void signOut() {
FirebaseFirestore.getInstance().signOut(); //Sign-out Firebase
if (googleApiClient.isConnected()) {
Auth.GoogleSignInApi.signOut(googleApiClient); //Sign-out Google
}
}

Firebase There is no user record GoogleSingin

I am using Firebase Auth. I am trying to sing in a user with Google Account, using the signInWithCredential method. The credential from Google are ok, but when I try to sign in the user with firebase i get an error:
login error: signInWithCredential:failure com.google.firebase.auth.FirebaseAuthInvalidUserException: There is no user record corresponding to this identifier. The user may have been deleted. at com.google.android.gms.internal.zzdjy.zzak(Unknown Source:84) at com.google.android.gms.internal.zzdja.zza(Unknown Source:12)com.google.android.gms.internal.zzdki.zzal(Unknown Source:11)com.google.android.gms.internal.zzdkk.onFailure(Unknown Source:35)com.google.android.gms.internal.zzdka.onTransact(Unknown Source:79)android.os.Binder.execTransact(Binder.java:674)
I would understand the error if i would be singing in the user with email and password provider not with Google credentials.
And this error is from a new project so no users were ever authenticated.
I allready tried changing signingConfigs in gradle and changing the sha1 keys in firebase console. Deleted the project multiple times and i cant seem to get it to work.
It's weird because i remember that i had no problems in the past with this.
Help if you cant. Thank you.

Reinstalled Android Studio and everything is working now.

Android application takes too much time to start?

I'm finished with android app. Used firebase, admob. Has 31 activities. But when user installs the app for first time, the launch time is approximately 18 seconds which is too high. After first time launching, signup activity is there. But if we relaunch the app then it launches in 2 seconds. Why there is very high launch time? How can I reduce it? Below is my Sign up activity code. Using android studio 2.2
public class MainActivity extends AppCompatActivity {
private AdView mAdView;
private SignInButton mGoogleBtn;
private static final int RC_SIGN_IN=1;
private GoogleApiClient mGoogleApiClient;
private FirebaseAuth mAuth;
private static final String TAG="MAIN_ACTIVITY";
private FirebaseAuth.AuthStateListener mAuthListener;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mAuth=FirebaseAuth.getInstance();
mAuthListener=new FirebaseAuth.AuthStateListener() {
#Override
public void onAuthStateChanged(#NonNull FirebaseAuth firebaseAuth) {
if(firebaseAuth.getCurrentUser()!=null){
startActivity(new Intent(MainActivity.this,Home.class));
}
}
};
mGoogleBtn=(SignInButton)findViewById(R.id.view);
// Configure Google Sign In
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(getString(R.string.default_web_client_id))
.requestEmail()
.build();
mGoogleApiClient=new GoogleApiClient.Builder(getApplicationContext())
.enableAutoManage(this, new GoogleApiClient.OnConnectionFailedListener() {
#Override
public void onConnectionFailed(#NonNull ConnectionResult connectionResult) {
Toast.makeText(MainActivity.this,"Login via Google Failed! Press Skip",Toast.LENGTH_LONG).show();
}
})
.addApi(Auth.GOOGLE_SIGN_IN_API,gso)
.build();
mGoogleBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
signIn();
}
});
}
#Override
protected void onStart() {
super.onStart();
mAuth.addAuthStateListener(mAuthListener);
}
#Override

if (result.isSuccess()) {
// Google Sign In was successful, authenticate with Firebase
GoogleSignInAccount account = result.getSignInAccount();
firebaseAuthWithGoogle(account);
} else {
// Google Sign In failed, update UI appropriately
// ...
}
}
}
private void firebaseAuthWithGoogle(GoogleSignInAccount account) {
Log.d(TAG, "firebaseAuthWithGoogle:" + account.getId());
AuthCredential credential = GoogleAuthProvider.getCredential(account.getIdToken(), null);
mAuth.signInWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {

// If sign in fails, display a message to the user. If sign in succeeds
// the auth state listener will be notified and logic to handle the
// signed in user can be handled in the listener.
if (!task.isSuccessful()) {
Log.w(TAG, "signInWithCredential", task.getException());
Toast.makeText(MainActivity.this, "Authentication failed. Press Skip.",
Toast.LENGTH_SHORT).show();
}
else {
Toast.makeText(MainActivity.this,"Login Successful! Welcome to Unipune Buddy!",Toast.LENGTH_LONG).show();
}
// ...
}
});
}
private void signIn() {
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(signInIntent, RC_SIGN_IN);
}
public void mainscreen(View view){
Intent intent0=new Intent(this,Home.class);
Toast.makeText(MainActivity.this,"Signed in Successfully!",Toast.LENGTH_LONG).show();
startActivity(intent0);
}
}

I too had this issue, what i had done was disabling instant run in the project settings, and rebuilding the project, You can also use Cold start for engaging the user for the first time.

Launch activity automatically after Google Sign In - Android Studio

I'm trying to achieve something pretty simple since the last few days, but I didn't make it.
Basically, I used the sample app from Google Developers to create a login process for my app. I managed to login from Google when the Sign In button is clicked, and also to know if a user has already logged in and authenticated my app.
What I want to do is the following: when a user launches my app and is already logged in, I want to skip the login screen and automatically go to the next activity.
I made a bunch of tests but I will not post everything I tried here because it was sometimes pretty messy. Here the code I used for now:
My MainActivity.java:
public class MainActivity extends AppCompatActivity implements
GoogleApiClient.OnConnectionFailedListener,
View.OnClickListener {
private static final String TAG = "SignInActivity";
private static final int RC_SIGN_IN = 9001;
private GoogleApiClient mGoogleApiClient;
private ProgressDialog mProgressDialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Button listeners
findViewById(R.id.sign_in_button).setOnClickListener(this);
// [START configure_signin]
// Configure sign-in to request the user's ID, email address, and basic
// profile. ID and basic profile are included in DEFAULT_SIGN_IN.
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.build();
// [END configure_signin]
// [START build_client]
// Build a GoogleApiClient with access to the Google Sign-In API and the
// options specified by gso.
mGoogleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
// [END build_client]
// [START customize_button]
// Customize sign-in button. The sign-in button can be displayed in
// multiple sizes and color schemes. It can also be contextually
// rendered based on the requested scopes. For example. a red button may
// be displayed when Google+ scopes are requested, but a white button
// may be displayed when only basic profile is requested. Try adding the
// Scopes.PLUS_LOGIN scope to the GoogleSignInOptions to see the
// difference.
SignInButton signInButton = (SignInButton) findViewById(R.id.sign_in_button);
signInButton.setSize(SignInButton.SIZE_STANDARD);
signInButton.setScopes(gso.getScopeArray());
// [END customize_button]
}
#Override
public void onStart() {
super.onStart();
OptionalPendingResult<GoogleSignInResult> opr = Auth.GoogleSignInApi.silentSignIn(mGoogleApiClient);
if (opr.isDone()) {
// If the user's cached credentials are valid, the OptionalPendingResult will be "done"
// and the GoogleSignInResult will be available instantly.
Log.d(TAG, "Got cached sign-in");
GoogleSignInResult result = opr.get();
handleSignInResult(result);
} else {
// If the user has not previously signed in on this device or the sign-in has expired,
// this asynchronous branch will attempt to sign in the user silently. Cross-device
// single sign-on will occur in this branch.
showProgressDialog();
opr.setResultCallback(new ResultCallback<GoogleSignInResult>() {
#Override
public void onResult(GoogleSignInResult googleSignInResult) {
hideProgressDialog();
handleSignInResult(googleSignInResult);
}
});
}
}
// [START onActivityResult]
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
if (requestCode == RC_SIGN_IN) {
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
handleSignInResult(result);
}
}
// [END onActivityResult]
// [START handleSignInResult]
private void handleSignInResult(GoogleSignInResult result) {
Log.d(TAG, "handleSignInResult:" + result.isSuccess());
if (result.isSuccess()) {
// Signed in successfully, show authenticated UI.
GoogleSignInAccount acct = result.getSignInAccount();
updateUI(true);
Intent myIntent = new Intent(MainActivity.this, SplashScreen.class);
startActivity(myIntent);
finish();
} else {
// Signed out, show unauthenticated UI.
updateUI(false);
}
}
// [END handleSignInResult]
// [START signIn]
private void signIn() {
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(signInIntent, RC_SIGN_IN);
}
// [END signIn]
// [START signOut]
private void signOut() {
Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(
new ResultCallback<Status>() {
#Override
public void onResult(Status status) {
// [START_EXCLUDE]
updateUI(false);
// [END_EXCLUDE]
}
});
}
// [END signOut]
#Override
public void onConnectionFailed(ConnectionResult connectionResult) {
// An unresolvable error has occurred and Google APIs (including Sign-In) will not
// be available.
Log.d(TAG, "onConnectionFailed:" + connectionResult);
}
private void showProgressDialog() {
if (mProgressDialog == null) {
mProgressDialog = new ProgressDialog(this);
mProgressDialog.setMessage(getString(R.string.loading));
mProgressDialog.setIndeterminate(true);
}
mProgressDialog.show();
}
private void hideProgressDialog() {
if (mProgressDialog != null && mProgressDialog.isShowing()) {
mProgressDialog.hide();
}
}
private void updateUI(boolean signedIn) {
if (signedIn) {
findViewById(R.id.sign_in_button).setVisibility(View.GONE);
} else {
findViewById(R.id.sign_in_button).setVisibility(View.VISIBLE);
}
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.sign_in_button:
signIn();
break;
}
}
}
So my question is: how and where should I put my intent to go to the next activity?
Intent myIntent = new Intent(MainActivity.this, SplashScreen.class);
startActivity(myIntent);
Thank you very much for your help! Tell me if you need further details or explanations.

Put your activity class which you want to show after skipping login screen in YourClassAfterLogin.class
private void handleSignInResult(GoogleSignInResult result) {
Log.d(TAG, "handleSignInResult:" + result.isSuccess());
if (result.isSuccess()) {
// Signed in successfully, show authenticated UI.
GoogleSignInAccount acct = result.getSignInAccount();
updateUI(true);
Intent myIntent = new Intent(MainActivity.this, YourClassAfterLogin.class);
startActivity(myIntent);
finish();
} else {
// Signed out, show unauthenticated UI.
updateUI(false);
}
}

// [START handleSignInResult]
private void handleSignInResult(GoogleSignInResult result) {
Log.d(TAG, "handleSignInResult:" + result.isSuccess());
if (result.isSuccess()) {
// Signed in successfully, show authenticated UI.
GoogleSignInAccount acct = result.getSignInAccount();
updateUI(true);
Intent myIntent = new Intent(MainActivity.this, SplashScreen.class);
startActivity(myIntent);
finish();
} else {
// Signed out, show unauthenticated UI.
updateUI(false);
at isSuccess you can put your intent..
