I want build app with google account API. I done login with google tutorial and it work good but i try to logout account from another activity and it works too but method "onStart" in class LoginActivity.java login account back when i comment "onStart" its ok but when i try login again it login for account which was logged. For pass googleApiClient object to another activity i used singleton. Can you help me?
Code:
public void onStart() {
super.onStart();
OptionalPendingResult<GoogleSignInResult> opr = Auth.GoogleSignInApi.silentSignIn(mGoogleApiClient);
if (opr.isDone()) {
Log.d(TAG, "Got cached sign-in");
GoogleSignInResult result = opr.get();
handleSignInResult(result);
} else {
showProgressDialog();
opr.setResultCallback(new ResultCallback<GoogleSignInResult>() {
#Override
public void onResult(GoogleSignInResult googleSignInResult) {
hideProgressDialog();
handleSignInResult(googleSignInResult);
}
});
}
}
HomeActivity.java:
public class HomeActivity extends AppCompatActivity implements View.OnClickListener {
private GoogleApiClient mGoogleApiClient;// = state.getmGoogleApiClient();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
GlobalState state = ((GlobalState) getApplicationContext());
mGoogleApiClient = state.getmGoogleApiClient();
findViewById(R.id.sign_out_button).setOnClickListener(this);
}
private void signOut(){
Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(
new ResultCallback<Status>() {
#Override
public void onResult(Status status) {
GlobalState state = ((GlobalState) getApplicationContext());
state.setmGoogleApiClient(mGoogleApiClient);
Intent login = new Intent(getApplicationContext(), LoginActivity.class);
login.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(login);
finish();
}
});
}
#Override
public void onClick(View v) {
switch(v.getId()){
case R.id.sign_out_button:
signOut();
break;
}
}
change onStart() with
#Override
protected void onStart() {
super.onStart();
mGoogleApiClient.connect();
}
i resolve it by add onStart in HomeActivity:
#Override
protected void onStart() {
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.build();
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
mGoogleApiClient.connect();
super.onStart();
}

I need to get

D/123: pb with firebaseauth!
To be honest i do not understand in detail the behavior of the Firebase auth system that's why i'm stuck here.
Any idea?
I found out why it doesn't work :
#Override
protected void onDestroy() {
// FIREBASE LOGOUT
FirebaseAuth.getInstance().signOut();
// GOOGLE LOGOUT
GoogleSignInOptions gso = new GoogleSignInOptions.
Builder(GoogleSignInOptions.DEFAULT_SIGN_IN).
build();
GoogleSignInClient googleSignInClient = GoogleSignIn.getClient(ConnexionActivity.this, gso);
googleSignInClient.signOut();
// FACBOOK LOGOUT
LoginManager.getInstance().logOut();
super.onDestroy();
}
In my ConnectionActivity
This disconnected my FirebaseUser when i destroyed ConnexionActivity after each connexion of the user.
I switch it to my MainActivity which isn't destroyed until the app crash or the user forces it to close.
hi i am working on a android project where i am using firebase as back-end and i am building a signup and login form . When ever i sign up the code is working well and . When i try to retrieve it using "signInWithEmailAndPassword i am getting the fallowing error. The email address is badly formatted Firebase`
login Activity
public class login extends AppCompatActivity {
Button create_Account, login_btn;
EditText l_email, l_password;
FirebaseAuth fAuth;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
fAuth = FirebaseAuth.getInstance();
create_Account = findViewById(R.id.l_signup_btn);
create_Account.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(login.this, MainActivity.class));
}
});
l_password = findViewById(R.id.et_lpassword);
l_email = findViewById(R.id.et_lpassword);
login_btn = findViewById(R.id.l_login_btn);
login_btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (l_email.getText().toString().isEmpty()) {
l_email.setError("Email is Missing");
return;
}
if (l_password.getText().toString().isEmpty()) {
l_password.setError("Password is Missing");
return;
}
fAuth.signInWithEmailAndPassword(l_email.getText().toString(), l_password.getText().toString()).addOnSuccessListener(new OnSuccessListener<AuthResult>() {
#Override
public void onSuccess(AuthResult authResult) {
startActivity(new Intent(getApplicationContext(), dashboard.class));
finish();
}
}).addOnFailureListener(new OnFailureListener() {
#Override

}
#Override
protected void onStart() {
super.onStart();
if (FirebaseAuth.getInstance().getCurrentUser() != null) {
startActivity(new Intent(getApplicationContext(), dashboard.class));
finish();
}
}
}
Can you see what mistake you have
l_password = findViewById(R.id.et_lpassword);
l_email = findViewById(R.id.et_lpassword);
I have integrated Google authenticate login in my app but after once login if I log out my account still every time app automatically sign in the old user account.

}
});
}
//
}
I have used google docs about sign out but I can't solve my problem. I haven't found any useful questions from already asked by others.
I appreciate any help you folks can offer.
You also need to sign out from GoogleSignInClient and FirebaseAuth current user, something like this:
//sign out of the user and start login activity.
public void signOut() {
signOutBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.build();
GoogleSignInClient mGoogleSignInClient = GoogleSignIn.getClient(getContext(), gso);
mGoogleSignInClient.signOut();
FirebaseAuth.getInstance().signOut();
startActivity(new Intent(getContext(), LoginActivity.class));
}
});
}
When I try to sign out from GoogleApiClient I got the following error message
GoogleApiClient.isConnected() on a null object reference
Here is my code:
public static GoogleSignInOptions gso;
public static GoogleApiClient mGoogleApiClient;
//.........
google.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN).requestEmail().build();
mGoogleApiClient = new GoogleApiClient.Builder(getContext()).enableAutoManage(getActivity(), new GoogleApiClient.OnConnectionFailedListener() {
#Override
public void onConnectionFailed(#NonNull ConnectionResult connectionResult) {
Toast.makeText(getContext(), "Login failed", Toast.LENGTH_LONG).show();
}
}).addApi(Auth.GOOGLE_SIGN_IN_API, gso).build();
Intent intent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(intent, requestCode);
mGoogleApiClient.connect();
Toast.makeText(getContext(),"User Name "+ acc.getDisplayName()+ "Mail "+acc.getEmail(), Toast.LENGTH_LONG).show();
}
});
and my sign out code
public void signout(){
Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(new ResultCallback<Status>() {
#Override
public void onResult(#NonNull Status status) {
Intent intent1 = new Intent(getContext(),LoginActivity.class);
startActivity(intent1);
getActivity().finish();
}
});
And I also tried:
if (UserLogin.mGoogleApiClient.isConnected()) {
UserLogin.mGoogleApiClient.disconnect();
}
Try this...
Define:
public GoogleSignInOptions gso;
public GoogleApiClient mGoogleApiClient;
Initialize in Oncreate method:
gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.build();
mGoogleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
mGoogleApiClient.connect();
Now set click listener on signIn button
google.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(intent, requestCode);
Toast.makeText(getContext(),"User Name "+ acc.getDisplayName()+ "Mail "+acc.getEmail(), Toast.LENGTH_LONG).show();
}
});
/////
#Override
public void onConnectionFailed(ConnectionResult connectionResult) {
Toast.makeText(getContext(), "Login failed", Toast.LENGTH_LONG).show();
}
//Sign out
private void signOut() {
Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(
new ResultCallback<Status>() {
#Override
public void onResult(Status status) {
Intent intent1 = new Intent(getContext(),LoginActivity.class);
startActivity(intent1);
getActivity().finish();
}
});
}
Hope this will help you.
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?

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.
