i´m not able to find any solution that solves my Problem.



I use Firebase and Facebook to sign up to my app.



When I first sign up to my app, i get the following screen:



Facebook First Login-Screen



I sign out from Firebase and Facebook using the following Lines of Code:



FirebaseAuth.getInstance().signOut();
LoginManager.getInstance().logOut();


When I´m trying after that to sign in with Facebook again, I get the following Screen:



Facebook Second Login-Screen



I´m only able to continue with the Account I used before.
I want to come back to the first Screen, where I have to enter E-Mail an Password so I could Sign in with another Facebook Account if I want.



On Stackoverflow I found the following promising Code:



FacebookSdk.sdkInitialize(getApplicationContext());
if (AccessToken.getCurrentAccessToken() != null)
new GraphRequest(AccessToken.getCurrentAccessToken(), "/me/permissions/", null, HttpMethod.DELETE, new GraphRequest.Callback()
@Override
public void onCompleted(GraphResponse graphResponse)
AccessToken.setCurrentAccessToken(null);
LoginManager.getInstance().logOut();

).executeAsync();



But this solved also not my Problem.



After that I get the following Screen:



Facebook alternate Second Login-Screen



I would by very thankful for any help and sorry for any English mistakes.
