Android-How to get User info from Firebase after logging in

With my current login activity, I can log in just fine, however I need to get Uid throughout my project.

This is my current login activity:

   //authenticate user
        firebaseAuth.signInWithEmailAndPassword(email, password)
                .addOnCompleteListener(LoginActivity.this, new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        // 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.
                        progressbar.setVisibility(View.GONE);
                        if (!task.isSuccessful()) {
                            // there was an error
                            if (password.length() < 6) {
                                lPass.setError(getString(R.string.minimum_password));
                            } else {
                                Toast.makeText(LoginActivity.this, getString(R.string.auth_failed), Toast.LENGTH_LONG).show();
                            }
                        } else {
                            Intent intent = new Intent(LoginActivity.this, MapsActivity.class);
                            startActivity(intent);
                            finish();
                        }
                    }
                });
    }
});

How do I get the user Uid from the login and have it be accessible to all my other activities? Thanks

You can get user info from the FirebaseUser object. In order to achieve this, please use the following code:

FirebaseAuth auth = FirebaseAuth.getInstance();
FirebaseAuth.AuthStateListener authListener = new FirebaseAuth.AuthStateListener() {
    @Override
    public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
        FirebaseUser firebaseUser = firebaseAuth.getCurrentUser();
        if (firebaseUser != null) {
            String userId = firebaseUser.getUid();
            String userEmail = firebaseUser.getEmail();
        } 
    }
};

FirebaseAuth.getInstance().getCurrentUser().getUid();

This line will give you the user ID.

Using FirebaseAuth you can get user uid,

  FirebaseAuth firebaseAuth = FirebaseAuth.getInstance();
FirebaseUser firebaseUser = firebaseAuth.getCurrentUser();
Log.d(TAG," UserId : "+firebaseUser.getUid()+" , DisplayName"+firebaseUser.getDisplayName());

This is a way to get all details available for user logged in from firebase.

FirebaseAuth mFirebaseAuth = FirebaseAuth.getInstance();
FirebaseUser mFirebaseUser = mFirebaseAuth.getCurrentUser();
// User Name
mFirebaseUser.getDisplayName();
// User ID
mFirebaseUser.getUid();
// Email-ID
mFirebaseUser.getEmail();
// User-Profile (if available)
mFirebaseUser.getPhotoUrl();
