Auth null i don't know problem. Why I can't not use Auth Firebase in my project.
public class LoginOrg extends AppCompatActivity {
private TextView mAddroom , mManageroom , tvName;
private Button LogoutBtn;
private String name,PositionUid;
private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener mAuthStateListener;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login_org);
Bundle bundle = getIntent().getExtras();
if (bundle != null) {
name = bundle.getString("putName");
}
PositionUid = mAuth.getCurrentUser().getUid();
bindWidget();
IntentOrg();
onStart();
}
private void bindWidget() {
mManageroom = (TextView) findViewById(R.id.manageRoomorg);
mAddroom = (TextView) findViewById(R.id.addRoomorg);
tvName = (TextView) findViewById(R.id.tvName);
tvName.setText(name);
LogoutBtn = (Button)findViewById(R.id.btnLogout);
mAuth = FirebaseAuth.getInstance();
mAuthStateListener = new FirebaseAuth.AuthStateListener() {
@Override
public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
if (firebaseAuth.getCurrentUser() == null) {
startActivity(new Intent(LoginOrg.this, PageLogin.class));
finish();
}else {
}
}
};
LogoutBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Logout();
}
});
}
@Override
protected void onStart() {
super.onStart();
mAuth.addAuthStateListener(mAuthStateListener);
}
private void IntentOrg() {
mManageroom.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(LoginOrg.this, OrgManageRoom.class);
i.putExtra("putName", tvName.getText().toString());
i.putExtra("putUid", PositionUid.toString());
startActivity(i);
}
});
mAddroom.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(LoginOrg.this,OrgRoom.class);
i.putExtra("putName",tvName.getText().toString());
startActivity(i);
}
});
}
}
