I'm working on an app project for a company and I ended up getting into a problem I did not find how to fix it.
I'd like to limit access to certain parts of the app to different users.
Ex: I would like company administrators with their logins to see things in the app that employees, with their logins, could not see.
I'm using Firebase and Android Studio , I'd like to know if there's a class or API for it.
1. You have to have value that defines who is admin or user in your user bank. Example: level="admin" level="official"
You can use the Realtime Database Firebase. to create a new user. Example.
private void writeNewUserIfNeeded(final String userId, final String username, final String name) {
final DatabaseReference usersRef = rootRef.child("users").child(userId);
usersRef.addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
if (!dataSnapshot.exists())
usersRef.setValue(new User(username, name));
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
3.At each screen call that you want to limit to the user level you have to make a condition. Example:
if(user.nivel.equals("admin")){
//ABRIR A TELA PARA ADMIN
}else{
// BLOQUEADO!
}
You could add view conditions, for example:
By signing in the method would return the group that the user would belong to
public GrupoDeUsuario autenticar(usuario, senha){
}
boolean isAdm = GrupoDeUsuario.Administrador;
In your Views you could check and only show View if it was for the interest group
btnAcessoPeloAdm = findViewByID(R.id.btnAdm);
btnAcessoPeloAdm.setVisibility(isAdm ? View.VISIBLE : View.GONE);
