greenDAO Android no create tables in file database

Question

I took the guide of https://blog.mindorks.com/powerful-android-orm-greendao-3-tutorial to integrate greenDAO in my android project, I follow everything (or so I think XD) and when I try on my mobile it is not created the tables, create the database file but when I open it with a viewer it doesn't show me anything.

I do not have how to test in the emulator to see if it is a problem of the mobile or of some permission that I need.

I will leave the project to see if you can help me, thank you very much.

Just check your project, it's working well. In MainActivity you can query and set to textView, remember set your textview id is nameTv:

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    TextView textView = (TextView) findViewById(R.id.nameTv);

    // Put this in a different thread or use AsyncSession in greenDAO.
    // For Demo purpose, this query is made on main thread but it should in a different thread.
    M_User user = ((AppDbController)getApplication()).getDaoSession().getM_UserDao().load(1L);

    if(user != null){
        textView.setText(user.getFullName());
    }
}

}
