Question

When I am dealing with a usual Activity, then I open a database in onCreate and close it in onStop. When I deal with tab activities, then I add another open in onResume and another close in onPause.

So the code looks like this

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mDB.open();
}

@Override
protected void onResume() {
    super.onResume();

    mDB.open();
}

@Override
protected void onPause() {
    super.onPause();

    mDB.close();
}

@Override
protected void onStop() {
    super.onStop();

    mDB.close();
}

Is this too much of opening and closing?

I don’t think so. You are just managing lifecycle of the application, which is a very good thing.
