Answer 1

Use this to get default preferences:

SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);

Use this to save a value:

Editor edit = preferences.edit();
edit.putString("isPayed", "yes");
edit.apply(); 

and this to retrieve the value: preferences.getString("isPayed", "No");

Answer 2

You could try SharedPreferences. Whenever the payment activity is complete set the flag as 1.

Eg.

int flag = entry.getInt("flag",0);
if(flag==0)
{
// Payment alert
// Payment finished
// editor.putInt("flag", ++flag);
// editor.commit();
}
else 
{
//Don't display the dialog
}

In this way as the user finishes the payment set the flag as 1.
