You could always set a bool value in the android.content.SharedPreferences, then in the first oncreate() check to see whether that bool value is false.

If it is push the license screen intent and perform a check for application, if its there update the preference to true. So on next start it will skip over it, where you can load your main screen.

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

settings = getSharedPreferences(PREFS_NAME, 0);
boolean enteredDetails = settings.getBoolean("FirstTime", false);



if(enteredDetails){
setContentView(R.layout.main); //loads the main screen            
}
else{
startActivityForResult(new Intent(this, License.class), GET_DETAILS); 
}
}
