更改捆绑包saveInstanceState

Question

I want to create an app that acts as frontend to launch an emulator with preloaded game.

I have the emu source code, but I can't edit it. In the onCreate(Bundle savedInstanceState) method of the emulator's main activity there is this line:

if (savedInstanceState != null)
    currentGame = savedInstanceState.getString("currentGame");

Which seems the line that makes the emulator run the latest game if one is found when the activity is (re)created.

Is there a way to edit the savedInstanceState so that it contains the currentGame string?

Answer 1

when the activity is first created the savedInstanceState is null, and in subsequent calls it's not. To make sure that the savedInstanceState is not null, there is a method called onRestoreInstanceState() that you should override, and for sure it has the string you're looking for.

but i think that what you realy want is to send an intent to that activity with a Bundle already filled with that string. if it's not what you want please explain a little more what is your problem.
