onActivityResult no longer being called after onDestroy

Question

onActivityResult is giving me major headaches. My little game has a title / menu screen. Upon clicking "new game" an Activity is launched which creates a SurfaceView for my game world.

When playing, the player can enter buildings in the game world. Upon entering a building I launch the activity for that particular building from my SurfaveView. Here is an example:

   Intent storeIntent = new Intent(mMinerClass, GeneralStore.class);
   storeIntent.putExtra("player", mPlayer.save());   
    ((Activity) mContext).startActivityForResult(storeIntent, Miner.REQUEST_STORE);

mMinerClass is defined in the game Activity onCreate:

  mMap .mMinerClass = Miner.this;

mMap is the SurfaceView. I'm passing a bundle containing the state of the player. In onActivityResult I grab the bundle returned by the store activity and update the player state.

 public void onActivityResult(int requestCode, int resultCode, Intent intent) {
      Bundle player = intent.getExtras();
      mMap.mSavedPlayer = player;
  }

mSavedPlayer is later used to set the new player state.

All the above works generally

I can enter stores, buy stuff, leave and the player is updated correctly.

The problem manifests when I press the Home button (or someyimes back button) and onDestroy gets called. My onDestroy method does nothing besides call super.onDestroy();

After onDestroy() gets called onActivityResult no longer gets called.

So:

1) I play the game, everthing works great.

2) I press home and ondestroy is called

3) relaunch my game via launcher icon

4) Resume game. I can still enter and leave stores but onActivityResult is no longer called.

Here is some logcat output. I'm logging each time I enter a relevant method.

  App start.  Resuming a saved game

I'm posting this from my phone so excuse any dumb typos.

I appreciate any insight y'all can provide regarding this. Thanks!

Answer 1

You should put additional attention to this line:

((Activity) mContext).startActivityForResult(storeIntent, Miner.REQUEST_STORE)

Are you sure mContext is the correct activity? I suspect it's not the current activity but the reference to another activity instance, the first one that was closed before. Can you use "this" instead of mContext?
