Help!
I have an activity that, instead of getting a response back from a
startActivityForResult, is destroyed (with no callbacks) when the
responding activity finishes!
The activity (call it GL) subclasses Activity and sets its contentView
to be a GLSurfaceView. This Activity overlays a MapView and uses
translucency to draw OpenGL objects over the Map.
Here are the details:
The app that uses Intents for a menu system.
An activity needing a menu does:
...startActivityForResult(intent, 0)
to fire off the menu (a ListView).
When the menu item is selected, the menu sets a result with:
........setResult(Activity.RESULT_OK, intent); menuActivity.finish();
In the originating activity, the onActivityResult should be called
with the results.
I have two activities - one where that works, one where it doesn't.
Both use the same common method to do the setActivityForResult call.
The first a MapActivity which is also the starting activity of my app.
It has no problem using the menu system to get results.
The second is the GL Activity, an Activity which sets it content to be
a GLSurfaceView.
This activity never sees onActivityResult after it sends the menu
intent, and it also vanishes without a trace (no lifecycle methods
called other than suspend()).
So the flow is like this:
MapView ---- intent ---> MenuActivity
displays list of choices
receives a click on a choice
sets a response
calls finish()
mapview.onActivityResult <-- called with result
mapview --- intent ---> Activity using GLSurfaceView
renders shape
gets a click
sends an intent ---intent-----
>MenuActivity
onSuspend called
displays list of choices
receives a click on a choice
sets a response
calls finish()
surfaceview activity vanishes <----
unexplained magic --------
Something odd is going on here!
Any ideas?
