How to know if another application set the largeHeap or not programatically?

Question

I found some game apps use larger memory than the default limit (64MB in Nexus 7).

To achieve that, I assume they set the android:largeHeap="true"

In my codes, I want to check if an app set this flag or not. Any clue?

Check for ApplicationInfo objects with FLAG_LARGE_HEAP. You can get these objects from PackageManager (e.g., via getApplicationInfo()).

Thanks! May I double check the codes: `int flags = applicationInfo.flags; int isLargeHeap = (flags | applicationInfo.FLAG_LARGE_HEAP);` ? – JackWM Mar 03 '13 at 17:05
@JackWM: I think you want `&` and not `|`. http://stackoverflow.com/a/6067438/115145 – CommonsWare Mar 03 '13 at 17:42
