There's no simple answer to this; you can use as much memory as the device has, minus what it's using for other programs. When Android thinks it's low on memory, it'll start killing background tasks, so it's a soft limit. Most devices do not have swap space. You can get some statistics about the device's memory from inside Dalvik with android.app.ActivityManager.MemoryInfo (I assume there's an NDK equivalent).
