My android app is getting an "Out of memory" error without a useful
stack trace. It occurs after I have repeatedly re-invoked its main
logic through a menu interaction, which leads me to believe that
there's a memory leak somewhere.
I say that the stack trace isn't useful because it doesn't include
references to any of my own code. There are no references to my own
code in the logcat output, either.
I'm wondering if any of you can help me figure out where my memory
leak might be occurring, given my stack trace and my logcat output.
Here's the stack trace:
Thread [<3> main] (Suspended (exception OutOfMemoryError))
ViewRoot.handleMessage(Message) line: 1716
ViewRoot(Handler).dispatchMessage(Message) line: 99
Looper.loop() line: 123
ActivityThread.main(String[]) line: 4203
Method.invokeNative(Object, Object[], Class, Class[], Class, int,
boolean) line: not available [native method]
Method.invoke(Object, Object...) line: 521
ZygoteInit$MethodAndArgsCaller.run() line: 791
ZygoteInit.main(String[]) line: 549
NativeStart.main(String[]) line: not available [native method]
... and here's the logcat output:
[ ... lots of repetitions of the following WARN messages as I
repeatedly invoke my app's main logic via a menu selection ... ]

allocation too large for this process.

bytes
Could my error be related to the "Window already focused ..."
warnings? If so, how can I find out what is causing these?
I know that I could sprinkle my code with lots of calls to Log.v() in
order to zero in on where my problem might be occurring, but I'm
wondering if there is a better way to get more meaningful information
about the cause of my memory leak.
Thanks in advance for any suggestions.
