ANR on NativeActivity sample App provided by Google on JB

[Maunik Shah]

HI Framework Developers,

I am having an ANR issue with an application built using NativeActivity. I could not get any clues based on traces. Further, the application was roughly deriived from the Sample NativeActivity application provided by Google. So I tried to build the sample NativeActivity app provided with android. [<platform_root>/development/ndk/platforms/android-9/samples/native-activity]
When I run monkey on that sample App on JB, it gives me ANR on that application within 10-20 seconds. where as I'm not seeing this issue on GB/ICS with the same App. The ANR traces shows main thread was waiting in looper and not doing any CPU intensive processing.

Monkey command: adb shell monkey -p com.example.native_activity -v -v -v --throttle 500 1000000

Here I'm attaching the log file and top logs

12-28 11:25:03.574   258   296 E ActivityManager: ANR in com.example.native_activity (com.example.native_activity/android.app.NativeActivity)

The main thread stack is like this at the time of  ANR:

  #09  pc 00066d4d  /system/lib/libdvm.so
  #10  pc 00027260  /system/lib/libdvm.so


I'm suspecting, there is something wrong in InputDispatcher.cpp as the reason behind this ANR is keyDispatchingTimedOut.

What would be the reason behind this ANR issue as it was not there on ICS & GB?

Thanks,
Maunik

Can you enable the Wifi and Run the Monkey Test?
