My application runs fine on any Google device. But when I try to run on a Kindle fire, it crashes. Right before the crash happens, Activity Monitor Logs show that around 15-20 processes that start with com.amazon die and are scheduled to restart. Then My app (which is running in the foreground) crashes and attempts to restart:

There is no description of the crash itself, so I'm not sure how to fix. Does anyone have any ideas?

    Does a trivially simple app get killed as well? If not, split the difference in complexity between your app and a trivial example, repeatedly, until you figure out the cause. – Chris Stratton Apr 25 '14 at 16:15

It may be an ANR.

I have a suite of about 400 unit tests that run fine on various other devices (including the Amazon Phone Fire) but fail on the Amazon Kindle Fire HDX 7".

When this "crash" happens there is no java stack trace and no c stack trace. The crash never happens on the same test. And, obviously, running those unit tests by themselves never causes an issue.

When the process finally exits, there isn't much fanfare beyond the normal unit test exist. E.g. there is a WIN DEATH log line, however even when the unit tests run successfully to completion it still announces WIN DEATH.

I have noticed something interesting though. When I monitor logcat using the following command:

adb logcat WindowState:I *:S

I see a page full of these:

I/WindowState(  826): WIN DEATH: Window{41968490 u0 com.amazon.kindle.otter/com.amazon.kindle.otter.Launcher}

When I sit there and watch the output, the pace of errors increases until my test app crashes.

According to some docs I've found, lack of response to a touch event in 5 sec, or a BroadcastReceiver running for 10 sec will cause an ANR in normal android. However, I don't know what amazon has done to it.

I did another test that passes a runnable to $getInstrumentation().runOnMainSync()$ which busy waits in an empty while loop for 120 seconds. That alone didn't cause the app to be killed, until I touched the back button. Then I see the same exact crash: window death, no stack trace, no c stack trace.

Also, in both the original crash and the deliberate ANR, I see a line mentioning ActivityRecord having difficulty (not always exactly this line):

W/ActivityManager(  826): Activity pause timeout for ActivityRecord{40fadb78 u0 com.amazon.kindle.otter/.Launcher}

I tried making the junit thread sleep for 1500ms after each thread, thinking that I was starving some background system of the UI thread (my unit tests cause 6,000 views to be created in a short amount of time), but that has not helped, and it has not noticeably delayed the crash either.
