Android CTS is showing ShellCommandUnresponsiveException on emulator

Question

I am running Android CTS Android Test Plan on an emulator running on Android 2.2.

But most of the test cases are showing timeout and the error shows com.android.ddmlib.ShellCommandUnresponsiveException.

Is there any way to solve this issue ?

Answer 1

Set shell command time out to 5 minutes (instead of 5 seconds:-))

Answer 2

A bit more notes for newbies like me:

1. download android source
2. apply the patch, and build with command: make cts
3. copy the newly built file cts.jar to replace the stock one.

This fix CTS timeout problem because some adb commands needs more than 20 seconds to return on my MotoA953 device (one of these is am instrument -w -e bundle true android.tests.devicesetup/android.tests.getinfo.DeviceInfoInstrument).
