android - How to disable animations in code when running Espresso tests -


has managed disable animations through code when running espresso tests? i've been trying follow instructions in webpage (linked here):
https://code.google.com/p/android-test-kit/wiki/disablinganimations

unfortunately not appear working, keep seeing permissions error:

04-27 15:48:28.694      303-342/system_process w/packagemanager﹕ not granting permission android.permission.set_animation_scale package com.cookbrite.dev (protectionlevel=50 flags=0x18be46) 

i hoping avoid reconfiguring device/emulators. run individual tests locally , annoy me if have keep toggling settings.

i noticed other developers complaining doesn't work, might not alone:

i got work. here gist listing required steps:

the key step had missed running adb grant permission:

adb shell pm grant com.mypackage android.permission.set_animation_scale     

adding permission manifest , running reflection steps did not seem enough on own.
