Android What permissions required to call PowerManager.goToSleep(n) put device in sleep mode?

Question

Already set android.permissions.DEVICE_POWER in manifest of my app. Still complains that neither user nor process have this permission when I call PowerManager.gotoSleep(n) within activity. What other settings are required for this to work? Thanks This is on My Samsung ATT phone

Answer 1

DEVICE_POWER is a level 2 permission and protected permission and hence it is not provided to any app which request it via manifest, to get this permission successfully we need to have Platform certificate in our make file and shared user id set in manifest as system...

LOCAL_CERTIFICATE := platform (makefile entry)

android.uid.system (shared  user id )

There isnt a way around this i have looked around havent found any ...
