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

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 ...

In old version, I read that it is a signature-protected permission, i.e. only apps that got signed as system apps are allowed to.

What is involved in getting app signed as system app? what if device is rooted? Thanks – Androider Apr 19 '11 at 02:42
this can be answered as on separate question here: – Androider Apr 19 '11 at 02:48
old version means 2.1 or pre 2.1? – Androider Apr 19 '11 at 02:53
Also are there other ways to put device in sleep mode programatically? Like issuing an intent? Thanks – Androider Apr 19 '11 at 02:56

java -jar signapk.jar platform.x509.pem platform.pk8 bin/TestApp-unsigned.apk bin/TestApp.apk

I had the exact same problem and this worked for me. Get signapk.jar from https://github.com/appium/sign. the repository also includes the Android test certificate, which works e.g. with a rooted nook.
