  drawables to the sw720p-mdpi drawables, which look correct in the status

Fix unexpected rotation change when re-enabling auto-rotate

getProposedRotation() method returns old value when re-enabling
auto-rotate option. So you can see unexpected rotation change
with the following steps.

settings -> display -> enable auto-rotate
-> rotate device to landscape -> disable auto-rotate
-> rotate device to portrait -> enable auto-rotate

This patch makes mSensorEventListener reset before it is registered again.

Change default intent

Older JB releases have a bug handling persistence invocation. One work
around right now is to have the newer release (with persistence)
use  a lower intent value to allow older release to operate in group
owner mode.

Function uri.getAuthority is called twice. Minor doc corrections.

Function uri.getAuthority was called twice in methods acquireProvider
and acquireExistingProvider was called twice although a parameter
representing the value had existed. The second call to the function is
changed to the parameter. The parameter's modifier changed to final.
Minor corrections in function descriptions in the file.
