This is the framework part, moving classes around so the framework
no longer needs to link to android-common. Makes some APIs public,
others that didn't need to be public are private in the framework,
some small things are copied.
queryBroadcastReceivers() can return null, so AppWidgetService
should guard against that.
Fixes http://b/issue?id=2418982
Change-Id: I1ba83c0c37622e0280f3dba2fef5eca2cc90c975
Add new broadcasts ACTION_MEDIA_RESOURCES_AVAILABLE and
ACTION_MEDIA_RESOURCES_UNAVAILABLE that get broadcast by
PackageManagerService when sdcard gets mounted/unmounted
by MountService so that packages on sdcard get recognized by
various system services as being installed/available or
removed/unavailable by the system.
The broadcasts are sent before the actual package cleanup which includes
mounting/unmounting the packages and we force a gc right after so
that any lingering file references to resources on sdcard get
released.
If not these system services will end up with inconsistent settings files
when the device runs out of storage.
Delete mangled settings file in PackageManager if the current write fails
so that we don't end up overwriting the backed up version with the
mangled version
Include null check when retrieving fwd locked resource for an existing package
There are three major classes of changes here:
- Avoid writing lines where their values are often empty, false, or some other typical thing.
- Use partial writes to the PrintWriter to avoid creating temporary strings.
- Use StringBuilder where we need to generate real String objects (and where possible cache the result).
