We now record the version number of the app (drawn from its manifest versionCode
attribute) along with its signatures. At restore time, we compare the version
associated with the restore set with the version present on the device. If the
restore set is from a newer version of the app than is present on device, we do
not perform the restore operation.
Also fix the pending-backup iteration in 'dumpsys backup'.
The aapt tool now reports all available densities like it already did
for locales. Also this includes more resource data output, which I
was using to examine bug #1867049 (which at this point I am unable to
reproduce).
* changes:
when we reset a paint, it should return to the state it was in when it was first created. for java, this means setting its text-encoding to UTF16...
The GPS engine needs the hostname for the secure SUPL case
and deferring the DNS lookup to the HAL might be helpful in the future
if the SUPL server is on a carrier's private network.

The check for allowing the start of an activity was broken, it was
comparing the process of that activity's application vs. the current
instrumentation target package name. Okay it was utterly insane.
Now this check is that the target activity will be running in the
same process as the instrumentation, which is really what we want.
This is a monotonically increasing integer. Wraps to 0 at
Integer.MAX_INT, and at boot.
Current implementation returns the number of AT commands handled since
boot. This is a good indicator for spammy headset/handsfree units that
can keep the device awake by polling for cellular status updates. As a
rule of thumb, each AT command prevents the CPU from sleeping for 500 ms
On restore now, the backup manager gets the signature blocks corresponding to
the restore set from the transport. It then validates those signatures against
the on-device app signatures, and refuses to restore data to an app whose
on-device sig block does not match the backup image's.
Also actually implement 'bmgr transport N' so that we can select the local
transport easily during runtime.
Eat the security exception that is now thrown by the window manager to
retain the old behavior for tests. (We still need to throw the
exception from the WM for the new permission tests.)
- Fix a bug where targetSdkVersion could not be set if minSdkVersion. Stupid, stupid.
Also make sure to fail if minSdkVersion is for a code name. Really stupid.
- Change the API for resize compatibility mode to be a bit in the flags field, instead
of a separate boolean.
- Implement delayed dexopting, to avoid the looong full dexopt during boot. This is
only enabled for "eng" builds. When in this mode, the activity manager will make
sure that a dexopt has been done before loading an .apk into a process, and will
try to avoid displaying ANRs if they are due to the dexopt causing some operation
to take longer than it normally would (though I make no guarantees about this
totally working).
- Add API to Context to get the ApplicationInfo for its package, for easy access to
things like targetSdkVersion.
* changes:
Update RandomBlock to use RandomAccessFile. This helps prevent certain unusual conditions from corrupting the entropy file. (for example, if Android should happen to crash while a write is in progress)
