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)
Under a pseudo-app for the Package Manager, we store the app signatures for all
participating applications installed on the device. At restore time we will
restore this first, then ensure that the current on-device signature chain is
compatible with the one in the backup set. If there's a mismatch, this may be a
spoof attempt and we will refuse to restore that app's data.
The restore side of this is not implemented, but the Package Manager agent is
here as well as the backup side theoretically pushing the data now.
In eventLoopMain we were correctly translating from unix events to dbus flags,
but a coding typo then gave the unix events to dbus. Fix this typo.
Also noticed that we were passing raw dbus flags to poll() in another area.
This did not cause any immediate problem, since POLLIN | POLLPRI is harmless
and we do not usually need POLLOUT. But fixed anyway.
ro.sf.lcd_density is usually defined in the build.prop file which is parsed by init
before anything else. Since its name begins with "ro.", this property is write-once
and cannot later be modified, e.g. in /system/etc/init.goldfish.sh.
In other words, you cannot use "emulator -prop ro.sf.lcd_density=<value>", since
it is impossible to override the value defined in build.prop
This patch modifies the system to recognize "qemu.sf.lcd_density" as an override
value, which can be set with "emulator -prop qemu.sf.lcd_density=<value>", forcing
a specific density.
A later patch will allow the emulator to automatically set this property depending
on AVD hardware configuration settings.
The Resources class keeps a cache of known resources. The keys used by the
cache are stored as int primitives. For any given drawable resource, a key
is built thusly:
TypeValue.assetCookie << 24 | TypedValue.data
In the case of a plain color drawable, assetCookie always equals -1, that
is 0xFF once right-shifted and the data contains the color value. Which
means the key for the following two colors is the same:
0xFF000000
0x00000000
Because of the int storage and the use of the (constant in this case)
asset cookie, the alpha channel of a color is ignored. That means that
if you first load an opaque black color (0xFF000000), subsequent loads
of a totally transparent black color (0x00000000) will give you an
opaque black color.
A workaround is to use a transparent color that is not black,
0x00000001 for instance. Note that this issue would arise with any color
and any opacity level.
The solution to fix this issue is simply to change the cache to use
longs instead of ints to represent the keys. A key thus becomes:
TypedValue.assetCookie << 32 | TypedValue.data
This allows us correct storage of all colors at the cost of a few bytes.
The tradeoff is that we can keep caching ColorDrawable, which is
definitely worth it.
* changes:
Grouping under TextToSpeech.Engine the constants to be used by a TTS engine implementation or a settings application for default values, and data integrity check return codes.
Basically this does automatically what the developer has to do in his/her
activity so that the TabHost gets tabs that connects the TabWidgets and the
content of the FrameLayout.
