Hide createRfcommSocket(int channel)
Add createRfcommSocketWithServiceRecord(UUID uuid)
Rename listenUsingRfcomm(String,UUID) -> listenUsingRfcommWithServiceRecord(..)
Now we have a complete API for developers to make peer-peer RFCOMM connections
with hard-coding the limited (30) RFCOMM channels, instead using SDP lookup
of an UUID.
This commit addresses two serious bugs:
- Do not throw IOException on accepting an incoming RFCOMM connection with
BluetoothSocket. This was a regression from commit 24bb9b8af4ff6915
- Workaround failure of bluez to update SDP cache when channel changes by
trying to use the same RFCOMM channel on the server every time, instead
of picking server channels randomly. This is a pretty ugly workaround,
and we are still trying to fix the caching issue - but with this
workaround we are at least shippable and apps will work at least until
they start colliding on the 30 RFCOMM channels.

Hide listenUsingRfcommOn(int channel)
Add listenUsingRfcomm(String name, ParcelUuid uuid)
The new API automatically finds a free RFCOMM channel and registers an SDP
record with the given uuid and name. The SDP record is automatically
removed when the socket is closed, or if the application dies.
Apps are prevented from registering SDP records with the uuid of system
Bluetooth profiles, such as A2DP, HFP and OPP.
Apps are prevented from removing SDP records that they did not create. This is
tracked by pid.
TODO: Provide an API for the connecting app to look up an SDP record.

This happens when the the remote headset is in a bad state or is
not accepting connections. Try twice before giving up.

Adds a mechanism to tell Paint the scaling factor its target
canvas will have, for it to compute font metrics based on the
correct font size. Only TextView uses this, but that is enough
for the large majority of apps.

The problem is we missed an "obj" parameter while calling
postEventFromNative (which put it in a field of a Message object),
so a garbage value on stack is used.
When the GC tries to follow that "obj" field, expecting to find
another object, it crashes.
This call has been synchronus since Bluez3.36.
However, since the semantics for all Bluetooth API calls are
asynchronous make this so too. It does fix an occasional ANR
seen while unpairing.

Add new API which clients can use to force an SDP query.
The result is broadcast using an intent having the UUIDs.
The intent is broadcast after a timeout, in case of an error.
This timeout is greater than the page timeout.

1) Handle incoming 2.1 pairing requests
2) Modify displaying error messages on bond failures.
3) Add delay while accepting incoming pairing for certain 2.1 devices.
When MITM is on, the link key request might come more than once.
Auto accept with a delay.
4) Handle DisplayPasskey callback for pairing a 2.1 keyboard with
a 2.1 device
Remove the stuff that doesn't use preloaded drawables when in
compatibility mode, since this works fine ever since we were able
to deal with drawables in a different density than the canvas.
Change the snapshot function on View to return a snapshot at
the same size that will actually be drawn on screen (when in
compatibility mode), to be able to show scaling artifacts and
all.
This change was original an attempt to fix issue #2101917: Text
field edges appears to be improperly rounded. That turns out to
probably be something deeper in the graphics system, but also
included here is the debugging code I did to try to track down the
problem to make it easy to turn on again later.

Add a parameter to ToneGenerator.startTone() allowing the caller to specify the tone duration. This is used by the phone application to have a precise control on the DTMF tone duration which was not possible with the use of delayed messaged.
Also modified AudioFlinger output threads so that 0s are written to the audio output stream when no more tracks are ready to mix instead of just sleeping. This avoids an issue where the end of a previous DTMF tone could stay in audio hardware buffers and be played just before the beginning of the next DTMF tone.
ViewRoot was using Surface.clear(), which has different behavior
in different processes -- in the system process it would kill the
surface, causing all windows in that process to immediately disappear
instead of animating away.
This change makes Surface.release() public and uses that instead. It
also renames Surface.clear() to Surface.destroy().
Also fixed some issues in the window manager that were causing the
wallpaper to not get immediately resized when the orientation changes
and its target window is removed and re-added.

Unfortunatley, shutdown() on the underlying fd does not actually stop a
listening socket from listening. You need to call close() on the fd to
do this. There is no way around it.
So this means the Java BluetoothSocket code has to call destroyNative() during
BluetoothSocket.close().
Since native methods cannot be called after destroyNative(), add a ReadWrite
lock and mClosed field to protect access to native methods.
This fixes the "resource busy" error when Bluetooth OPP and Bluetooth PBAP
tried to resume listening after turning BT off and then on.
Some of this is temporary (in particular the two approaches for getting
process memory, one working but horrible, the other not working but
preferred) until I figure out the best way to do it.

Previously we had been setting the imageSize parameter to 0, which was
incorrect. According to the OpenGL ES spec for glCompressedTexImage2D
this parameter should be the size in bytes of the compressed data.
With a 64 KB OBEX MTU, net/rfcomm/sock.c:rfcomm_sock_sendmsg() quietly drops data.
The default SO_SNDBUF is 24 KB. Empircally, 36 KB still drops, and 38 KB no longer drops (this is because SO_SNDBUF is doubled in net/core/sock.c and then there is OBEX/RFCOMM overhead). Set to 70 KB so we have plenty of room to spare.
See http://b/2090000 to investigate this in more detail later.
We were running out of local refs when there are lots of devices.
Instead of deleting every single local ref, create a local stack frame.
This operation is inexpensive so doesn't add a high overload and keeps
the code clean instead of deleting every single local ref.
Split BluetoothDevice into BluetoothDevice and BluetoothAdapter.
BluetoothAdapter: Represents the local BT adapter. Operations on the local
adapter (start a scan, etc).
BluetoothDevice: Represents a remote BT device. Operations on remote devices
(pair, connect, etc).
IBluetoothDevice.aidl -> Bluetooth.aidl
BluetoothDeviceService.java -> BluetoothDeviceService.java
