On factory reset, we need to restore audo path related settings and hence
create an API for that.

If BT is connected after FM app launch and then FM is turned off and then
turned on, audio gets routed to wired headset. Check if A2DP device is
connected every time FM is turned on. Also set the UI icon to correct
image.

Whether a2dp is disconnected or not,
fm should pause when fm service receives
intent "com.android.music.musicservicecommand".

A configuration change (such as a change in screen orientation,
language, input devices, etc) causes current activity to be
destroyed, going through the activity lifecycle process of
onPause(), onStop(), and onDestroy() as appropriate. If the
activity had been in the foreground or visible to the user,
once onDestroy() is called in that instance then a new instance
of the activity will be created.
Change will ensure that activity doesn't get restarted on
orientation configuration changes.

On receiving media pause command, we stop FM operations(disable audio etc.).
We lost audio focus but we don't configure StoppedOnFocusLoss variable to true.
When Activity restarts, we never lost audio focus as per this variable.
Hence no audio heard on FM resume.

Change-Id: I94ef44c6ec18b2ef9fe03a7519979b1e55f61e99

Stop FM operations (disable audio, update UI etc) after
FM has been stopped. When FM is muted and FM stops,
short audio has been redirected to audio device before
FM stops, that shouldn't be redirected.

Change-Id: Id9cf5bedd753b79992b6f42e7a5668ad2561c6d1

When FM is turned off, fm app is still listening to media key events
(play, pause etc.) which results in other media consuming apps to be
starved of Media Key events.
Remove unwanted media button listeners so that other media resources
can receive key events.

Change-Id: Ib43f8b89e07928326c2af771a7465981e1690470

This include adding fmhal service for access RFKill driver
to do power ON/OFF operations during FM enable/disable.

Change-Id: I77c100533ca47bf0e53bccdbb1d93c08058df4bf

On FM close, we don't wait for tx and rx threads to complete and
returns. If we turns on FM again and threads terminated during that
interval causes ANR as we destroy mutex during thread tremination
and on FM ON we try to acquire the destroyed mutex.
On FM close, wait for threads to be terminated and do the cleanup.

Add support for FMStats app for cherokee platform.

This does enable ECC bit during RDS group processing and add
logic to receive ECC events from SOC and sent the ECC code to
application.

Change-Id: I61687ea6fe041d2dc4aed16700632be5cdd781d8

This ensures FM application works across all chipsets

Change-Id: Ia9711fd18c79146678a72992b32a577e73c57693

Added HAL changes for hci commands like peek, poke, get/set of
SINR sample/threshold.Compile time changes for adding correct
includes based on new bluetooth stack structure, code cleanup
and indendation.

Change-Id: I5e48f0c0dc6165d61335c6d8cc269891e26dd548

This provide hardware error event to FM module during SOC
failure and resets FM gracefully.

Change-Id: Ic4345e02c8a1cba218414afdfcf3e76734c314b0

This include adding support to read RDS group counters and
other diagnoistic hci commands used  for FTM app.

Change-Id: I56656dc9d427a32f0385f586535d3421ff4f49b0

This adds configuring RDS group processing for RT+ and ECC events,
Also includes code cleanup and changes to set proper value for RDS
group processing registers during SCREEN turn on after LOW Power
mode.

FM Serial interface provides APIs for FM HAL layer to send cmds
and receive events/data to and from the Controller.

Change-Id: Idbe21e536a6039387c7411b8a9322417e4ec6129

FM-HAL Layer contains the core FM Functionality required
for carrying out various FM operations such as FM Enable,
FM Tune, FM Seek, FM Search, FM Disable etc..
FM-HAL layer interacts with the FM-HCI layer for sending
commands and receiving events to and from Controller.

Remove FM transmitter functionality to fix build error.
FMTransmitterActivity.java and FMTransmitterService.java are removed
from Android.mk for Android N platform bringup. These two files can
be added whenever transmitter functionality shall be required.
