ANT+ error on Sony phones and ANT Radio Service v3.4

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use a Sony Xperia phone, update ANT Radio Service to current v3.4
2. Turn Bluetooth off
3. Start MyTracks and try connecting to ANT+ sensor

What is the expected output? What do you see instead?
I expect to see Sensor State 'Sending' in MyTracks, and the ANT+ icon in the 
system bar. Instead I see 'Disconnected'.
On occations I get a connection. Turning BT on helps.

What version of MyTracks are you using? On what version of Android? On what
phone?
MyTracks 2.0.4
Android 2.3.4
Sony Xperia Active

Please provide any additional information here:

The ANT Radio Service release note states that with the update, Sony phones 
'may take time to re-enable on app-start'.

SOLUTION:
Change AntSensorManager.java such that openChannel and requestReset are called 
in statusReceiver when the ANT_ENABLED_ACTION  message is received.

I have been able to reproduce this using MyTracks 2.0.4, Android 2.3.4 and with 
the most recent released ANT Radio Service v4.0.0 on a Sony Xperia Ray.

I can work on this in the upcoming weeks.

We have seen this issue with other apps using ANT and will be fixed in the next 
release of ANT Radio Service. No change to MyTracks will be required.

This is no longer an issue with the recent release of the ANT Radio Service 
version 4.1.0 which contains a fix for the cause of this bug. No change to 
mytracks is needed; just update to the newest ANT Radio Service version and 
this will eliminate the problem/error connecting to ANT+ sensors!

Have you tested this on your Xperia Ray? On my Xperia Active, with ANT Radio 
Service version 4.1.0, I have still no luck. Although I was able to connect a 
sensor, after stopping and restarting MyTracks it won't connect again. On my S3 
with ANT+-USB-dongle, I get no problems.

The only difficulty I am seeing is if you start recording and immediately go to 
the sensor state activity then the state seems to get stuck in 'Connecting' 
with the logs reporting that the sensor data set being null. This happens the 
first time you start mytracks too; no need to stop/restart. Is this the 
behaviour you are seeing? This might be a separate issue than having 
difficulties connecting with BT off.

Good news is that the difficulty connecting to ANT+ sensors with BT off is gone 
having tested this on my Xperia Ray. Can you confirm this as well?

Unfortunately, no. Just checking again on the Xperia Active: with BT off, no 
connection at all. With BT on, starting recording most of the times shows the 
ANT icon in the status bar, and sensor state activity shows sensor data. In one 
occasion, ANT+ would not start without stopping and starting the recording.

MyTracks must wait for ANT to be enabled before trying to use it (as the 
original posted solution proposes).
This would always have been an issue (not just since ANT Radio Service 3.4), 
but is more noticeable now that the ANT Radio Service does not run forever, 
requiring ANT to be enabled each time it is started.  Some devices do not 
(usually) see an issue simply because they enable quickly enough that no ANT 
requests occur before the enable is complete.
