[android] AudioFlinger cannot acquire wakelock from powermanager service

[Ricardo Salveti]

Powermanager is a JAVA based service at Android, which is responsible for exporting the acquire/release methods for general usage at the Android Platform code.

AudioFlinger needs to acquire a wakelock in order to be able to play a sound when it receives a notification and the device is suspended, otherwise the sound may not play or get interrupted during playback.

As in our case we're not yet supporting audio notifications when the device is suspended, this is not critical, but something will probably need to be supported at some point.

And due the service being exported as JAVA, we'd need to implement this acquire/release wakelocks methods via another service, which will probably be used for general power management at the device.

The log which presents this error:
W/AudioFlinger( 165): Thread AudioOut_2 cannot connect to the power manager service

This bug is being reported based on code inspection, not direct testing. It should be reproducible on the Nexus4 which actually goes into full suspend.

I'm updating the Status to FixReleased, as I can't reproduce this behavior with phablet-image #76 ( plus updated qtubuntu ).

I caused the indicator go blue by sending text messages, and after each was received, pulled down the messaging indicator and tapped the "clear all" button. I repeated 10 times and for each, the messaging indicator had correctly reset to a white icon.

Actually I made a mistake and marked the wrong bug FixReleased. I'm resetting the Status back to New so that someone can confirm.

@Ricardo

Does this occur on all devices? I couldn't reproduce on a Nexus Galaxy, probably because it doesn't fully go into S3. Was this on the Nexus4 only?

as now it switch to pulseaudio and not using audiofliger, the wrong behaviours (press power button to suspend device will stop music playback) still exists.
