Bug 748350 is for sharing files between PC and device via MTP protocol.
The benefit is that

  1. MTP didn't need to unmount storage first then share to PC, so device side can use that storage while MTP is working.

  2. MTP hides the file system type on storage so device can share file with Windows OS even later didn't support ext4.

  3. MTP didn't limited the transfer layer and it can be USB, TCP/IP or others. Currently USB will be high priority.

Bug 932701 -

Refer to Bug 924383.

The audio playback is a key application on mobile platform so how to guarantee it's performance is important to satisfy user experience. 

Current Situation:

Currently the nice & priority of threads in the background will be set to lower then foreground app. And background app playing audio will be set between foreground & background app.

The problem is

  When foreground is busy, the music player in the background is easy to be noticed about underrun issue.

The rough idea

  ProcessPriorityManager will keep threads related to media playback to equal or higher then foreground app no matter they are in the background or foreground.

Bug 871467 - [AudioChannel] To generate alert tone during in_call state when alarm/notification is fired.

Current Situation:

The alarm didn't fire any sound to notify user during voice_call state so user didn't have a chance to know this alarm.

Rough idea:

AudioChannelService can report what channels are used and their status now.
Then system app can base on these information to fire a "do do do" tone on telephony channel instead of original alarm tone on alarm channel.

   Depend on compressed size of I-Frames to select a big I-Frame as thumbnail.
