[zipcom500]

when I finish phone call, can't restart recording.

when incoming call

1. the app will receive message "AUDIOFOCUS_LOSS_TRANSIENT" , then turn off recording. It work well.
2. when pick up the call, then hang up, the app will receive message "AUDIOFOCUS_GAIN" , then I want to restart recording, but will be failed. Here is the error message:
   E/IAudioFlinger: createRecord returned error -1
   E/AudioRecord: createRecord_l(0): AudioFlinger could not create record track, status: -1
   But the permission "android.permission.RECORD_AUDIO" had been allowed.
