Does android 5.0 support HFP client (act as Headfree client devices by Bluetooth)??

+3 votes

I found a config value in packages/app/Bluetooth/res/values/config.xml and a hide class

  • false
  • android.bluetooth.BluetoothHeadsetClient, this provides HFP client API, such as dial, accept call.

I set profile_supported_hfpclient to true, and remake and flash the system. I write a test app to using BluetoothHeadsetClient API, and it can dial and accept call. However, the voice is not working when calling. The speaker doesn't make sound, and the voice received by mic isn't transferred by Bluetooth SCO.

So does android support HFP client fully? How can I make voice works well

In Android5.0, an App(apk) can be installed in multiple users. When the App is running in another user, there is a new process of the App. I want to develop a App which is running in multiple users but only one process is created. Some system process, such like "" is running in this way. But I can not find the way to do that.

I have tried as below, but don't work.

  1. use sharedUserId as system, and mark persistent to be true;
  2. sign app as platform signature, put the apk to /system/app or /system/priv-app/;

However, service/recevier/provider can use in manifest.xml to share the same component although.(single user tag must be installed in /system/priv-app/).
