Hi all,
I am trying to implement Serial and Hid profile API in android framwork.
Getting IBinder value Null while init to Serial profile or Hid profile using
settings menu-->

Same Code present

public BluetoothA2dp(Context c) {

IBinder b =

IBluetoothHid.aidl ------------------->
/**
* System private API for Bluetooth HID service
*/
interface IBluetoothHid {
int connectDevice(in String address);
int disconnectDevice(in String address);
List<String> listConnectedDevices();
int getDeviceState(in String address);
int setPriority(in String address, int priority);
int getPriority(in String address);
}
Anybody has idea for this IBinder return value differ in A2DP and Serial or
HID profile ?
Any help will be highly appreciated.
Thanks & Regards,
Deepak
