Internet in android application is not working in case of Bluetooth Tethering

Question

Internet in my Android Application is working in case of Wifi and Mobile Data. But when it comes to Bluetooth Tethering, its not working. What can be the possible reason/solution for that?

I have used the following permissions so far:-

<uses-permission android:name="android.permission.BLUETOOTH"/>
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>
   <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.GET_ACCOUNTS"/>
    <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE"/>
    <uses-permission android:name="com.android.bidloc.permission.C2D_MESSAGE"/>
    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>

Thanks in Advance.
