Установите BluetoothController в качестве приложения в вашем AndroidManifest.xml

<application 
    android:icon="@drawable/ic_launcher" 
    android:name=".BluetoothController"  <-- Here is the change 
    android:label="@string/app_name" 
    android:logo="@drawable/ic_launcher" 
    android:theme="@android:style/Theme.Holo.Light" >
