*** ** * ** *** Allows applications to enable/disable Bluetooth profiles on the system. Usage of this API triggers a restart of the Bluetooth stack, and the changes take effect only after all the Bluetooth services have been restarted. Usage: ``` BluetoothProfileManager profileManager = BluetoothProfileManager.getInstance(); List enabledProfiles = profileManager.getEnabledProfiles(); String enabled = ""; for (Integer profile : enabledProfiles) { enabled += ("" + profile + ", "); } Log.d(TAG, "Enabled Profiles - " + enabled); Log.d(TAG, "Enabling A2dp source mode."); List toEnable = Arrays.asList(BluetoothProfile.A2DP); List toDisable = Arrays.asList(BluetoothProfile.A2DP_SINK, BluetoothProfile.AVRCP_CONTROLLER); profileManager.enableAndDisableProfiles(toEnable, toDisable); ``` Certain configurations of profiles are invalid and behave differently. - [A2DP](https://developer.android.com/reference/com/google/android/things/bluetooth/BluetoothProfile#A2DP)and[A2DP_SINK](https://developer.android.com/reference/com/google/android/things/bluetooth/BluetoothProfile#A2DP_SINK)profiles cannot be enabled together. Doing so will throw an[IllegalArgumentException](https://developer.android.com/reference/java/lang/IllegalArgumentException.html). - [GATT](https://developer.android.com/reference/com/google/android/things/bluetooth/BluetoothProfile#GATT)profile cannot be disabled. It is active if Bluetooth is ON. - [GATT_SERVER](https://developer.android.com/reference/com/google/android/things/bluetooth/BluetoothProfile#GATT_SERVER)profile cannot be controlled using these APIs. Using them will have no effect. It is always active in conjunction with[GATT](https://developer.android.com/reference/com/google/android/things/bluetooth/BluetoothProfile#GATT).
