Can't get my head around it I tried following the steps for replacing the code to use android.hardware.usb instead but I still get an issue with their own android developer routine //mManager = UsbManager.getInstance(context); UsbManager mManager = (UsbManager) getSystemService(Context.USB_SERVICE); however now it doesn't recognize getSystemService Here's where it fails. public void setup(Context context) { //mManager = UsbManager.getInstance(context); UsbManager mManager = (UsbManager) getSystemService(Context.USB_SERVICE); //<----- UsbAccessory[] accessoryList = mManager.getAccessoryList(); PendingIntent mPermissionIntent = PendingIntent.getBroadcast(context, 0, new Intent(ACTION_USB_PERMISSION), 0); IntentFilter filter = new IntentFilter(ACTION_USB_PERMISSION); context.registerReceiver(mUsbReceiver, filter); mManager.requestPermission(accessoryList[0], mPermissionIntent); if (accessoryList[0] != null) { mAccessory = accessoryList[0]; if(mManager.hasPermission(mAccessory)) { openAccessory(mAccessory); } } } android adk mbed share|improve this question edited Mar 30 '14 at 23:49 asked Mar 30 '14 at 20:01 Iancovici 50311034 2 Search developer.android.com/guide/topics/connectivity/usb/… for the add-on symbols and you will find their replac

between MBED - Android device Jellyeban 4.1.1 Is it possible to use the AndroidAccessory library to set up a USB communication between MBED - Android device Jellyeban 4.1.1 Topic last updated 24 Nov 2013, by David Lam. 1 reply R A raalst1 # 25 Jun 2013 Dear All, We use the AndroidAccessory Library [1] to setup a USB communication between MBED and an Android device In our case the Android device is an Android TV stick, to be precise a Tronsmart MK808b with Android Jellybean 4.1.1 installed [2]. However, setting up the USB communication with Androids ADK gives some problems. When I want to build it and run it at the Android stick I get the following error message in the Android Development Tool (ADT) using the Android Debugging Bridge (ADB): "Package com.test.demo requires unavailable shared library com.android.future.usb.accessory; failing!" I don't get this message when I have connected a normal Samsung Galaxy S2 smartphone (Jellybean 4.1.2) instead of this Android TV Stick. So I have the following questions for setting up the USB communication between the Android TV Stick and the MBED side: (A) For the smartphone tested App - MBED USB communication, with use of the ADK, the App uses the 'com.android.future.usb.accessory' library. However, these USB accessories APIs are a Google APIs add-on library to backport it to models before Android 3.1, using an external library, namely the 'com.android.future.usb.accessory' library [3]. Has somebody managed to setup an Android - MBED USB communication using the built-in library (after Android 3.1), so the 'android.hardware.usb' library in combination with the MBED AndriodAccessory Library [1]? Is there a MBED library available with examples of this? (B) Does somebody know how to check if the library 'com.android.future.usb.accessory' is available on the Android O
