android - Failing to establish a connection with a custom service -


i own lilypad simblee ble board - rfd77101, i'm trying establish connection custom service defining in arduino 1.6.5 ide simblee.customuuid command.

i later tried service , characteristic in android studio bluetoothlegatt sample code using uuid established previously.

the problem when connect simblee app fails recognize service , logs me following error.

custom ble service not found

the code kinda long hence not posting of directly. if has idea solution problem , need , part of code more glad post it.

thanks in advance.

this public void attempt obtain characteristic:

public void readcustomcharacteristic() {   if (mbluetoothadapter == null || mbluetoothgatt == null) {     log.w(tag, "bluetoothadapter not initialized");     return;   }   /*check if service available on device*/   bluetoothgattservice mcustomservice = mbluetoothgatt.getservice(uuid.fromstring("fe84-0000-1000-8000-00805f9b34fb"));   if(mcustomservice == null) {     log.w(tag, "custom ble service not found");     return;   }   /*get read characteristic service*/   bluetoothgattcharacteristic mreadcharacteristic = mcustomservice.getcharacteristic(uuid.fromstring("2d30c083-f39f-4ce6-923f-3484ea480596"));   if(!mbluetoothgatt.readcharacteristic(mreadcharacteristic)) {     log.w(tag, "failed read characteristic");   } } 

bluetoothgattservice mcustomservice = mbluetoothgatt.getservice(uuid.fromstring("fe84-0000-1000-8000-00805f9b34fb"));

the uuid provided not in correct format. according documentation, part before first hyphen should consist of 4 hex octets (see 1 provided characteristics) got 2 here. should add padding 0 in front like

bluetoothgattservice mcustomservice = mbluetoothgatt.getservice(uuid.fromstring("0000fe84-0000-1000-8000-00805f9b34fb"));

edit : missing point here. have called mbluetoothgatt.discoverservices()?

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
