ios - CoreBluetooth didDiscoverPeripheral not being called when phone is locked -


i have ios app (swift) reacts custom ble device. device sends message 5 seconds when being clicked. app scans service , not connect device. working fine when app in foreground or in background, not when phone being locked (power button pushed). worked fine before (before ios 10).

code snippets:

// init centralmanager centralmanager = cbcentralmanager(delegate: self, queue: dispatch_get_global_queue(qos_class_background, 0))  ...  // in centralmanagerdidupdatestate let arrayofservices: [cbuuid] = [cbuuid(string:"0000****-0000-1000-8000-0080********")] self.centralmanager?.scanforperipheralswithservices(arrayofservices, options: [cbcentralmanagerscanoptionallowduplicateskey: false])

i enabled background modes: uses bluetooth le accessories. , have bluetooth-central in .plist uibackgroundmodes.

i've read stackoverflow posts deal problems alike , tried if solutions worked me. haven't found useful regarding problem in apple documentation either. tried example:

  • cbcentralmanager queue nil / mainqueue

  • scanforperipheralswithservices(nil , , different options)

anyone know workaround problem can work used to? or know of change in ios 10 prevents working?

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
