broadcastreceiver

Can an ios app (possibly not active) be notified if there is a change in wifi network connected to(getting disconnected from, or getting connected to new ntwk)? I am to build an app that (even in inactive state) should get notified when connected to a particular wifi network and do some stuff. In android i was able to achieve it using BroadcastReceiver is there any such facility in ios? Thanks, Praneeth. Rajan Maheshwari We have a class called Reachability in iOS for detecting any network flicker/disconnection/connection. Reachability class can be found here Usage Add Reachability.swift class

This question brought up an interesting issue. The OP has an app that displays a map, and this map needs to be updated with location markers that are received via SMS messages. The individual steps are fairly straightforward: the SMS messages can be received by a BroadcastReceiver , the markers can be displayed by an ItemizedOverlay on top of a MapView . The tricky part is to have the receiving part communicate with the main part of the app. What happens if the app has an active MapActivity , and then its BroadcastReceiver is invoked as a response to an incoming SMS? Is the MapActivity

I have a progamm with async task and a broadcast receiver to send a result code, so that Asynctask will know that app is working. But it crashes, sayin the receiver is unreggistred in main activity. I've registred one receiver in main activity, another receiver is in AsyncTask Activity. So here the code and log cat. @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mFragmentManager = getFragmentManager(); addFriendsFragment(); // The feed is fresh if it was downloaded less than 2 minutes ago mIsFresh =

Is there any way how to get a reference for a BroadcastReceiver defined in Manifest.xml from code? In my case, we are using a BroadcastReceiver that needs to be included in the Manifest.xml. However it has functionality I would like to reuse from within our code. So instead of creating another similar BroadcastReceiver and instantiating it from the code I would like to obtain a reference to the existing one. Additional information: My goal is to subscribe to an event on my BroadcastReceiver from my activity - an event that I would like to reuse - instead of creating another instance of this

I have a strange problem. To detect outgoing calls I have registered a broadcast receiver for android.intent.action.PHONE_STATE . When the state becomes OFFHOOK, then a conversation is started. It seems working on emulator: the debugger in fact reaches some code while it doesn't work on real device (Acer Liquid). Is it possible? Which is a way to detect outgoing calls? Well, if it works on the emulator, I would expect it to work on the device. You might registering a PhoneStateListener with the TelephonyManager via listen() and see if it gets you better results. If you think of it, comment on

What is the best way to pass simple data such as a String between applications? The String is some field that is known in the sender app and is needed by the receiver app. I looked into storing it in a MODE_WORLD_READABLE SharedPreferences, but I won't necessarily know the package name (this would exist in a library), the value can be set by various apps, so it'd be difficult to look up. I was thinking have both apps contain BroadcastReceivers. When the receiver app is opened, it sends a custom Intent for the sender app to receive to tell it that it's ready to receive. Upon seeing that Intent,
