Does Android broadcast an intent when the network state has changend, i.e. from GSM to Wifi? And if so what permission do I need and what is the intent action called?

Am I right if I say that, there is no broadcast action currently for the SIM card state changes?
View 2 Replies View RelatedI was just working on an application that will do stuff when a call is missed or made; and am left wondering why do you have to register a listener using a long lived background service for phone state changes instead of being able to use broadcast intents?
View 2 Replies View RelatedIs there a Broadcast Intent that gets sent out when the device is plugged in for power? I want to create a BroadcastReceiver to detect the device's plugged in state.

View 2 Replies View RelatedIn the examples, they create Intent as:
Intent intent = new Intent(this, AlarmReceiver.class);
But suppose my AlarmReceiver class is in another app, how do I create this intent?
I've tried with

but nothing happens.. It was not called..

But ofcourse i need context..this won't work. How can i handle this.
I'm building a service that sends a broadcast intent when some value changes. The service sends the broadcast like this:
Intent broadcastIntent = new Intent(); broadcastIntent.setAction("nl.vu.contextframework.NEWREADING"); broadcastIntent.setData(Uri.parse("context://"+cer.getKey())); broadcastIntent.putExtra("reading",cer); broadcastIntent.addCategory("nl.vu.contextframework.CONTEXT"); sendBroadcast(broadcastIntent);
In some Activity (in a different process), I'm tryint to receive this broadcast as follows:
IntentFilter intentFilter = new IntentFilter();
intentFilter.addDataScheme("context");
intentFilter.addCategory(CATEGORY_CONTEXT);
registerReceiver(new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
Log.d(TAG,"Received intent "+intent); }
}, intentFilter);
I am new to android platform.please help me out how the Broadcast Receiver and Intent Filter behaves in android.please explain in simple line or with example.
View 1 Replies View RelatedI'm working on a project where I need to run the BroadcastReceiver for a third party library for a specific Intent. I also want to run some of my own code when the Intent is broadcast. If I supply my own BroadcastReceiver for the same Intent, it seems that only, one or the other runs, but not both, depending on which appears first in the AndroidManifest.xml file. Is it possible to register multiple BroadcastReceivers for the same Intent in the same application and have them all run? AndroidManifest.xml snippet

We have an Activity which has a form on it and we launch an Intent to take a picture.We've overridden onSaveInstanceState and onRestoreInstanceState to push the data from the view fields But, on the return from the CameraActivity, the onRestoreInstanceState method is never called. Should this behavior work when calling another Intent?

So when I currently use a broadcast receiver to listen for the state changes in Wifi, so when this recieves an intent I want to be able to send this info on to my service. Is this possible and if so the correct way to do it?
View 2 Replies View RelatedI have a main activity class that launches a couple of my subordinate activities from a tabHost.
Periodically (actually when I receive an incoming message on a socket), I want to inform the subordinate activities that application state has changed so that they can refresh their views.
In Swing I could wire this together using something like a PropertyChangeListener. As far as I can see, the Android design philosophy requires creating an Intent and broadcasting to (as far as I can tell all) other activities that are running.
This strikes me as overkill considering that I'm only trying to notify my own views of a model change. Am I missing something?
im currently looking for the way that my app knows when the phone has being paired and connected to a bluetooth headset device.
I read something about this intent, but not on the Reference documentation of http://developer.android.com
android.bluetooth.a2dp.intent.action.SINK_STATE_CHANGED
Is this actually working, is it officially supported.
I mean, can we just register a broadcastreceiver to handle this intent , check for the EXTRA_STATE string extra to see if it equals STATE_CONNECTED and be sure that the phone is now connected with a bluetooth headset device ?
What about this BluetoothA2dpService class? There is no official documentation about this, everything i found i from code snippets of the android OS source code.
I used to keep my SSID broadcast at home disable, and four computers have never had a problem using the network. Only my Incredible doesn't seem to be able to reconnect to a remembered network not broadcasting its SSID. In fact, if I turn off the SSID while the Incredible is connected, it instantly drops the WIFI connection. Anyone have luck having the Incredible use a network without the SSID being broadcast constantly? I'm using WPA2 if that makes a difference.

I added broadcast listener "BATTERY_CHANGED" to Android Manifest file so that when the status changed I should get informed. I am adding to Android Manifest file as I want it active through my application life time. But the problem is that I am not getting the broad cast event from the system when battery status changes.
My code is here :-
<receiver android:name=".MyBroadcastReceiver" android:enabled="true"
android:permission="android.permission.BROADCAST_STICKY">
<intent-filter>
<action android:name="android.intent.action.BATTERY_CHANGED" />
</intent-filter> </receiver>
<uses-permission android:name="android.permission.BATTERY_STATS"/>
<uses-permission android:name="android.permission.BROADCAST_STICKY"/>
I am new to android. I what to know the difference between Intent and Broadcast Receiver. I am more confused with Broadcast receiver then Intent. Simple codes will be helpful.

I have restarted the phone, pulled the battery,put my sim card in my brothers captivate and it works fine on his. After the phone restarts the 3G icon will appear for maybe 1 minute and I connect for that short time then it disappears and no more 3G. If I switch to wifi I can connect just fine.

I tried PhoneStateListener but not working.
I'm trying to figure out if a system event broadcast is broadcasted using ordered broadcast or normal.The event is EVENT_REMINDER and in the source for the calendarprovider i noticed it sets up a alarmmanager to sent the broadcast. I can't find how the alarmmanager sends it. My guess would be as a normal broadcast , But while i was trying some things i noticed i could delay the system's notification (tried up to 10 sec) by building a sleep in my broadcastreceiver. This would indicate that they are handled ordered , and the systems receiver is only called when mine has finished. But can i be sure of this behavour?? (in all 1.5> sdk versions) the docs state that in some cases normal broadcasts are also handled ordered..due to spare of resources.
View 1 Replies View RelatedI have a compound UI component built up from a ViewGroup containing a number of TextView, ImageView etc. components. Many of these have StateListDrawables as their images/backgrounds. Is there any way of making them select from this drawable based on the state of the parent ViewGroup rather than the component itself? Ideally I want to be able to change the visual state of all children of the ViewGroup (text colour, image etc) based on the state of the ViewGroup, preferably without having to hook up complex logical code. This seems like a fairly common sort of requirement, so I was hoping it would be straightforward in Android - am I going to be disappointed?
View 1 Replies View RelatedI'm a little confused by what I'm seeing with regards to phone state transitions via the PhoneStateListener. When I receive a call, this is what happens: (call comes in) RINGING -> IDLE (I pick up) OFFHOOK (I hang up) IDLE It's that first transition from RINGING to IDLE without any interaction from me (not ending the call, not answering the call) that confuses me. Do I really have to implement an idle counter to know that an incoming call has really ended? Seems like the reported phone state represents some sort of phone state that isn't the obvious one.Is this a bug or am I just not in tune with the paradigm here?
View 2 Replies View Relatedtrying to create a broadcast receiver which responds to system events and change system settings. I don't need any interaction from the user so I don't need an activity and have been trying to do everything through the manifest file. I've put a log event into my onReceive method but it never logs anything so I'm presuming my method is never called. I've tried this with both the 1.5 and 1.6 SDKs. I was hoping somebody could have a look at my code please and let me know if there are any problems.
