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);
Is 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.
I've looked everywhere in the Developer's resources and reference, but I can't find anything that resembles what I'm trying to do.
Do any one know how to broadcast any intent if new email is received?

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

I am adding some basic alarm functionality to my program via the use of AlarmManager and a BroadcastReceiver class (named AReceiver.java). My problem is that the data I add to the bundle attached to the Intent creating the PendingIntent appears to be lost. The only bundle data I can access in the AReceiver class is a android.intent.extra.ALARM_COUNT=1. Here is the basic code in the main activity class creating the Intent, PendingIntent and the AlarmManager: [Code in main activity - Notepadv3]
Intent intent = new Intent(Notepadv3.this, AReceiver.class);
intent.putExtra("teststring","hello, passed string in Extra");
PendingIntent alarmIntent = PendingIntent.getBroadcast(this, pendingPeriodIntentId, intent, 0);
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, timeOfNextPeriod.getTimeInMillis(), alarmIntent);..................
I want send LinkedHashMap to another Intent.
But I don't known what method for extras is allowable.

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" />

<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.

View 1 Replies View RelatedI'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'm having hard times getting my GL thread (from GLSurfaceView) to trigger some code execution within the UI thread (from Activity). I tried it in every possible way (well not every, I missed at least the good one) none worked.
My idea was to get something called from the UI thread (to update some widgets) when the surface is effectively created. So I added to my onSurfaceCreated method the following call:
CODE:.............
This compiles, but when my GLSurfaceView sub-class is constructed a NoClassDefFound exception is thrown, telling me that the class com.my.package.MyGLSurfaceView$1 is not found.
Here's the log:
CODE:.............
The line 297 in MySurfaceView.java is:
private Runnable mUpdater = new Runable () { public void run () { [...] } };
I didn't found clear answer for why my code does not work. I assume it is because I am trying to update textview from runnable. Anybody know some workaround? Code isn't clean off course, I am happy to get that working so far as I am totally new in java.
CODE:...............................
In an existing Android project I've encountered the following piece of code (where I inserted the debugging litter) code...
with not a trace of the messages from the Runnable. So appearantly the Runnable doesn't run(), although img.post() returns true. Pulling the ImageView in onCreate() and declaring it final doesn't help.
I'm clueless. Simply setting the bitmap directly, while blocking the UI thread, does fix things, but I want to get things right. Does anybody understand what's going on here?

I'm trying to do an insert to a DB as a result of a user clicking on a button. I want to do the actual insert in the background, so it seems I should use a Handler to do this.

View 4 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.
