Is there a way to check before sending a broadcast (from a remote service) whether there are registered broadcast listeners? What I'd like to do is to send broadcasts only if there are registered listeners, otherwise make a toast. Does it make any sense?

I have a snippet of code that I'm calling from a service:
CODE:........
What I would like is a way to check and make sure that the registerReceiver isnt already listening before it calls it again. Is this possible?
For example if my snippet of code is in a method, and I call the method 10 times, right now the onReceive method appears to run 10 times.
I have a program that monitors incoming SMS's, and I want it to monitor them full-time, so I registerReceiver with a Broadcast receiver that I've created. The problem is, if I want to unregister that receiver, I can't unless I know the original Broadcast Receiver class I registered. This is not a problem if I set it to stop when the program stops, but I want the receiver to keep running, only stopping when the user specifies. EDIT: Or is there a way of "Storing" the Broadcast Receiver class that I've created, such that when onDestroy is called it can be saved and when create is called again it can be pulled out.Is there any way of doing this?
View 1 Replies View RelatedI'm using more than 1 instance of MapActivity in an application that look different from each other. I'm running into an issue sometimes when leaving a MapActivity doesn't unregister it's BroadcastReceiver and going Back to resume the MapActivity page it tries to re-register the receiver again, thus receiving an Exception that Receiver already registered.
Anyone know of a way to tell if a Broadcastreceiver is registered and is listening?
Currently my application is configured to always receive the CONNECTIVITY_CHANGED action to force an update if the previous update failed because there was no connectivity. What I don't like about this is that the broadcast receiver gets to be called too many times although it is not needed. I was thinking to register my broadcast receiver only if an update failed using the Context.registerReceiver(BroadcastReceiver receiver, IntentFilter filter) method. But I'm not so sure if this is a good idea. I'm concerned that if my application is evicted from memory the broadcast receiver will be unregistered or lost and my application will not be notified about the future CONNECTIVITY_CHANGED actions. The update is done in a short lived service. So if the update fails, the service will register the broadcast receiver just before it ends its execution time. Can somebody explain what happens to my broadcast receiver after the application is evicted from memory?
View 4 Replies View RelatedI have been able to register and unregister a broadcast receiver from the java code and know that a broadcast receiver is unregistered (even if it is not done explicitly) on its own as the process that registered it is killed. Now I have a broadcast receiver which has been registered through manifest file and not through the java code, and need to unregister the broadcast receiver from the java code. Since this, i think would need a reference to System context that instantiates the broadcast receiver.

View 2 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.

I have two questions about sensor listeners
1. from which thread are sensor values updated and should this be synchronized? can sensor's listener callback be a good place to call custom's view onDraw method? as this should be done from different thread. I cant find anything about it. In another words my problem is that I want to listen to sensors change and draw something on view surface but I dont know which thread (the main thread of the application?) is updating sensor's state
2. If I register sensor listener with SENSOR_DELAY_FASTEST my application is not responsive at all! Raw application with TextView only is not reacting to go back or home button! How should I deal with this or am I doing something wrong?
I would like to know how to run a listener on an isolated thread. Because I would like to use a LocationListener and make some calculations in the main thread. So the LocationListener would be "slow down", because of those calculations. Is it possible to have it run in a different thread? Or is it by default in a separate thread?
View 2 Replies View RelatedI have following code:
CODE:...........
Code is working but here goes my problem: when I call it from main activity in this way:
CODE:........
Then i can see 10 times result of 'doing sth else!!!' and when loop is over i can see then result from activity. So sensor activity waits for some reason and then when main activity has nothing to do, sensors are doing their job.
of course I have well implemented: onActivityResult(int requestCode, int resultCode, Intent intent)
I want to read sensord data directly, not using listeners, is it possible?
trying 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.

We have a very simple ViewFlipper widget in a layout. The following trace back happens when it crashes. This does not trace back into our application code at all.
There is a similar bug logged for 2.1 http://code.google.com/p/android/issues/detail?id=6191
We are running on 2.2 and getting this error.
Is this fixed or is it necessary to create a workaround subclass?

I am implementing Localytics.com useage statistics in my Android app.
I am still just testing.
I note that just starting my app and then immediately exiting will register two sessions (as they are called by Localytics) in the live statistics.
I have followed the guidelines in Android Integration.
My app consists of a main Class of the TabActivity type. This TabActivity holds two tabs in which I display two other activities.
Like this:
CODE:..............
I instantiate the Localytics object in all three Activities like this:
CODE:............
So, the above code lines are repeated in each of the three Activities. In the TabHost Activity (only in this Activity) I then follow the instantiation with a this.localyticsSession.upload();
And then (only in the TabHost Activity) I have these to finish things off:

How to make my code generate just one session per app-launch?
I see that multiple broadcasts (ACTION_TIME_TICK, for example) cannot be registered in the manifest, the must be explicitly registered via Context.registerReceiver(). I am having trouble with the ACTION_USER_PRESENT broadcast intent. Specifically, I test on the emulator and my application keeps force closing with the error:
CODE:...................
This is caused by

My manifest is fairly simple:

I am essentially attempting to create a Receiver that is awakened as soon as possible after my application is installed. The first time it is awakened, it registers a few listeners, and then it unregisters itself so it is never called again. (I really wish there was an intent fired immediately after your app had been installed, to allow a small bit of setup.
I'm trying to register the phone as a HID device through bluetooth. So far I did the following - Created a BluetoothServerSocket with bluetoothAdapter.listenUsingRfcommWithServiceRecord("Any name", "00001124-0000-1000-8000-00805f9b34fb"). The UUID is the standard one for HID devices. - Paired the phone with a Windows PC - The phone is recognized as "Bluetooth HID device, but I get the error "Device driver software was not successfully installed"
Does anyone know what steps can be taken next to make it work? I think I should register a SDP service record, but I'm not sure if Android Bluetooth API has support for this.
I would like to check which receivers are there for a specific Intent yet queryBroadcastReceivers() ignores receivers that were registered in code using registerReceiver() call. It returns only receivers declared in the AndroidManifest.xml file. Is this behavior by design ? Any other way I can get information on *all* receivers capable of handling an Intent even if they where registered in code ?
I am using viewflipper for fling gesture recognition everything works fine for 2.0 and prior but in 2.2 and 2.1 it throws exception as "java.lang.IllegalArgumentException: Receiver not registered: android.widget.ViewFlipper" below is full debug trace.
CODE:.....................
There is issue on Google related to this bug 6191.
And the solutions mentioned in there seems to work only if your are creating ViewFlipper through code but in my case i am using ViewFlipper in XML which is my layout file and so i cant use the solution mentioned for extending the ViewFlipper i tried using delay nothing seems to work.
Below is my layout code.
CODE:...............................
I am getting IllegalArgumentException: Service is not registered when i try to stop my service by initially calling unbindservice and then stopService.
Before calling unbindService i first check if my service is still bound by checking (mBoundService - obtained from the ServiceConnection) I also check if the service is not stopped and only then i call the unbindService But I still get the error. From the posts that I read only I found out that both these calls are asynchronous and that the service will only stop when nothing is bound to it.
I have a ViewFlipper in my app.
When my app is running and the phone goes to sleep it works fine.
When I wake the phone up and my app then tries to display again, I get the following error.
I can't figure this out.

I've just started developing for android and have released my first app. I'm getting some bug reports about the app not registering shots, like you tap the screen 10 times put the player only shot 9, and the evo 4g seems to have these problems, so please help me! The app: Search for: "Trigger frenzy paintball" on the android market. Or scan this Before you answer these questions, please make sure that you are only touching the screen with one finger at a time.
1. How fast were you able to shoot?
2. Does it feel like the app isn't registering shots?
3. If you can try this app at another phone model, what phone did you try it on? Did it feel like it registered shots better?
Hello everybody so i have this problem that i typed anything when registered at android market and now it asks me to re-login and i only know Username and it wont let me create a new account....

I got the latest update for my Vibrant about a couple of days ago and everything was going fine. Today at work, my phone ran out of batteries and after charging it and turning it back on, I get an error "Not Registered on Network" when I try to dial. I've turned it off, restarted it, taken battery out, taken SIM card out, blew on it, etc and still I don't have any bars and cannot make phone calls.
Any ideas? I want to do a factory reset but all I have done so far to "back up" my files is simply copy and paste all the files on to my laptop HD. Is here a better solution than that? I'm gonna have to reinstall EVERYTHING, right?
