Android :: ACTION_USER_PRESENT BroadcastReceiver Not Be Registered In The Manifest?
Aug 30, 2010
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
CODE:.......................
My manifest is fairly simple:
CODE:........
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 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.

I am trying to understand the main differences between registering a BroadcastReceiver in the Manifest and registering it programmatically...
My understanding is basically as follows - would appreciate someone correcting my points if I am missing something.
Registered in Manifest:
- The OS will magically find and instantiate your class if needed, calling the onReceive() method, regardless what the running state of your application was
- Your receive will only get called once per broadcast (i.e. You can consider that registering in the manifest is like registering your 'class' for receiving the broadcast - and the broadcast instantiates your class as needed) (??)
Registered Programmatically:
- registering in code means that you are registering instances of your class to receive broadcast messages (i.e. if your code is a little sloppy, and you manage to register several times, you will end up with multiple BroadcastReceiver instances all having their onReceive() called for a broadcast
- to deregister, you need to deregister the specific BroadcastReceiver instance that you previously registered
- if your application gets destroyed by the OS, your onReceive() method will not be called for a broadcast

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?

I'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?

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?

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 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:
CODE:.......
How to make my code generate just one session per app-launch?

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.

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?

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.

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'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?

I have a family plan and a Samsung Fantastic for Verizon and its a droid. I live in the US. Recently it said when i tried to call a pal that I was "not registered on network" and the call wouldn't send, the same with texts or anything, nothing would work. I tried turning it on and off and it was all the same. It claimed I had no sim card inserted. Meanwhile the sim card was there.

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?

My use case is to launch one of settings app screen when I receive a certain event in idle state. For which, I added my new intent to PhoneAppBroadcastReceiver() in PhoneApp.java (looks like this receiver handles the misc intents) But when i call startActivity(), The phone seems to go into a panic ex. startActivity(new Intent(this, NetworkSetting.class)); My questions are is this the right approach to go about ? If so 1. How can I launch the activity inside of broadcastReceiver? secondly 2. How do i verify if the activity i want to start is already started?Can the NEW_TASK_LAUNCH be used to verify this ,

I have written an application to read all incoming SMS and if the SMS contains certain string, I will also send a copy of the message to my another phone for backup purposes.
I used the reference from the following website:
http://www.anddev.org/novice-tutorials-f8/recognize-react-on-incoming...
It uses BroadcastReceiver to get the incoming SMS, but when I tried to send it using the following method:
CODE:.............
It always crashes. Any idea how to resolve it? Is it because of using BroadcastReceiver.

I have an app widget that extends an AppWidgetProvider to create an application widget.
I would like the application widget to be idle until an activity in my app runs; actually when a service in my app is started.
Once that service is started, I need to "wake up" the application widget and communicate with it (i.e. tell it things to display).
So I see that AppWidgetProvider simply extends BroadcastReceiver -- so does that mean:
1. I need to call registerReceiver in my service and tell it to filter for certain kinds of events?
2. Can I even do #1, or will an AppWidgetProvider *only* accept ACTION_APPWIDGET_* intents?
3. If #2 is correct, how can I communicate or "wake up" / trigger the application widget?
4. Can I send events to my app widget using sendBroadcast( intent )?
Then, my app widget has some buttons on it, I need to send an intent back to the application (or service). I see you can do that with PendingIntents, but if i send the different intents it to the same Activity, it seems to re-use the first created pending intent.

I want to start a project which contains a BroadcastReceiver and an Activity. The BroadcastReceiver doesn't communicate with the activity. But they share a same resource. Can i do it in only one Project (that means, i use only 1 apk to install both BroadcastReceiver and the Activity on my phone), or i have to develope them seperately in 2 projects.

Can I Receive a Broadcast from a Service? It seem I have to extend BroadcastReceiver to receive broadcasts but I'm already extending Service and I can't extend 2 classes. Do I set up an additional Activity to receive broadcasts and then just pass stuff to the already running Service. And if so, how to I pass additional info to an existing Service? Is there a better way?

How can I best implement a BroadcastReceiver that may need to "consume" the current broadcast (via abortBroadcast()), but it first needs to perform some non-trivial work to determine whether or not the broadcast should be consumed.
The problem is that if the non-trivial work takes more than 10 seconds then the receiver is considered to be blocked by the system and may be killed.
I realise that long-running operations should not be performed in the onReceive() method of receivers for that very reason, and should instead be handed-off to an appropriate service. However, if the current broadcast is to be consumed, then the abortBroadcast() method must be called within the onReceive() method before it returns. If some processing is required to determine whether the current broadcast should be consumed or not, then things can get tricky.
I'm developing an app that can consume some (but not all) inbound SMS messages. For any given SMS message it will need to perform some analysis based on the sender's phone number and the message body (including database lookups) in order to determine if the message is one that is relevant to the app or not. In the vast majority of cases this will take less than 10 seconds, but it is possible that it could take longer on rare occasions.
To get around this I'm considering the following solution.
1. On receiving a broadcast for a received SMS, my receiver starts a background thread to perform the required analysis and handle the message if appropriate. 2. The main thread (currenly executing the onReceive() method) waits until either the background thread has finished its work, or 8 seconds have elapsed, whichever occurs first. 3. If the background thread finished within the allotted time (which should happen most of the time), then the main thread calls abortBroadcast() or not, (depending on the result of the analysis) and returns normally. 4. If the background thread did NOT finish within 8 seconds, then the main thread stops the background thread and instead starts a service to perform the work. In this case it does NOT call abortBroadcast(), and the broadcast will be passed to other receivers (eg the default messaging app) regardless of whether or not the service ends up handling the message. While not an ideal outcome, it is acceptable.

I'd like my app to catch incoming SMS messages. There are a few examples of this around. Looks like we just need to do this:
code:..........
Is this correct? I'm sending my phone some sms messages, but the log statement never gets printed. I do have some other SMS applications installed on the phone, which display a popup when the sms is received - are they somehow blocking the intent from getting passed down to my app, they are just consuming it completely?
