Is there a way to capture a key event from the Menu button using an Intent or Broadcast Receiver? Basically I want my app's Service to be activated when the Menu key is pressed.

I'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
View 4 Replies View RelatedI had one question: Is it feasible to use a BroadcastReceiver as a glue layer between the user interface and the underlying business logic ? Example use case: Suppose i am maintaining the state of a call, and providing callbacks to the UI by invoking sendBroadcast with the relevant intent. Similarly, my underlying business logic can send broadcasts to the activity that has registered for receiving it on certain events ( like call connected, connecting, timed out etc).
View 4 Replies View RelatedIs it possible to use just a broadcast receiver without any activities? I just want to run some sample code only when the phone receives a call and nothing more. I use Log.d to write out but I don't see anything in the log. Am I missing something here? I also have permissions set in the androidmanifest.xml to allow for these type of intents.
View 3 Replies View Relatedsomething weird just started happening. my app has a broadcast receiver which may access the network when invoked. the code has been solid for ages, but in the last few days it has started getting DNS errors on perfectly fine hosts. these are hosts which can be reached without problems in the main app or from other apps.interestingly i've seen another app get DNS errors too another app with a broadcast receiver.seems to affect all OS versions -- we have 1.5, 1.6, and 2.01 here. i don't have a Nexus to test 2.1, though. are there caveats to doing network inside broadcast receivers? i didn't think so, as ours worked fine until the time change [fx: twilight zone theme]
View 6 Replies View RelatedCan anyone give a hint if you know why there are some ACTIONS that do not trigger their associated receivers when they are registered in the manifest while they are received when they are register through registerReceiver() ? For instance, when I declare: <receiver android:name=".MyReceiver"> <intent-filter> <action android:name= "android.intent .action .NEW_ OUTGOING_CALL" /></intent-filter> </receiver> if the application is NOT running My Receiver is never invoked. But now, if I register the intent from inside a service, MyReceiver is invoked properly
View 2 Replies View Relatedim trying to understand what the difference between a service and a broadcast receiver is,as i see it they can do the same thing.For example i have an application : App1 That provide a service called ToastHelloWorld which just creates a Toast and stopSelf(). expose it to other applications using an intent filter with the action name: "com.test.HelloToast"Now i have another application : App2 i want to implicit use a service with the action "com. test. Hello Toast" so i call startService( new Intent ("com. test.HelloToast"));and it works.Why would i use broadcast receivers when i can do everything with services and dont have the restriction of a 5sec execution limit?.I know most "system events" is exposed via broadcasts' but couldnt they just aswell be published as Service Intents?
View 1 Replies View RelatedI started to implement my own App Widget using the example provided in the ApiDemos. In order to update the Widget efficiently I chose the Broadcast Receiver mechanism. In the ApiDemos there is this ExampleBroadcastReceiver which would (or should) react to changes related to TimeZone and Time as specified in the Android Manifest of the ApiDemos. I have debugged this Example using Eclipse and the Logcat output (provoking changes in TimeZone through the settings) and come to the conclusion that there must be some bug in the app widget framework. The only Broadcast Receiver that seems to work is the AppWidgetProvider itself. For instance I would expect something like: D/ExampleBroadcastReceiver intent=XY in the logcat's output after I have provoked the event XY. I have even tried without the 'enabled' option in the receiver's specification in the Android Manifest.
View 5 Replies View RelatedThe online android documentation says: Everything you can do with AppWidgetProvider, you can do with a regular Broadcast Receiver.So, what i want to do is to register via registerReceiver() another event other than ACTION_APPWIDGET_* on my Widget. For example ACTION_BATTERY_OKAY, is there any way to do this? Obviously i cant register the event from the onUpdate() code but i should do it using a service or something else. The problem is that im not able to find any reference to the Provider (AppWidgetManager only returns AppWidgetProviderInfo objects).
View 1 Replies View RelatedI 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 7 Replies View RelatedI am developing an app for android mobiles that communicates with a json/rest web service. I need to make certain kinds of calls periodically to the server to check for some information. Within that context I might need also to query the GPS for the current position. I'm quite undecided to use a Local Service, since I don't know very well how to deal with them, in fact I need to retrieve those data periodically and refresh a MapView accordingly. I heard that I can use PendingIntents,in the service, associate this data as a payload and send them to a broadcast receiver which unpack the data and refresh the UI, I heard also that this is a bad design approach because of what broadcast receiver are intended to be used for.
View 1 Replies View RelatedIn a book I read, the author suggests to extend the application class in order to have a place to be used as a singleton. In this way, it is easy to make some initialization stuff in it onCreate().Now my question: if my application has also some broadcast receivers declared in the manifest, and the application was not started explicitly, or it was but then the os reclaimed it resources back, what will be happening if the broadcast receiver is triggered? Will the onCreate of the application class be called first?
View 7 Replies View RelatedCurrently 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 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.

I'm using: getWindowManager().addView(view, params);I've attempted to call takeKeyEvents(true), however I see that takeKeyEvents first retrieves the Window and then calls takeKeyEvents on that Window.In my case, the Window is null.What this means is that I never receive onKeyUp and onKeyDown calls, which I need in order to intercept some key presses from external input devices (similar to a handsfree set for example).
