Android :: Using Broadcast Receivers
Sep 9, 2009I 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).

Dec 30, 2009Is 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.

Mar 16, 2010something 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 RelatedAndroid :: Alarms / Receivers And Wakelocks
Dec 10, 2009I think I may have found an issue within the My understanding is that to properly hold a device awake after an alarm is triggered you have to aquire a WakeLock in the onReceive() event, call a Service, then perform the work in the Service, releasing the lock within the Service when complete. http://groups.google.com/group/android-developers/ browse_ thread /threa . http://www.mail-archive.com/android-developers@ googlegroups.com/msg66. This pattern can also be found in the CommonWare Advanced Android Development book. I tried this, but I found that the AlarmManager, when calling the BroadcastReceiver, runs on a separate PID than the IntentService when started from the BroadcastReceiver's onReceive() event. This makes the static variable on the lock manager. I tried this, and my logs indicate that the PID is definately not the same, and my understanding is that the DalikVM instances act like a standard JVM, whereby objects and variables are no shared between JVMs. Furthermore, since the WakeLock is not serializable, there is really no way to pass the reference to the lock via an "extra" in the Intent.Has anyone else seen this pattern work or fail? I have an example project (with compiled APK) if you'd like to test it yourself, where shall I post this? I have tested this on the emulator on versions 1.6 and 2.0.

Apr 21, 2010Can 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 RelatedAndroid :: Difference Between Services And Broadcast Receivers
Jul 17, 2010im 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 RelatedAndroid :: Bug Using Broadcast Receivers In App Widget Framework?
May 4, 2009I 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.

Jun 28, 2010The 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 RelatedAndroid :: Finding Which Broadcast Receivers Are Registered?
Jul 2, 2010I 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 RelatedAndroid :: Broadcasts Receivers And Permissions In Two Applications?
Sep 15, 2010I have two applications, one of which (B) implements a broadcast receiver. The application (A) which sends the broadcast, binds a permission to it which the receiver (B) shall possess. The problem is now: If I install the receiver (B) first and the sender (A) afterwards, the receiver will never receive the broadcast. I assume this happens because the installation of the receiver somewhere fails when it comes to the "uses permission" part of the manifest (because this permission is not yet registered/defined).
However, this issue should be resolved as soon as the sender (which defines the permission in the manifest) is installed, but unfortunately isn't. It does not even help to re-install the receiver. The only way to resolve the issue is to completely uninstall the receiver application and do a fresh install. Is this behaviour intended ("not a bug, a feature")?
Android :: Design Approach - Web Service And Broadcast Receivers
Sep 23, 2010I 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 RelatedAndroid :: Extending Application Class And Broadcast Receivers
Nov 1, 2010In 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 RelatedAndroid :: Registered Broadcast Receivers After Application Is Killed?
Mar 25, 2010Currently 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?

Android :: Modes Connectivity Device Identification & Device Inter Communication?
May 28, 2010Can someone explain a couple of very simple concepts to me - I'm interested in mobile devices running android and how they are identified over networks. Some scenarios: Device is connected over WiFi - presumably the device has a standard IP address as with any host and can communicate with any other android host over TCP/IP (assuming it knows the participating device's IP? device is connected over bluetooth - how are devices identified in this case? device is connected over mobile operator's network - this is the one I'm interested in and confused by - is there anyway for two or more devices to discover each other and communicate via the mobile operator's network? How does a device communicate with a backend server in this scenario? In other words, how do apps and devices communicate when not connected to a WiFi network?

Android :: Device Orientation / Mapping Device Y To Screen Y
Oct 30, 2009How do I map the device Y axis to the screen Y axis?I can't figure this out.I'm the developer of Tricorder, and I'm trying to make it so that the accelerometer and magnetometer indicators I draw always point in the right direction.On the G1 phone with the slider closed, all is well.But when I open the slider, I end up showing that gravity is pulling me to the left (if the phone is held with the display vertical).So, I know that the device, and hence sensor, Y axis is always in the direction of the earpiece; and the screen Y axis changes when I open the slider.And I know that I can use remapCoordinateSystem() to change the device axes to match the screen axes.But where do I find out what the device's orientation is?In other words, how do I compute the correct values for the X and Y parameters to remapCoordinateSystem()?
Configuration.orientation seems quite useless.Suppose it is set to LANDSCAPE.What does this mean?Does it mean a device which is "naturally" portrait (i.e. the sensor Y axis points to the narrow end), and which has been turned into landscape mode?If so, which way was it turned?Or does it mean a device which is naturally landscape?In other words, LANDSCAPE could mean that the screen axis is off from the sensor axis by +90, 0, OR -90 degrees.Not much help.So how do I do this?Obviously I want my app to work on all devices, not just the G1 phone.
