I'm pretty sure no one but me is using UDP broadcasts but in the rare chance that someone is - has any experienced this? I use UDP broadcast to do LAN multiplayer games - it's how clients discover hosts of games.The EVO can't ever see the games when all my other phones can.

I know that the apps receive a ACTION_SHUTDOWN broadcast event when the device is shutting down.
When an application receives the shutdown, is there still an opportunity to send data packets out, or does android block such attempts(or does the platform tear down the network stack before it can go out).
I'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.

We are able to see the UDP packets reaching the host machine, but not able to reach the emulator, In Wireshark we are getting "Destination port unreachable" The port we are using is:49152 and static ip at both ends.Is this port supported by android emulator? What is the solution to get UDP packets to be able to reach till the emulator?
View 6 Replies View RelatedI'm trying to receive data from a multicast address, but the call to MulticastSocket.receive() blocks until a timeout takes place.I did some network sniffing and found out that my device (and the emulator) never send a MulticastSocket.joinGroup request.I tried running the same Java code from my PC as a standalone application and it worked well. Could it be that the Android platform blocks IGMP join requests?Has anyone succeeded with Multicast on Android before?My manifest file contains the following permission:I am running my application on 2.1 (Both emulator & device).Any ideas anyone?

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.
View 2 Replies View RelatedI am developing an application which is communicating with the server. Tha application can perform log-in and get different parameters from server.
The application consists of a RESTful client (custom class for making requests), Communication Service (the service which runs in the background) and the main activity.
For now I created multiple broadcast messages and multiple broadcast receivers in the main activity so when the application performs login operation a receiver (loginBroadcastReceiver) in the main activity receives a message and when another parameter is received from the server different message is broadcasted and another receiver handles the message.
This way however the application performance is poor but I am not sure whether it is due to multiple broadcast receivers.
Does anyone know what is the best way to exchange data between service and main activity - is it better to create a single broadcast receiver and retrieve all parameters from message or is it better to initialize multiple broadcast receivers for multiple parameters?
I have an IntentService that broadcasts an Intent each time if finishes some work. Each broadcast Intent is identical except that it contains a Bundle with some result information from the IntentService. Evidently, having different data in the Bundle is not enough for Android to think it's a different Intent. If the IntentService broadcasts two of these Intents back-to-back, the second one is dropped as a duplicate.
I know I've read about this behavior in this forum in the past but I can't find in the documentation where this duplicate elimination logic is described in detail. Mostly, I just want to differentiate the Intents enough that they are not considered duplicates. Any pointers would be appreciated.
I 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 7 Replies View RelatedI have an application that acts as both client and server. I have a scenario that I need to test that involves three devices. One of them needs to broadcast a message (UDP) to the other two. Running on physical devices, this is not a problem, and it works fine. On the emulator however, this is much harder. I have managed to get it work for two devices using the emulator. Here my client thread broadcast the message to 10.0.2.255 port 6002, and server thread listens on port 6006. By using redir add udp:6002:6006 the server receives the message fine. Now, if I add another instance and do the same portforwarding, only one of them receives the message. I also tried to use a different port number on the server, and forward port 6002 to that number, with the same result. It appears as if a port can only be forwarded from one instance. Does anyone of a method to broadcast using the emulator, without sending a separate message to each emulator instance?
View 4 Replies View RelatedI've tried these phones: Motorolla Backflip 1.5, Nexus One 2.1
Basically I register BroadcastReceiver to get ACTION_HEADSET_PLUG broadcast and look on 3 extras that come in intent:
state
name
microphone
Here is the description from API:
* state - 0 for unplugged, 1 for plugged.
* name - Headset type, human readable string
* microphone - 1 if headset has a microphone, 0 otherwise
Issue #1: Broadcast comes when activity is started (not expected), when screen rotation happens (not expected) and when headset/headphones plugged/unplugged (expected).
Issue #2: Backflip phone (1.5) sends null for state + microphone, 'No Device' as name when headset/headphones unplugged, and sends null for state + microphone, 'Stereo HeadSet'/'Stereo HeadPhones' as name when headset/headphones plugged.
UPDATE: T-Mobile G1 with 1.6 behaves the same as Backflip phone.
Nexus even worse, it always sends null for state + microphone, 'Headset' as name when headset/headphones plugged or unplugged.
Question: How it can be explained that API is broken so much on both 1.5 and 2.1 versions and different devices, manufactures?
UPDATE:
Code in onCreate of main Activity:
CODE:.........................
Now the code of BroadcastReceiver:

View 5 Replies View RelatedI am making a widget that needs a broadcast receiver, like the one in com.example.android.apis.appwidget.ExampleBroadcastReceiver. However, the example defines Intent.ACTION_TIMEZONE_CHANGED in the manifest, but there are some that do not allow this. For example, Intent.ACTION_TIME_TICK says "You can not receive this through components declared in manifests, only by exlicitly registering for it with Context.registerReceiver(). "
So I removed the manifest declarations and tried replacing the AppWidgetProvider.onEnabled function that was in the example with a call like the following: context.registerReceiver(myReceiver, new IntentFilter(Intent.ACTION_TIME_TICK));
(where "myReceiver" is an instance of the receiver I want.) However, when I try to run the code, I get the following error:
Unable to start receiver...android.content.ReceiverCallNotAllowedException: IntentReceiver components are not allowed to register to receive intents.
Any way to get this broadcast receiver working from a widget?

View 2 Replies View RelatedI wish to listen to android.intent.action.BOOT_COMPLETED. However I am not getting the broadcast intent, if I specify com.test.BootBroadcastReceiver in the manifest. When I change this value to simply BootBroadcastReceiver, then I am getting the broadcast intent.
