If it is possible to keep an Air for Android application alive during sleep, how can it be done? I know how to prevent sleep and lock but this course is not preferable to some users.
Update
The reason in this case is to keep the video streaming from the phone to a server.
There seems to be a solution for the random shut-down problem with Captivate: Captivate Keep Alive app. This was just posted, and it really seems to work! Give it a try. So far I've been up for more than 24 hours without a shut down event.

Code:
I/ActivityManager( 152): START {act=android.intent.action.MAIN flg=0x4000000 cmp=com.android.phone/.CallFeaturesSetting} from pid 1745
E/MenuItemImpl( 1745): Can't find activity to handle intent; ignoring
E/MenuItemImpl( 1745): android.content.ActivityNotFoundException: Unable to find explicit activity class {com.android.phone/com.android.phone.CallFeaturesSetting};
have you declared this activity in your AndroidManifest.xml?
That's what i did:
-Check out Android Source with repo, Tag 4.0.3
-Edited frameworks/base/voip/java/com/android/server/sip/SipService.java
-lunch full-user
-make
-Copied the resulting Phone.apk and Phone.odex from out/target/product/generic/system/app/ to my Phone and fixed permissions.
The ApplicationManager is killing the process of my application when the user presses on "FORCE STOP" on the Aplication Manager.According to the documentation a broadcast action is.The user has restarted a package, and all of its processes have been killed. All runtime state associated with it (processes, alarms, notifications, etc) should be removed. *Note that the restarted package does not receive this broadcast.* The data contains the name of the package.How can I listen that action in my application; I have tried creating a BroadcastReceiver on my package, but the onReceive() is not called.

We have had a couple users on the myTouch phone have issues in our application. It apparently is force closing on them. I am not sure of why it is, and the 1.6 SDK is not out yet. Has 1.6 been released into the wild? If so, do you know where I can download the image for my G1 dev phone to test w/?
View 7 Replies View RelatedI have an app which declares a BroadcastReceiver, the receiver gets the broadcast, does what it needs to, then ends ensuring that everything is tidied up as needed. When I examine the system through the DDMS view in Eclipse the process for the application is still running after the receiver has completed. I've even boiled it down to a simple test case which gets a shared preferences instance from the context, checks a random setting, and then exits, and, when run on the 1.5 emulator (which is the minimum supported OS level) the process is still hanging around.The reason this is an issue is memory usage (which shows under DDMS as around 2MB).I've had queries about why the application still uses up memory even when it's not doing anything, so, my question is; Is this behaviour normal, or have I missed something that would make the process exit?
View 9 Replies View RelatedIs it possible to keep service alive even if the foreground app does not run anymore? My app consists of a foreground app (UI) and a service that should keep running in the background until it is being explicitly stopped by the user (similar to a music player). The problem is that if the user opens other apps, my foreground app is being killed by the system (makes sense) but then also the service is being killed by the system (does not make sense).

I just wondered which frequency is OK to send whitespace keep alive packets onto a TCP connection to keep it alive on a T-Mobile 3G connectivity (the use case is to maintain an idle XMPP session alive). On SFR in France, we are disconnected if idle for 3 minutes, but I guess T-Mobile's timeout is lower. By the way there is a bug in the Smack library, the "keep alive" setting is not enforced, e.g. if you set it to 30s, in the worst case the whitespace will not be sent until the double of this time (60s).

View 3 Replies View Relatedam developing an app that needs to track incoming calls. I have set up a phonelistener which is launched form a service like so
TelephonyManager tm = (TelephonyManager)getSystemService (TELEPHONY_SERVICE); tm.listen(mPhoneListener, PhoneStateListener.LISTEN_NONE);
This seems to work for a while but then fails to fire after - say an hour. I have tried relaunching the listening in a timertask every 60 seconds but this does not seem to work. Is there a way of keeping a listener alive for a long period of time. I can only assume the system is garbage collecting it.
How do I make my service always alive?? If my service gets killed because of an exception or if the VM kills my service on low memory, How do I make sure that my service is always running?

When a try to deploy my android App in the emulator, after the application(.apk) gets loaded in to the emulator, when I tap on the menu button in emulator for loading my application's initial screen, its is raising me a alert message with this information:

How can I avoid this issue that is happening at all time, When this happens, unless I tap on Wait button, I can't able to proceed.
I want my service keeps network connection alive even if user presses the power button to shutdown the screen. As I have tested, socket will return exceptions and through CONNECTIVITY_ACTION intent, i know EXTRA_NO_CONNECTIVITY is true. So can current Android keep connection not closed when screen is off?
View 3 Replies View RelatedThe default way configuration changes (i.e., rotates) are handled is to destroy the activity & recreate it with a new one. What is the recommended way to handle these changes in an activity that binds / unbinds to a service (that is possibly heavy/slow to start)? When the activity gets destroyed, it unbinds & causes the service to be destroyed. When the new activity is created, it binds & recreates the service.
The only choices seem to be:
-- override onConfigurationChanged in the activity. Feels ok, but non - conformant.
-- explicitly start the service & only stop it when the last activity gets an onDestroy that's not due to a config change (i.e., there was no call to onRetainNonConfigurationInstance). Feels icky.
-- explicitly start the service & don't stop it until some amount of time after the last unbind. Ickier.
On a related note, what happens between activity switches within a process, where the first activity (A) starts the next activity (B) & then calls finish() -- is there a guarantee that B.onCreate is called before A.onDestroy? If not, and the activities share a service, the same issue of keeping the service alive during this window exists, but with only the icky workarounds.
Trying to understand the Android framework model. I have an application that needs to have several threads running. On thread gets GPS fixes, another picks up GPS fixes and pushes them to server, and yet another occasionally polls a server for dispatched orders. Some of these threads update status Views as well.
Since I am new to Android, the application framework model hasn't clicked for me. Where are these threads started? Right now I start the threads in the initial Activity, but if I understand it right, once that Activity goes invisible it is stopped. Furthermore, I have to track GPS and network statistics so that I can have a View which may (or may not) be the active View.
Is there a way to keep an Activity in memory after the user hits the back button on it?ActivitySearch is used frequently in my app, however after the user starts it up, then hits the back button, it's destroyed, and the next visit to it requires it be built from scratch again.If after its first construction, I could just request it be paused instead of destroyed on the back button, then I could reuse it. Is there a sensible way of doing this?The only way I could think of reasonably doing it is to combine ActivitySearch with ActivityMainMenu into a single activity, and simply switch views when the user chooses search, but this is probably a bad design.

View 5 Replies View RelatedOnce we call the startService() method, can we keep the service alive until its explicitly stopped by the user? I want my service to stay alive until the phone is switched off. How can i do this? The idea is that when I receive an incoming call, I want to start recording and once the status changes to idle, I want to stop the recording. I am doing this inside my service.

View 2 Replies View RelatedI am currently firing an Intent to a Broadcast Receiver which in turns starts an Activity.
Then from the same Service another Intent is fired to a Broadcast Receiver thats in the Activity.
The problem is that the Activity isn't getting the Intent meant for it because it is fired before it is alive and the Broadcast Reciever is registered.
I was wondering is there anyway to make sure an Activity is alive before sending an Intent?
