Android : Way To Launch A Service At Startup?
Jul 22, 2009
I have a need to create a background service that starts up during the system boot up, and keeps running until the device is powered down. There is no UI or Activity associated with this. I created a class extending the android Service class, and added the setttings to the AndroidManifest.xml file. When I launch this service in the emulator, I don't see this launched at all. I have overrided almost all the methods in the Service class to put log statements, but none of them shows up.

I have plenty of applications that I only use like once a month or even less. Yet, many are always on, for no reason. What are my options to make it so that they ONLY run when I need them? I saw that they are apps that constantly watch the processes and kill them every time they appear. That doesn't seem like a great approach, not very efficient. And What if I want to use the app?

I have a ListActivity and a MapActivity. I would like to launch either one of these activities on application startup that has been chosen by the user in a preferences window.
So far the only way I see to launch an activity on application startup is to specify it in the application manifest file using...code...
I am thinking I might have to start an activity that does nothing but looks at the user preferences and then launches either the ListActivity or MapActivity. Seems like a waste to have an activity do nothing but launch another activity. In my research I have not found any solution to this problem.

Android Market has a neat feature allowing you to launch it using a url in the format of market:// ... Is there an equivalent method for launching an application using a link?

I want to create an app or background service that just listens for the launch of a 'default' app, say Contacts or the built-in Gmail app. If the contact app is clicked, I want to transfer control to my app temporarily (e.g. present a Yes/No popup to the user or increment an internal counter of my app ) and then redirect the user back to the app that was clicked. I want to do this only for a couple of 'well-known' built-in default apps, not any third party apps..

How do you pass an intent from a service to a new activity launched from a main activity? There's a passextra( intent src ); but I don't think thats what I am looking for?
activity main > start service( intent wuteverserviceintent );
activity main > start activity( intent newactivityintent );

Every time I start my phone it seems that every program in the app catalog starts up. Until I activate the Advanced Task Killer and shut them all down, the thing runs like a hog. I have quite a few programs installed, but I dont use them all all of the time. Why do they all start up and is there any way beside the ATK to stop them? Is there any way to modify the startup files?

I have the same service in multiple APKs. In each of the APKs, I am going to launch the service. Because the APK are difference "applications" that have been installed & upgraded at various times, the service implementation in each may be different. I am trying to figure out a way to make sure startService() runs the implementation that is newest.
I have been fiddling around with PackageManager and Manifest meta-data and categories but I can't seem to get my head around it. It's really a leader-election problem... has anyone ever done this ? Any clues?

I have a service running in the background.I have a background thread that gets a reference to the service from the application's main activity. But when the background thread calls a method in the service to display a toast, I get the "Looper not initialized exception".Why,if I have a valid, bound reference to a Service, does this still happen?

I am trying to run the sample soft keyboard included in the SDK. I am using the debugger, and the literature says that to use a breakpoint while debugging a SERVICE, I need to include:
android.os.Debug.waitForDebugger();
So here is the portion of the code I modified:
CODE:...........
I have put a couple of breakpoints, at the statements indicated by the comments.
This is what happens: the debugger first stops at the breakpoint1, for a few seconds. But then the service restarts. For the life of me I can't figure out what makes the service to restart.

Is there any way to get an app to run at startup? There is a volume control app (ladybug icon) that I use to keep my ringer volume always at vibrate. When I accidentally hit the volume rocker, the app returns the ringer to vibrate. However, I must remember to run the app when I restart the Droid. So, is there anyway to have it run when the Droid powers on? Or is that something that would have to involve rooting?

My service works exactly the way i want as long as i use start and stop and communicate using intents. However my activity needs to change the state of my service as well as retrieving state information.So i thought it would be nice to broadcast some kind of state_changed event from my service and use a binder interface to pull information from the service or change the services state based on user input.This works fine too. The only problem is that my service gets killed when i unbind it just as the documentation says.Is there any way to keep the service alive but still get an interface to control it directly. My activity offers the user a way to stop the service and the service kills itself anyway after it's work is done but i don't want the service to stop every time the activity is destroyed.

Other than downloading a 3rd party application that auto-starts apps on boot, is there a way within the OS itself to autostart programs when the phone reboots? I have a few apps I use for work and would be nice if they autostarted on my Droid without having to launch each one independently.

I've been modifying/editing parts of the Android platform, but have run into a problem when trying to test my edits. After making my changes to the platform source, I was able to successfully compile the source - thus creating system.img, ramdisk.img, and userdata.img. When I go to test this in the emulator, the emulator just hangs on the "ANDROID_" screen, with the underscore blinking, but never seems to load. Any suggestions? The command I used to run the emulator is as follows:
./emulator -system $HOME/android/platform/out/target/product/generic/system.img -ramdisk $HOME/android/platform/out/target/product/generic/ramdisk.img -data $HOME/android/platform/out/target/product/generic/userdata.img

I have Listpreferences in my app. They don't appear to be setting to their defaults right after installation - they appear to be null. I'm trying to figure out why my default preferences are not being set right after installation.
In my main code I have:
CODE:......
Right after the above code executes, each variable contains "defValue" instead of the actual values I have assigned in my ListPreference below.
My preference xml file is called, "settings.xml". Here's what one of the ListPreferences there looks like:
CODE:.............
Here's what some of my strings.xml file looks like:
CODE:.................
When I go to menu, and then settings, I can see my defaults checked (radiobuttoned). Then when I go back from the settings menu to my main screen - all is well - for life! ...then each var above is assigned the proper default value.
This only happens when I first install my app on the phone. After I go to the settings screen once and then right out of it, the app is fine and accepts any setting changes.
By the way, as you can see, "List1" is the android:key within a file called settings.xml in my res/xml folder.

1) I have a Spinner with several options provided by an ArrayAdapter and have an onItemSelected listener on this Spinner. When selecting an item from the spinner, I want to display another view (list-view) but this method is unintentionally invoked upon initially displaying the view. The list-view is therefore displayed upon startup of the application. It is possible to add a spinner-on-item-select listener that won't fire upon initially displaying the view but only by the user selecting an item?

I have a Nuvifone A50 (Garmin-asus), after wiping all data on the device, i can't accept areements, application is crashing and back to step 1.I'm SURE the phone is perfectly working exept this, so if i can bypass this, the phone will work. I tried restoring the .img file, same problem.
Pictures:

Step2 screen.nicow .me/rpbOtMjVBI.jpg
Step3 screen.nicow .me/vEVrnJin1g.jpg
Step4 screen.nicow .me/TFQSv4cvVf.jpg
And after the force close, back to step 1.I can access the file system via USB, nothing more. I can also dial(and i can call).

what I'm trying to do here is implement something like a peer-to-peer client. Being that, it will start a client thread and a server thread.I know Services themselves run in the main GUI thread, so I'll have to start a couple of independent threads (or Asynctasks?) for each server and client. The only thing I'm not so sure about is if I'll better have 1 Service starting 2 threads, or maybe 2 services, each one of them starting their own thread.
