Android :: Activity Of Killed Process Still Visible In List After Home Pressed
Sep 23, 2010
like many others, I want to kill my Android application on "exit" button. Really kill, not just move to background and stop all active code. (I know very well that Android does not like it.) I found Process.killProcess(Process.myPid()); and System.exit(0) which both work fine (I have no problem with activity stack, the "exit" button is in my base Activity.). But there is a problem. When I kill my process and I am back in the shell, I press [Home] button. It shows list of applications that are on the background including my application which has been killed.
Is there a way how to do both: 1) kill the process and 2) remove it from the Android application list that is shown after user presses [Home] button? Thanks for all replays (with the exception of that stupid "you should not exit applications explicitly on Android"

I have a problem and that is my SplashScreen I have. It is built as an intro and after 3 seconds it shows the main menu of the program. Anyway, if I press down Back or Home button during the time the SplashScreen shows, it closes, but the activity I have chosen to follow after the SplashScreen will still run after the three seconds.
My code: **UPDATED CODE**
Handler ur = new Handler();
myRun = new Runnable() {
public void run() {
mainIntent = new Intent(SplashScreen.this,MyApp.class);
SplashScreen.this.startActivity(mainIntent);
SplashScreen.this.finish();..........................

Whenever the memory needs to be reclaimed, the process is being killed by Activity Manager Service in killPidsForProcess. I have a back button in my activity window on right corner of the title bar.
I want to kill the activity completely on clicking the close button. Can I reuse the same function and will it have any major effect? Please help me out in this.

I saw another thread related to this question, but did not find the answer that was useful to me. Is it possible when the user presses the Home button to be able to finish() my activity somewhere? I saw that people were having problems with using onStop(). Has anyone found a resolution to see if this is always called on Home being pressed?

I'm trying to do something which really ought to be quite easy, but it's driving me crazy. I'm trying to launch an activity when a home screen widget is pressed, such as a configuration activity for the widget. I think I've followed word for word the tutorial on the Android Developers website, and even a few unofficial tutorials as well, but I must be missing something important as it doesn't work.

I have developed an App that launches and works fine on Android 1.5 and 1.6. When I try and use it on version higher then that the app's activity starts, progress dialogs pop up and I can see my Async Task executing and the info being returned via Logcat. No errors or exceptions are shown. But the Activity never displays. All I see is the progress dialog showing over the home screen and then nothing. The process is active and running under the DDMS view.

I have a spinner, which mostly works. If a user selects one of the items in it, the 'onItemSelected' routine catches it just fine.
But if a user clicks the same spinner, but does not change from the already visible item that it's currently displaying, the 'onItemSelected' routine just ignores it, and the logs show:-
WARN/InputManagerService(577): Window already focused, ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy@437948b0
I there anyway to capture someone doing this? The idea is that my spinner contains a list of names, and when a user selects one from the spinner, it gets added to a listview.
I could just add another button to get the name from the spinner, but, screen-space is already lacking and I'd rather not add anymore content.

I will try to be as brief as possible... I have published a very simple android application it's name is "Vib-e-rator PRO". It's purpose is obvious, it can be used as a masssage vibrator or as an erotic stimulator...
My Problem is don't have an Android Phone to test my app in real time.
I have been recieving mixed comments from people. A few users say its working fine. But majority of them complained that the Phone would n quit vibrating even after the closing application.
Later i speculated that when ever the user switched off the vibrator and quit the app it would work as expected. If any user (most of em) directly closed the application ( either through the close option provided in the app itself or by pressing the END button in the phone ) without switching off the vibrator then it would not stop vibrating.
So i added myvib.Cancel() (myvib is the context for Phone Vibrator) in the exit block the close option provided in my app. For the other scenario, when it is closed by pressing the END button in phone, i have no idea how to solve it... So friends please advice me what is necessary to do... The comments i have been receiving from many users of my app is really embarassing....

I have an app with multiple activities and a local service.
if I finish() all the activities and stop the service, the process still exists (if I go into adb shell and type ps, I still see it).
is there a way to make sure the process is killed when I "quit"?

I am writing a program where I need a ListView for which I am using a ListActivity. Each one of the views within the ListView has four buttons, (Off, Dim, Bright and On). Each one of these buttons is configured with it's own OnClickListener when I build the view. This part seems to work ok. However when I have say 5 Views each which has these four buttons, I can tell whether an off, dim, bright or on button was pressed but I cannot tell from which view it was pressed. So for example if my views are devices (Light, Heater and Kettle) I press an "on" button and I know an On button was pressed but how do I get it to tell me the On button for the Light was pressed?

I have a service running in the background. It starts on device boot. Also, I have one activity (that appears in the task launcher) in which I have provided buttons to start and stop the service.
Now, I install the application on the phone and I start the service using this activity (and not on-device boot). As expected the service starts and starts doing its designated task. I no-longer need the activity. So it goes out of sight and may not be required for a long time now.
My question is, now, if the android platform kills this activity, will it kill my service too ? (This is because I see that after few hours, my service is not running anymore.). If this is true, then will the service continue running longer if the service was started on device boot.

I am working on a MVC implementation for Android (to be subsequently hosted on SF and/or GC).
It works like this:
Activity (View) <=> Application (Controller) <=> Data (Model) <=> Persistence (DB/Network etc)
The scenario is:
1. Activity launch (main/launcher)
2. Notifies Application about performing a data transaction
3. Upon receipt of data response, controller devices which Activity to launch (or update existing)
4. Application has overridden the method onConfigurationChange
Problem: When the orientation is changed, the Application is notified about onConfigurationChange but:
a) The "current" activity is Destroyed and recreated -- which is fine to some extent b) The new instance which is created is automatically => onCreate, onPause, onStop, onDestroy.... now that's catastrophic.

I created a thread in my activity, and that thread will print out the value of my instance variables in my activity after running for about 10 seconds. I pressed the back key to destroy my activity before the thread prints out the values, and when the thread reaches that line of code, it can still print out the values correctly. That means even though the activity is finished, the java object of the activity is still there. Will the object always be there? Or it is just waiting to be GCed? Or it will be killed only when Android needs memory?

My app is comprised of a set of reusable Activities that other apps can reuse. For various reasons, I would like my Activities to be launched in context of the invoking Activity's process, instead of always being launched in my Activity's process (default behavior on Android). How can I achieve this?

While developing a sample android application I have constructed two activities
1)Activity 1
2)Activity 2
Now Activity 2 is the foreground activity whereas Activity 1 is the background one. Now user presses Home key. The application(i.e. both the activities) disappear. Now is we relaunch the application we see Activity 1 as the foreground activity. My question is:
1)Does the platform maintain any history entry when pressed home key?
2)How do we take the user to the last launch activity on relaunching the application?

I have a layout that is three linear layouts. The top has some icons and the middle has a tabhost. Each tabhost has a list inside it. The bottom linearlayout has two buttons that should stay at the bottom on the screen at all times. The problem is when a list in the tabhost gets too long, it displays over the buttons. I tried to find some way to get the buttons to bedisplayed over the list but have failed so far.

Is there a way to notify an activity/service of a force-close request right before it gets killed?
I mean when the user hits the force close button in Menu>Settings>Applications>Manage applications>app name>Force Close.

I did a halfa** search of jsut this fourm because I'm at work and it is the only one I can get to. I was wondering if any of the rooted Linix gurus around these parts knew of an easy set of commands I can type using ADB, or a quick patch that would return my phone to the home screen when end call is pressed. It is drivig me crazy. I know about the program NotCallLog, but before I install yet another program onto my baby.
