Android :: Way To Find Out Current Running Activity From A Service?
Aug 4, 2009
I have been looking for this for a while but I can't find any way of doing it. A contrived example would be a service that simply displays the name of the current running activity as an Ongoing Notification. For instance, when the user is reading a particular email, the name of the activity (hopefully the email title!) would appear in the notifications window and when the user switches to read a text message, the notification would change to show the name of the new activity. Is there a way to do this in Android?

I've created my first service, and it's all gone fine, except when the main activity is stopped. What I want is for a user action (button press etc) to start the service, which it does. Then I want the user, some time later, to press another button to stop the service. Which it does. But if the main activity loses focus (i.e. I go to the home screen) when I return to the activity it has no knowledge of the service anymore - even though the service is still running. When the activity resumes, how do I find out a) if the service is running, and if so b) re-bind to it, so that I can then stop it and collect the data I'm after.

Is it possible to get the currently running activity through Service..?
i.e. I have a service started by an Activity A, and now I want to stop the service by another activty say Activity B.
Since Activity B doesnt know about the service, i want to capture the events in OnKeyDown() of the Activity B in my service...
Is this possible.. How can i get the Activity B's object..?

Is there a native android way to get a reference to the currently running Activity from a service?
I have a service running on the background, and I would like to update my current Activity when an event occurs (in the service). Is there a easy way to do that (like the one I suggested above)?

I have an Android activity running with a custom view in it. When something happens within that custom view, I want to tell the currently running activity by changing one of the Activity member variables. Is there a way to access the current running activity member variables from within a custom view class besides passing the activity into the view class though a function arg?

How to find what service running on background on Android? Maybe I have to ask in another way? Does the service be presented as one "process", then we can use "ps" or "top" command to find it?

When you do a Thread.currentThread().getId(), is the resulting thread id scoped per process or scoped to the current Activity/Service?

I'm trying to create a program with a service that runs every 10 seconds, puts the camera preview, taking a picture and then leaving the user to continue his work (closing down). Currently I have two problems:
1. After I'm taking the picture, the preview still there. There's no function like close() to return to the previous activity. How can I return to the previous activity?
2. I'm trying to run the above described activity from the run() function (from the timer class that execute the run() function every 10 seconds). When I do that, a runtime exception is raised. But when I start the above described activity from a button clicked (not from the timer) it works fine.

I have an API Object that I made, and I would like to share it between a running Service and various Activities in my app, almost like if I was to make the class static. How could I go about sharing the created object between the two?

I have an application in which there will be a service continuously running in background and on certain conditions service should call an activity or pop-up a dialog. I think this is possible. The question is, in case device keyguard gets on say after 2 minutes of idle time then will the service continue running in background. And what will happen when the condition of opening pop-up or Activity is reached.

The default behavior of an activity when BACK softkey is pressed is, GO BACK TO PREVIOUS ACTIVITY. If some the same activity is waiting for some response from server or some data updation is going on and then press BACK, I want to wait on the same screen till the current task is completely processed and then move out to the previous activity.

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?

I have following problem with my application: From my main activity ("activity 1"), there is a menu from which user can launch an action. This action will result in an Intent being received by a BroadcastReceiver, defined in my application. Finally, this BroadcastReceiver will start an activity ("activity 2") to deal with this intent.
The problem is that I have a "quit application" entry in my menu, and I can only finish() currently active activity. ie I am not able to finish "activity 1" from the menu of "activity 2". And I can't use startActivityForResult() as "activity 2" can't be started from "activity 1". Any suggestion would be much appreciated Thank you very much guys, regards.

For example lets say i click a button, and then it adds a second activity to the current activity. And the second activity only covers a small place at the bottom of my current activity.

I created an application which enables the user to set whether he wants to receive notification while the application runs in background mode. If the notifications are enabled an activity should be started (the dialog should appear on the screen).
I tried to enabled it the following way:
CODE:...........
This is the method from main activity. When onPause() is executed isRunningInBackground is set true.
When I tried to debug it when the main application was running in the background the line
startActivity(intent) had no effect (the activity didn't appear).
Does anyone know how to midify the logic in order to start an activity from the main activity when the main activity is running in the background (after onPause() is called)?

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.
