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..?

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?

Android :: Finish Activity Not Started From Current Activity

May 1, 2010

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.

Android :: Want To Get Current Focus View Object In Service?

Nov 18, 2010

I want to get the current focus view in my Service to check the view is a EditText and append some texts in it (for all EditTexts, not only in my application).

I found some methods to do this, like Activity.getCurrentFocus() and Windows.getCurrentFocus(). But these methods are used in a Activity.

How can I use these methods in a Service? Or is there another way to do?

Android :: Determining Current Foreground Application From Background Task Or Service

Jan 30, 2010

I wish to have one application that runs in the background, which knows when any of the built-in applications (messaging, contacts, etc) is running. So my questions are: How I should run my application in the background. How my background application can know what the application currently running in the foreground is.

Best Way To Get Current Locations From Background Service

Apr 8, 2014

I have a Service that I am running in the background every minute. It's an IntentService and I start it like this:

Code:
Intent i = new Intent(context, GPSTracker.class);
PendingIntent pi = PendingIntent.getService(context, 0, i, 0);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
[code]...

That works, my Service is being run every minute (give or take a couple seconds for some reason) whether the app is up, closed, the phone is sleeping, whatever. how I should be getting the current location from this Service. I'm attempting to use LocationListener and a mix of getLastKnownLocation and hoping onLocationChanged will be called.

I think my problem is, onLocationChanged is barely getting called. Everytime the service runs and I do getLastKnownLocation I send a message to my database to check, I send a different message everytime onLocationChanged is called. I went to the store and back and getLastKnownLocation was called a few times, but onLocationChanged was only called once and it was incorrect. getLastKnownLocation always seems to be incorrect to.

Code:
protected void onHandleIntent(Intent intent) {
Log.i(TAG, "In onHandleIntent!");
Location currentLocation = getLocation(this);
if(currentLocation == null) {
saveLocation(-8.0, -8.0, "nothing", "nothing", "nothing");
[code]...

Android :: Phone Won't Save Current State Of An Activity / Way To Do

Nov 17, 2010

I am trying to save some values in the onSaveInstanceState(Bundle) method of my activty by following the example here: How do I save an Android application's state?

But it doesnt seem to load it from the Oncreate(). the bundle object is always null but whenever i call another activity, it does indeed go into the onSaveInstanceState method to save my values.

Now i read that question i just posted and someone noted how they could not get it to work in an emulator? unfortunately that is all im working on. On an emulator and cant test the app on the device as i have no device available to me right now And the web services i am interacting with are in a local VM on my work machine that cannot be accesses remotely at the moment.

My question is, is it true that saved bundles dont work on emulators? I also noticed how when i do dismiss or bring up a new activity , the activity calles onPause and then onStop. when i bring back the same activty, it goes straight to onCreate?

now according to the docs here http://developer.android.com/guide/topics/fundamentals.html#actlife That is correct in terms of what the lifecycle diagram shows but if you read below that diagram on the onStop() section it says the next step it goes into is either onRestart() or onDestroy()? no mention of onCreate? Type on the docs?

Anyways here is my onSaveInstanceState() and onCreate() both in the same activity: code...
