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?

View 2 Replies View RelatedI 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?
View 2 Replies View RelatedThe 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.

View 1 Replies View RelatedI have tried to understand for the past 2 days what is the best approach to making the value from a variable sitting in activity A (in my case, the int position used in OnListItemClick / OnItemSelectedListener) available in another activity B (which of course sits in another class). There may be the option to write the result of the OnListItemClick int position into a small SQLite DB - but that seems to be total overkill.
Anybody could pls share the best approach with me?
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?

View 2 Replies View RelatedI 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.
How do I close a whole hierarchy of activities and show a new activity not present in the current task?
Context
Consider a FTP browser that resumes the previous session on launch. Each folder is displayed in its own activity. When I click on a folder, a new activity is started for the folder. If I press the back button, the app returns to the previous activity, which corresponds to the the parent folder.
I can logoff from the menu at any time. Logging off should bring me to the login activity (not present the current task when the app has resumed the session), and close all the other activities. How can I do this?
From what I've read, if the activity were in the current task I could use FLAG_ACTIVITY_CLEAR_TOP in the intent, but this is not my case.
startActivity() displays the new Activity on top of the current one. But how to display it underneath instead? BTW, I'm starting an Activity from another application, if that makes a difference.
View 5 Replies View RelatedIs copying the reference to the object and not the value of the object. Meaning, when I modify pos.top or pos.bottom, the original object gets modified. I'm guessing I am missing a concept of pass object by reference vs value here which I thought I understood. What is the fix here? Is it a problem with how I defined my custom class?

I m doing some task with following code,
I want to access inner class variable from outer class method.
class Outer extends Activity
{private Handler mHandler = new Handler();
StopTheThread()
{mHandler.removeCallbacks(mUpdateTimeTask);//
This is the what I want to do:
} class Inner
{ final Runnable mUpdateTask = new = new Runnable() {
public void run() {
//Some Code Goes Here
} };
InnerClassMethod()
{ mHandler.removeCallbacks(mUpdateTimeTask);//
This statement working fine here. Here mUpdateTask is inner class variable which is not accessible from outer class.
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)?
I have Serviceļ¼Sometimes current run Activity work in background I don't want to know. I want to know current work interface Activity name?
View 3 Replies View RelatedI'm trying to figure out the correct way to create an AsyncTask to retrieve some data from the internet and then to take that data and bundle it up in an Intent and pass it to a new activity(A list display). So in the first activity I just have an EditText and Button. In the event of an OnClick the task should be called and when it is finished the data should be bundled inside an Intent and passed to the next Activity. The problem is when I take the results from onPostExecute and set them to an instance variable of the main activity, that instance variable is still null when the task is complete. Here is the barebones version of the code:
CODE:...........
When I debug the application I see onPostExecute does contain a valid PlacesList full of results, so why is the instance variable places set to null after the task is executed? I am going about "returning data" from an AsyncTask incorrectly?
