Android :: Blocking Current Activity / Screen Till Current Task Is Complete

May 13, 2010

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.

Android :: Close Activity Hierarchy In Droid / Show New Not Present In Current Task?

Sep 26, 2010

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.

Android :: ActivityManager - Warning -Activity Not Started Its Current Task Has Been Brought To The Front

Aug 25, 2010

CODE:..........

Here is the code where the problem lies....

It doesn't give me an error it says exactly this when I run the android emulator

"[2010-08-25 09:12:42 - doppler_test] ActivityManager: Warning: Activity not started, its current task has been brought to the front"

What I think this means is that the intent of the bluetooth function and the button intent is only operation on a hierarchy system. What I mean by this is that if I were to move the button opperator above the Bluetooth stuff the button will work, but currently when the app is run Bluetooth works but when I press the search button nothing happens.

What else may be helpful is my XML code for the button so here it is......

Android :: How To Detect If Current Stack Of Activities (task) Moves To Background?

Jul 23, 2010

The official documentation describes tasks as follows: All the activities in a task move together as a unit. The entire task (the entire activity stack) can be brought to the foreground or sent to the background. Suppose, for instance, that the current task has four activities in its stack three under the current activity. The user presses the HOME key, goes to the application launcher, and selects a new application (actually, a new task). The current task goes into the background and the root activity for the new task is displayed. Then, after a short period, the user goes back to the home screen and again selects the previous application (the previous task). That task, with all four activities in the stack, comes forward. Is there a way to programmatically detect when the task of the current Activity moves into and out of the background? I would like to know when the user has switched switched to another application, vs. when the user navigated to another Activity in the current app.

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.

Android :: Click On Status Bar Notification Switch To Task In Current State?

Aug 16, 2009

My applications carries on processing when the user presses the home key, and generates status bar notifications if something happens the user requested to be notified about.

If a user holds the home key and then selects the application, it is restored in its correct state with the activity on top that showed when the user left.

However, since the intent that is associated with the status bar notification is FLAG_ACTIVITY_NEW_TASK and I put in the class name of the activity that launched the application (I assume this is what I must do?), the launcher activity is started when the notification is "clicked". I can then switch the application back to the current activity by starting that "active" activity again, but then I seem to have two instances of the activity in memory, since I have to press back twice to leave it. And I suspect my activity stack is then messed up as well.

I have set the launcher activity to be singleTask, but that only helped a bit. From my reading I thought this would just give the task focus if the launcher activity is not on top, but instead it gives the launcher activity the focus.

Is there a way for a notification click to work more like the task switcher provided by long pressing the home button?

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 :: 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 :: 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...
