Android : Bringing Activity To Foreground Via The Call Button (Green Key)

Feb 4, 2010

I currently have an application that naturally gets pushed to the background when the home key is pressed.

The activity losses focus but continues running in the background.

So I want to know is it possible to bring the application back to the foreground when the user presses the green key (call button) on the device?

Android : Start An Activity WITHOUT It Becoming The Foreground One?

Apr 22, 2010

Is there a way to call startActivity(Intent) without the newly started activity displacing the current one as the active, foreground activity?

If not purely so, are there near approximation to this effect that can be done, such as mimicking a back keypress event right after calling startActivity()? If so, which means is preferred?

Android :: Notified When Foreground (top) Activity (application) Changes

Oct 6, 2010

I want to write a service for Android platform that is notified when the current foreground activity changes. Basically the service should do some tasks only when the top activity changes. Is there any way to subscribe and to be notified when this kind of event occurs? Or there is no possibility and the service should poll from time to time the list of running activities and to check what is the foreground activity ?Not preferable solution...

Android : Inform Activity From A BroadcastReceiver ONLY If It Is In The Foreground

Feb 17, 2010

Maybe it's easy, but I couldn't really figure this out right so far... I got a BroadcastReceiver waiting to get triggered by the AlarmMangager - this works fine.

Now: because the event, if it occurs, needs to refresh some elements on screen of the main Activity, I would like to send an Intent from that background BroadcastReceiver to my Activity - but only if it is currently in the foreground, aka active.

If it is not running or not visible, I don't care - and the last thing I want to do is start the Activity by my intent! I handle repainting of the views in my onResume method, so I don't care at all.

EDIT: my BroadcastReceiver is waiting for alarms that must be notified to the user. So, it must be there and declared in the manifest. The problem is: it will have to decide whether the mentioned Activity is currently up in front or not.

Android : How To Bring An Activity To Foreground (top Of Stack)?

Feb 9, 2010

I defined an activity ExampleActivity.

When my application was launched, an instance of this activity was created, say it is A. When user clicked a button in A, another instance of ExampleActivity, B was created. Now the task stack is B, A, with B at the top. Then, user clicked a button on B, another instance of ExampleActivity, and C was created. Now the task stack is C, B, A, with C at the top.

Now, when user click a button on C, I want the application to bring A to the foreground, i.e. make A to be at the top of task stack, A, C, B.

Android : Webview - OnCreate Always Get Called When Activity Comes To Foreground

Mar 29, 2009

I launch my TestWebView activity. After my web page is loaded, I put the app in the background by pressing the Home key. Then I bring the TestWebActivity back to the foreground. Unexpectedly, TestWebView's onCreate() is called when I bring the activity to the foreground. But onDestroy is never called. This same thing happens every time I tested. It appears the old TestWebView was not completely killed so there are possibly duplicate web clients running.

Android : Create A Surface Object Without A Foreground Activity

Jul 6, 2010

I have a function that needs a Surface object to work. I'd like to be able to call that function from a background Service without starting a foreground Activity. Every Surface source in the API that I can see, though, requires a View that's laid out before the Surface becomes available. Are there other ways to create a Surface that I am missing, and can you point me to them?

Android : Send Touch Events To Foreground Activity

Jul 21, 2010

I'm trying to figure out a way to send touch events to the foreground activity. Essentially I want to write something that allows me to run it from the shell and just say "I touched this co-ordinate", so that I can automate some UI tasks for testing. Essentially what Monkey does, but application agnostic.

I think that android.view.MotionEvent holds the key, but I'm not sure how to run something without view so that I don't interfere with what is on the screen. Perhaps with a service, but I'm unclear how that would work.

Android :: Recent Apps Change In 2.2 / Brings Main Activity To Foreground

Jul 24, 2010

The recent apps display seems to function quite differently from earlier versions on 2.2. Try the following for instance: 1) Open an app 2) Click on something that takes you to another activity in the same app 3) Press the home button 4) Press and hold the home button to get the recent list of apps - select the app you chose in step 1 5) You'll be taken to whatever activity in that app is specified as the main/launcher Activity, rather than the Activity on top of the stack (as it was previously) It makes it appear to the user that the application has exited when the home screen button was pressed. I don't have my app set to clear history on launch or anything like that, and I can replicate it on the emulator and with any app on my device (Contacts, Gmail, Engadget etc) Anyone else notice this? Anyone know any reason for the changes? I must admit I quite dislike the new method.

Android : By Clicking On My App's Launcher Icon, Bring My App To Foreground And Not Launch New Activity

Feb 28, 2010

My app has 2 activities - A and B. From homescreen I launch A, from A I launch B. The activity stack looks like this: A-B. Now I press HOME button, and from homescreen click again on my app icon, which launches A and adds it on top of the activity stack, which now looks like this: A-B-A. But I just want to bring my application to foreground, is that possible in Android?

Android : Multiple Activity Instances Launched By Same Intent. Bring One Uniquely To Foreground?

Nov 12, 2010

I'm struggling with my app that launches multiple instances of the same Activity using the same intent. My main activity is of class type A and it does a startActivity() of two children that are of the same class type B. So we have B1 and B2 launched. If B1 and B2 are both paused (by pushing back button and making sure finish() is not invoked on them so they are truly paused), how can A uniquely bring either B1 or B2 to the foreground again? I do want to launch a new B activity. I want to uniquely bring B1 or B2 to the foreground.

so both B1 and B2 were created like this... Intent intent = new Intent(context, B.class); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent);

Now I want A to bring B1 (or B2) to the foreground/front so I use the below code, but how do I distinguish B1 or B2 when starting the activity? This only brings the last instance of B that was on top to the foreground.

Intent intent = new Intent(context, B.class); intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); startActivity(intent);

I've tried keeping around references to B1 and B2 and doing something like this, but this also only goes to the last instance of activity class B that was on top...

Intent intent = new Intent(B1context, B.class); intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); B1context.startActivity(intent);

I even tried this, but it still doesnt get me my unique B1 or B2... Intent intent = B1.getIntent(); // i.e. the original intent that started me startActivity(intent); // still only brings to front the last B that was on top.

Android :: How To Control Activity Flow - Back Button Versus Home Button

Sep 2, 2010

I have 3 activities in my app: Activity1 -> Activity2 -> Activity3. Inside Activity3, if the user presses Back, I would like to return to Activity2. In Activity3's onPause event, I added a finish() statement. That's probably not even necessary, but I wanted to make sure this Activity gets cleaned up. This works fine.
However, while in Activity3, if the user presses Home or starts a new app (through notification bar or some other means), I want both Activity3 and Activity2 to finish. If the user returns to this app, he should resume with Activity1.

I have figured out how to do one or the other, but I can't figure out how to handle both cases, if it's even possible. Can I trap the "Back" button in Activity3 and send a message back to Activity2 telling it not to finish()? It seems like the Activities follow the same lifecycle flow (Pause, Stop) regardless of what you do to send them to the background. Just to answer the question of why I want this behavior, imagine that Activity1 is a login screen, Activity2 is a selection screen, and Activity3 is a content screen. If I press Back from the content page, I want to be able to make a new selection. If I exit via any other means (Home, notification bar), I want the user to be "logged out".

Android :: Starting Second Activity From Main Activity On Button Click

Dec 4, 2009

Need an example of how to create/start a new activity from the main activity. I have a button click event on the main layout. Originally I just used setContentView(R.layout.secondactivity); which brings up the layout but I don't think that is correct since the secondactivity class is not instantiated at this point yet. I have looked for such an example and can not find one.
