Android :: Way To Pass Bundle To Activity Set As Singletask?

Apr 22, 2010

So I have a MapActivity that runs an asynchtask that occasionally updates what exactly it's displaying on the map (via a string). I originally pass this string in from the intent when the activity is first created. And then if you click on one of the drawables on the map, it opens a new activity, which can then create a new mapview (same class) with a different string setting. The problem I have is that I only want one instance of the mapview to be running at once. Thus I set android:launchmode="singletask" in the manifest. This works in that it brings the mapactivity to the front, but is there any way to send it a new intent bundle to get a new setting for the string it needs? I tried regetting the extras from the bundle, but it seems to retain the old bundle, not the new intent that was passed to it. I'm not sure I want to do startActivityForResult because the 2nd activity may or may not want to update the original activity. I hope that made sense. I can post code if necessary, but I think that should explain my situation.

I have an application where I navigate from Activity A to Activity B and back to A and then B. I want to resume the activity B (which has a Bundle passed to it ) from Activity A.

Android :: Change Intent Bundle Data Before Activity Recreated After Orientation Change

Jul 30, 2009

I have a notification that starts my activity and passes a messages using the intent's putExtra() function. The message is then displayed to the user in the activity's onCreate function. When the application is restarted due to a orientation change, the message is shown again as it is still in the intent's bundled data.
How can I remove the extra data?

I tried the following:

Bundle bundle = getIntent().getExtras();
if (bundle.getBoolean("showMessage")) {
// ... show message that is in bundle.getString("message")
// remove message
bundle.remove("showMessage");
}

But the message will still be shown after the orientation changed, seems like the intent used is not the one I changed, but the original one. The only workaround I found is to save the showMessage additionally in onSaveInstanceState(). Is there another way? Or is this the way to go?

Android :: Correctly Manage Activity Stack In This Instance?

May 28, 2009

I'm working to finish a small application, but I'm having problems seeing what combination of activity attributes and intent flags I need to achieve my intended application design. Trying my best not to describe the app in minute detail, here's the basic operation (I've supplied screenshots in the hope it makes sense easily): Users have a garden which contains flowers (GardenActivity).

http://www.tomgibara.com/images/daisy/garden/hut_screen.jpg

They can tap on a garden to see details of flowers (FlowerActivity)

http://www.tomgibara.com/images/daisy/garden/flower_screen.jpg

When flowers are fully grown a notification provided, tapping on the notification displays the garden containing the flower.

http://www.tomgibara.com/images/daisy/garden/notify_screen.jpg

Users can also use the GardenActivity as a picker to choose flowers to "exhibit" (ConfigureActivity)

http://www.tomgibara.com/images/daisy/garden/planting_screen.jpg

I want the app to operate so that if the user already has a GardenActivity somewhere in the stack (whether it's at the top, or underneath a FlowerActivity) the notification will alert the user by bringing that activity to the front (clearing any FlowerActivity that may be above it). I've tried using the FLAG_ACTIVITY_NEW_TASK | FLAG_ACTIVITY_CLEAR_TOP combination (without changing any activity launch modes) on the notification's pending intent, but it still launches a new GardenActivity, even if one is already available.

I've also tried using android:launchMode="singleTask" on GardenActivity. The notifications then seem to work correctly, but it prevents GardenActivity from returning any result back to ConfigureActivity.

Android :: Activity Still Lagging When Run Stuff In Service And Handler.post Method / Do This Correctly?

Nov 18, 2010

I'm confused why is my activity still lagging, I use remote service that has few methods and each has its own work like download stuff, process data, compare stuff, etc... It will run in background and update data at selected intervals and notify user of changes over notify system.

The reason why remote service, because I will eventually add a widget, and service needs to stay running even if android kills the activity, so I unbind it on each onPause().
But as far I understand that part doesn't cause my issue.

But back to my problem... so my is Activity still lagging when I run stuff in service and handler.post method.

here is the code...

Also I wanted to add progressDialog to be updated in updateLayer(...) through Activity is a listener to this service, but thats not working well. Whats the best way to update progressDialog? Ever listener, handler, intent, or what?

So how do I do this correctly?

Android : Multiple Handlers Design In An Activity Failed

May 14, 2010

This question is related to an existing question I asked. I though I'll ask a new question instead of replying back to the other question. Cannot "comment" on my previous question because of a word limit. Marc wrote - I've more than one Handlers in an Activity." Why? If you do not want a complicated handleMessage() method, then use post() (on Handler or View) to break the logic up into individual Runnable. Multiple Handlers makes me nervous. I'm new to Android. Is having multiple handlers in a single activity a bad design ?

I'm new to Android.My question is - is having multiple handlers in a single activity a bad design ? Here is the sketch of my current implementation. I've a mapActivity that creates a data thread (a UDP socket that listens for data).

My first handler is responsible for sending data from the data thread to the activity. On the map I've a bunch of "dynamic" markers that are refreshed frequently. Some of these markers are video markers i.e., if the user clicks a video marker, I add a ViewView that extends a android.opengl.GLSurfaceView to my map activity and display video on this new vide.

I use my second handler to send information about the marker that the user tapped on ItemizedOverlay onTap(int index) method.The user can close the video view by tapping on the video view. I use my third handler for this. I would appreciate if people can tell me what's wrong with this approach and suggest better ways to implement this.

Android :: Child Activity Does Not "finish()" Correctly

Jul 8, 2010

I have a ListActivity I display from a parent activity. When the user selects the desired item from the list it supposed to return to the parent activity. Only when I call finish, the app goes away (doesn't quit) and displays the Android Home page. If I debug, the application doesn't die, it just sits on an MessageQueue.Wait().

I have a break point right before the finish() call and one in the first line of the OnActivityResult. When I press continue from the first, I never see the second on in onActivityResult.

I have other child activities in my app that don't display this problem. However this is the only ListActivity I have that I am trying to return from. I do call finish from onListItemClick. I'm wondering if that is not allowed since that is responding to a view event. However if I don't do it here, how can I get back to the parent activity. Below is the code snippet of my finish method.

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

Android :: Java Datetime Values From String To Long To String

Oct 1, 2010

In Android, capturing date from datepicker and storing as string in sqlite. Sorting by date doesn't work because they're strings (unless I'm doing it wrong.I've googled this issue for ~5 days, and it looks like there should be a way to capture the date from the date picker, convert it to a Long, store it in sqlite as a Long, select and sort on the Long date value, then convert the Long back to a "mm/dd/yyyy" string for display. I've tried various combinations of parse statements, Date, FormatDate, etc. with no luck at all.On activity start, get today's date and display it in button which calls the datepicker.Capture new date from datepicker (if one is entered), save it as a long to sqlite.On opening an activity showing a listview of records, select from sqlite with orderby on date (Long), convert Long to "mm/dd/yyyy" string for display in ListView.
