I am having some design techniques about How shall I schedule a code to retrieve the weather info? Should I use alarms to retrieve the weather each 10 minutes? And do I need to run a service for this? Or just put the code in the Broadcastreceiver and start when the alarm fired? ...

I am trying to use jdotnetservices (http://www.jdotnetservices.com/), which is a java SDK for Windows Azure AppFabric, in an Android application. I have had to make some tweaks but only minor ones because jdotnetservices is written to target Java 1.6 and Android uses 1.5. I can get it to compile and run OK but I'm getting errors when I ...
The main Activity I use in my Android application uses a fair amount of memory, meaning that on a less powerful phone, it is susceptible to being killed off when not at the front. Normally this is fine, but it also happens when I am still inside my application, but have a different activity at the top of the stack (such as a preference a...
Bug I have a weird bug in my piano app. Sometimes keys (and thus notes) hang. I did a lot of debugging and narrowed it down to what looks like androids inaccuracy of motion event handling: DEBUG/(2091): ACTION_DOWN A4 DEBUG/(2091): KeyDown: A4 DEBUG/(2091): ACTION_MOVE A4 => A4 DEBUG/(2091): ACTION_MOVE ignoring DEBUG/(2091): ACTI...
I have released an app (World Time) with initial database. Now i want to update the app with a database upgrade. I have put in the upgrade code in OnUpgrade() and checking for the newVersion. But it was not being called in my local testing... So i put in the debug statement to get the database version and it is zero . Any idea why it ...
So, I noticed that I can organize apps into folders (HTC Incredible). However these folders are fairly limited in their capabilities. I want to implement an activity that extends the "base" folder activity (at the very least I want to add the ability to rearrange items in folders), but I can't figure out the class name... So, what's the ...
I have an Android Developer Phone with Android 1.6 installed, sometimes it will take 30 seconds for the home screen to appear after a call or exiting from an application. Why is my phone so slow? Should I replace the memory card? Also, when is the 2.0 coming out for the ADP2? How do I install it? ...
I've been trying to experiment with developing Android applications with Scala. I've gotten to the point where I can get the app to compile, but there are no helper functions for things like: button.setOnClickListener( () => { text.setText("test") }) (I'm talking about the closure there) I see lots of references to scala-android...
So I've been looking at code from various parts of the Android git, but when I try to load and compile many of them (camera, media player, etc) they reference classes and parts of the SDK that just aren't available even with my SDK version updated to 2.2. (for example the bitmap config option inNativeAlloc) Is there a reason that these...
I'm currently working on a webservice-client for Android. I'm using a Java client library which provides an abstraction for interaction with the service. The client library works on normal machines. However, when I use the classes in my Android project, some calls don't return a result on Android, the background-service stops working at ...
Note: The VM mentioned in here is not like in VMWare or VirtualBox, it is more like Java Virtual Machine (JVM), (as well as Python and Ruby). That is, the fact that objective c is an interpreted language, should make it easier. For a long time I wondered if the following idea worth a nickel or just a waste of time and energy. I am wi...
What's the best way to create a reusable loading screen in Android? The loading screen should have a background image and a loading indicator. Should I use a separate activity? ...
I would like to make a LinearLayout that was created from xml invisible, and another LinearLayout visible to replace it. The replacement layout starts out as invisible. When I make the originally visible layout invisible, it still leaves space for it on the screen. How can I refresh the screen so that space is gone? ...

Is it possible to change the orientation of an ImageView to be always PORTRAIT, while the other views in the activity can rotate? Since images don't always look good when rotated... Thanks Chris ...
I have a use-case for a vertical 1x4 home screen widget on android. The supported size is 4x1 ie horizontal. Does anyone know if the vertical version can be implemented? I realize changing screen orientation would scrunch the widget together, which I'm fine with. Even better would be if there was an equivalent to "overflow hidden" in cs...
Thanks, EDIT/// Converting the outcome to radians gives me a lat of 5.6xxxxxxxxxxxxxx .I have a feeling this bug has something to do with conversions but its not THAT simple. The equation is correct, it just.. outputs wrong.. ...
Hi! I need to implement HorizontalScrollView which is scrolled to predefined positions (similar to Home behaviour). It works with slow gestures, but does not work with neither flings nor arrow key press. I hooked to View.onScrollChanged() and it is called when scrolling happened, but I can't determine when scrolling animation ends. In...
I have quite a complicated ListView. Each item looks something like this: > LinearLayout (vertical) > LinearLayout (horizontal) > include (horizontal LinearLayout with two TextViews) > include (ditto) > include (ditto) > TextView > HorizontalScrollView (this guy is my problem) > LinearLayout (horizontal) In my ac...
