Dear stackies, before publishing a new app on the market, on which devices would you suggest to check whether it runs fine or not? What are your experiences? How do you handle this? Are there some empirical values, for example, do applications that run smoothly on a HTC Desire behave similar on all HTC devices? Are there some devices o...
I am trying to compile and run the Android Camera for sdk 1.6 (also called API level 4 or Donut release). While there is no minSdkVersion in the AndroidManifest, it clearly does not run on a donut device. In fact, if compiled with sdk 2.2 the camera will crash with a NoSuchMethodError execption on an avd or a G1 with sdk 1.6. I tried...
I am optimizing our database for Android SQLite. The data is simple, 3 ints (Country, State, City) The data is stored in order by Country, State and City. If I create an index on the three fields in ASC, would that be the most efficient given that we "READ-ONLY" the data 100% of the time by the 3 fields? ...
I have observed that by default the wifi adaptor goes into (power saving mode) PSM mode. When Certain applications such as youtube appear to buffer video, the adaptor leaves PSM mode into CAM state or full power mode. Once the buffering is done, the wifi adaptor goes back into PSM mode. I have observed this behavior with other appl...
I need to update my AppWidget when my main activity pauses. I tried using the following code in my main activity's onPause(): super.onPause(); AppWidgetManager manager = AppWidgetManager.getInstance(this); int[] a = manager.getAppWidgetIds(new ComponentName(this, "WidgetProvider")); new WidgetProvider().onUpdate(this, manager, a); Wh...
I don't know much about Java or Android development, so I'm digging into it myself. But I noticed that if I open sample code that came with my new 2.2 SDK, Eclipse by default will contain errors until I open up specific files. Is this normal for IDEs? Or is there something I'm missing? I am having to use Eclipse 3.5.2 since Google sa...

I would think this should be a relatively easy question to answer, but I'm brand new to android development and so not sure where else to turn. I have a simple layout (relative currently) for my main Activity. I want to create an object (a card for a card game) that will have all of the necessary properties for that card (value, suit, ...
I'm wondering how I can create a custom pop-up like the one in the screenshot below (borrowed from the Swype keyboard), where I can have a couple of buttons, which each commit a string to the currently "connected" TextView (via a InputConnection). Please note: this is an InputMethodService and not an ordinary Activity. I already tried ...
This code doesn't work: URL url = new URL( xmlPath ); InputSource input = new InputSource( url.openStream() ); all the time, resulting in an UnknownHostException, even when the host exists, has been hit successfully using the same code if from a different development host (machine), and also from a browser. I'm probably out...

When I press and hold the screen, select Wallpapers and then select Live Wallpapers, my live wallpaper has what looks like a default icon with the name of my live wallpaper overlaid. How do I set this icon? My manifest file has an application icon specified as @...

I have a ListView with different layouts for different items. Some items are separators. Some items are different because they hold different kinds of data, etc. I want to implement ViewHolders to speed up the getView process, but I'm not quite sure how to go about it. Different layouts have different pieces of data (which makes nami...
Hi, I would like to know if the WebView browser understands an embedded HTML media object and plays in the media player or do we have to start a Media Player activity to play the media content? Thanks, Sana. ...
That idiot being me. I've read a bit about it at http://oauth.net/ , it's "a simple way to publish and interact with protected data" apparently. I think it's exactly what I need to provide a secure way of accessing data from an android/iphone app via a REST web service, but I can't work out exactly what it is. So, put simply, what exa...
I've started seeing some apps that offer to read/write data to the internal phone memory (like Super KO Boxing 2, which offers to save a whopping 52MB to the phone memory). I suppose this is because newer Android devices have a lot of internal storage, as opposed to my devices, which have very little. I would like to support internal s...

Our Android app loads RSS feeds for news and blog sites and displays the stories in a webview. Whenever a story has a YouTube video, the video doesn't show up and it doesn't play (the object is there, but it's just whitespace & nothing happens when you tap it) Surely, since Google owns both Android and YouTube there's simple way to all...
