[android-developers] Re: AsyncTask, Runnable Thread, ???
AsyncTask is designed to run with Android API (activity, service, etc...) so that would be my preferred choice if I was using it within an activity say. The class has a well designed lifecycle and makes code more readable than the thread/handler idiom.

[android-developers] Re: Honeycomb SDK
Good point spiral123, it would be in line with android openness to make this sort of information available to developers as early as possible, something that would greatly benefit the platform, no doubt. However this wasn't the case (and still isn't) with Google TV. Let's hope that with the change of CEO comes a return to traditions for Google.

[android-developers] Re: ContentProvider blank screen
Thanks for your prompt answer Brion, Managed to put the time consuming portion of the code in an AsyncTask inside the ContentProvider. It seems to be doing the job, my main activity is not hanging. Now I have two questions which I need to answer: (1) Is this a correct usage of the API? i.e. is it ok to use an AsyncTask inside the ContentProvider? (2) Is there a way for my main activity to get notification when the ContentProvider has finished initialising? Input from the Android dev team would be highly appreciated.

[android-developers] ContentProvider blank screen
Hi, My app has one activity and one ContentProvider, the activity is simple in that it's just a splash screen at the moment with no other logic in it (I do intend to have more activities in the app). The ContentProvider uses SQLite as a back end and loads some static data from files on first install, a slow process due to file sizes and database initialisation. My problem is that I want the activity to show up as soon as the install starts and maybe display a progress bar or dialog to show the user progress about the install. At the moment I get a blank (white) screen while the ContentProvider is initialising the data which takes quite a long time and I get "Activity idle timeout for history record" warning in LogCat. My splash screen only shows when the ContentProvider is done, from the app standpoint this is undesirable behaviour. One potential solutions would be to manually start the provider via an AsyncTask but I have a feeling that this is a bad approach due to the fact that if the activity is interupted and restarted while the install is underway and a new AsyncTast is created through the activity's onCreate() then I'll have worst problems on my hands. Is there a way to start the content provider in the background and display my splash screen activity straight after the app is started? Note that this problem is only an issue on first install.

[android-developers] Re: Chilling news: Oracle sues Google over Android
There's far too much written on Java vs whatever other language people think is better. The bottom line is java has hit the right balance between performance/ease of coding/maintenance/scalability and what not, and that's why there's overwhelming adoption for it out there. This also allowed for a huge number of opensource initiatives to flourish. These facts combined make it the best overall choice for the vast majority of projects, corporate or otherwise, and I congratulate Google for choosing java as the primary language for app development, which in turn is allowing our ecosystem to grow at an unprecedented pace (while keeping the competition at bay). Now! can anyone (Google guys?) enlighten us on what's the lawsuit about?

[android-developers] Stopping GPS inside an activity
Hi, Currently working on a simple app to allow users to find various things around them. When the activity that shows the Google map is active I can see the GPS icon on the status bar, which is normal. But I need to be able to stop the GPS hardware when my user navigates away from the activity, and switch the GPS back on when the activity is shown. Is there a simple way to stop GPS when a user navigate away from an activity? I have tried the LocationManager's removeUpdates() but this doesn't actually stop the GPS (the icon is still flashing on the status bar and draining the battery). What I'm looking for is a simple way to programatically stop the GPS hardware.
