• Android: how to obtain AssetManager without reference to Context?

  - by ab11

  I have a Class that needs to obtain a reference to it's application's AssetManager. This class does not extend any sort of android UI class, so it doesn't have a getContext() method, or anything similar. Is there some sort of static Context.getCurrentApplicationContext() type of method? To clarify: my class is intended to be used like a library, for other applications. It has no associated AndroidManifest.xml or control over the context which is calling it.

• Would it make sense to have a separate Scala library in Android market?

  - by soc

  As far as I understand it is necessary for people using Scala for Android applications to bundle the Scala classes they used with their application. Considering this adds hundreds of kilobytes to each Scala app redundantly, would it be possible to build a Scala library which can be delivered over the market, so app writers can just depend on that library instead of bundling it themselves?

• .NET applications sometimes doesn’t work on Windows CE

  - by KZChris

  Hi, I write applications for Windowe ME and CE in C# .NET 2.0. Sometimes I’ve got problems because applications don’t work on some navigation devices. On Windowe ME it is not problem because .NET can be installed from a cab, but on most Windows CE devices it is impossible because after soft reset all changes disappear. I found out that in most difficult cases good solution is to put all dll-s belonging to .NET installation cab in the folder where the application runs and everything work well. However there are some devices for example Navroad NR460 (Windows CE 5.0) on which none of .NET applications work (it is funny because previous and next version of that navigation works well). I didn’t found on this device cgacutil.exe program. Is this possible to force the device to run any .NET application without installing the Windows again? What should I try to do to check if running .NET a applications is possible? What conditions should be fulfilled to run easiest application written even in .NET 1.0
