xamarin.android

问题 I'm looking for a workaround for the following problem. Given a class hierarchy in Java: public interface Bar<T> { getValue<T>(); } public abstract class BarImpl<T> implements Bar<T> { } public class Foo extends BarImpl<Double> { @override public Double getValue() { // .. } } Xamarin.Android generates wrappers as follows: // Now in C# land public interface Bar { // Xamarin.Android omits T Value { get; } } public partial abstract class BarImpl : Bar { // Xamarin.Android omits abstract T Value

问题 I am using Visual Studio 2010 to experiment with Monodroid in C#. I'm aware that Android applications can be run on Windows using the emulator. Is it possible to use the Android API in a Windows console application? I would like to use the Android speech recognizer without actually running it in an emulator on Windows. 回答1: No-- Android API is (partly) based on firmware designed to run on a particular hardware platform-- The emulator emulates the platform at the hardware level, which is why

问题 In a classic XNA application this value is set through the application properties. By default this value is set to HiDef , at least on the machine I am currently using. But it has to be set to Reach to run. My problem is that I did not find any way to effectively change this value using monogame. The property window is obviously not the same as with XNA and I did not find any config values. Changing the value in the code, in the Game constructor or the LoadContent method does not solve my

问题 After some experiments I compiled Mono 4.4.2 for Android x86_64 (Marshmallow) using Android NDK r13b. I had to do some tricks, but after all I had these folders in my build directory: bin etc include lib share The bin folder looks like : The lib folder is: The lib folder contains only unmanaged libs, e.g. the 'mono' subfolder doesn't contain managed BCL for each version of the framework, I couldn't figure out how to tell to 'configure' script to do this. So I've compiled the same version of

问题 Similar question to this one : How can I detect the Android runtime (Dalvik or ART)? How to do it in Xamarin.Android (MonoDroid), since I dont have java reflection here? Since ART is not working on xamarin yet, I would like to detect it and show user some friendly message instead on app crash at least. Thanks. 回答1: Seems to work on the emulator, don't know what happens with actual device until it gets some charge: [Activity (Label = "RuntimeActivity", MainLauncher = true)] public class

问题 I am testing out Xamarin.Android via Visual Studio 2010. My Xamarin.Android VS2010 Solution contains two projects: The Android project and a project (I'll call it MyProject for this post) that does all the business logic for the demo app that I'm making - The Android project references the MyProject project/assembly). When I run the appliation, I am receiving an exception error in MyProject and, so, I would like to step into MyProject and debug the problem. However, when I debug, VS2010 is

问题 I want to trace the whole movement of a finger that started by touching my ImageView. I found that GenericMotion event should be the correct one to use. What am I supposed to do (or to avoid) to get Actions Down, Move and Up in GenericMotion event? I get only HoverEnter, HoverMove and HoverExit actions, even if I start with touching the center of my ImageView. Android: OnTouch, MotionEvent.ACTION_MOVE is not recognized? Here I learned that without handling Down action I can't get the
