Public class MainActivity : AppCompatActivity So, in all the files using the Yoctopuce library, we must add the following code: When generating the binding library, Xamarin automatically renames some functions and some properties to adapt them to C# conventions.įirst, the java packagename is transformed into the namespace. Then we can simply use the Yoctopuce library directly from the C# code. The Reference Manager window enables us to add the binding library In the "Reference manager" window, use the "Browse." button, select the YoctoAPIBindings.dll file, and click "OK". We can do so with a right-click on the "References" node in the "Solution Explorer" panel or with the menu "Project" -> "Add Reference.". Then, we must add a reference on the YoctoAPIBindings.dll file that we just now compiled. The second project is of type Android App (Xamarin) In our case, we are going to call it "DemoApp" and we start from a simple project (Blank App). To do so, we must create a second project of type "Android App (Xamarin)" with Visual Studio. Actually, it's the "Doc-Inventory" application that you can find in the documentation and that you can find in the Android (Java) Yoctopuce library.

Now that we have"converted" our library into a library that can be used with Xamarin, we are going to see how to implement a very basic application which lists the detected Yoctopuce modules. The generated YoctoAPIBindings.dll file is located in the /bin/Debug/ or /bin/Release sub-directory. Go in the "Build" menu and select "Build solution", or use the Ctrl+Shift+B keyboard shortcut. There, the "Android Bindings library" is ready for compiling. Make sure to set the build action property to LibraryProjectZip The last step is to modify the "build action" property of the YoctoAPI.aar file and to select " LibraryProjectZip". You must add the YoctoAPI.aar file to the project
To add this YoctoAPI.aar file to the Visual Studio project, you must right-click on the Jars subdirectory and select "Add"->"Existing Item.". The YoctoAPI.aar file is located in the "Binaries" subdirectory.

To do so, we must download our Android library from our web site and unzip the archive on our disk. In our case, we only need to add the YoctoAPI.aar file, which is the precompiled version of our Android library. This project contains a Jars subdirectory in which we must add all the Android libraries written in Java that we will use later on. We must create an Android Bindings library project to convert our Java library into C# So, we start by creating an "Android Bindings library" that we call "YoctoAPIBindings".

dll file can then be used directly in your Xamarin Android application.
USING A DLL FILE IN AN ANDROID STUDIO PROJECT CODE
dll file containing C# code and the Java library. The solution to use these languages in a single application is to create an "Android Bindings library" which is going to create a C# "wrapper" for our library. Xamarin uses C# as programming language, but our library is written in Java.

In this post, we used Visual Studio Community 2019 under Windows 10, but the process is identical with all the versions of Visual Studio that support Xamarin.Ĭreating an "Android Bindings library" project We also recommend that you read our tutorial on how to use our modules on Android. If it is not the case, we recommend that you start by reading the first posts of the " For the beginners" series, most particularly that on the logical structure of Yoctopuce devices. We assume that you have at least some minimal knowledge of how our modules work. To test this tool, we are going to write a short application which is simply going to display the list of connected Yoctopuce modules which are detected when pushing a button. As most computer frameworks, Xamarin is supposed to help us save development time and to allow us to reuse the code on all the platforms. Since 2016, when Microsoft bought Xamarin, this tool is directly embedded into Visual Studio. Xamarin is a tool enabling you to write mobile applications in C#, among other things. This week, we are going to see how to create an Android application using our modules with Xamarin. Indeed, some of our customers use Xamarin and C# to implement their mobile applications. However, it's not the only available tool. In our previous posts, we always used Android Studio to implement our applications.
