You can edit, compile, and deploy your code multiple times to the same emulator. The emulator is a separate process that continues to run. Once your app has started, you can set breakpoints and use the debugger to step through code, examine locals, and watch values. Visual Studio starts the emulator, which takes a few seconds to load and deploy your code. Here's what the default app looks like in an Android emulator. Press F5 to start debugging, or Shift+ F5 to start without debugging. If you have installed other emulators or connected an Android device, you can choose them in the deployment target dropdown list. The Output window displays the output of the build process for the two projects in the solution.Ĭhoose one of the Android emulator profiles as your deployment target. On the menu bar, choose Build > Build Solution. If the Solution Platforms list isn't showing, choose Solution Platforms from the Add/Remove Buttons list, and then choose your platform. If it is not already selected, choose x86 from the Solution Platforms dropdown list. To build and run the default Native Activity app If you prefer to test your app on another target, you can load the target emulator or connect the device to your computer. For this initial test, run the app on one of the device profiles installed by the Android emulator. It's set as the startup project by default, so that it can be deployed and run directly from Visual Studio.īuild and run the default Android Native Activity appīuild and run the app generated by the template to verify your installation and setup. It also contains the build.xml file that controls the Ant build process. This contains the resources and AndroidManifest.xml file where you set manifest properties. apk file for deployment on an Android device or emulator. so file which is picked up by the Packaging project. This Native Activity app project is compiled into a shared library. The implementation of the entry points from the glue code are in main.cpp. MyAndroidApp.NativeActivity contains the references and glue code for your app to run as a Native Activity on Android. The new Android Native Activity app solution includes two projects: Visual Studio creates the new solution and opens Solution Explorer. In the Configure your new project dialog box, enter a name like MyAndroidApp in Project name, and then choose Create. In the Create a new project dialog box, select the Native-Activity Application (Android) template, and then choose Next. In Visual Studio, choose File > New > Project. In this tutorial, you'll first create a new Android Native Activity project and then build and run the default app in an Android emulator. Make sure that the required third-party tools and SDKs are included in the installation, and that an Android emulator is installed. For more information, see Install cross-platform mobile development with C++. Requirementsīefore you can create an Android Native Activity app, you must make sure you've met all system requirements, and installed the Mobile development with C++ workload in Visual Studio. L Android Native Development Kit ou Android NDK est une interface de programmation du système dexploitation Android permettant de développer directement dans le langage du matériel cible, par opposition au Android SDK qui est une abstraction en bytecode Java, indépendante du matériel. Additional topics walk through the developer lifecycle of editing, building, debugging and deploying Native Activity code. This topic will guide you through creation of a simple Native Activity app that uses OpenGL. Native Activity code is popular for creating gaming and graphic intensive apps that use Unreal Engine or OpenGL. The Android NDK introduced the ability to create Native Activity apps with Android API Level 9. Some Java JNI code acts as glue to allow your C/C++ code to interact with Android. The Android Native Development Kit (NDK) is a toolset that allows you to implement the majority of your Android app using pure C/C++ code. By the end of this book, you will be able to create an engaging, complete gaming application.When you install the cross-platform Mobile development with C++ workload, Visual Studio can be used to create fully functional Android Native Activity apps. Each chapter aims to take you one step closer to building your application. Through the course of this book, you will learn how to write portable multi-threaded native code, use HTTP networking in C++, play audio files, use OpenGL ES 3, and render high-quality text. The book takes you through many clear, step-by-step example applications to help you further explore the features of Android NDK and some popular C++ libraries and boost your productivity by debugging the development process. This is a hands-on guide to extending your game development skills with Android NDK. NDK is also the key for portability, which in turn allows a reasonably comfortable development and debugging process using familiar tools such as GCC and Clang toolchains. Master the skills you need to develop portable, highly-functional Android applications using NDKĪndroid NDK is used for multimedia applications that require direct access to system resources.
