Whether you’re targeting Universal Windows Platform (UWP), Android, or iOS, Visual Studio enables building cross-platform C++ mobile applications with full editing and debugging capabilities all in one single IDE.In this blog post, we will focus on how to build Android and iOS apps with C++ in Visual Studio. Why? Those who are building computationally intensive apps such as games and physics simulations choose C++ for its unparalleled performance, and the others choose C++ for its cross-platform nature and the ability to leverage existing C/C++ libraries in their mobile applications. Google APIs Intel x86 Atom System Image Google APIs Intel x86 Atom_64 System Image When it comes to building mobile applications, many developers write most or a part of the apps in C++. VS Code has built-in debugging support for the Node.js runtime and can debug JavaScript, TypeScript, or any other language that gets transpiled to JavaScript. For debugging other languages and runtimes RetroArch is the one-for-all emulator everyone needs, but having seen the.Install Visual Studio for Android and iOS developmentFirst, download Visual Studio 2017 and launch the Visual Studio installer.To build Android or iOS applications, choose the “ Mobile development with C++” workload under the “ Mobile & Gaming” category.Android development: By default, this workload includes the core Visual Studio editor, the C++ debugger, GCC and Clang compilers, Android SDKs and NDKs, Android build tools, Java SDK, and C++ Android development tools. Finally, we will talk about how the C++ mobile solution can be used in conjunction with Xamarin. Next we will use the Visual Studio IDE to write C++ and Java code, then we will use the world-class Visual Studio debugger to catch issues in C++ and Java code.The app should build and run successfully, and you should see the app changing colors in the background. Once the project is created, in the Solution Platforms dropdown, choose the right architecture that matches the Android emulator or device that you’re using, and then press F5 to run the app.By default, Visual Studio uses the Clang toolchain to compile for Android. If you’d rather start with a cross-platform solution to target multiple mobile platforms, jump to the next section Build an OpenGLES Application on Android and iOS where we’ll talk about building an app that targets both platforms with shared C++ code.You can find the Android templates under Visual C++ -> Cross Platform -> Android node.Here we’re going to create a new Native Activity Application (Android), which is popular for creating games and graphical-intensive apps. Create a new Android application using project templatesIf you plan to start with targeting Android first and worry about other platforms later, the VS built-in Android project templates including Native-Activity Application, Static Library, Dynamic Shared Library, could be a great starting point. This should give you everything you need to start building Android applications.IOS development: if you’re also targeting iOS, check “ C++ iOS development tools” in the Optional Component list and you would be good to go.
![]() Visual Studio Emulator How To Build Android![]() Build and run the app on iOSThe iOS project created in the solution can be edited in Visual Studio, but because of licensing restrictions, it must be built and deployed from a Mac. The OpenGL ES app should build and run successfully and you will see a colored 3D spinning cube. Just like run the Android Native Activity app we discussed earlier, in the Solution Platforms dropdown, select the right architecture that matches the Android emulator or device that you’re using, and then press F5 to run the app. ![]() The following screenshot shows a single solution with 4 projects, one for each mobile platform and one shared project for common C++ code.To learn more, please refer to how Half Brick makers of popular mobile games Fruit Ninja and Jetpack Joyride use Visual Studio for a C++ cross-platform mobile development experience. With Visual Studio, you can easily share and re-use your existing C++ libraries through the shared project component to target multiple platforms. Visual Studio to target all mobile platformsIf you’re building an app to target multiple mobile platforms (Android, iOS, UWP) and wish to share the common code in C++, you can achieve this by having one single Visual Studio solution and leverage the same code-authoring and debugging experience all in the same IDE. You should see the same colored 3D spinning cube in the iOS Simulator.This article Build an OpenGL ES Application on Android and iOS includes more details about the OpenGLES project. Typing in “->” following an object instance in the C++ code will display a list of members, and you can insert the selected member into your code by pressing TAB, or by typing a space or a period. Member list shows you a list of valid members from a type or namespace. These editing capabilities not only light up in the common code, but are context-aware of the target platform when you write platform-specific code.Member list and Quick Info, as shown in the following screenshot, are just two examples of the IntelliSense features Visual Studio offers. Record a video for youtube on macIn the example in the screenshot, Visual Studio brings in the definition of _android_log_print method that is defined in the Android SDK log.h file as an embedded window into the current cpp file, making reading and writing Android code more efficiently.Debug C++ code with the world-class Visual Studio debuggerTroubleshooting issues in the code can be time-consuming. You can find Peek Definition by opening the context menu on right click or shortcut Alt+F12 for a method that you want to explore. Visual Studio offers many great code navigation features, including Go To Definition, Go To Line/Symbols/Members/Types, Find All References, View Call Hierarchy, Object Browser, and many more, to boost your productivity.The Peek Definition feature, as shown in the following screenshot, brings the definition to the current code file, allows viewing and editing code without switching away from the code that you’re writing. In the following screenshot, Visual Studio is showing a list of the available Android-specific functions when the Android Native Activity project is active.Auto-complete, squiggles, reference highlighting, syntax colorization, code snippets are some of the other useful productivity features to be of great assistance in code writing and editing.Navigating in large codebases and jumping between multiple code files can be a tiring task. IntelliSense is implemented based on the Clang toolchain when targeting the Android platform. Java debugging and language support for AndroidWhether you’re writing Java or C++ code in your Android apps, Visual Studio has it covered. In the example in the screenshot below, the Autos window is showing value changed in the Android sensorManager and accelerometerSensor types.The Android debugging experience in Visual Studio also supports for debugging pre-built Android application via other IDE(s), other basic debugger capabilities (tracepoints, conditional breakpoints) and advanced features such as debugger visualizations (Natvis Support) and attaching to a running Android application as well.You can find more information about the C++ debugger in this blog post C++ Debugging and Diagnostics. When the breakpoint is hit, you can watch the value of variables and complex expressions in the Autos and Watch windows as well as in the data tips on mouse hover, view the call stack in the Call Stack window, and step in and step out of the functions easily. Set breakpoints in your Android C++ code and press F5 to launch the debugger.
