![]() This means that it needs to be compiled differently based on the architecture of the target device. Unlike Kotlin or the Java programming language, both of which execute on the Android Runtime (ART), any C++ in your Android app compiles directly into machine instructions. The significance of this may require a bit of context, especially if you build apps exclusively with Kotlin or the Java programming language. The new Android 11 (Google APIs) x86 system image supports ARM ABIs, while the older Android Oreo system image does not Details This allows the execution of ARM binaries for testing without the performance overhead of full ARM emulation. The new Android 11 system images are capable of translating ARM instructions to x86 without impacting the entire system. Previously, developers who were dependent on ARM libraries and could not build an x86 variant of their app either had to use system images with full ARM emulation, which are much slower than x86 system images when run on x86-based computers, or resort to physical devices. Native x86 support will help your apps have better performance and faster load times.įor additional support, a special Unity x86 developer page is available here.As part of the Android 11 developer preview we’ve released Android 11 system images, which are capable of executing ARM binaries with significantly improved performance. You can make sure that full debug information is NOT included by verifying that “Development Build” is not selected in the build settings section.Īs you just saw, it’s easy to create Android-based games for the x86 platform using the latest version of Unity 4 or Unity 5. Please note that the fat APK size will have a very small size increase unless full debug information is included. The resultant APK contains both x86 and ARM libraries, where upon download the device will select which library is applicable for its hardware type. With the use of the both the newest Unity gaming engine and Android SDK/NDK, developers have support for both X86 and ARM concurrently in a fat APK. That’s it! Your APK now has native x86 support. “Build Settings”: Ensure “Android” is selected, then click “Build”. “Build Settings” within the file drop-down menu. Within “Build Settings”, ensure “Android” is selected, then click “Build” (Figure 2).Īfter clicking “Build”, specify the save location.įigure 1. With your project open, click File > Build Settings to open “Build Settings” (Figure 1). Android SDK and NDK must also be updated to ensure full compatibility. When you create an Android build using Unity 4 or Unity 5, it automatically creates a fat APK containing both x86 and ARM libraries.īest practice: Follow Unity programming practices to ensure projects are kept up to date and your Unity software version is the latest. In addition to ARM, Unity now provides developers with native x86 support. If you’d like early access or version 4.5.4, please contact your Intel account manager. We’ll post an update here when the release goes live. Intel and Unity are working together to bring x86 Android functionality to an upcoming public release of Unity 4.6 and Unity 5. This article walks through the steps to produce a fat APK that includes both x86 and ARM libraries from within the latest Unity 4 or Unity 5 versions. Nordic Game 2015 partner Intel has some advice for developers looking to add x86 support to Android apps using the Unity game engine:Įnabling existing Unity ARM-based Android SDK games with native x86 support is straightforward and easy.
