The Android Native Development Kit (NDK) provides a cross-compiling tool for compiling code written in C/C++ can be compiled to ARM, or x86 native code (or their 64-bit variants) for Android.[4][5] The NDK uses the Clang compiler to compile C/C++. GCC was included until NDK r17, but removed in r18 in 2018.
Native libraries can be called from Java code running under the Android Runtime using System.loadLibrary, part of the standard Android Java classes.[6][7]
Command-line tools can be compiled with the NDK and installed using adb.[8]
Android uses Bionic as its C library, and the LLVM libc++ as its C++ Standard Library. The NDK also includes a variety of other APIs:[9] zlib compression, OpenGL ES or Vulkan graphics, OpenSL ES audio, and various Android-specific APIs for things like logging, access to cameras, or accelerating neural networks.
The NDK includes support for CMake and its own ndk-build (based on GNU Make). Android Studio supports running either of these from Gradle. Other third-party tools allow integrating the NDK into Eclipse[10] and Visual Studio.[11]
For CPU profiling, the NDK also includes simpleperf[12] which is similar to the Linux perf tool, but with better support for Android and specifically for mixed Java/C++ stacks.

Android Honeycomb is the codename for the third major version of Android, designed for devices with larger screen sizes, particularly tablets. It is the eighth version of Android. It is no longer supported, as of November 14, 2016. Android Honeycomb debuted with the Motorola Xoom in February 2011. Besides the addition of new features, Android Honeycomb introduced a new so-called "holographic" user interface theme and an interaction model that built on the main features of Android, such as multitasking, notifications, and widgets.
Android software development is the process by which applications are created for devices running the Android mobile operating system. Google states that "Android apps can be written using Kotlin, Java, and C++ languages" using the Android software development kit (SDK), while using other languages is also possible. All non-Java virtual machine (JVM) languages, such as Go, JavaScript, C, C++ or assembly, need the help of JVM language code, that may be supplied by tools, likely with restricted API support. Some programming languages and tools allow cross-platform app support (i.e. for both Android and iOS). Third party tools, development environments, and language support have also continued to evolve and expand since the initial SDK was released in 2008. The official Android app distribution mechanism to end users is Google Play; it also allows staged gradual app release, as well as distribution of pre-release app versions to testers.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
