It provides headers and 78 libraries that allow you to build activities, handle user input, use hardware sensors, 79 access application resources, and more, when programming in C or C++. If you write 80 native code, your applications are still packaged into an .apk file and they still run 81 inside of a virtual machine on the device. The fundamental Android application model 82 does not change.</p> 83 84 <p>Using native code does not result in an automatic performance increase, 85 but always increases application complexity. If you have not run into any limitations 86 using the Android framework APIs, you probably do not need the NDK.
