, and has a own Dalvik virtual machine instance, compared to the Java Virtual Machine (JVM), Dalvik is specifically for mobile devices, it on the phone memory, CPU performance is limited and so on the situation has been optimized processing. Application Framework layer (application framework) This layer primarily provides some of the core applications that may be used to build applications using these APIs, and developers can build their own applications by using these APIs.

The Android NDK is preceded by the "native" word in the SDK, native Development Kit, which Google calls "NDK". As we all know, the Android program runs in the Dalvik virtual machine, NDK allows users to perform part of the program using native code languages such as C + +. The NDK includes: The tools and build files needed to generate a native code base from C + +. Embed a consistent native library in a

Android's NDK development I. Background of the creation of NDK Since its inception, the Android platform has supported C and C + + development. As we all know, the Android SDK is based on Java implementation, which means that third-party applications that are developed based on the Android SDK must use the Java language. But this is not equivalent to "Third-par
