ObjectiveUsing the latest NDK, directly discard Cygwin, previously done Android projects to use the NDK will have to download the installation of Cygwin (simulated Linux environment), download the CDT (Eclipse C + + development plug-in), download the

Ndk-stack location error (dynamically loaded so), ndk-stackso We usually use ndk-stack to locate the so error in libs. When the so error is dynamically loaded on the SD card, it cannot be loaded multiple times. Otherwise, the location error may occur. Operation Command (Adb path) adb logcat | (ndk-stack path)

subsequent releases. As seen from this version of the NDK, these APIs support a very limited number of features, including: C standard library (LIBC), Standard math Library (LIBM), compression library (LIBZ), log Library (Liblog). ”Before you dive in, think of the NDK as a tool that enables Java to use the so package compiled by C + +. and bring this package together into the APK package.Get started here:F

For self-developed ndk, it should be a little excited to compile and run Hello-JNI. (Ubuntu environment) The establishment of the ndk development environment is easy to stop, but there are still several days of prompts: 1. In the C/C ++ environment of Eclipse, it is best to manually install the CDT plug-in, (See my other note. Eclipse CDT security guide.) Help --> install new sofeware is too difficult t

Android applications are developed in Java. Android ndk enables us to use the native code developed by C/C ++ on Android. There are two reasons to use ndk: one is to rationally reuse existing code, and the other is to improve the execution efficiency in some key parts of the program. For Android ndk development, in addition to the general Android development envi

API header file declaration Google explicitly declares that the API is stable and supports the current published API in all subsequent releases. As you can see from this version of NDK, these APIs support a very limited number of functions, including the C standard library (LIBC), the standard math Library (LIBM), the compression library (LIBZ), and the log library (Liblog).

transplantation. If you have a large amount of C-language code in your existing applications, using ndk not only accelerates the development process of your project, but also keeps modifications synchronized between your android and non-android projects. This is especially true for OpenGL ES applications written for other platforms. Don't think that as long as native code is used, application efficiency can be improved. Conversion between Java and na

Interface (Java Local call). Starting with Java1.1, JNI became part of the Java platform, allowing Java code to interact with code written in other languages, such as cc++. The concept of JNI was not introduced from the Android release. Simply put, Android's NDK provides some cross-compilation tool chains and Android libraries, which can be invoked by developers when writing native language programs. The NDK
