Android Studio NDK Development configuration

One: Use Gradle experimental plugin

First of all, we can not use the Android studio default Gradle plugin, we need to change the Android Studio plugin Gradle Experimental plugin, this plugin is developed by Google, the URL here:

Http://tools.android.com/tech-docs/new-build-system/gradle-experimental

Gradle Experimental plugin is a new compiled plugin for Android studio that improves the compiler performance of the program. In addition, it supports the NDK, which compiles JNI applications. Currently (May 2016) The latest version is 0.7.0

II: Software Preparation:

• Gradle 2.10
• Android NDK r10e
• Android SDK Build Tools version 23.0.3

Three: Changes in the directory structure

The following red is required to modify the configuration, there are three main:

├──app/

│├──app.iml

│├── build.gradle----------> Module compilation configuration File

│└──src/

├── build.gradle ----------> Engineering Compilation configuration file

├──gradle/

│└──wrapper/

│├──gradle-wrapper.jar

│└── gradle-wrapper.properties ----------> Gradle version configuration file

├──gradle.properties

├──gradlew*

├──gradlew.bat

├──local.properties

├──myapplication.iml
