Android Studio for NDK development

1. Create a new JNI directory in the src/main/directory first

2, here to steal a lazy, directly from other projects to copy Android.mk,application.mk,demo.cpp to the JNI directory

in the application.mk file, configure the following:

App_abi: = Armeabi armeabi-v7a arm64-v8a x86 x86_64 MIPS MIPS64
App_platform: = android-7

3, in the local.properties file configuration: ndk.dir=d\:\\android\\androidstudio\\ndk\\android-ndk-r10e

4, in the Build.gradle file in the Android node Defaultconfig The following configurations are configured in the node:

Android {    compilesdkversion    buildtoolsversion "22.0.1"    defaultconfig {        ApplicationID " Com.ycy.ndkdemo "        minsdkversion        targetsdkversion        1        versionname" 1.0 "        NDK {            ModuleName "demo"            ldlibs "log", "Z", "M"            abifilters "Armeabi", "armeabi-v7a", "arm64-v8a", "x86", "x86 _64 "," MIPS "," Mips64 "}}    }

5, through the above configuration basic OK, and then can be called in Java.

PS: This method calls native through C + + source code, and the resulting. So file is generated after the final compilation in App\build\intermediates\ndk\debug\lib

=================================================================================================

The second way to call C + + is described next

1, this method is on the basis of so library, directly on each CPU platform on the so library files in the src/main/jnilibs directory (new jnilibs directory)

2. Configure in the Android node in the Build.gradle file:

    Sourcesets {        main {java.srcdirs = [' Src/main/java ', ' Src/main/jnilibs '}    }

through the above configuration basic OK, and then you can call it heartily.

Finally, the two methods can only choose one, can not be used together, otherwise it will conflict.
