Add the JNI so file to the Android Studio Gradle Project

Add the JNI so file to the Android Studio Gradle Project

First, create the entire jni directory under the app directory of the Android Studio (version 1.2.2) project. The jni directory contains Android. mk, Application. mk, various C/C ++ and Assembly source files. Then, use the ndk_build tool to compile the file. Then the tool automatically generates the libs Directory, which contains every so file of the processor architecture you specified in Application. mk.

If you reference a third-party so, directly store the relevant files in the libs directory.

Edit the build. gradle file in the app directory and add the following code to it:

 

 sourceSets {        main {            jniLibs.srcDirs = ['libs']        }    }

 

 

The complete build. gradle file is as follows:

 

 

apply plugin: 'com.android.application'android {    compileSdkVersion 22    buildToolsVersion 22.0.1    defaultConfig {        applicationId com.qianmi.myapp        minSdkVersion 15        targetSdkVersion 22        versionCode 1        versionName 1.0    }    buildTypes {        release {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }    }    lintOptions {        disable 'InvalidPackage'    }    sourceSets {        main {            jniLibs.srcDirs = ['libs']        }    }    packagingOptions {        exclude 'META-INF/services/javax.annotation.processing.Processor'    }}dependencies {    compile fileTree(dir: 'libs', include: ['*.jar'])    compile 'com.android.support:appcompat-v7:22.2.0'    compile 'com.google.code.gson:gson:2.3'    compile 'com.mcxiaoke.volley:library:1.0.16'    compile 'com.android.support:design:22.2.0'    compile 'com.android.support:cardview-v7:22.2.0'    compile 'com.android.support:recyclerview-v7:22.2.0'    compile 'com.github.bumptech.glide:glide:3.6.0'    compile 'com.jakewharton:butterknife:7.0.1'}
