android studio引入so库

今天在使用百度语音时引入百度提供的so库，运行后一直提示找不到native method，搞了很久才发现是由于Android studio目前为止还无法做到自动导入so库，我们需要手动将libs中的.so文件导入，使用一下代码：

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

原文代码为

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.3"

    defaultConfig {
        applicationId "com.bearya.baiduvoice"
        minSdkVersion 16
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }
    sourceSets {
        main {
            jniLibs.srcDirs = ['libs']
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:24.2.1'
    testCompile 'junit:junit:4.12'
    compile files('libs/com.baidu.tts_2.2.9.20161020_154fa02_release.jar')
    compile files('libs/galaxy-v2.0.jar')
}
