repositories {
    
    
    //flatDir {
    
    
    //    dirs 'libs'
    //}
    maven {
    
     url 'https://plugins.gradle.org/m2/' }
    maven {
    
     url 'https://maven.aliyun.com/nexus/content/repositories/google' }
    maven {
    
    
        url 'https://maven.aliyun.com/nexus/content/groups/public'
    }
    maven {
    
    
        url 'https://maven.aliyun.com/nexus/content/repositories/jcenter'
    }
    maven {
    
     url 'https://bintray.com' }
    maven {
    
     url 'https://jcenter.bintray.com' }
}

2.build.gradle 文件增加 jniLibs.srcDirs = [‘libs’]

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