  Consider using CMake or ndk-build integration. For more information, go to:

  Alternatively, you can use the experimental plugin:

   https://developer.android.com/r/tools/experimental-plugin.html

sourceSets { main { jni.srcDirs = [] } }

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

这样就可以运行了，是不是跟我再main下面建的文件夹就是jniLibs 有关啊
