需要在gradle中配置下面的代码，原因是引用了多个libraries文件
defaultConfig {
multiDexEnabled true
}
2.Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: android/support/v4/app/BackStackState$1.class

> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/android/volley/ServerError.class
原因：在所添加的jar包或aar包中也引用了support-V4,与工程中引用的相冲突
Ctrl N --> 在搜索框中输入BackStackState --> 查找到所有引用该类的类，这些类即为引起冲突的类
去掉本工程中gradle中用于引用有冲突的包的代码或者将冲突的代码从jar包或aar包中移除，确保一个module中只引用了一份相同的第三方包
3.project sturcture和Project Structure 无论是按快捷键或者是从files中打开都不显示
event log中报：IllegalArgumentException:Multiple entries with same key: Google Inc.:Google APIs:23=Google APIs (Google Inc.) (API 23) and Google Inc.:Google APIs:23=Google APIs (Google Inc.) (API 23)
解决办法：先看一下系统配置的SDK的位置和Android Studio所用的路径是否一致，如果不一致重新配置系统的SDK路径或者是重新修改Android Studio的SDK路径
通过SDK Manager删除掉google API23
如果解决不了，卸载android studio -->重新安装 ,还有问题点击File --> Invalidate Cashes/Restart --> Invalidate and Restart,解决不了继续通过SDK Manager删除掉google API23

注: E:\as_workspaces\DJIgo\tongyan-djigo-lib\src\main\java\com\tongyan\lib\djigo\ui\view\ControlMoveView.java使用或覆盖了已过时的 API。
注: 有关详细信息, 请使用 -Xlint:deprecation 重新编译。 android studio-File->Project Structure->Android sdk location(路径应该不正确)

需要把dependencies中的lib包下面的jar包全部取消下，再添加。
