android开发 项目运行时Error:warning: Ignoring InnerClasses attribute for an anonymous inner class

Android studio2.0运行项目时 build 成功 build目录下生成apk文件  但是不能自动直接安装运行 只能将apk文件拷出来安装 给调试带来很大麻烦。

编译时警告信息：

Error:warning: Ignoring InnerClasses attribute for an anonymous inner classError:(com.tencent.smtt.sdk.a.c) that doesn't come with anError:associated EnclosingMethod attribute. This class was probably produced by aError:compiler that did not target the modern .class file format. The recommendedError:solution is to recompile the class from source, using an up-to-date compilerError:and without specifying any "-target" type options. The consequence of ignoringError:this warning is that reflective operations on this class will incorrectlyError:indicate that it is *not* an inner class.

解决方法：项目根目录添加文件：proguard.cfg
