Android Studio解决unspecified on project app resolves to an APK archive which is not supported

          出现该问题unspecified on project app resolves to an APK archive which is not supported as a compilation dependency的情形可能是：创建了两个Module，其中一个Module依赖另一个Module而导致了出现该问题；

          如果在Android Studio中，有ModuleA和ModuleB，我们希望ModuleA依赖ModuleB，运行时候可能会出现该问题，查看被依赖的ModuleB的build.gradle，里面可以看到：

apply plugin: 'com.android.application'

解决方法：将上面该句改为：

apply plugin: 'com.android.library'

如果说，我们ModuleB仍然需要生成apk，则我们需要将其中公共的代码放到一个Module，作为一个support的库；
