unspecified on project XXX resolves to an APK archive which is not supported as a compilation depend

在Android Studio中可以依赖某一个module

有时，会出现下面问题：

<pre name="code" class="html">Warning:Dependency XXX:XXX:unspecified on project XXX resolves to an APK archive which is not supported as a compilation dependency. File: XXX/outputs/apk/XXX.apk

解决：

1、找到对应的要依赖module

2、修改module下的buile.gradle

apply plugin: 'com.android.application'

修改为

apply plugin: 'com.android.library'

3、去掉applicationId
