这个错误是我在使用了2个module之后出现的。

由于Gradle插件默认会启用Manifest Merger Tool，若Library项目中manifest也定义了与主项目相同的属性（例如默认生成的android:icon和android:theme），则此时会合并失败，并报上面的错误。

 

解决方法

 

    在Manifest.xml的application标签下添加tools:replace="android:icon, android:theme"（多个属性用,隔开，并且记住在manifest根标签上加入xmlns:tools="http://schemas.android.com/tools"，否则会找不到namespace哦）而对于我这次的错误是只需要添加tools:replace="android:lable"就可以啦!

事实上logcat 已经教我如何纠正错误啦（上方红色段落）所以碰到错误就直接分析logcat 吧，不能慌哦
