浅谈manifest.xlm配置文件application中属性
今天在app中引入新的依赖库时出现一个令人费解的问题，大概意思是说我引入的依赖库中android:icon="@mipmap/ic_launcher" android:label="@string/app_name"依赖库中也有同样的属性，之前对这些属性没有研究过，不是很了解，如今遇见此类问题已经解决，和小伙伴们分享一下！
1、问题重现
如果你的应用中有多个依赖库，并且依赖不全是在gradle里面配置，也就是说有的依赖库使用jar包引入的，那么这时候合并manifest的时候很有可能报错：
情况1：jar包的依赖库中android:icon="" android:label=""这两个属性和应用中的属性引用不同（例如：jar包中android:icon="@mipmap/ic_launcher" ，应用中android:icon="@drawable/ic_launcher" ）,这时候你就会用到tools:replace=""属性，如果两个或两个以上的属性引用不同就会报错
情况2：大家可能都知道Android API Level 8及其以上Android系统提供了为应用程序数据的备份和恢复功能即allowBackup属性，默认只是true，当你的应用设置了此属性false，而依赖库中没有设置此属性也就是true此时合并manifest的时候会冲突，必须使用tools:replace=""属性替换，同样有两个或以上的设置不同就会报错
下面是一种情况的报错信息：

解决的方法很明显，修改jar包中属性的应用和app中的一致，如果还有问题，根据相应的报错信息将gradle中对应的配置手动进行依赖，然后修改属性引用，新手刚刚开始写博客，希望大家多多支持，谢谢大家！
