android 合并清单文件失败的解决

Manifest merger failed : Attribute application@allowBackup value=(true) from AndroidManifest.xml:18:9-35

is also present at :imsdk-plus-5.4.666: AndroidManifest.xml:16:9-36 value=(false).

Suggestion: add 'tools:replace="android:allowBackup"' to <application> element at AndroidManifest.xml:15:5-30:19 to override.

解决方法

清单文件application中新增下面两个属性

android:allowBackup="true"
tools:replace="allowBackup"
