接入阿里百川的用户反馈，AndroidManifest allowBackup属性冲突

[spuermax]

接入阿里百川用户反馈之后，项目运行报错。

Attribute application@allowBackup value=(false) from AndroidManifest.xml:48:9-36 is also present at [com.github.lovetuzitong:MultiImageSelector:1.2] AndroidManifest.xml:14:18-44 value=(true). Suggestion: add 'tools:replace="android:allowBackup"' to <application> element at AndroidManifest.xml:37:5-374:19 to override.
