出现的问题： Manifest merger failed : Attribute application@allowBackup value=(false) from AndroidManifest.xml:116:9-36 is also present at [manager:common:unspecified:release] AndroidManifest.xml:12:9-35 value=(true).
Suggestion: add 'tools:replace="android:allowBackup"' to <application> element at AndroidManifest.xml:114:5-1136:19 to override.
解决方法：
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="包名">
在application节点添加
<application tools:replace="android:allowBackup" ......
同样的还有
tools:replace="android:icon, android:theme,android:allowBackup"
