<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="包名">

2、在application节点添加

 <application
        android:name="包名.app.MyApplication"
        android:allowBackup="false"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        tools:replace="android:allowBackup"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

3、如果有多个的话

<application
        tools:replace="android:icon,android:allowBackup">
