}

　　

main目录里面AndroidMainfest.xml内容，引用了gradle配置的一些字段

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.win10_jycainiao.test">

    <application
        android:name="${MY_NAME}"
        android:icon="${MY_ICON}"
        android:label="${MY_LABEL}"
        android:supportsRtl="true"
        android:theme="@style/Theme.AppCompat.Light.NoActionBar">
        <activity android:name="${MY_MAIN}" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

　　

main_用来做main的完全维度包

马甲包如果有新加或者更改 application、activity，要对gradle中的字段进行赋值，并且在AndroidMainfest.xml中添加activity
