android是否授予应用程序安装顺序的权限？

AppA在清单中定义权限，如

package="com.example.definepermission"
android:versionCode="1"
android:versionName="1.0" >    
<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="21" />

 <permission 
     android:name="com.example.permission.test.permissionA"
     android:protectionLevel="normal"
     >         
 </permission>


<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" 
        android:permission="com.example.permission.test.permissionA">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

如果首先安装AppA，android setting.mPermission将包含com.example.permission.test.permissionA，然后安装AppB，android将向AppB授予此正常权限

这种情况可以在谷歌nexus，HW mate8，维梧复制。 谷歌地图的新版本首先安装在中国的andorid手机上（中国唯一的seal），而在所有的谷歌gms（谷歌播放服务）leat中，这也将复制这种情况

android是否授予应用程序安装顺序的权限

对。引用几年前的话：

Android中的自定义权限是“wins中的第一个”。换句话说，对于给定的

android:name

，无论哪个应用程序首先具有

元素，都可以为所有后续应用程序定义该权限的详细信息

这可以解决这个问题，但我想知道为什么

**//如果这是一个现有的非系统包，则 //我们无法向其添加任何新权限
