XML内容如下：

<?xmlversion="1.0"encoding="utf-8"standalone="no"?><manifestxmlns:android="http://schemas.android.com/apk/res/android"package="com.dongbao.wauoen.interappactivitytesting"platformBuildVersionCode="23"platformBuildVersionName="6.0-2704002"><uses-permissionandroid:name="android.permission.READ_EXTERNAL_STORAGE"/><applicationandroid:allowBackup="true"android:icon="@mipmap/ic_launcher"android:label="@string/app_name"android:supportsRtl="true"android:theme="@style/AppTheme"><activityandroid:exported="true"android:name="com.dongbao.wauoen.interappactivitytesting.MainActivity"><intent-filter><actionandroid:name="android.intent.action.MAIN"/><categoryandroid:name="android.intent.category.LAUNCHER"/></intent-filter></activity><activityandroid:enabled="@bool/use_activity"android:exported="true"android:icon="@drawable/ic_chooser"android:label="@string/choose_file"android:name="com.ipaulpro.afilechooser.FileChooserActivity"/><activityandroid:exported="true"android:name="com.dongbao.wauoen.interappactivitytesting.ExampleActivity"android:permission="android.permission.READ_EXTERNAL_STORAGE"/></application></manifest>

2.解析过程：主要获取开放activity的信息，并保存到xml文件中
