AndroidManifest.xml采用xml文件格式描述，使用xml标签的形式描述每个属性，AndroidManifest.xml的解析也遵循xml解析的规律，对AndroidManifest.xml的解析主要用到PackageManager,PackageInfo,ApplicationInfo三个类，PackageInfo描述了应用级的信息，包括应用的版本号，版本名称，对应AndroidManifest.xml最外层的信息，ApplicationInfo描述了标签之间的信息，包括声明的meta-data和activity信息。下面我做了一个小demo来测试下如何获得里面的值： 首先是要获得的Manifest的文件： [sourcecode language="java"] <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.packagemanagertest" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="15" android:targetSdkVersion="18" /> <compatible-screens > <screen android:screenSize="normal"/> <screen android:screenDensity="hdpi"/> </compatible-screens> <uses-permission android:name="android.permission.READ_SMS"/> <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.NFC"/> <application android:manageSpaceActivity="com.example.packagemanagertest.MainActivity" android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" android:name="TestApplication"> <activity android:name="com.example.packagemanagertest.MainActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest> [/sourcecode] 然后是主要的Activity：MainActivity [sourcecode language="java"] package com.example.packagemanagertest;
