Android权限操作之uses-permission详解
本文实例讲述了android权限操作之uses-permission。分享给大家供大家参考,具体如下:
我们在安装android软件的时候,系统会提示该软件所需要的权限,相对于其他系统,android的权限非常多。我们在开发软件的时候,也需要声明相应的权限,比如希望软件能发短信,需要声明软件调用短信的权限,否则软件运行的时候就会报错。
android的权限在androidmanifest.xml文件里配置。androidmanifest文件中有四个标签与permission有关,它们分别是 <permission>、 <permission-group> 、<permission-tree> 和 <uses-permission>。其中最常用的是 <uses-permission>,当我们需要获取某个权限的时候就必须在我们的manifest文件中声明<uses-permission>。
<?xml version="1.0" encoding="utf-8"?> <manifest> <application> </application> <uses-permission /> <permission /> <permission-tree /> <permission-group /> ... </manifest>
<permission>和 <uses-permission>的作用相似,两者之间的不同之处,<uses-permission>是android预定义的权限,<permission>是自己定义的权限。 <permission>用的相对较少,<permission-group> <permission-tree>这两个标签就更少见了,简单说<permission-group> 就是声明一个标签,该标签代表了一组permissions,而<permission-tree>是为一组permissions声明了一个namespace。后面三个标签具体使用方法后续文章会有介绍。
<permission>定义方法如下:
<permission android:description="string resource" android:icon="drawable resource" android:label="string resource" android:name="string" android:permissiongroup="string" android:protectionlevel=["normal" | "dangerous" | "signature" | "signatureorsystem"] />
上面代码来自官方文档:http://developer.android.com/guide/topics/manifest/permission-element.html。propectionlevel这个属性是必须声明,告诉系统通知用户的应用要求许可,或允许谁认为获得许可的情况下。permissiongroup这个是可选的,与<permission-group>配合使用。label, name和icon用于描述权限。 <permission>的用法后面也会再详细分析。
<uses-permission>是我们用的最多的,官方文档定义方式如下:
<uses-permission android:name="string" />
例如,短信和电话权限的定义:
<uses-permission android:name="android.permission.call_phone" /> <uses-permission android:name="android.permission.send_sms"/>
下面是收集到的 <uses-permission>的资料,方便用的时候查找:
