android自定义权限的实现

来源：互联网发布：crm数据分析报告编辑：程序博客网时间：2024/05/16 12:52

在android开发中，有时需要利用自定义权限来保证android应用的安全，今天写一个自定义权限的小案例。包含了访问activity，service，以及发送广播可广播接受者，和自定义权限。

首先，新建两个工程，一个叫做security，另一个叫做securitytest

在seurity中定义，声明，并利用自定义的几个权限，在securitytest中就像用普通的权限一样，利用即可

security中声明权限如下：

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.security"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="11"        android:targetSdkVersion="18" />    <permission android:name="com.tct.permission.READ_PROVIDER"  android:protectionLevel="dangerous">    </permission>    <permission android:name="com.tct.apermission.WRITE_PROVIDER" android:protectionLevel="dangerous">    </permission>    <permission        android:name="com.tct.attach.start_activity"        android:protectionLevel="normal" >    </permission>    <permission        android:name="com.tct.attach.service.permission"        android:protectionLevel="normal" >    </permission>    <permission        android:name="com.tct.attach.broadcastreceiver"        android:protectionLevel="dangerous" >    </permission>    <uses-permission android:name="com.tct.attach.service.permission" />    <uses-permission android:name="com.tct.attach.start_activity" />    <uses-permission android:name="com.tct.attach.broadcastreceiver" />    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity            android:name="com.example.security.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>        <service            android:name="com.example.security.MyService"            android:permission="com.tct.attach.service.permission" >            <intent-filter>                <action android:name="com.test.action.service" >                </action>                <category android:name="android.intent.category.DEFAULT" >                </category>            </intent-filter>        </service>        <activity            android:name="com.example.security.MyActivity"            android:permission="com.tct.attach.start_activity" >            <intent-filter>                <action android:name="android.intent.action.MAIN" >                </action>                <category android:name="android.intent.category.DEFAULT" >                </category>            </intent-filter>        </activity>        <receiver            android:name="com.example.security.MyBroadcaseReceiver"            android:permission="com.tct.attach.broadcastreceiver" >            <intent-filter>                <action android:name="com.tct.receiver.action" >                </action>            </intent-filter>        </receiver>        <activity android:name="com.example.security.ShowReceiverActivity" >        </activity>        <activity android:name="com.example.security.MyBroadCast" >        </activity>        <provider            android:name="com.example.contentprovider.MyContentProvider"            android:authorities="com.liuhang.urlcontent"            android:exported="true" ><!--             android:path="content://com.liuhang.urlcontent/person/3" -->            <path-permission                android:pathPrefix="/person"                android:readPermission="com.tct.apermission.WRITE_PROVIDER"                android:writePermission="com.tct.apermission.WRITE_PROVIDER"                ></path-permission>                        <grant-uri-permission android:pathPrefix="/person"/>        </provider>    </application></manifest>

securitytest中的AndroidManifest.xml文件如下：

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.securitytest"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="12"        android:targetSdkVersion="18" />        <uses-permission android:name="com.tct.attach.service.permission"/>    <uses-permission android:name="com.tct.attach.start_activity"/>    <uses-permission android:name="com.tct.attach.broadcastreceiver"/>    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>    <uses-permission android:name="com.tct.permission.READ_PROVIDER"/>    <uses-permission android:name="com.tct.apermission.WRITE_PROVIDER"/>    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity            android:name="com.example.securitytest.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>                <receiver android:name="com.example.securitytest.MyTestReceiver">            <intent-filter>                <action android:name="com.test.permission.sendbroadcast"></action>            </intent-filter>        </receiver>    </application></manifest>

只有当在securitytest中利用了这些权限才可以访问对应的activity，service，contentprovider以及接受和发送对应的广播。
