介绍一下android的各种权限。

代码如下：

<
manifestxmlns:android
manifestxmlns:android
=
"http://schemas.android.com/apk/res/android"
      package
=
"net.sunniwell.launcher"
      android
android:versionCode
="1"android
:versionName
=
"1.0.1"
>

关于自定义权限，这是很好的例子，其他apk程序要想使用Launcher的功能必须添加这些权限，而这些权限都是在这里声明的。

这个是安装快捷方式的权限定义：

<
permission
        android:name
=
"com.android.launcher.permission.INSTALL_SHORTCUT"
        android:permissionGroup
=
"android.permission-group.SYSTEM_TOOLS"
        android:protectionLevel
=
"normal"
        android:label
=
"@string/permlab_install_shortcut"
        android:description
=
"@string/permdesc_install_shortcut"
/>

这个是卸载快捷方式的权限定义：

<
permission
        android:name
=
"com.android.launcher.permission.UNINSTALL_SHORTCUT"
        android:permissionGroup
=
"android.permission-group.SYSTEM_TOOLS"
        android:protectionLevel
=
"normal"
        android:label
=
"@string/permlab_uninstall_shortcut"
        android:description
=
"@string/permdesc_uninstall_shortcut"
/>

这个是读取launcher.db内容的权限定义：

<
permission
        android:name
=
"net.sunniwell.launcher.permission.READ_SETTINGS"
        android:permissionGroup
=
"android.permission-group.SYSTEM_TOOLS"
        android:protectionLevel
=
"normal"
        android:label
=
"@string/permlab_read_settings"
        android:description
=
"@string/permdesc_read_settings"
/>

这个是修改和删除launcher.db内容的权限定义：

<
permission
        android:name
=
"net.sunniwell.launcher.permission.WRITE_SETTINGS"
        android:permissionGroup
=
"android.permission-group.SYSTEM_TOOLS"
        android:protectionLevel
=
"normal"
        android:label
=
"@string/permlab_write_settings"
        android:description
=
"@string/permdesc_write_settings"
/>

这些是Launcher的权限声明，通过这些就能看出launcher的大概功能了：

<
uses-permissionandroid:name
uses-permissionandroid:name
=
"android.permission.CALL_PHONE"

uses-permissionandroid:name
uses-permissionandroid:name

uses-permissionandroid:name
uses-permissionandroid:name
=
"net.sunniwell.launcher.permission.WRITE_SETTINGS"

            android:name
=
"Launcher"
           是否
android:launchMode
=
"singleTask"
            android:clearTaskOnLaunch
=
"true"
            这个activity是否在被杀死或者重启后能恢复原来的状态：
android:stateNotNeeded
=
"true"
            android:theme
=
"@style/Theme"
            android:screenOrientation
=
"landscape"
            android:windowSoftInputMode
=
"stateUnspecified|adjustPan"
>

<
intent-filter
>

<
meta-data
            android:name

"android.app.default_searchable"
            android:value
=
"*"
/>

安装快捷方式的广播接收器：

 

<!-- Intent received used to install shortcuts from other applications-->


<

            android:name

".InstallShortcutReceiver"
            android:permission
=
"com.android.launcher.permission.INSTALL_SHORTCUT"

<

>

<
actionandroid:name
actionandroid:name
=
"com.android.launcher.action.INSTALL_SHORTCUT"
/>

</
intent-filter
>

</
receiver
>


<!-- Intent received used to uninstall shortcuts from other applications-->

卸载快捷方式的广播接收器：

 

<
receiver
            android:name
=
".UninstallShortcutReceiver"
            android:permission
=
"com.android.launcher.permission.UNINSTALL_SHORTCUT"

<
intent-filter
>

<
actionandroid:name
actionandroid:name
=
"com.android.launcher.action.UNINSTALL_SHORTCUT"
/>

</
intent-filter
>

</

>

声明ContentProvider，用于对launcher.db操作：

<!-- The settings provider contains Home's data, like the workspacefavorites -->

<
provider
            android:name
=
"SWLauncherProvider"
            android:authorities
=
"net.sunniwell.launcher.settings"
            android:writePermission
=
"net.sunniwell.launcher.permission.WRITE_SETTINGS"
            android:readPermission
=
"net.sunniwell.launcher.permission.READ_SETTINGS"
/>


</
application
>

<
uses-sdkandroid:minSdkVersion
uses-sdkandroid:minSdkVersion
=
"4"
/>

</
manifest
>

说明：
1.
<manifest标签头部还应声明：
android:sharedUserId="android.uid.shared"，作用是获得系统权限，但是这样的程序属性只能在build整个系统时放进去（就是系统软件）才起作用，手动安装是没有权限的。
