在我做的所有的应用程序的所有权限的转储上的Nexus 7，我得到（预期）的权限与保护等级0（NORMAL），1（危险），2（签字）。没有什么是3岁以下（SIGNATURE_OR_SYSTEM）日志*。

但也有很多的权限，其保护级别设置为18，有些是50。

我找不到这些值的重新present任何文件。有谁知道？

*它不记录下3.什么

Android系统新权限模型剖析与预警

解决方案

刚看到一个古老的悬而未决的问题。虽然你可能已经得到你的答案，我反正回答。它可以帮助别人。 ：）

  

也有很多，其保护级别设置为18和权限的一些是50。

下面code都PermissionInfo.java检索的Andr​​oid源：

  / **
 *附加​​标志{@link #protectionLevel}，相应的
 *要在＆lt; code＆GT;系统＆LT; / code取代;价值
 * {@link android.R.attr＃的ProtectionLevel}。
 * /
公共静态最终诠释PROTECTION_FLAG_SYSTEM = 0×10;

/ **
 *附加​​标志{@link #protectionLevel}，相应的
 *要在＆lt; code＆GT;发展＆LT; / code取代;价值
 * {@link android.R.attr＃的ProtectionLevel}。
 * /
公共静态最终诠释PROTECTION_FLAG_DEVELOPMENT = 0x20的;

所以，如果有一个签名/系统的权限，水平将18（0×10 | 0X2）。如果用于特殊的开发工具的许可使用，这将是50（为0x10 |为0x20 | 0X2）。

  

我找不到这些值的重新present任何文件。有谁知道？

正如我在现有的问题的回答，您可以检查的保护水平和这些权限在说明框架/基/核心/ RES / AndroidManifest.xml中和框架/基/数据的/ etc / platform.xml 。我张贴一些人在这里，供大家参考。

 ＆LT;！ - 配置用于调试的应用程序。 - ＆GT;
＆LT;允许机器人：名称=android.permission.SET_DEBUG_APP
    机器人：permissionGroup =android.permission，group.DEVELOPMENT_TOOLS
    安卓的ProtectionLevel =签名|系统|发展
    机器人：标签=@字符串/ permlab_setDebugApp
    机器人：说明=@字符串/ permdesc_setDebugApp/＆GT;

＆LT;！ -  @hide包检验需要有PackageManager在此之前的权限将
     信任它来验证软件包。
 - ＆GT;
＆LT;允许机器人：名称=android.permission.PACKAGE_VERIFICATION_AGENT
    机器人：标签=@字符串/ permlab_packageVerificationAgent
    机器人：说明=@字符串/ permdesc_packageVerificationAgent
    安卓的ProtectionLevel =签名|系统/＆GT;

如果有是XML块上的 @hide 注释，你找不到任何资源从大约此权限的文档。

When I do a dump of all permissions on all apps on a Nexus 7 I get (as expected) permissions with protection levels 0 (NORMAL), 1 (DANGEROUS), 2 (SIGNATURE). Nothing is logging under 3 (SIGNATURE_OR_SYSTEM)*.

But there are also a lot of permissions whose protection level is set at '18' and some that are '50'.

I can't find any documentation on what these values represent. Does anybody know?

*It's not logging anything under 3.

解决方案

Just saw an old unanswered question. Although you might already get your answer, I'll answer it anyway. It may help others. :)

there are also a lot of permissions whose protection level is set at '18' and some that are '50'.

The following code is retrieved from PermissionInfo.java in Android Source:

/**
 * Additional flag for {@link #protectionLevel}, corresponding
 * to the <code>system</code> value of
 * {@link android.R.attr#protectionLevel}.
 */
public static final int PROTECTION_FLAG_SYSTEM = 0x10;

/**
 * Additional flag for {@link #protectionLevel}, corresponding
 * to the <code>development</code> value of
 * {@link android.R.attr#protectionLevel}.
 */
public static final int PROTECTION_FLAG_DEVELOPMENT = 0x20;

So if there is a signature/system permission, the level would be 18(0x10 | 0x2). If the permission use used for special development tools, it would be 50(0x10 | 0x20 | 0x2).

I can't find any documentation on what these values represent. Does anybody know?

As I answered in an existing question, you can checked the protection level and the description of these permissions in framework/base/core/res/AndroidManifest.xml and framework/base/data/etc/platform.xml. I post some of them here for your reference.

<!-- Configure an application for debugging. -->
<permission android:name="android.permission.SET_DEBUG_APP"
    android:permissionGroup="android.permission-group.DEVELOPMENT_TOOLS"
    android:protectionLevel="signature|system|development"
    android:label="@string/permlab_setDebugApp"
    android:description="@string/permdesc_setDebugApp" />

<!-- @hide Package verifier needs to have this permission before the PackageManager will
     trust it to verify packages.
-->
<permission android:name="android.permission.PACKAGE_VERIFICATION_AGENT"
    android:label="@string/permlab_packageVerificationAgent"
    android:description="@string/permdesc_packageVerificationAgent"
    android:protectionLevel="signature|system" />

If there is a @hide annotation on that xml block, you cannot find any resources from documentation about this permission.
