计算7.0版Android权限数量的最准确方法是什么？

根据我在网上的研究，我发现要计算最新版本Android（Android 7）的许可数量，我们可以参考此链接中建议的官方文档（）

建议的表包含138个权限，在我使用github（）上的这个小解析程序扫描Android操作系统的AndroidManifest.xml（）文件分析之前，我认为我的计数是正确的

生成的输出文件包括：

android.permission-group.CONTACTS:
3 Permissions
android.permission.READ_CONTACTS
android.permission.GET_ACCOUNTS
android.permission.WRITE_CONTACTS

如您所见，检测到的权限数量远远超过文档中引用的数量，AndroidManifest.xml中列出了权限，但文档中不存在这些权限，例如：android.permission.ALLOW\u ANY\u CODEC\u for\u PLAYBACK，android.permission.ACCESS\u FM\u RADIO

我的分析有什么错误？我最终想要的是Android 7中向开发者提议的权限数量，是138个还是更多？如果更多，如果我基于AndroidManifest.xml文件，如何计算它们

谢谢你的帮助

我最终想要的是Android 7中向开发者提议的权限数量，是138个还是更多

不清楚您所说的“向开发人员提议的许可数量”是什么意思

如果您的意思是“安卓7.0设备上定义的权限数”，那么答案是

”\_(ツ)_/“

，因为应用程序可以定义自己的权限

如果您的意思是“安卓7.0设备上定义的出厂许可数量”，答案是

”\_(ツ)_/“

，因为制造商的预装应用程序可以定义自己的权限

如果您的意思是“安卓7.0设备上定义的权限数量（出厂时提供），不包括预装应用程序的权限数量”，那么答案是

”\_(ツ)_/“

，由制造商（或自定义ROM开发人员）修改

如果您的意思是“Android 7.0版Android开源项目中定义的权限数量，不包括任何AOSP应用程序之类的设置”，那么平台

AndroidManifest.xml

文件中的

元素数量至少是300个。现在，这是300多个（根据

主机

分支，我的计数是353）

如果你的意思是“在安卓7.0上工作的普通应用程序开发人员将处理的权限数量”，这将是

Manifest.permission

JavaDocs中记录的权限，它将是平台

AndroidManifest.xml

文件中定义的权限的一小部分。例如，

ACCESS\u FM\u RADIO

是您引用的在清单中但不在文档中的权限，这是因为它具有

@隐藏

注释：

<!-- @SystemApi Allows access to FM
     @hide This is not a third-party API (intended for system apps).-->
<permission android:name="android.permission.ACCESS_FM_RADIO"
    android:protectionLevel="signature|privileged" />

在平台Java类中，

@hide

-注释的元素作为构建

android.jar

的一部分从SDK中删除。类似地，

@hide

-注释的清单元素也从SDK中删除，即使它们应该存在于设备上

---

FWIW使用

PackageManager

查找Android设备上所有已定义的权限，并根据保护级别在选项卡中列出它们。因此，例如，

ACCESS\u FM\u RADIO

在Android 7.1.1设备上显示。

我认为您可以创建允许开发人员使用的权限组及其权限的列表elopers（因此应记录在案），使用以下代码：

fun checkPermissions() {
    val allPermissionGroups = packageManager.getAllPermissionGroups(0)
    var permissionsCount = 0
    for (permissionGroup in allPermissionGroups) {
        val permissionGroupName = permissionGroup.name
        if (!permissionGroupName.startsWith("android.permission-group."))
            continue
        Log.d("AppLog", "permissionGroup:$permissionGroupName:")
        val permissions = packageManager.queryPermissionsByGroup(permissionGroupName, 0)
        for (permission in permissions) {
            if (!permission.packageName.startsWith("android") ||
                    (permission.protectionLevel and PermissionInfo.PROTECTION_SIGNATURE) != 0)
                continue
            Log.d("AppLog", " $permission")
            ++permissionsCount
        }
    }
    Log.d("AppLog", "total permissions count:$permissionsCount")
}

例如，在Android p（API 28）上运行它，我发现它有30个权限：

permissionGroup:android.permission-group.CONTACTS:
 android.permission.WRITE_CONTACTS
 android.permission.GET_ACCOUNTS
 android.permission.READ_CONTACTS
permissionGroup:android.permission-group.PHONE:
 android.permission.ANSWER_PHONE_CALLS
 android.permission.READ_PHONE_NUMBERS
 android.permission.READ_PHONE_STATE
 android.permission.CALL_PHONE
 android.permission.ACCEPT_HANDOVER
 android.permission.USE_SIP
 com.android.voicemail.permission.ADD_VOICEMAIL
permissionGroup:android.permission-group.CALENDAR:
 android.permission.READ_CALENDAR
 android.permission.WRITE_CALENDAR
permissionGroup:android.permission-group.CALL_LOG:
 android.permission.READ_CALL_LOG
 android.permission.WRITE_CALL_LOG
 android.permission.PROCESS_OUTGOING_CALLS
permissionGroup:android.permission-group.CAMERA:
 android.permission.CAMERA
permissionGroup:android.permission-group.SENSORS:
 android.permission.BODY_SENSORS
 android.permission.USE_FINGERPRINT
 android.permission.USE_BIOMETRIC
permissionGroup:android.permission-group.LOCATION:
 android.permission.ACCESS_FINE_LOCATION
 android.permission.ACCESS_COARSE_LOCATION
permissionGroup:android.permission-group.STORAGE:
 android.permission.READ_EXTERNAL_STORAGE
 android.permission.WRITE_EXTERNAL_STORAGE
permissionGroup:android.permission-group.MICROPHONE:
 android.permission.RECORD_AUDIO
permissionGroup:android.permission-group.SMS:
 android.permission.READ_SMS
 android.permission.RECEIVE_WAP_PUSH
 android.permission.RECEIVE_MMS
 android.permission.RECEIVE_SMS
 android.permission.SEND_SMS
 android.permission.READ_CELL_BROADCASTS
total permissions count:30

编辑：

出于某种原因，我可以在这里看到“READ\u CELL\u BROADCASTS”，它没有文档记录。不知道它是什么

编辑：从一些Android版本开始（我认为Android 10-API29），您无法获得哪个权限属于哪个权限组

编辑：权限组及其权限（至少对于英语语言环境）的代码如下：

---

这些是sdk中没有公开的私有权限。所有的公共权限都是@所以根据我的理解，当我们说X版本的Android提供Y权限时，我们只谈论公共权限，对吗？这意味着我的第一个计数是正确的：Android 7只提供138个权限“当我们说Android的X版本提供Y权限时”——这完全取决于“我们”是谁。无论“我们”是谁，都应该更准确。@commonware“我们”代表普通应用程序开发人员，您下面的答案非常清楚，谢谢；）太好了！谢谢你这么说OK，很清楚，所以如果我们分析Google Play中发布的所有Android应用程序中包含的所有AndroidManifest文件，我只能在Manifest.permission JavaDocs中找到有文档记录的权限，对吗？@J.Adam：“我只能在Manifest.permission JavaDocs中找到有文档记录的权限“--这有点重复（“我只能在文档中找到有文档记录的东西”）。但是，是的，对于普通的应用程序开发人员来说，JavaDocs中记录的东西才是最重要的。@commonware我认为我需要编写一些代码来列举（Android框架有文档记录）开发者可以使用的权限。写在这里的另一个答案上。你认为它是正确的吗？结果似乎很有希望…@androiddeveloper:代码就其本身而言是很好的，尽管我不认为它一定会反映出你可能认为它的功能。好吧，设备制造商可以将自己的权限放在

andr中OID。许可组。< /代码>，例如前缀组。希望，很少有。如果你的目标是“在几个设备上运行同一API级别，并考虑所有的共同点”，这是合理的。但是我不会假设一个单独的设备保证这个算法可以限制你在API文档中的权限。
