Android权限组的内容

Question

Android拥有不同的权限组和权限。每个权限组代表特定的权限。但是我找不到每个组所拥有的权限列表。它在任何地方发布？

例如， android.permission.ACCOUNT_MANAGER与权限组ACCOUNTS关联。 我需要这种关联的列表。

Answer 1

可以使用PackageManager getAllPermissionGroups（）和queryPermissionsByGroup（） 来枚举整个Android权限层次结构。下面的代码在5.1.1（SDK 22）设备的末尾生成了输出结果。标记为“个人”的组具有groupInfo.flags == 1，并且看起来与在棉花糖中被称为“危险”的权限组相对应。

由于SDK级别的差异以及应用程序可以定义自定义权限的事实，您将在不同设备上获得不同的权限层次结构。

/** 
* Uses PackageManager getAllPermissionGroups() and queryPermissionsByGroup() 
* to enumerate the Android permission hierarchy. 
*/ 
private void showPermissionTree() 
{ 
    final PackageManager pm = m_context.getPackageManager(); 
    if (pm == null) 
     return; 

    /* 
    * Get a list of all permission groups and sort them alphabetically. 
    * Then add to the end of the list the special case of a null group name. There can be 
    * numerous permissions that are not listed under a group name. 
    */ 
    List<PermissionGroupInfo> groupInfoList = pm.getAllPermissionGroups(0); 
    if (groupInfoList == null) 
     return; 

    ArrayList<String> groupNameList = new ArrayList<>(); 
    for (PermissionGroupInfo groupInfo : groupInfoList) { 
     String groupName = groupInfo.name; 
     if (groupName != null) { 
      if (Build.VERSION.SDK_INT >= 17) { 
       /* 
       * SDK 17 added the flags field. If non-zero, the permission group contains 
       * permissions that control access to user personal data. 
       * N.B. These are the permissions groups that are called "dangerous" in 
       * Marshmallow. 
       */ 
       if (groupInfo.flags != 0) { 
        groupName += " (personal)"; 
       } 
      } 
      groupNameList.add(groupName); 
     } 
    } 

    Collections.sort(groupNameList); 
    groupNameList.add(null); 

    /* 
    * Loop though each permission group, adding to the StringBuilder the group name and 
    * the list of all permissions under that group. 
    */ 
    StringBuilder sb = new StringBuilder(10000); 
    final String INDENT = " "; 

    for (String groupName : groupNameList) { 
     if (groupName == null) 
      groupName = "null"; 

     sb.append("* ").append(groupName).append("\n"); 

     ArrayList<String> permissionNameList = getPermissionsForGroup(groupName); 
     if (permissionNameList.size() > 0) { 
      for (String permission : permissionNameList) { 
       sb.append(INDENT).append(permission).append("\n"); 
      } 
     } else { 
      sb.append(INDENT).append("no permissions under group\n"); 
     } 

     sb.append("\n"); 
    } 

    m_textView.setText(sb.toString()); 
} 


/* 
* Gets and returns a list of all permission under the specified group, sorted alphabetically. 
* 
* N.B. groupName can be null. The docs for PackageManager.queryPermissionsByGroup() say 
* "Use null to find all of the permissions not associated with a group." 
*/ 
private ArrayList<String> getPermissionsForGroup(String groupName) 
{ 
    final PackageManager pm = m_context.getPackageManager(); 
    final ArrayList<String> permissionNameList = new ArrayList<>(); 

    try { 
     List<PermissionInfo> permissionInfoList = 
       pm.queryPermissionsByGroup(groupName, PackageManager.GET_META_DATA); 
     if (permissionInfoList != null) { 
      for (PermissionInfo permInfo : permissionInfoList) { 
       String permName = permInfo.name; 
       if (permName == null) { 
        permName = "null"; 
       } else if (permName.isEmpty()) { 
        permName = "empty"; 
       } 
       permissionNameList.add(permName); 
      } 
     } 
    } 
    catch (PackageManager.NameNotFoundException e) { 
     // e.printStackTrace(); 
     Log.d(TAG, "permissions not found for group = " + groupName); 
    } 

    Collections.sort(permissionNameList); 

    return permissionNameList; 
}

Android权限列表here和权限组here。然后还可以看看PemissionInfo()。
