使用aSpotCat控制您的Android应用权限

Viewing the permissions of each installed Android app requires digging through the Manage Applications screen and examining each app one by one — or does it? aSpotCat takes an inventory of the apps on your system and the permissions they require.

要查看每个已安装的Android应用程序的权限，需要深入浏览“管理应用程序”屏幕并逐个检查每个应用程序-还是吗？ aSpotCat会盘点系统上的应用程序以及它们所需的权限。

Permissions matter. Paying attention to them keeps malicious apps at bay, safeguards your privacy and protects your phone bill from unauthorized charges.

权限很重要。注意它们可以阻止恶意应用程序，保护您的隐私并保护您的电话账单免受未经授权的费用。

权限如何运作 (How Permissions Work)

Android requires each app ask for permissions to do things like send SMS messages, access your device’s storage or use the network connection. If an app is malicious — maybe it sends SMS messages to premium numbers and adds additional charges to your phone bill — the permissions screen will often clue you in.

Android要求每个应用程序都要求权限才能执行诸如发送SMS消息，访问设备的存储或使用网络连接之类的操作。如果某个应用程序是恶意软件-可能会将SMS消息发送给高级号码，并向您的电话账单添加了额外费用-权限屏幕通常会提示您。

Installing a game that wants permission to send SMS messages is generally a bad idea. To preserve your privacy and security, you shouldn’t install apps that require a lot of permissions with no obvious purpose. An app’s page on the Android Market will often say why it requires the permissions it does.

安装想要获得发送SMS消息权限的游戏通常是个坏主意。为了保护您的隐私和安全，您不应该安装需要大量权限且没有明显目的的应用程序。 Android Market上的应用页面经常会说出为什么需要它的权限。

Android如何呈现权限 (How Android Presents Permissions)

Android informs you of each app’s permissions when you install it. aSpotCat itself requires network access — it’s an ad-supported app, as is common on Android.

Android在安装时会通知您每个应用程序的权限。 aSpotCat本身需要网络访问权限-这是一个广告支持的应用程序，在Android上很常见。

If a developer adds more permissions to an app in an update, Android makes you install the update manually.

如果开发人员在更新中为应用程序添加了更多权限，则Android将使您手动安装更新。

If you want to view an individual app’s permissions after it’s installed, you can use the Manage Applications menu. Open the Settings screen, navigate to Applications -> Manage Applications, tap an application and scroll down. You’ll see the permissions required by the application.

如果要在安装后查看单个应用程序的权限，可以使用“管理应用程序”菜单。打开设置屏幕，导航至应用程序->管理应用程序，点击一个应用程序并向下滚动。您将看到该应用程序所需的权限。

按权限列出应用 (Listing Apps by Permissions)

aSpotCat is a free download from the Android Market. Once you’ve installed it, launch it and you’ll see its main menu.

aSpotCat是从Android Market免费下载的。安装后，启动它，您将看到它的主菜单。

The screen we’re really interested in is the “List apps by permission” screen. Tap it and you’ll see groups of permissions.

我们真正感兴趣的屏幕是“按许可列出应用程序”屏幕。点按它，您将看到权限组。

Tap a permission category to view the apps that use it. One of the main ones to watch is the “Services that cost you money” permission. Let’s tap that to view it.

点按权限类别以查看使用它的应用程序。要观看的主要内容之一是“花钱服务”许可。让我们点击以查看它。

If we wanted more information about what a specific permission category actually contained, we could tap the Details button. We can see that category contains apps that can call phones and send SMS messages, so it’s obvious why AirDroid, which can send SMS messages, and Skype, which can call phones, are here.

如果需要有关特定权限类别实际包含的内容的更多信息，可以点击“详细信息”按钮。我们可以看到该类别包含可以拨打电话和发送SMS消息的应用程序，因此很明显，为什么可以发送SMS消息的AirDroid和可以拨打电话的Skype出现在这里。

Tap each subcategory to see a further breakdown of permissions. You can also tap the stars here to “bookmark” a permission; bookmarked permissions appear in the “List apps by bookmarks” screen.

点击每个子类别以查看权限的进一步细分。您也可以点击此处的星标以“标记”权限；带有书签的权限显示在“按书签列出应用程序”屏幕中。

Dig further into other categories of permissions and you may be rather surprised. It’s disappointing how many games — Angry Birds, anyone? — require permission to track your physical location, presumably for advertisement targeting.

进一步研究其他类别的权限，您可能会感到很惊讶。令人失望的是有多少场比赛-愤怒的小鸟，有人吗？ -要求获得许可以跟踪您的实际位置，大概是为了广告定位。

其他屏幕 (Other Screens)

From the “List apps” screen, you can view apps individually and see exactly what permisisons they require. You can also access this information by tapping an app’s icon in the “List apps by permission” screen.

在“列出应用程序”屏幕上，您可以单独查看应用程序，并确切查看它们所需的权限。您还可以通过点击“按权限列出应用程序”屏幕中的应用程序图标来访问此信息。

If you’re particularly worried about a specific permission, you can bookmark it from its Details screen. Use the “List apps by bookmarks” screen to see only the permissions you’ve bookmarked.

如果您特别担心特定的权限，可以在其“详细信息”屏幕中为其添加书签。使用“按书签列出应用程序”屏幕，以仅查看已添加书签的权限。

aSpotCat is no substitute for keeping an eye on permissions when you install apps, but it’s a great way to do a quick survey of permissions. If you find an app that seems to require too many permissions, you may want to look for an alternative that requires less.

在安装应用程序时，aSpotCat不能代替关注权限，但这是快速调查权限的好方法。如果发现似乎需要太多权限的应用程序，则可能需要寻找需要更少权限的替代方案。
