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.

要查看每個已安裝的Android應用程序的權限，需要深入瀏覽“管理應用程序”屏幕并逐個檢查每個應用程序-還是嗎？ aSpotCat會盤點系統上的應用程序以及它們所需的權限。

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

權限很重要。 注意它們可以阻止惡意應用程序，保護您的隱私并保護您的電話賬單免受未經授權的費用。

權限如何運作 (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要求每個應用程序都要求權限才能執行諸如發送SMS消息，訪問設備的存儲或使用網絡連接之類的操作。 如果某個應用程序是惡意軟件-可能會將SMS消息發送給高級號碼，并向您的電話賬單添加了額外費用-權限屏幕通常會提示您。

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.

安裝想要獲得發送SMS消息權限的游戲通常是個壞主意。 為了保護您的隱私和安全，您不應該安裝需要大量權限且沒有明顯目的的應用程序。 Android Market上的應用頁面經常會說出為什么需要它的權限。

Android如何呈現權限 (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在安裝時會通知您每個應用程序的權限。 aSpotCat本身需要網絡訪問權限-這是一個廣告支持的應用程序，在Android上很常見。

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

如果開發人員在更新中為應用程序添加了更多權限，則Android將使您手動安裝更新。

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.

如果要在安裝后查看單個應用程序的權限，可以使用“管理應用程序”菜單。 打開設置屏幕，導航至應用程序->管理應用程序，點擊一個應用程序并向下滾動。 您將看到該應用程序所需的權限。

按權限列出應用 (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是從Android Market免費下載的。 安裝后，啟動它，您將看到它的主菜單。

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

我們真正感興趣的屏幕是“按許可列出應用程序”屏幕。 點按它，您將看到權限組。

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.

點按權限類別以查看使用它的應用程序。 要觀看的主要內容之一是“花錢服務”許可。 讓我們點擊以查看它。

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.

如果需要有關特定權限類別實際包含的內容的更多信息，可以點擊“詳細信息”按鈕。 我們可以看到該類別包含可以撥打電話和發送SMS消息的應用程序，因此很明顯，為什么可以發送SMS消息的AirDroid和可以撥打電話的Skype出現在這里。

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.

點擊每個子類別以查看權限的進一步細分。 您也可以點擊此處的星標以“標記”權限； 帶有書簽的權限顯示在“按書簽列出應用程序”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.

進一步研究其他類別的權限，您可能會感到很驚訝。 令人失望的是有多少場比賽-憤怒的小鳥，有人嗎？ -要求獲得許可以跟蹤您的實際位置，大概是為了廣告定位。

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“列出應用程序”屏幕上，您可以單獨查看應用程序，并確切查看它們所需的權限。 您還可以通過點擊“按權限列出應用程序”屏幕中的應用程序圖標來訪問此信息。

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.

如果您特別擔心特定的權限，可以在其“詳細信息”屏幕中為其添加書簽。 使用“按書簽列出應用程序”屏幕，以僅查看已添加書簽的權限。

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.

在安裝應用程序時，aSpotCat不能代替關注權限，但這是快速調查權限的好方法。 如果發現似乎需要太多權限的應用程序，則可能需要尋找需要更少權限的替代方案。
