屏幕大小是决定时所考虑的一个应用程序是否应在Android Market中出现的一个因素。

Screen sizes are just one factor that's taken into account when deciding whether an application should show up in Android Market.

在特别＆LT;使用特征＆GT; 在你的清单还可以引起你的应用程序标签，成为隐藏。即使你没有任何声明这些，某些＆LT;使用许可权方式＆gt; 标签可能会导致功能来获得所需的隐含

In particular, <uses-feature> tags in your manifest can also cause your application to become hidden. Even if you aren't declaring any of these, certain <uses-permission> tags can cause features to get implicitly required.

例如，如果要求 android.permission.CAMERA 许可， android.hardware.camera.autofocus 功能将自动获得必需的，除非你说，否则。不是所有的设备都有一个硬件的自动对焦，并且应用程序将无法在这些设备上显示。

For example, if you request the android.permission.CAMERA permission, the android.hardware.camera.autofocus feature will automatically get required unless you say otherwise. Not all devices have a hardware autofocus, and your application won't be shown on these devices.

此外，请记住，如果你有复制保护（又名着锁）启用，应用程序将无法在特定设备上显示出来。推荐的替代方案是使用Android授权服务：

Also, keep in mind that if you have copy protection (aka forward-locking) enabled, your application won't show up on certain devices. The recommended alternative is to use the Android licensing service:

（另外值得一提的是向前锁定将在数月内消失，所以你一定要看看，如果你关心这个许可服务。有关的博客文章，我联系到上面的更多信息。）

(It's also worth noting that forward-locking will be disappearing in a few months, so you definitely should look at the licensing service if you're concerned about this. See the blog post I linked to above for more information.)
