好了，所以这并没有真正有很多工作要做，code的帮助，但我刚开始我的最后一年的项目，将pferably开发$ P $为Android移动设备。该计划是在Android 2.1的创建它，因为我只有一个使用HTC Hero的，但我的测试人员版机器人的组合。并没有多少有一个新的HTC One或新的Nexus，所以我presume它们都使用旧版本的操作系统。

Okay so this doesn't really have much to do with code help but I am just starting my final year project and will be developing preferably for Android mobile devices. The plan is to create it in Android 2.1 as I only have a used HTC hero but my testers have a mix of version androids. and not many have a new HTC One or new Nexus, so i presume that they are all using older versions of the OS.

因此​​，我需要知道的是，我将能够在2.1创建应用程序，并将其操作系统的新版本上运行（preferably手机不是平板电脑，如果它很重要）？

So what I need to know is, will I be able to create the application in 2.1 and it run on new versions of the OS (preferably phones not tablets, if it matters)?

推荐答案

是的，你绝对可以！与无的问题，据我所知。

Yes, you absolutely can! No issues with that, as far I know.

当你正在构建应用程序，在你申报清单文件中的 的minSdkVersion ，指定运行应用程序所需的最低Android操作系统版本。您的应用程序可以运行在所有高于或完全规定的最低SDK版本。

When you are building your application, in the Manifest file you declare the MinSDKVersion which specifies the minimum Android OS version needed to run your application. Your application will run on all devices which are above or exactly the minimum SDK version specified.

目前是它可以运行你的应用程序的最高版本没有限制。

There is no limit on the maximum version which can run your application.
