我有一个使用众所周知的 对于传统应用程序 。它是建立在Android SDK 2.0清单设置的minSdkVersion =3（API 1.5）和targetSdkVersion =10（2.0）。 问题1：由于未指定maxSdkVersion时，应用程序应该是安装和compatable新近发布的Andr​​oid版本2.01和2.1是否正确？在这个时间点，我不打算将使用任何新的API功能，任何增强。 问题2：是有重建与Android SDK 2.1应用程序的任何价值？ 问题3：如果这样，应该targetSdkVersion从5（API 2.0）变更为图7（API 2.1）？

问题1：由于maxSdkVersion不  指定时，应用程序应该是  安装和compatable与新  发布的Andr​​oid版本2.01和2.1  是否正确？

正确的。

问题2：有没有任何价值  重建与应用程序  Android SDK中2.1？

不是真的，如果你不打算使用新事物。

问题3：如果是这样，应该  targetSdkVersion从5改变  （API 2.0）到7（API 2.1）？

在一般情况下，targetSdkVersion应该是你上测试您的应用程序的最新版本：

I have an Android application that uses the well known Strategies for Legacy Applications. It is build with the Android SDK 2.0 with manifest settings minSdkVersion="3" (API 1.5) and targetSdkVersion="5" (2.0). Question1: Since maxSdkVersion is not specified, the application should be installable and compatable with newly released Android versions 2.01 and 2.1 correct? At this point in time, I am not planning any enhancements that will use any new API features. Question2: is there any value in rebuilding the application with Android SDK 2.1? Question3: If so, should targetSdkVersion be changed from 5 (API 2.0) to 7 (API 2.1)?

Question1: Since maxSdkVersion is not specified, the application should be installable and compatable with newly released Android versions 2.01 and 2.1 correct?

correct.

Question2: is there any value in rebuilding the application with Android SDK 2.1?

not really, if you're not planning on using anything new.

Question3: If so, should targetSdkVersion be changed from 5 (API 2.0) to 7 (API 2.1)?

in general, targetSdkVersion should be the newest version you've tested your application on:
