Android的：如何保持向后兼容？ [英] Android: How to maintain backwards-compatibility?

问题描述

根据指示找到这里，让您的应用状态，这屏幕大小可以支持，你需要编写你的应用程序对Android 1.6的。

According to the instructions found here, to make your app state which screen sizes you can support, you'll need to compile your app against Android 1.6.

使用的minSdkVersion和targetSdkVersion这应该在Android 1.5还运行：

Using the minSdkVersion and targetSdkVersion this should run also on Android 1.5:

  <uses-sdk android:minSdkVersion="3" 
          android:targetSdkVersion="4"/>

然而，当我尝试推出从Eclipse的我的应用程序在一个模拟1.5上运行，我收到以下错误：

However, when I try to launch my app from Eclipse to run in a emulated 1.5, I get the following error:

 Failed to find an AVD compatible with target 'Android 1.6'.

这是Eclipse工具/仿真器的错误？或者，我怎么得到它也瞄准1.5正确而给我指定支持屏幕的选项？

Is this an error of the eclipse tools/emulator? Or how do I get it to also target 1.5 correctly while giving me the option to specify the supported screens?
