今天我开始观察一些新的错误，它不允许我在Eclipse中创建一个新的Android应用程序。它显示“更新工具”，您的工具安装似乎已过时。此向导取决于随Android SDK工具分发的模板....“
我有android 2.2 API 8，我认为当我开始工作时它是稳定的。有人可以建议我这个错误是什么？或者我是否需要更新到Android 4.1 API 16？现有项目是否会在该版本上运行？
以下是我尝试更新到2.3.3时的错误：

将targetSdkVersion设置为最新的（当前为16），并将其设置在project.properties文件中。这将允许您的应用程序针对最新的Android版本进行优化，并允许您使用最新的类和功能。您还可以获得更全面的API javadoc和更多常量。
当然，您需要知道，如果您使用仅在新版本上受支持的功能或类，该应用程序将粉碎旧版本。常量可以安全使用，因为它们被转换为简单的字符串和值。
这就是为什么你应该在发布应用程序之前运行Lint，以确保不会发生这样的事情。

您可以安全地更新Android SDK工具，并且仍然支持Android 2.2（API 8）。下载SDK工具后，您可以选择要开发的平台，也可以选择API 8.您为Android 2.2开发的任何内容都适用于Android 4.1。
