兼容性：具有Android 2.2的应用程序能否在具有Android 2.0或2.1的手机上运行？

Question

I am using eclipse Hellios. My question is I am developing an application with Android 2.2, will it work on phones which have Android 2.0 or 2.1

Answer 1

It really depends on whether you're using parts of the API which were added after Android 2.0 or 2.1. The best way of ensuring that you only use compatible APIs specify Android 2.0 ( API Level 5) as your build target. By doing this, you will get compile time errors if you try and use APIs which are not available in 2.0.

Answer 2

如果其他版本（例如2.1和2.0）中不存在ApI的使用，则可能会出现问题。反之亦然。

Answer 3

取决于您在清单上定义为minSDKVersion的内容...如果API级别低于该值，则甚至不会安装...但是如果您不使用更高版本的API，则最好的选择是始终以1.5或1.6编译
