解决方案

属性的android：parentActivityName 在API 16介绍设置项目的构建目标至Android 4.1那么你就可以运行你有API级别14设备上的应用程序（您申报的最低水平SDK是14）或者更高的水平，如果Android的支持库包含在项目的构建路径。

i've included the android-support-v4.jar library to use "android:parentActivityName="com.myApp.example.MainActivity". It's included in "Android" Dependencies" and "Referenced Libraries", but it still doesn't work ->

error: No resource identifier found for attribute 'parentActivityName' in package 'android'

Any suggestions?

解决方案

The attribute android:parentActivityName is introduced in API 16. Set your project's build target to Android 4.1 and then you can run your app on the devices that have API level 14(you declared minimum sdk level to be 14) or higher levels if android support library is included in your project's build path.
