将片段用于常用的UI元素。实施了一个简单的POC来检查它的工作情况。但是当我整合到我的主项目时，它会给运行时错误（崩溃）
这是我的Androidmainfiest.xml

我的项目中包含其他库文件： * facebook android SDK *谷歌播放服务 * android支持jar 4
感谢您的时间

检查您的导入声明。
正如你所说，你的MIN SDK版本是8。
这些陈述不起作用;
import android.app.Fragment;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
要获得SDK vesion的片段支持，您需要导入这些语句
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
