Java Android因引用/实现接口而崩溃

我是来自Java背景的Android新手。所以，如果这是一个非常简单的修复，请原谅。我用java创建了一个机器仿真器，我想用一个简单的UI在Android上运行它。问题是当我这样做的时候它崩溃了

 public class UITerminal extends EditText implements Terminal

我也在课堂上试过这个

 Terminal terminal;
 public void init()
 {
      terminal = new Terminal()
      {
         //implemented methods
      }
 }

这两种解决方案在开放时都崩溃了。对我应该怎么做有什么建议吗？提前谢谢。这是我第一次体验Android

编辑

我点击应用程序，它显示“不幸的是MyTronEmulator已经停止工作”

---

除了将其添加为库之外，还必须确保IDE正在导出.jar文件。否则，假定它已经在电话/模拟器上

---

在eclipse中，您可以通过右键单击项目->构建路径->配置构建路径->订单和导出->检查库来确保这一点。

这是很久以前的事了，但我尝试使用Java 1.7库。Android最多只支持1.6版本

---

我希望错误只是这样说：）

发布崩溃的日志，即“崩溃”？我将.jar文件添加为库，它编译得很好。我做到了。我将库添加到lib文件夹下，然后将jar作为文件添加，并选中“顺序和导出”框。@TylerDavis您是否尝试过清理（Project->clean）项目并重新构建？尽管我确实认为我的问题是jar没有导出到emulator
