android - NoClassDefFoundError : com/google/common/base/Predicate when importing MonkeyRunner in Jython

Question

我想使用 MonkeyRunner 生成 MotionEvent(从屏幕触摸)。我已经阅读了有关的信息 http://developer.android.com/guide/developing/tools/monkeyrunner_concepts.html .

问题是对于这个 jython 程序:

from com.android.monkeyrunner import MonkeyRunner

if __name__ == '__main__':
   # Connects to the current device, returning a MonkeyDevice object
   device = MonkeyRunner.waitForConnection()

执行时出现以下错误:

Traceback (most recent call last):
  File "C:\Documents and Settings\jjungb00\python\workspace\monkey\src\runner.py",     line 6, in <module>
    from com.android.monkeyrunner import MonkeyRunner

...跳过一些堆栈跟踪...

我已经从 android sdk 工具/lib 添加了 monkeyrunner.jar 作为外部库。我在 XP 上运行，使用 jython 2.5.2。

知道要做什么吗？我想我必须添加另一个库，但我不知道在哪里或哪个库。

您需要添加 Google 集合库 - 目前重命名为 Guava。在android SDK目录下寻找guavalib.jar。
