Java / Android / Eclipse：IllegalArgumentException：已经添加

Question

我的Eclipse环境中有一个Java项目“ EDNA ”，它使用名为 libosm 和 osmnavigation 的库。

我将包含 libosm 和 osmnavigation 的“ EDNA ”导出到jar中。 EDNA.jar会在我的Android 2.2项目“ Tableted ”中导入（复制到libs文件夹）。 libosm 和 osmnavigation 会自动添加：

Tableted 在“Java Build Path - ＆gt; Projects”中没有设置任何内容。 “Java Build Path - ＆gt; Libraries”看起来像这样：

当我点击Debug时，会发生以下错误：

我还尝试引用该项目，而不是添加jar。但这会导致同样的错误。

Answer 1

它们是否已添加并标记在“订单和出口”标签下？
否则试试这个，这是一个普遍的问题，在我的意见红色中，它不能正确导出它们。
