我发现这篇帖子谈到了这个错误：noclassdeferror for inner class MyLicenseCheckerCallback
但它没有帮助我。我尝试了干净的项目，添加google play license作为jar（在构建路径中）文件。 什么都没有帮助...
可能是什么问题？
答案 0 :(得分：0)
你可以试试这个.. 右键单击Project - ＆gt; build Path - ＆gt; Configure Build Path - ＆gt; java build path - ＆gt; order and export tab - ＆gt; check check on jar - ＆gt; click ok
现在清理项目
答案 1 :(得分：0)
我有完全相同的例外，上述建议均不适合我。
然而，通过确保您的LVL项目是一个图书馆项目（右键单击项目 - ＆gt;属性 - ＆gt; android 并勾选“Is Libary”checkbo），我得到了我的工作。
要在您的应用程序项目中包含它，请删除对此的任何其他引用并应用更改。然后，如果还没有导航到（右键单击应用程序项目 - ＆gt;属性 - ＆gt; android ），并在库部分单击添加并选择您的LVL项目。应用更改。好又干净的项目。
希望这有助于某人。
