Question

有两个项目：My project和Library project。

我已在Android工作室中导出Android library project to jar file successfully, built from aar to jar。

现在，我将jar放入my project以允许将其用作库。

清洁后＆amp;同步gradle成功。 My project可以理解jar库中的类是否正确。

但是在发布之后，它仍然会崩溃并且低于与jar library相关的异常，

我不知道为什么，

知道的人，请告诉我如何解决，

谢谢，

p / s：实际上，我尝试将jar库发布到maven，所以我需要在发布之前进行测试。

如果我没有声明活动CustomCamera和CustomGallery，我将崩溃并获取异常，而不是在manifest.xml中声明活动。

异常

尝试放入libs文件夹并将其添加为库 - ＆gt;不行。
