Android Oracle数据库JDBC6
您好我想创建一个到我的Oracle数据库的连接。 我以前使用ojdbc14.jar，一切正常，但连接应该是安全的，我想加密文件。 所以我现在决定使用ojdbc5.jar。 jar是我的“libs”文件夹
从jdbc14更改为jdbc6的原因我想使用Properties在我的数据库和我的设备之间进行安全的数据交换
早些时候我也试过jdbc5但是这个我只有一个java Heap Size错误。

Android的Java与Oracle的Java不同。 其中一个主要区别是类库与Java标准版（SE）不同。
在您的情况下，这意味着ojdbc6.jar将无法在Android的Java环境中运行，因为某些Java SE类是必需的，但在Android上不可用。 错误消息提到javax.management.MBeanServer 。 但我很确定这不是唯一的。
我不认为你可以让ojdbc6.jar在Android上运行。 ojdbc14.jar工作已经令人惊讶了。 所以请坚持下去，或重新设计您的应用程序，以通过中介服务器。
