Turn: unable to execute DEX: Multiple Dex files define Solution

From: http://blog.csdn.net/mxlxiao7/article/details/8978930

 

Problem Overview:

The program is compiled normally. When eclipse is used for debugging and execution, the following error occurs: unable to execute DEX: Multiple Dex files define.

The specific solution is as follows:

In the project, the package name of a class is the same as the class in the referenced jar package. I use the class in the jar package, so this class in the project is referenced repeatedly, after you delete a class that is referenced repeatedly in the project, it is packaged and started. I hope you will pay attention to this small problem.
