Android Tip: Unable to execute dex:multiple Dex files define Solution

Well, I've thought about not moving Android in the future, but I didn't think it was the reason for the game. Many of the problems with Android are due to eclipse's imperfections, such as the one encountered today unable to execute Dex:multiple Dex files define

[2011-10-23 16:23:29-dex Loader] Unable to execute Dex:multiple Dex files define Lcom/myapp/r$array;
[2011-10-23 16:23:29-myproj] Conversion to Dalvik format failed:unable to execute dex:multiple Dex files define Lcom/myapp/r$array;

Well, the cause of this problem is that everyone should have a different problem, but it's all because of the Eclipse compiler, which can refer to two articles (1.http://blog.csdn.net/asan855/article/details/ 7568702 2.http://stackoverflow.com/questions/7870265/ Unable-to-execute-dex-multiple-dex-files-define-lcom-myapp-rarray)

Here's what I think and the solution:

Reason one: Because there is a problem with APK compilation

WORKAROUND: Delete the bin file directly, eclipse will be automatically generated for you at compile time, and if not, restart Eclipse

Reason two: Duplicate package name

WORKAROUND: There are two possible ways to duplicate package names.

1, one of the two jar names, in the Lib can look, if there is the same delete a.

2. This situation is to be noted. Sometimes the jar name is different, but it will also report this error, because the two jar inside the package name has the same. This requires that we open the jar to see if the package name is duplicated.

The following figure is Android_services_2.2.0.jar, and Android_location_v1.1.2.jar, and the two have no identical packages.

Some thinking: When doing a program, encounter bugs or to understand the principle of their own to find ways, like the second I mentioned above the situation, StackOverflow in fact also did not account for, some things still want to think, do not blindly search the Internet to find the answer, especially in the operation of the egg pain of Android.
