Multiple dex files error with signpost and gdata jars

Question

My app requires both signpost-core-1.2.1.2.jar and one of Google's libraries gdata-core-1.0.jar. But the signpost jar has some of the classes packaged in the gdata-core package. So, my app project is not building. Here is the error:

 Unable to execute dex: Multiple dex files define Lcom/google/gdata/util/common/base/Escaper;

How can I fix this conflict.. I need both the jars for different purposes within my app.

Answer 1

You can still keep two jars, but you would need to modify / repackage one of them to resolve runtime conflicts

• You need to decide what jar you will use for that conflicting class
• Open one of jars with 7zip (or alternative) and remove the path\to\Conflict.class file
• save the new jar
• update classpath to include new jar in your IDE
