android : Error converting byte to dex

Question

So, I am getting the following error while running the project after upgrading build.gradle (Project) from

dependencies {
        classpath \'com.android.too         


        

Answer 1

This problem is mainly in gradle or in misversioned libraries, including, from libraries, when both define the same class. Expand and check, imported external libraries...

You cannot have two same classes to be exported to one place, or code, therefore, dexer does not know which one should be used...
