My project has fallen from a mistake conflict with "Duplicate entry Duplicate zip entry [commons-io-1.3.2.jar".
I has conflict with commons-io library and i spend one working day for find solution of problem.
I added function 'exclude' in gradle:
compile('net.yazeed44.imagepicker:imagepicker:1.3.0'){ exclude module: 'cam2' exclude group: 'commons-io', module: 'commons-io' }
