Android：添加的依赖关系使Gradle中出现DEX错误。

Question

I am working on an Android application in which i am trying to get Cometd(Push technology) working. For that I added some Gradle dependencies, but I am getting a DEX error. How can I resolve this?

Kindly let me know what I should do. Thanks a lot. :-)

Answer 1

defaultConfig {
         minSdkVersion 14 //lower than 14 doesn't support multidex
         targetSdkVersion 22

         // Enabling multidex support.
         multiDexEnabled true
     }
