transformClassesWithDexForDebug

Android Studio运行出现Bug

运行时候，Android Studio运行爆出错误transformClassesWithDexForDebug

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.7.0_80\bin\java.exe'' finished with non-zero exit value 2

这种错误一般是包冲突或者jar冲突导致的，去检查下build.gradle，工具会提醒错误

因为v13包已经包含v4包了，所以我们把v4包去掉
