Error:Execution failed for task ':app:transformClassesWithDexForDebug'. > com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.Exec

出现这种情况只需要在build里面添加上

  dexOptions {
        javaMaxHeapSize "4g"
        preDexLibraries = false
    }

就会完美解决 如有什么疑问 欢迎咨询!
