@wajahatali5 Hi, Are you close the "Offline work" setting?

[wajahatali5]

@zhengxiaopeng Hi, No, my application is totally work on rest API's.

@wajahatali5 "Offline work" is the AS's gradle setting, search "Offline work" in your AS setting and close it if the setting is enable. Your error seem to cause by gradle work on offline model. Or jcenter doesn't included in your project's build.gradle(root path) file. See like this file: https://github.com/zhengxiaopeng/BounceProgressBar/blob/master/build.gradle
