Sensetive ProgressBar - Retrofit

[umtblbl]

I want to change the save button to show the download status instantly when the user clicked the "save" button in the image upload process in the Android application. In other words, when the upload is complete, the "save" button will show progress and the okey button will appear when the upload is complete.

What kind of structure do I have to use for this? I've searched, but I guess I'm not a complete solution because I'm a beginner. Do you have a library, video tutorial or a suggestion?

I using this tutorial and it works fine to me.

It is using Retrofit, JobIntentService, Broadcast Receiver, and Notification Service. The uploading progress will be shown as notification.
