Can't toast on a thread that has not called Looper.prepare() #668

Open cristmasbox opened 5 months ago

I'm working on an app which should download some files, but allways if i try it it gets this Error from the FetchListener:

java.lang.NullPointerException: Can't toast on a thread that has not called Looper.prepare()

I have checked, all inputs aren't null and I can't find a solution. Can anyone help me?
