Remove persistent groups #117

Closed brendankirby closed 8 years ago

brendankirby commented 8 years ago

Uses Java reflection to remove persistent/remembered groups.

It was pretty simple, just copy and pasted this method and it worked.

I still want to figure out why they don't let you call the method.

Hi Brendan,

Just curious, when you find a solution like this, do you put the information and example into a separate document that supports/describes your new library or is there another way in which you keep track of this descriptive background information?

@cghiee Hi Clark, that's a good point. I thought I would be able to figure out how to call the real method eventually, but I got an answer in the Google Group and it doesn't seem like there's much I can do besides reflection. So I'll cite this in the code and discuss it in our FAQ's doc.

"That API is not in the SDK.

This is a general Android paradigm .. it often exposes a subset of APIs in SDK than what the OS natively implements. There are various reasons for it .. including system stability, security etc. The most prominent reason for hidden APIs is that Android reserves right to change it and break your apps.

That said, there are some APIs here that need to be added or improved or exposed - as you are correct to point out. Short of changing Android, it is hard to do. Till then, we are limited to using what the system provides."
