Android Question Getting results from common activities

[nibbo]

Hi All

I have built an app that I want to use as a common activity in several other apps.
Is using JavaObject and StartActivityForResult as per this thread https://www.b4x.com/android/forum/threads/using-startactivityforresult-with-javaobject.40374/ still the best way?
I ask because this is a pretty old thread but I cannot seem to find any other way to do this?

Can I use 'Wait For' to wait until the activity completes?

Thanks
Nibbo

It was never the best idea for interacting with your activities.

Why do you need to have a common activity and not a common class? It will make things simpler.

Hi Erel

I have several warehouse apps running on rugged handhelds with built in barcode readers that all need to scan Stock Barcodes and Location QR Codes.
There is a UI associated with this also so it does need to be an activity; correct me if I am wrong...
Having it in a single app means that I only need to change it once should the requirements change in any way.
It also means that I have the scanner service wrapped up in a single app and only need to mess about with one manifest if we start using different hardware/scanners etc.

Thanks

This is wrong. You can use the same activity and implement parts of the UI in a class.

Anyway, you can call other activities with CallSubDelayed. You can pass Me to the other activity and then call it back with another CallSubDelayed.

Thanks Erel, unfortunately I don't think my level of expertise extends to this just yet and I don't really have the time to experiment.
I have got it working with StartActivityForResult but may revisit it again later if time permits; which I doubt... Ta
