Re: Applications spawning other Applications

 

I agree. A pluggable architecture (like Android's Intents) would be better
than hard coding.

I really like a MIME type only approach for this because that makes apps
pluggable. If you for example have an app called barcode scanner for
scanning
barcodes and a shopping app called price checker that can use barcode
scanner
to scan barcodes to scan a products barcode and see where it's cheapest.

Now a new app releases called qr code scanner that can do the same thing but
I for one reason or another preffer this one over barcode scanner a MIME
type
approach lets me use the app I prefer if qr code scanner implements the
same API.
But with a app name/id/path approch I would have to use barcode scanner if
that's
what price checker were designed for.

Of cource all apps needs to be able to register new MIME types. If you have
multiple
apps that support the same MIME type one popup should appear letting you
choose
which one to use.
