Well

Every application exposes intent for launching that application.
So if you could try to generate the intent for the app you are working on, it 
should be possible.

Regarding SDCard, there is a MediaScanner service which scans the sdcard 
whenever it is inserted and the related Media Connection and Media Connection 
Client class (not sure of the exact names).
You will have to get a hook into MediaScanner service and try to generate your 
app's launching intent from there.

I am not absolutely sure if this can be done, but I think your best bet is to 
understand the MediaScanner service.

Subject: [android-developers] Portable application on SDcard

Hello,

I want to build an application which runs from the SD-card and saves
all the data on it. I mean I want the xml files, data base files and
native codes made by the application saved on the SDcard.
The aim is to have an SD-card which could be moved from a smart-phone
to another one with the embedded application and run on any smart-
phone without any particular operations?


Is it possible to made this kind of application?

Thank you,
Regards,

Kevin
