Hi guys,
Not sure if this is already documented but I have found the following...
Running the following command in the SDK against the emulator
SDK\bin>palm-install.bat <path to ipk file> --debug
causes the IPK file to be copied to /media/internal/developer/*
The --debug switch tells the device to not delete the IPK when the install fails.
The above command runs the following on the Pre itself
luna-send -i palm://com.palm.appinstaller/installNoVerify '{"target": "/media/internal/developer/FILENAME.ipk", "subscribe": true}'
It is palm://com.palm.appinstaller/installNoVerify which checks the validity of the IPK file so changing the SDK might not do it alone unless someone can find a new option instead of installNoVerify.
Running
SDK\bin>palm-install.bat <path to any file> --debug
will copy any file you want to /media/internal/developer.
This may be helpful too.
I will see what else I can find in com.palm.appinstaller.
Hope this helps
