I'm wondering if there is any way for an external app to launch ODK Collect, but into a new instance of a specific form. Not into the main menu or 'select a form' menu.
Similarly, I am also wondering if it is possible to, at the end of a form, send its data to an external app instead of a server or system running briefcase, etc.
You can also interact with Collect data through its content providers (see FormsProvider and InstanceProvider) and external apps can directly access Collect data in /sdcard/odk/.
