I am looking for a android compass app who can be used with the external.app feature of odk collect.
My use case :
In my xlsform, i have a list (select_one) of point destination (for fill the form about this selected point). For each point, i have the lat/lon in the choice sheet (i get this values with the 'instance' function). So, when i select a point, i got the lat lon in a note question.
Actually, the user need to copy the lat lon in a paper for paste it in a compass app for walk to the point (actualy gps compass navigator was used, or waypoint finder).
My question is : can i propose to open an android compass app directly from odk with the lat lon comming from the 'intent' message ?
Another similar question : how can i see if app can be call with intent message ? Only by unzip the jar of this app ?
Thank you !
