DataWedge

For example, Profile A is unassociated and Profile B is associated with activity B. If activity A is launched and
uses
SwitchToProfile function to switch to Profile A, then Profile A will be active whenever activity A is in the
foreground. When activity B comes to the foreground, DataWedge will automatically switch to Profile B.
When activity A returns to the foreground, the app must use
SwitchToProfile again to switch back to Profile
A. This would be done in the
onResume method of activity A.
NOTE: Use of this API changes only the runtime status of the scanner; it does not make persistent changes to the Profile.
Notes
Because DataWedge will automatically switch Profile when the activity is paused, Zebra recommends that this
API function be called from the onResume method of the activity.
After switching to a Profile, this unassociated Profile does not get assigned to the application/activity and is
available to be used in the future with a different app/activity.
For backward compatibility, DataWedge’s automatic Profile switching is not affected by the above API
commands. This why the commands work only with unassociated Profiles and apps.
DataWedge auto Profile switching works as follows:
Every second…
• Sets newProfileId to the associated Profile ID of the current foreground activity.
• If no associated Profile is found, sets newProfileId to the associated Profile ID of the current foreground
app.
• If no associated Profile is found, sets newProfileId to the current default Profile (which MAY NOT be
Profile0).
• Checks the newProfileId against the currentProfileId. If they are different:
• deactivates current Profile
• activates new Profile (newProfileId)
• sets currentProfileId = newProfileId
