invalid type:

Error message

invalid type: 

What it means

Guard in Geofence.checkType: the geofence type value is not a recognized constant, so the geofence cannot be interpreted. The offending value is appended; used both at construction and when reading types back via createFromParcel/typeToString.

Solutions

1. Use only the recognized geofence type / transition constants (ENTER, EXIT, DWELL)
2. Validate stored or received type values before building a Geofence
