There was a problem hiding this comment.
Wouldn't it be better to set the explicit GMS NEVER_EXPIRE value if this is Long.MAX_VALUE?
if (this == org.owntracks.android.location.geofencing.Geofence.NEVER_EXPIRE)
com.google.android.gms.location.Geofence.NEVER_EXPIRE // -1L, GMS sentinel
else

GMS geofence registration silently fails with ApiException: 10 on devices with significant uptime. GMS internally computes elapsedRealtime() + expirationDuration to derive an absolute expiration time. When expirationDuration is Long.MAX_VALUE (the NEVER_EXPIRE constant), this addition overflows the signed long, producing a negative value that GMS rejects as invalid. The failure was silent because neither success nor failure was logged.
Fix:
