Location Type Reference

On a successful location request, the location callback returns a response code that indicates the source of the location fix. Use the following table to interpret the response code.

Response Code	Description	Details
0	Location failed	Call AMapLocation.getErrorCode() to retrieve the error code, then refer to the Error Code Reference for troubleshooting.
1	GPS location	Location result from the device's GPS module. High accuracy, typically within 10–100 meters.
2	Previous location	Returned when a network location request completes in under 1 second, or when the device's position changes very little between two location requests. Movement is detected by the device's sensors.
4	Cached location	A previously cached network location result from the same device position, returned from a short time ago.
5	Wi-Fi location	A network-based location using Wi-Fi. Generally more accurate than cell tower positioning, with accuracy typically between 5–200 meters.
6	Cell tower location	A network-based location relying solely on mobile network signals (e.g., from China Mobile, China Unicom, or China Telecom). Accuracy is typically between 500–5000 meters.
8	Offline location	-
9	Last known location	-
11	Approximate location	Returned when the user has set the app's location permission to "approximate location." Provides the user's general area.
12	System network location	Used when AMap's network location (Wi-Fi location) fails. Supported in SDK version 6.4.5 and later.
