Android uses Gaud API to realize trajectory tracking (homework should be written by itself).

When the interval is 10 second and the distance moves more than 1 m at the same time, record the position information once and draw the action track for 60 seconds on the map.

See my last blog: /p/4b773727e42c for the quotation of God API.

The last blog has shown the map, so the functions that need to be realized are as follows:

1. Recording location

2. Draw a track on the map

Declare service components in the application tag of AndroidManifest.xml, and each app has its own independent location service. The statement is as follows:

Mainly positioning+callback function to draw the route.

(You don't need to add it here, but you may get an error but still run or flash back. )

I don't know if it's not positioned correctly. A short walk shows that the gap is a bit big. It is also possible that there will be a deviation between the first positioning and the second positioning, resulting in the inaccuracy of the first line segment.

Long distance trajectory tracking is more accurate.
