You can open KML files on your Android device directly in TPE. TPE will examine the file for any Placemarks and will import those into your locations list within the app.
Duplicates are detected and are not imported.
For example, you can email yourself a KML file, or send it via a chat client and then download it. When prompted, choose "Open in TPE (import)":
There is also an option to import from your SD card or internal storage from within TPE itself. However, we recommend open the KML file as described above instead - the older method of importing from within TPE will be removed in a future release.
