For some functionalities with Linestring-M-geometries implemented in the current version, the plugin uses a sqlite3-connection with spatialite-extension (used SpatiaLite-Functions: ST_TrajectoryInterpolatePoint, ST_IsValidTrajectory, ST_AddMeasure, ST_Locate_Between_Measures). A macOS-user reported th...

While there’s certainly room for additional functions, this is a great start and facilitates working with SpatiaLite databases considerably. Possible enhancements could be: Looking for a complete list of functions supported by SpatiaLite 2.3.1? Here it is:SpatiaLite 2.3.1 – SQL functions referen...
Is there a list of all supported Spatialite functions? Yes -http://www.gaia-gis.it/gaia-sins/spatialite-sql-4.4.0.html Does it use JDBC? No. It uses cursors - the suggested lightweight approach to access SQL used in the Android platform instead of the heavier JDBC. ...
