Installing Error Of Shapely And Gdal On Pydroid

Pydroid is a good app for beginners and others for running python on android. I could install many useful libraries without any problems, but I don't understand why some libraries

Solution 1:

The three python module you mention all depend on C libraries, i.e. they are not pure python but provide an interface to lower level functions. Specifically, the three mentioned python modules need these libraries:

1. GDAL is toolset for the GDAL library
2. Shapely, as your error message suggests depends on Geos
3. pyproj is an interface for proj

As such, you would need to download and compile these libraries yourself for your system (or find pre-compiled binaries, but that sounds unlikely for your setup). Only then would you be able to install and use the corresponding python modules.
