Android GIS Development Series--Introductory season (Gdal) simply write a shp file

Gdal is used to read and write raster and vector data, in the Gdal official website, you can download the relevant resources for the compilation of the platform. In fact, the bottom of ArcGIS is also used gdal to read SHP files, that in Android can directly read and write shp files, is OK. Someone here has compiled the android-side so. You can also try compiling the related so yourself.

Create a new project, import the downloaded so and related resources, the relevant directory structure is as follows:

Note that the associated package name for Gdal should not be modified, so that so does not read the corresponding class.
Simply write a SHP, note the Guide package, to import Org.gdal the following related classes:
