Need to have QGIS open with all my settings/layers/projections etc by default. Created a .qgs file that has all this info in it. Using Android and Ubuntu. Tried a shortcut to the .qgs file in android and that didn't work.
The QGIS guide says:
Command line option ---project
Starting QGIS with an existing project file is also possible. Just add the command line option ---project followed by your project name and QGIS will open with all layers loaded described in the given file.
I guess they meant --project.
Does that solve your problem?
