Get list of all Android apps with QPython / sl4a : Does anyone know how I can get a list of packages from all apps installed on Android using Qpython?

My goal is to list all apps and be able to run, using getLaunchableApplications () and the "launch" function until I could open some, but it does not work for everyone, I made tests and if I get the name of the packages I should be able to open any app with " startactivity ".

Thank you very much in advance
