I would like to store the datasets on the sd card. This way i will be able to change them without having to reinstall the application. The question is, how can i reach the sd card from the native code? As i understand this is how the dataset loads from the assets folder: dataSetStonesAndChips->load(s, QCAR::DataSet::STORAGE_APPRESOURCE). The problem is that the assets folder is read-only during runtime, so i cannot change the datasets there, that's why i have to use the sd card.
