App Dev Worksheet: Permissions and Versions

App development lesson 23: Privacy, permissions and publishing · Set 106 · 40 questions

Developer's tip (Need it? Number it.): Ask only for permissions the app’s main job needs, and say why. Version = major.minor.patch. Bug fix → patch + 1; new feature → minor + 1, patch 0; big change → major + 1, others 0. Compare major, then minor, then patch as numbers: 10 is bigger than 9.
