Complete Android Fragment & Activity Lifecycle
After struggling with trying to figure out how various pieces fit together, I’ve done some research and put together the complete Android Activity/Fragment lifecycle chart. This has two parallel lifecycles (activities and fragments) which are organized vertically by time. Lifecycle stages will occur in the vertical order in which they’re displayed, across activities and fragments. In this way, you can see how your fragments interact with your activities.
Vector versions suitable for printing: [PDF][] or [SVG][]
Some Notes
This intentionally leaves off user-triggered callbacks (such as
onOptionsItemSelected()), focusing on the lifecycle stages that are triggered
by the system, in order to keep the diagram more focused on the parts that are
hard to follow.
The canonical format of the diagram is the [Dia][] file. It was then exported to SVG, hand-tweaked to fix font sizes, and imported into [Inkscape][] to do an SVG, PDF, and PNG render. I hope to find a better workflow for this going forward; patches always welcome.
