At novoda we are living and breathing Android. That's why we were very excited to see Steve Pomeroy comprehensive take on the Android lifecycle diagrams.
But some small details set me off personally - I guess I have OCD to some degree - and so I tweaked the version a bit before we printed it out for the office wall. Since I applied the changes to the SVG instead of the dia-file I deleted this file to not cause any confusion. The PDF and the PNG are exported from Inkscape.

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.
If you see any discrepancies or errors in this diagram, please submit a pull request or contact [email protected].
Vector versions suitable for printing: PDF or SVG
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.
