Same test code
Run identical suites per API image; only the environment changes.

Test Android apps on different OS versions
Behaviour and policy shift every API level—permissions, background work, notifications, file access. Validate your supported range with the same scenarios on each version, using Android OS testing practices, compatibility checks, and device simulation where physical labs are thin.
Version matrix tips
- Always cover minSdk and targetSdk; add versions where Play or OEM share shows real traffic.
- Re-run permission and storage flows after bumping targetSdk—regressions cluster there.
- Pair version tests with one low-RAM profile to catch performance cliffs.
Execution pattern
Version deltas
Time-box passes focused on behaviour changed in release notes for that API band.
Tagged runs
Store build ID + profile so failures are auditable.
How Device Changer fits
Spin consistent targets per OS band for regression and exploratory work without re-imaging devices by hand.

FAQ
Do I need every intermediate Android version?
Not usually—pick endpoints and one midpoint unless analytics show a spike on a specific version.
What about Google Play pre-launch reports?
Use them as signal, not the whole strategy; complement with owned suites on your critical paths.
