Testing and Play Store release

Test your app and publish it on Google Play.

📖 Key ideas

Unit tests (JUnit) and UI tests (Compose testing, Espresso).
Build a signed Android App Bundle (AAB).
Use Play App Signing; keep your upload key safe.
Create a Play Console listing: icon, screenshots, privacy policy, data safety form.
Release in stages: internal testing, closed testing, then production.

💡 Real-life example: Release tracks are rehearsals: friends first, then a bigger audience, then the full show.
