- Launch Android Studio.
File → Open→ navigate to the module folder (e.g.,2-firstdemo).- Wait for Gradle to sync (bottom status bar).
- Click Run (▶) or
Shift+F10to launch on the emulator.
Each module is a standalone Android project — open the module folder itself, not the root of this repo.
⚠️ Modules that require credential setup before building:
- 7a Firebase — needs
google-services.jsonfrom Firebase Console. See7-2-connectivity-firebase/README.md.- 7b Supabase — needs
SUPABASE_URLandSUPABASE_KEYinlocal.properties. See7-3-connectivity-supabase/README.md.- 7c Bluetooth — no credentials needed, but requires a physical Android device (emulator has no Bluetooth radio).
Gradle sync fails — check that your Android Studio and SDK are up to date (SDK Manager → SDK Tools).
Emulator won't start — ensure hardware acceleration is enabled in your BIOS / Hyper-V settings.
google-services.json missing (Firebase module) — see 7-2-connectivity-firebase/README.md for the full setup walkthrough. In short: create a Firebase project, register the app with package com.example.connectivity_firebase, download the file, and drop it in the 7-2-connectivity-firebase/ folder.
SUPABASE_URL/SUPABASE_KEY not set (Supabase module) — see 7-3-connectivity-supabase/README.md. Add both values to local.properties in the root of the repo.
