E2E Test for setOrientation command on Android

This repo aims at providing the minimum material to have an end-to-end test for the setOrientation command on Android:

• an android app that observe the user_rotation system settings and display a human readable version of it in a text view:
  • 0 -> "PORTRAIT"
  • 1 -> "LANDSCAPE_LEFT"
  • 2 -> "UPSIDE_DOWN"
  • 3 -> "LANDSCAPE_RIGHT"
• a maestro script test-set-orientation-flow.yaml that calls the setOrientation command for each supported orientation and that assert that its visible on screen.

I tried to use no extra libraries and good old java to keep the assembled debug APK as small as possible: ~8Kb on my mac.

Context: mobile-dev-inc/maestro#2121

• Assemble a debug APK: ./gradlew assembleDebug
• Install it: adb install ./app/build/outputs/apk/debug/app-debug.apk
• Run the maestro flow: ./maestro test ./test-set-orientation-flow.yaml
• Observe test passing:

 ║
 ║  > Flow: test-set-orientation-flow
 ║
 ║    ✅   Launch app "com.example.maestro.orientation"
 ║    ✅   Set orientation LANDSCAPE_LEFT
 ║    ✅   Assert that "LANDSCAPE_LEFT" is visible
 ║    ✅   Set orientation LANDSCAPE_RIGHT
 ║    ✅   Assert that "LANDSCAPE_RIGHT" is visible
 ║    ✅   Set orientation UPSIDE_DOWN
 ║    ✅   Assert that "UPSIDE_DOWN" is visible
 ║    ✅   Set orientation PORTRAIT
 ║    ✅   Assert that "PORTRAIT" is visible
 ║

Note: this requires a version of maestro with the setOrientation command. See mobile-dev-inc/maestro#2121
