chore: update LaunchDarkly Android client SDK to 5.14.0 and appcompat to 1.8.0

[devin-ai-integration]

Summary

Keeps the example on the latest dependency versions within their current majors:

-implementation 'com.launchdarkly:launchdarkly-android-client-sdk:5.13.3'
+implementation 'com.launchdarkly:launchdarkly-android-client-sdk:5.14.0'
-implementation 'androidx.appcompat:appcompat:1.7.1'
+implementation 'androidx.appcompat:appcompat:1.8.0'

Latest-version evidence:

• launchdarkly-android-client-sdk latest on Maven Central is 5.14.0 (released 2026-08-12; adds per-hook evaluation exposure deduplication) — the repo pinned 5.13.3.
• androidx.appcompat:appcompat latest stable is 1.8.0 — the repo pinned 1.7.1.
• androidx.core:core-ktx (1.19.0) and AGP (9.3.1) are already latest stable; Gradle wrapper left at 9.6.1 since nothing requires 9.7.0.

No example code changes were needed — no deprecated LaunchDarkly APIs are used (LDConfig.Builder(AutoEnvAttributes), LDClient.init, boolVariation, registerFeatureFlagListener are all current), and ./gradlew assembleDebug --warning-mode all reports no Gradle/AGP/Kotlin deprecation warnings.

How to test it

Built and ran end-to-end on a local Android 34 x86_64 emulator (Android SDK 37, JDK 17, Gradle 9.6.1) with the hello-apps mobile key and flag key supplied via untracked local edits (never committed):

./gradlew assembleDebug          # BUILD SUCCESSFUL
adb install -r app/build/outputs/apk/debug/app-debug.apk
adb shell am start -n com.launchdarkly.hello_android/.MainActivity
adb exec-out uiautomator dump /dev/tty | grep 'feature flag evaluates to'
# -> feature flag evaluates to true

Limitations

• Emulator run used a locally configured mobile key/flag key; repo CI (run.yml) performs the same check with the keys from SSM.
