Update android API from 34 to 35

Summary

This PR addresses updates of Android API from 34 to 35 and visual issues that occurred after updating the app to target Android API 35 (Android 15) and It implements the necessary edge-to-edge enforcement opt-out.

Changes Made

Fixed Edge-to-Edge Enforcement Issues

• Added android:windowOptOutEdgeToEdgeEnforcement="true" to Theme.GATBReferenceGuide
• This temporarily (until we update to android 16) opts out of the new edge-to-edge enforcement introduced in Android 15

Files Modified

• app/src/main/res/values/themes.xml

       <!-- edge-to-edge opt-out for API 35 -->
        <item name="android:windowOptOutEdgeToEdgeEnforcement">true</item>

• /app/build.gradle

Before:

android {
    compileSdk 34

    defaultConfig {
        applicationId "org.apphatchery.gatbreferenceguide"
        minSdk 24
        targetSdk 34
        versionCode 34
        versionName "1.13"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildFeatures {
        viewBinding true
    }

After:

android {
    compileSdk 35

    defaultConfig {
        applicationId "org.apphatchery.gatbreferenceguide"
        minSdk 24
        targetSdk 35
        versionCode 34
        versionName "1.13"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildFeatures {
        viewBinding true
    }

Testing

• Tested on Android 15 (API 35) devices/emulator
• Confirmed no layout issues with edge-to-edge enforcement opt-out

Future Considerations

Important: The windowOptOutEdgeToEdgeEnforcement attribute has been removed in Android 16. We have priotized other work (updating UI for TB Guide Android) then later on will update the app to the latest Android 16 and fix layout issues that will follow.
