Update Android/WPF Demo and Portrait Processing to SDK 1.0.0 Beta.2

[der3318]

Recently we released a newer package of Azure SDK for face service:

Language	SDK	Pull Request	Version Change
C#	Azure.AI.Vision.Face	Azure/azure-sdk-for-net#45402	1.0.0-beta.1 ➡️ 1.0.0-beta.2
Python	azure.ai.vision.face	Azure/azure-sdk-for-python#37044	1.0.0b1 ➡️ 1.0.0b2
Java	com.azure:azure-ai-vision-face	Azure/azure-sdk-for-java#41823 Azure/azure-sdk-for-java#42239	1.0.0-beta.1 ➡️ 1.0.0-beta.2

Bump the lib versions and address the breaking changes (e.g., enum rename) for AndroidDetect, DemoWPF, and PortraitProcessing samples.

Using AGP 8.0.0 results in the following error:

Execution failed for task ':app:mergeExtDexDebug'.
java.lang.NullPointerException: Cannot invoke "String.length()" because "<parameter1>" is null

With the build environment:

• Android Studio | Ladybug (2024.2.1) | September 2024
• JDK 21, which is the new default JetBrains Runtime (JBR) that comes with Android Studio 2024.2.1 (see blog)
• Gradle 8.5, the minimum version that supports Java 21 (see compatibility matrix)

---

Upgrading AGP from 8.0.0 to 8.3.2, which is the maximum version compatible with Gradle 8.5 (see compatibility table and 8.3.* release notes), solves the problem.

Accordingly, the API level is suggested to migrate from 33 to 34:

The maximum API level that Android Gradle plugin 8.3 supports is API level 34.

android {
    namespace 'com.contoso.facetutorial'
-   compileSdk 33
+   compileSdk 34
    defaultConfig {
        minSdkVersion 28
-       targetSdkVersion 33
+       targetSdkVersion 34
        versionCode 1
        versionName "1.4.3"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
