+# Pet Clinic Android App
+
+A simple Android frontend for the [application-signals-demo](https://github.com/aws-observability/application-signals-demo) PetClinic application.
+
+## Requirements
+
+- Android Studio Hedgehog | 2023.1.1 or newer
+- Android SDK 34
+- Minimum SDK 24 (Android 7.0)
+
+## Building
+
+1. Open the project in Android Studio
+2. Sync the project with Gradle files
+3. Run the app on an emulator or physical device
+
+## Instrumentation with AWS OTEL Android
+
+### 1. Add Dependencies
+
+Add to your app's `build.gradle.kts`:
+
+```kotlin
+dependencies {
+    implementation("software.amazon.opentelemetry.android:agent:1.0.0")
+
+    // For HTTP instrumentation
+    byteBuddy("io.opentelemetry.android.instrumentation:okhttp3-agent:0.15.0-alpha")
+}
+```
+
+### 2. Create Configuration File
+
+Create `app/src/main/res/raw/aws_config.json`:
+
+```json
+{
+  "aws": {
+    "region": "us-east-1",
+    "rumAppMonitorId": "<your-app-monitor-id>"
+  },
+  "otelResourceAttributes": {
+    "service.name": "PetClinic-Android",
+    "service.version": "1.0.0",
+    "deployment.environment": "production"
+  }
+}
+```
+
+### 3. That's it!
+
+The agent automatically initializes and collects telemetry including:
+- Activity lifecycle events
+- Network requests
+- Crashes and ANRs
+- UI performance metrics
