 Replace `${ACCESS_KEY}` with yours obtained from [Picovoice Console](https://console.picovoice.ai/). Finally, when done release the resources using `falcon.release()`.
 
+### Android
+
+To include the Falcon package in your Android project, ensure you have included `mavenCentral()` in your top-level `build.gradle` file and then add the following to your app's `build.gradle`:
+
+```groovy
+dependencies {
+    implementation 'ai.picovoice:falcon-android:${LATEST_VERSION}'
+}
+```
+
+Create an instance of the engine and perform speaker diarization on an audio file:
+
+```java
+import ai.picovoice.falcon.*;
+
+final String accessKey = "${ACCESS_KEY}"; // AccessKey obtained from Picovoice Console (https://console.picovoice.ai/)
+try {
+    Falcon falcon = new Falcon.Builder()

+        FalconSegment[] segments = falcon.processFile(audioFile.getAbsolutePath());
+
+} catch (FalconException ex) { }
+```
+
+Replace `${ACCESS_KEY}` with yours obtained from Picovoice Console, and `${AUDIO_FILE_PATH}` with the path to the audio file.
+
+Finally, when done make sure to explicitly release the resources:
+
+```java
+falcon.delete()
+```
