If you need functionality in the AWS services used by the Amplify Predictions category that isn't available, we provide an escape hatch so you can get a reference to that service. For example, to get a reference to `RekognitionClient`:

import escapeHatchWarning from "/src/fragments/lib/android-escape-hatch-warning.mdx";

<Fragments fragments={{android: escapeHatchWarning}} />

import kotlinJavaInterop from "/src/fragments/lib/android-kotlin-java-interop.mdx";

<BlockSwitcher>

<Block name="Java">

<Fragments fragments={{android: kotlinJavaInterop}} />

```java
// Obtain reference to the plugin
AWSPredictionsPlugin predictionsPlugin = (AWSPredictionsPlugin)
  Amplify.Predictions.getPlugin("awsPredictionsPlugin");
AWSPredictionsEscapeHatch escapeHatch = predictionsPlugin.getEscapeHatch();

// Send a new request to the Rekognition endpoint directly using the client
RekognitionClient client = escapeHatch.getRekognitionClient();
CreateCollectionRequest request = CreateCollectionRequest.Companion.invoke((requestBuilder) -> {
  requestBuilder.setCollectionId("<new-collection-id-here>");
  return Unit.INSTANCE;
});
client.createCollection(request, new Continuation<CreateCollectionResponse>() {
  @NonNull
  @Override
  public CoroutineContext getContext() {
    return GlobalScope.INSTANCE.getCoroutineContext();
  }

  @Override
  public void resumeWith(@NonNull Object resultOrException) {
    Log.i("MyAmplifyApp", resultOrException.toString());
  }
});
```

</Block>
<Block name="Kotlin">

```kotlin
// Obtain reference to the plugin
val plugin = Amplify.Predictions.getPlugin("awsPredictionsPlugin")
val escapeHatch = (plugin as AWSPredictionsPlugin).escapeHatch

// Send a new request to the Rekognition endpoint directly using the client
val client = escapeHatch.rekognitionClient
val request = CreateCollectionRequest {
  collectionId = "<new-collection-id-here>"
}
client.createCollection(request)
```

In addition to the Amazon Polly APIs, the `PollyClient` returned in the escape hatch provides a way to create a presigned URL for a text to speech request. An example of creating a presigned URL is below.

<BlockSwitcher>
<Block name="Java">

```java
// Obtain reference to the plugin
AWSPredictionsPlugin predictionsPlugin = (AWSPredictionsPlugin)
  Amplify.Predictions.getPlugin("awsPredictionsPlugin");
AWSPredictionsEscapeHatch escapeHatch = predictionsPlugin.getEscapeHatch();

// Create a presigned URL to convert text to speech using the client
AmazonPollyPresigningClient client = (AmazonPollyPresigningClient) escapeHatch.getPollyClient();
SynthesizeSpeechRequest request = SynthesizeSpeechRequest.Companion.invoke((requestBuilder) -> {
  requestBuilder.setLanguageCode(LanguageCode.EnUs.INSTANCE);
  requestBuilder.setText("I like to eat spaghetti");
  return Unit.INSTANCE;
});

// The presigned URL needs to be created on a worker thread
runOnUiThread(new Runnable() {
  @Override
  public void run() {
    URL url = client.getPresignedSynthesizeSpeechUrl(request);
  }
});
```

</Block>
<Block name="Kotlin">

```kotlin
// Obtain reference to the plugin
val plugin = Amplify.Predictions.getPlugin("awsPredictionsPlugin")
val escapeHatch = (plugin as AWSPredictionsPlugin).escapeHatch

// Create a presigned URL to convert text to speech using the client
val client = escapeHatch.pollyClient as AmazonPollyPresigningClient
val request = SynthesizeSpeechRequest {
  languageCode = LanguageCode.EnUs
  text = "I like to eat spaghetti"
}

// The presigned URL needs to be created on a worker thread
runOnUiThread {
  val url = client.getPresignedSynthesizeSpeechUrl(request)
}
```
