Android v1p1beta1 Speech - java.lang.NoSuchMethodError: No static method decodeBase64

Question

When I build test speech app with Android Studio using google v1 speech library it works fine. Using v1p1beta1 speech library, a run time error occurs when it accesses the json credentials file and legacy commons codec and generates the following error:

java.lang.NoSuchMethodError: No static method decodeBase64 (Ljava/lang/String;)[B in class Lorg/apache/commons/codec/binary/Base64; or its super classes (declaration of 'org.apache.commons.codec.binary.Base64' appears in /system/framework/org.apache.http.legacy.boot.jar)

How do I get v1p1beta1 speech library to not use the legacy commons library version?

Here is the gradle file with references to the latest v1p1beta1 speech and grpc libraries:

It seems that there was an issue with that version of the library. Here is a workaround by @ajaaym:

Remove from dependencies:

compile "com.google.api.grpc:grpc-google-cloud-speech-v1p1beta1:0.39.0"

Add the below code:

FixedCredentialsProvider fixedCredentialsProvider = FixedCredentialsProvider.create(GoogleCredentials.create(null));
    try(SpeechClient client = SpeechClient.create(SpeechSettings.newBuilder().setCredentialsProvider(fixedCredentialsProvider).build())) {
    } catch (IOException e) {
      e.printStackTrace();
    }

I would recommend using the latest library available
