"Received EOS on DATA" frame after around 1 minute running

I setup a demo of the Google Cloud Speech API running on Android with AudioRecord to retrieve audio from the microphone. Its working but after a while (+/- 1 minute) the channel closes by itself. I basically used the java StreamRecognizeClient example, including the last changes to the gRPC 1.0 and the ManagedChannelBuilder There is a definition to set a timeout or am I doing something wrong here?

Here is the main code setup:

Setup channel

private static final List<String> OAUTH2_SCOPES = Arrays.asList("https://www.googleapis.com/auth/cloud-platform");

    public static ManagedChannel createChannel(InputStream authorizationFile, String host, int port) throws IOException {

        GoogleCredentials creds = GoogleCredentials.fromStream(authorizationFile);
        creds = creds.createScoped(OAUTH2_SCOPES);
        ManagedChannel channel =
                ManagedChannelBuilder.forAddress(host, port)
                        .intercept(new ClientAuthInterceptor(creds, Executors.newSingleThreadExecutor()))
                        .build();

        return channel;
    }

Recognize setup and loop

public void recognize() throws InterruptedException, IOException {

        try {
            // Build and send a StreamingRecognizeRequest containing the parameters for
            // processing the audio.
            RecognitionConfig config =
                    RecognitionConfig.newBuilder()
                            .setEncoding(RecognitionConfig.AudioEncoding.LINEAR16)
                            .setSampleRate(this.RECORDER_SAMPLERATE)
                            //.setLanguageCode("en-US")
                            .build();

            // Sreaming config
            StreamingRecognitionConfig streamingConfig =
                    StreamingRecognitionConfig.newBuilder()
                            .setConfig(config)
                            .setInterimResults(true)
                            .setSingleUtterance(false)
                            .build();
            // First request
            StreamingRecognizeRequest initial =
                    StreamingRecognizeRequest.newBuilder().setStreamingConfig(streamingConfig).build();

            requestObserver.onNext(initial);

            // Microphone listener and recorder
            recorder = new AudioRecord(MediaRecorder.AudioSource.MIC,
                    this.RECORDER_SAMPLERATE,
                    this.RECORDER_CHANNELS,
                    this.RECORDER_AUDIO_ENCODING,
                    bufferSize);

            recorder.startRecording();

            byte[] buffer = new byte[bufferSize];
            int recordState;

            // loop through the audio samplings
            while ( (recordState = recorder.read(buffer, 0, buffer.length) ) > -1 ) {

                // skip if there is no data
                if( recordState < 0 )
                    continue;

                // create a new recognition request
                StreamingRecognizeRequest request =
                        StreamingRecognizeRequest.newBuilder()
                                .setAudioContent(ByteString.copyFrom(buffer, 0, buffer.length))
                                .build();

                // put it on the works
                requestObserver.onNext(request);
            }

        } catch (RuntimeException e) {
            // Cancel RPC.
            requestObserver.onError(e);
            throw e;
        }
        // Mark the end of requests.
        requestObserver.onCompleted();
    }

Need some help here, because I’m not figuring it out!

Thanks

@ricmalta Can you please take a look at https://github.com/GoogleCloudPlatform/android-docs-samples/tree/master/speech/Speech
