我正在尝试使用Google的语音来为Android发送文本API。在SpeechClient中设置凭据时出现错误

Question

我想在android中使用凭据实例化SpeechClient对象。稍后将其用于将音频输入转换为文本。

我的代码如下：

val speechSettings = SpeechSettings.newBuilder()
            .setCredentialsProvider(
                FixedCredentialsProvider.create(
                    GoogleCredentials.fromStream(
                        context.resources.openRawResource(R.raw.my_key_name)
                    )
                )
            )
            .build()

val speechClient = SpeechClient.create(speechSettings)

在gradle中，我添加了以下内容：

implementation 'com.google.cloud:google-cloud-speech:0.80.0-beta'
implementation "io.grpc:grpc-okhttp:1.4.0"

运行应用程序时出现以下错误：

java.lang.AbstractMethodError: abstract method "java.util.concurrent.ScheduledExecutorService io.grpc.internal.ClientTransportFactory.getScheduledExecutorService()"

完整堆栈跟踪：
