Android v1p1beta1语音-java.lang.NoSuchMultiodError： No静态方法decdeBase64

Question

当我使用Android Studio使用google v1speech library构建测试语音应用程序时，效果很好。使用v1p1beta1speech library，当它访问json凭据文件和旧式commons编解码器并生成以下错误时，会发生运行时错误：

JAVAlang.NoSuchMethodError:没有静态方法decodeBase64（Ljava/lang/String；）[B类Lorg/apache/commons/codec/binary/Base64；或其超类（在/system/framework/org.apache.commons.codec.binary.Base64中出现'org.apache.codec.Base64'声明）

如何使v1p1beta1语音库不使用旧的通用库版本？

以下是gradle文件，其中引用了最新的v1p1beta1speech和grpc库：

那个版本的库似乎有问题。以下是@ajaaym的变通方法：

从依赖关系中删除：

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

添加以下代码：

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

我建议使用最新的可用库
