Question

当我使用google v1语音库在Android Studio中构建测试语音应用时，它可以正常运行。使用v1p1beta1语音库，当它访问json凭证文件和旧式通用编解码器并生成以下错误时，就会发生运行时错误：

java.lang.NoSuchMethodError：没有静态方法encodeBase64（Ljava / lang / String;）[B Lorg / apache / commons / codec / binary / Base64;中的B或其上级类（“ org.apache.commons.codec.binary.Base64”的声明出现在/system/framework/org.apache.http.legacy.boot.jar中）

如何使v1p1beta1语音库不使用旧版公共图书馆版本？

以下是gradle文件，其中引用了最新的v1p1beta1语音和grpc库：

这是堆栈跟踪错误输出：

该版本的库似乎存在问题。 Here是@ajaaym的解决方法：

从依赖项中删除：

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();
    }

我建议使用可用的latest库
