Question

嘿我正在尝试将Google Cloud Speech API用于Android，但我收到此错误并且无法绕过它。

java.lang.VerifyError: Verifier rejected class com.google.cloud.speech.v1
  .StreamingRecognizeResponse due to bad method java.lang.Object com.google
  .cloud.speech.v1.StreamingRecognizeResponse.dynamicMethod(com.google.protobuf
  .GeneratedMessageLite$MethodToInvoke, java.lang.Object, java.lang.Object) 
  (declaration of 'com.google.cloud.speech.v1.StreamingRecognizeResponse' 
  appears in /data/app/com.curieo.podcast-1/base.apk:classes65.dex)

  at com.google.cloud.speech.v1.StreamingRecognizeResponse.getDefaultInstance(StreamingRecognizeResponse.java:1095)
  at com.google.cloud.speech.v1.SpeechGrpc.<clinit>(SpeechGrpc.java:67)
  at com.curieo.podcast.ui.fragment.dates.googlecloud.StreamingRecognizeClient.<init>(StreamingRecognizeClient.java:57)

  at com.curieo.podcast.ui.fragment.dates.RecordFragment$1.run(RecordFragment.java:112)

我搜索了这个，但找不到解决方案。这是发生错误的代码

private Thread runner = new Thread() {

    public void run() {

        try {
            MicrophoneStreamRecognizeClient client;
            synchronized (this) {
                try {
                    client = new MicrophoneStreamRecognizeClient(getResources().openRawResource(R.raw.credential), Self); //crashes here 
                    client.start();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
};

以下是MicrophoneStreamRecognizeClient类的代码段：

public class MicrophoneStreamRecognizeClient {

private String host = "speech.googleapis.com";
private Integer port = 443;
private ManagedChannel channel;
private StreamingRecognizeClient client;

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

/**
 *
 * @param authorizationFile
 * @param host
 * @param port
 * @return
 * @throws IOException
 */
 private ManagedChannel createChannel(InputStream authorizationFile, String host, int port) throws IOException {

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

/**
 *
 * @param autorizationFile
 * @throws IOException
 */
 public MicrophoneStreamRecognizeClient(InputStream autorizationFile, IResults screen) throws IOException {

    channel = createChannel(autorizationFile, host, port);
    client = new StreamingRecognizeClient(channel, screen);
}

/**
 *
 * @throws IOException
 * @throws InterruptedException
 */
 public void start() throws IOException, InterruptedException {

    client.recognize();
}

/**
 *
 * @throws InterruptedException
 */
 public void stop() throws InterruptedException {

    client.shutdown();
}

}

Answer 1

清理build文件夹解决了问题。不确定为什么ART有问题，但Dalvik没有。

运行gradle清理任务并未完全清除我的构建文件夹。我必须手动完成，但干净可能适用于某些人。

Reference

java.lang.VerifyError可能由于某种原因发生：

一个类尝试扩展声明为final
方法尝试覆盖声明为final

将错误的参数传递给方法

 clint = new MicrophoneStreamRecognizeClient(getResources()
         .openRawResource(R.raw.credential), Self); //crashes here

我不知道Self是什么。那可以吗？

试试这个。

  synchronized (this) {
     MicrophoneStreamRecognizeClient client;
     try {
        client = new MicrophoneStreamRecognizeClient(getResources().openRawResource(R.raw.credential), Self); //crashes here 
         client.start();
     } catch (InterruptedException e) {
         e.printStackTrace();
     } catch (IOException e) {
         e.printStackTrace();
     }
 }

因为另一个问题可以!! try / catch块内的同步块!! java.lang.VerifyError reference

如果由library differences between runtime and compiling触发了java.lang.VerifyError，正如@Enamul所建议的那样，那么您可能需要检查com.google.cloud.speech.v1.StreamingRecognizeResponse和com.google.cloud.speech.v1beta1.StreamingRecognizeResponse之间的差异。

即便如此，请尝试使用该版本的beta版本。启发您的示例使用测试版。

java.lang.VerifyError：由于方法不正确，Verifier拒绝了类StreamingRecognizeResponse
