Android 在大查询的表中插入数据时发生IO异常

我试图在一个大查询的表中插入数据

   HttpTransport TRANSPORT = new NetHttpTransport();
    JsonFactory JSON_FACTORY = new JacksonFactory();
    List<String> SCOPES = Arrays
            .asList(BigqueryScopes.BIGQUERY);

    GoogleCredential credential = null;
    AssetManager am = this.getAssets();
    InputStream inputStream = null;
    try {
        inputStream = am.open("hbhjb-8f79f6642470.p12");
    } catch (IOException e2) {
        e2.printStackTrace();
    }


    File file = createFileFromInputStream(inputStream, this);


    try {
        credential = new GoogleCredential.Builder().setTransport(TRANSPORT)
                .setJsonFactory(JSON_FACTORY)
                .setServiceAccountId("projectnum-*******************3ee3130770087ceab09a482173@developer.gserviceaccount.com")
                .setServiceAccountScopes(SCOPES)
                .setServiceAccountPrivateKeyFromP12File(file)
                .build();
    } catch (GeneralSecurityException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    Bigquery bigquery = new Bigquery.Builder(TRANSPORT, JSON_FACTORY, credential)
            .setApplicationName("BigQuery-Service-Accounts/0.1")
            .setHttpRequestInitializer(credential).build();

    TableRow data = new TableRow();
    data.set("callerNumber", "123456789");


   TableDataInsertAllRequest.Rows row = new TableDataInsertAllRequest.Rows();
    row.setInsertId(System.currentTimeMillis()+"");
    row.setJson(data);
    TableDataInsertAllRequest requests = new TableDataInsertAllRequest();
    requests.setRows(Arrays.asList(row));

    TableDataInsertAllResponse response = null;
    try {
        response = bigquery.tabledata().insertAll("projectNum", "Data", "CallersData", requests).execute();
        Log.d("big query response", response.toString());
    } catch (IOException e) {
        e.printStackTrace();
    }

    for (TableDataInsertAllResponse.InsertErrors err: response.getInsertErrors()) {
        for (ErrorProto ep: err.getErrors()) {
            Log.e("error",ep.getReason() + " : " + ep.getMessage() + " at " + ep.getLocation());
        }
    }
}

我正在努力解决过去两天的问题。如果这里有人成功实施了它，请帮助我找到问题

提前谢谢

下面是stacktrace

result = {java.io.IOException@830026649024} Method threw 'java.io.IOException'  exception.
 cause = {java.io.IOException@830026649024} "java.io.IOException"
 detailMessage = null
 stackState = null
 stackTrace = {java.lang.StackTraceElement[30]@830026473856} 
 suppressedExceptions = {java.util.Collections$EmptyList@830023143656}  size = 0

尝试在不同的线程或异步任务中使用相同的代码。如果您仍然面临任何问题，请告诉我。

异常情况说明了什么？@Pentium10我添加了堆栈跟踪..谢谢。代码在我看来没问题。我甚至将它复制并粘贴到我的IDE中（当然更改了项目id等），它工作得很好，即该行成功地流式传输到BigQuery。抱歉，我被难住了。@polleyg是否会因为错误的凭据而导致此错误。我的意思是我对我在此处输入的密钥有疑问。是否会导致此错误。？@polleyg我们是否必须在清单或其他任何地方执行任何spl操作。如果相同的代码在您的端工作，则一定是一个愚蠢的错误..：（我欠你我的命.：DAs bigquery执行网络请求时，需要不同的线程而不是主线程来进行连接。我们不能在主线程上进行网络请求。
