Question

我开发了一款适用于黑莓的应用程序，它已经从appworld中获得批准，但却出现以下错误

on 4.6

Critical tunnel failure

和

on 5.0 and 6.0
ava.io APN not specified

请帮助解决为什么会出现此错误以及如何解决此问题

Answer 1

我认为问题是你没有为网址添加适当的连接后缀。

按照链接可以解决您的问题：http：//www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800451/800563/What_Is_-_Different_ways_to_make_an_HTTP_or_socket_connection.html？nodeid = 826935＆amp; vernum = 0

您还可以使用以下示例代码：

private static String getConnectionString(){
    String connectionString="";
    if(WLANInfo.getWLANState()==WLANInfo.WLAN_STATE_CONNECTED){
        connectionString=";interface=wifi";
    }

     else if((CoverageInfo.getCoverageStatus() & CoverageInfo.COVERAGE_MDS) == CoverageInfo.COVERAGE_MDS){
         connectionString = ";deviceside=false";
    }
        else if((CoverageInfo.getCoverageStatus() & CoverageInfo.COVERAGE_DIRECT)==CoverageInfo.COVERAGE_DIRECT){
            String carrierUid=getCarrierBIBSUid();
            if(carrierUid == null) {
                connectionString = ";deviceside=true";
            }
            else{
                 connectionString = ";deviceside=false;connectionUID="+carrierUid + ";ConnectionType=mds-public";
                }               
            }
     else if(CoverageInfo.getCoverageStatus() == CoverageInfo.COVERAGE_NONE)
        {

        }
    return connectionString;
    }

Answer 2

只是为了解决一些问题。

@Jisson你的回答很有帮助

但是你没有包含方法getCarrierBIBSUid（）

的代码

/**
 * Looks through the phone's service book for a carrier provided BIBS network
 * @return The uid used to connect to that network.
 */
private static String getCarrierBIBSUid()
{

    ServiceRecord[] records = ServiceBook.getSB().getRecords();
    int currentRecord;

    for(currentRecord = 0; currentRecord < records.length; currentRecord++)
    {
        if(records[currentRecord].getCid().toLowerCase().equals("ippp"))
        {
            if(records[currentRecord].getName().toLowerCase().indexOf("bibs") >= 0)
            {
                return records[currentRecord].getUid();
            }
        }
    }

    return null;
}

包含

也许会有所帮助

    if (DeviceInfo.isSimulator()){
        return   ";deviceSide=true";    
    }

在getConnectionString（）方法的开头有关详细信息，请参阅Melick's Blog

Answer 3

通过在手机上设置 APN 值并使用其他答案中建议的连接字符串代码解决了此问题。

更改您的APN设置（在南非）

On Home screen, click Options
Click Advanced Options and then TCP
Enter the APN: **internet** 
   username: **guest**
   password: **guest**
Press the Menu key and select Save
