严重隧道故障错误黑莓



我为黑莓开发了一个应用程序,它得到了应用程序世界的批准,但它给出了以下错误

on 4.6
Critical tunnel failure 

on 5.0 and 6.0
ava.io APN not specified  

请帮助为什么会出现此错误以及如何解决它

我认为问题是您没有向 url 添加适当的连接后缀。

并且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;
    }

只是为了澄清一些问题。

@Jisson你的回答很有帮助

但是您没有包含方法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;
}

此外,包括以下内容可能会有所帮助

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

在 getConnectionString() 方法的开头有关更多信息,请参阅 Melick 的博客

通过自行设置手机上的 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
