程序启动黑屏定位

【程序启动异常】
耗时30分钟
搜狐海外版本增加国家、币种配置。在该管理对象初始化时，需要通过android读取国家代码
DiamondPriceMgr::DiamondPriceMgr()
{
#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
    const char * countryCode = ClientInterfaceAndroid::getCountryIso();
#else
    const char * countryCode = "ID"; 
#endif
    m_priceInfo = getPriceInfoByCountryCode(countryCode); 


#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
    const char * appSecret = CommData::shared()->getTitleValue("CyPayAppSecret");
    CLDMessageBox(appSecret, "");
    ClientInterfaceAndroid::setPaySetting(m_priceInfo->country, m_priceInfo->currency, appSecret);
#endif
}
添加代码后，程序启动黑屏

反复核对修改Jni转换函数，没有找到问题原因。不过可以排查Java代码的问题
后面仔细分析日志文件，发现一个疑点，这个错误是在加载so动态库时触发的。

联想到一个可能，刚加载so库时，jni功能还没准备好，才会出现空指针（0x00000000）
而代码中确实是把对象放到堆上了，需要错开
static DiamondPriceMgr sDiamondPriceMgr; 
DiamondPriceMgr * DiamondPriceMgr::shared()
{
    return &sDiamondPriceMgr;
}
将上面加载时初始化代码，修改为下面使用时才初始化的代码
DiamondPriceMgr * DiamondPriceMgr::shared()
{
    static DiamondPriceMgr * sDiamondPriceMgr = NULL;
    if (!sDiamondPriceMgr)
    {
    sDiamondPriceMgr = new DiamondPriceMgr();
    }
    return sDiamondPriceMgr;
}
测试正常。
这个错误说明，调用jni函数时要错开加载时的那段时间
