android gps 代码 分析(4)

android

if (pendingCallbacks & kStatus) {

env->CallVoidMethod(obj, method_reportStatus, sGpsStatusCopy.status); }

if (pendingCallbacks & kSvStatus) {

env->CallVoidMethod(obj, method_reportSvStatus);

}

if (pendingCallbacks & kXtraDownloadRequest) {

env->CallVoidMethod(obj, method_xtraDownloadRequest);

}

if (pendingCallbacks & kDisableRequest) {

// don't need to do anything - we are just poking so wait_for_event will return. }

}

//hardware 那部分有个线程gps_state_thread 一直在读串口的内容并进行解析，最后解析到location的信息 由cpp文件的GpsCallbacks sGpsCallbacks = { location_callback....}同步上层的线程

gps_state_thread

----->nmea_reader_addc

----->nmea_reader_parse

------> location_callback

------->数据上报
