5 years ago 92行写的是 //监听gps状态 locationManager.addGpsStatusListener(listener);没想明白为什么会空指针

5 years ago 这个要看你的MainWorkService:162这一行是咋写的 at hxht.megaeyes.service.MainWorkService.sendLocation(MainWorkService.java:162)

5 years ago 162： sendLocation();//发送实时定位数据
private void sendLocation(){
LocationUtils locationUtils = LocationUtils.getInstance(getApplicationContext());
Location location=locationUtils.showLocation();
if(location!=null){
ServiceRequest request = new ServiceRequest(MainWorkService.this, null, new IResponseCallBack
@Override
public void executeResponsedAction(Void dataObject, Boolean isSuccess, String responseMessage) {
if(isSuccess){
LogToFileUtils.write("定位数据上报成功");
}else{
//弹出相应对话框和对应处理
LogToFileUtils.write(responseMessage);
}
}
@Override
public void executeResponsedActionForLogin(String dataObject, Boolean isSuccess, String responseMessage) {
}
@Override
public void onFailure(HttpException e, Response<String> response) {
LogToFileUtils.write("onFailure:"+e.getMessage());
}
});
String idCard= (String) SPUtils.get(Constants.USERDATA,this,Constants.IDCARD,"");
if(UrlConstant.isDebug){
idCard=UrlConstant.ID_CARD;
}
String url = URLManager.createGpsUpUrl(UrlConstant.LOCATION_IP,UrlConstant.LOCATION_PORT,idCard,location.getLatitude()+"",location.getLongitude()+"");
LogToFileUtils.write("url="+url);
try {
request.performanceURLQueryNoneData(url);
} catch (Exception ex) {
LogToFileUtils.write( ex.getMessage());
}
}
}public static LocationUtils getInstance(Context context) { if (uniqueInstance == null) { synchronized (LocationUtils.class) { if (uniqueInstance == null) { uniqueInstance = new LocationUtils( context ); } } } return uniqueInstance; }
请指教，谢谢

5 years ago 静态、单例在不同进程中会失效，这可能会导致空指针。请再确认下MainWorkService的进程和LocationUtils 初始化时的进程，是不是同一个进程。

5 years ago 是在主进程的， Caused by: java.lang.NullPointerException: Attempt to read from field 'android.os.MessageQueue android.os.Looper.mQueue' on a null object reference主要是这个错误第一次遇到
