GPS定位没有发生的第一次。在通知栏无状态 [英] GPS fix Is not happening for the first time. No status in notification bar
问题描述
创建一个地点报警基于应用程序。一切都是仿真器工作正常。但在实际的设备会出现以下错误。
情景:
开机状态的GPS。
打开我的应用程序在手机上。
在状态栏上没有GPS的象征。
应用获得力量关闭。
要解决这种情况下,我做以下的事情
像打开地图,GPS必备的应用程序。
我的GPS值的搞定了。
开场之后我的应用程序。
应用程序正常工作。
提供了必要的codeS如下:
在我的onCreate方法
fixlocation = orgManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
@覆盖
保护无效onResume(){
super.onResume();
orgManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,0,1000,这一点);
orgManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,0,1000,这一点);
mo.enableCompass();
mo.enableMyLocation();
}/ **停止更新活动时暂停* /
@覆盖
保护无效的onPause(){
super.onPause();
orgManager.removeUpdates(本);
mo.disableCompass();
mo.disableMyLocation();
}@覆盖
公共无效onLocationChanged(地点){
// TODO自动生成方法存根 //orgManager.removeUpdates(this); 如果(位置!= NULL){
currLatitude = location.getLatitude();
currLongtitude = location.getLongitude();
}}
什么我现在需要做的?
的LocationManager LM =(的LocationManager)getSystemService(Context.LOCATION_SERVICE);
地点= lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);currLat = location.getLatitude();
currentLang = location.getLongitude();
试试这个来获得当前位置。
onLocationChanged只会打电话的时候,你的设备改变位置,但
第一次应用程序启动时,您可以使用此code。
Created a Location alarm based app. Everything is working fine on emulator. But the following error occurs in real device.
Scenario:
Turned on GPS. Opened my app in phone. No GPS symbol in status bar. App getting force closed.
To fix this scenario, I am doing the following thing
Open any application like Maps, GPS Essentials. My GPS values is getting fixed. Opening my application after that. App working fine.
Providing the necessary codes below:
in my Oncreate method
fixlocation = orgManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
@Override
protected void onResume() {
super.onResume();
orgManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 1000, this);
orgManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 1000, this);
mo.enableCompass();
mo.enableMyLocation();
}
/** Stop the updates when Activity is paused */
@Override
protected void onPause() {
super.onPause();
orgManager.removeUpdates(this);
mo.disableCompass();
mo.disableMyLocation();
}
@Override
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
//orgManager.removeUpdates(this);
if (location != null) {
currLatitude = location.getLatitude();
currLongtitude = location.getLongitude();
}}
What do I need to do now?
LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Location location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
currLat = location.getLatitude();
currentLang = location.getLongitude();
Try this to get current location.
onLocationChanged will call only when location of your device changes but
first time when your application starts you can use this code.
