无法获得当前GPS定位坐标 [英] Unable to get current GPS Location co-ordinates
问题描述
我一直在努力让我的当前位置的GPS坐标，但是我从来没有应用程序锁定到GPS卫星。
I have been trying hard to get my current location's GPS co-ordinates but my app never locks on to a GPS satellite.
在通知区域的图标GPS只是不断闪烁。
The GPS icon in the notification area just keeps on blinking.
虽然我尝试使用谷歌地图在Android（在pre-安装的应用程序），并且事情是能够在LOCKON约60秒！在两者的情况下，我的3G数据连接被上和工作切换。
Whereas I tried using Google Maps on Android (the pre-installed app) and that thing is able to lockon in approx 60 secs! In both of the cases my 3G data connection was switched on and working.
更新：我使用的是Android 2.3.3（的HTC Desire S（出厂安装的操作系统，没有更新应用））的logcat输出的此处。现在，这是没有设置 LocationUpdates（）的最小时间和更新之间的最小距离为0，0。
Update: I am using Android 2.3.3 (HTC Desire S (Factory installed OS; no updates applied)) Logcat output is here. Now this is without setting LocationUpdates()'s min time and min-distance between update to 0, 0.
更新＃2：我的前面code是这里（引擎收录链接）。
Update #2: My earlier code is here(PasteBin Link).
更新3：的现在，我显示吐司后 onStatusChanged得到一个强制关闭。可用。在（）。
Update #3: Now, I am getting a force close after displaying a Toast .."Available".. in on onStatusChanged().
更新＃4：的Finally..I得到它的工作。
Update #4: Finally..I got it to work.

结果那么，是不是像在谷歌地图的应用会使用一些专有code锁定到GPS信号？我一直在使用各种版本的我的code的尝试。尝试使用标准（S），但从来没有得到他们的GPS合作。对我来说，获得precise（〜50英尺精度），通过GPS定位坐标是必须的。

So, is it like that the Google map's app uses some proprietary code for locking on to GPS signals? I have tried using various version of my code. Tried using criteria(s) but never got them to work with GPS. For me getting precise (~50ft accuracy) location co-ordinates through GPS is a must.
我的code：
public class LocationDemoActivity extends Activity implements LocationListener {
LocationManager locationManager;
StringBuilder builder;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000l, 50.0f, this);
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
locationManager.removeUpdates(this);
locationManager = null;
Intent i = new Intent(
android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(i);
}
@Override
public void onLocationChanged(Location location) {
// builder = new StringBuilder();
double lati=location.getLatitude();
double longi=location.getLongitude();
double alti=location.getAltitude();
float acc=location.getAccuracy();
float speed=location.getSpeed();
long time=location.getTime();
System.out.println(lati);
System.out.println(longi);
System.out.println(alti);
System.out.println(acc);
System.out.println(speed);
System.out.println(time);
/*Toast.makeText(this, "Lati: " + lati,Toast.LENGTH_SHORT).show();
Toast.makeText(this, "Long: " + longi,Toast.LENGTH_SHORT).show();
Toast.makeText(this, "Alti: " + alti,Toast.LENGTH_SHORT).show();
Toast.makeText(this, "Acc.: " + acc,Toast.LENGTH_SHORT).show();
Toast.makeText(this, "Speed: " + speed,Toast.LENGTH_SHORT).show();
Toast.makeText(this, "Time: " + time,Toast.LENGTH_SHORT).show();*/
builder.append("Longitide: " + location.getLongitude());
builder.append('\n');
builder.append("Latitude: " + location.getLatitude());
builder.append('\n');
builder.append("Altitude: " + location.getAltitude());
builder.append('\n');
builder.append("Accuracy: " + location.getAccuracy());
builder.append('\n');
builder.append("TimeStamp:" + location.getTime());
builder.append('\n');
System.out.println(builder.toString());
Toast.makeText(this, builder.toString(), Toast.LENGTH_LONG).show();
}
@Override
public void onProviderDisabled(String provider) {
System.out.println("Provider Disabled:");
Intent intent = new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);
}
@Override
public void onProviderEnabled(String provider) {
System.out.println("Provider Enabled:");
Toast.makeText(this, "GPS is now enabled...", Toast.LENGTH_LONG).show();
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
switch (status) {
case LocationProvider.OUT_OF_SERVICE:
System.out.println("Status Changed: Out of Service");
Toast.makeText(this, "Status Changed: Out of Service",
Toast.LENGTH_SHORT).show();
break;
case LocationProvider.TEMPORARILY_UNAVAILABLE:
System.out.println("Status Changed: Temporarily Unavailable");
Toast.makeText(this, "Status Changed: Temporarily Unavailable",
Toast.LENGTH_SHORT).show();
break;
case LocationProvider.AVAILABLE:
System.out.println("Status Changed: Available");
Toast.makeText(this, "Status Changed: Available",
Toast.LENGTH_SHORT).show();
break;
}
}
}
请做答案，因为这是我和任何帮助非常迫切大大AP preciable：）
Please do answer as it's quite urgent on me and any help is greatly appreciable :)
谢谢..
推荐答案
我问一个相关的问题<一href=\"http://stackoverflow.com/questions/14641019/experience-of-location-services-on-android-using-gps-and-network-providers\">here.
要我看起来像你的GPS在手机上是不是能看到SAT的。你需要让你的办公室/家庭我们到露天。就我而言，我搬到了 NetworkProvider 因为GPS是太笨拙。
To me looks like your GPS on the phone is not able to see the sat's. You need to get our of your office/home onto open air. In my case, I moved to NetworkProvider since GPS was just too clumsy.
另外请注意，你给的距离和时间的参数都没有文字，其最好的猜测的API使。所以不要从API回调的响应时间/距离计数。
Also note, that the parameters you give for distance and time are not literal, its the best guess that the api makes. So dont count on response times/distances from the API callback.
