启动LocationManager作为服务机器人 [英] Starting LocationManager as Service Android
问题描述
我正在试图做的是当接收到C2DM消息，开始询问的位置的时候'X'量的服务，然后递给该位置关到我们的服务器。所述C2DM消息正确启动的服务，和GPS位置打开，但它从未更新。它只是坐在那里的时候，我指定螺纹长度（目前为12秒）和什么也不做。我使用的是完全相同的code别的地方我的应用程序（而不是作为服务）和它完美的作品。我究竟做错了什么？
What I'm attempting to do is when receiving a c2dm message, start a service that asks for location for 'x' amount of time and then hands that location off to our server. The c2dm message starts the service correctly, and the GPS location turns on, but it never updates. It just sits there for the length of time I specify (currently 12 seconds) in the thread and does nothing. I'm using the exact same code somewhere else in my app (not as a service) and it works perfectly. What am I doing wrong?
这时候接收C2DM消息启动该服务。
This starts the service when receiving a c2dm message.
context.startService(new Intent(context, ServicePingLocation.class));
这是在code的服务本身。所有这些曾经被称为是的onCreate和ONSTART。
This is the code for the service itself. All that ever gets called, is "onCreate" and "onStart".
public class ServicePingLocation extends Service implements LocationListener {
private final String DEBUG_TAG = "[GPS Ping]";
private boolean xmlSuccessful = false;
private boolean locationTimeExpired = false;
private LocationManager lm;
private double latitude;
private double longitude;
private double accuracy;
@Override
public void onLocationChanged(Location location) {
Log.d(DEBUG_TAG, "onLocationChanged");
latitude = location.getLatitude();
longitude = location.getLongitude();
accuracy = location.getAccuracy();
}
@Override
public void onProviderDisabled(String provider) {
Log.d(DEBUG_TAG, "onProviderDisabled");
Toast.makeText(
getApplicationContext(),
"Attempted to ping your location, and GPS was disabled.",
Toast.LENGTH_LONG).show();
}
@Override
public void onProviderEnabled(String provider) {
Log.d(DEBUG_TAG, "onProviderEnabled");
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 10000, 10f, this);
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
Log.d(DEBUG_TAG, "onStatusChanged");
}
@Override
public void onCreate() {
Log.d(DEBUG_TAG, "onCreate");
}
@Override
public void onDestroy() {
Log.d(DEBUG_TAG, "onDestroy");
}
@Override
public IBinder onBind(Intent intent) {
Log.d(DEBUG_TAG, "onBind");
return null;
}
@Override
public void onStart(Intent intent, int startid) {
Log.d(DEBUG_TAG, "onStart");
lm = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 10000, 10f, this);
lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 10000,
300f, this);
Log.d(DEBUG_TAG, lm.toString());
new SubmitLocationTask(ServicePingLocation.this).execute();
}
private void locationTimer() {
new Handler().postDelayed(new Runnable() {
// @Override
@Override
public void run() {
locationTimeExpired = true;
}
}, 12000);
}
private class SubmitLocationTask extends AsyncTask<String, Void, Boolean> {
/** application context. */
private Context context;
private Service service;
public SubmitLocationTask(Service service) {
this.service = service;
context = service;
}
@Override
protected void onPreExecute() {
locationTimer(); // Start 12 second timer
}
@Override
protected void onPostExecute(final Boolean success) {
if (success && xmlSuccessful) {
lm.removeUpdates(ServicePingLocation.this);
onDestroy();
} else {
if (!GlobalsUtil.DEBUG_ERROR_MSG.equals(""))
Toast.makeText(getBaseContext(),
GlobalsUtil.DEBUG_ERROR_MSG, Toast.LENGTH_SHORT)
.show();
GlobalsUtil.DEBUG_ERROR_MSG = "";
}
}
@Override
protected Boolean doInBackground(final String... args) {
try {
DateFormat df = null;
df = new SimpleDateFormat("M/d/yy h:mm a");
Date todaysDate = new Date();// get current date time with
// Date()
String currentDateTime = df.format(todaysDate);
while ((accuracy > 100f || accuracy == 0.0)
&& !locationTimeExpired) {
// We just want it to sit here and wait.
}
return xmlSuccessful = SendToServerUtil.submitGPSPing(
0, longitude,
latitude, accuracy, currentDateTime);
} catch (Exception e) {
return false;
}
}
}
}
修正了我遇到的问题。 code的实际工作。我增加了网络供应商，调整的onDestroy（）方法来停止服务，并调整用来抢的GPS信号的时间。
Fixed the issue I was having. Code was actually working. I added the network provider, adjusted the onDestroy() method to stop the service, and tweaked the time used to grab GPS signal.
