我Location Manager
在我的应用程序中使用 GPS 跟踪。Android
该应用程序在2.2、2.3.3 模拟器和设备中使用时返回 apt 位置。但是,奇怪的是我在Emulator 4.0.2中测试了该应用程序。它返回与logcat05-28 15:13:46.584: E/AndroidRuntime(4458): at com.package.TestRun.registerLocationListeners(TestRun.java:191)
中一样的强制关闭错误。我已经实现了如下代码:
LocationManager lm;
LocationManager lmNet;
private void registerLocationListeners() {
lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
if (myGPSLocationListener == null || mynetworkprovider == null)
{
createLocationListeners();
}
lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER ,0,0,mynetworkprovider);
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER ,60000,0,myGPSLocationListener);
}
private void createLocationListeners() {
mynetworkprovider = new LocationListener() {
public void onLocationChanged(Location argLocation) {
if (argLocation != null) {
gps[0] = argLocation.getLatitude();
gps[1] = argLocation.getLongitude();
//Toast.makeText( getApplicationContext(),"Network provider Lat =" + gps[0] + " Lon = " + gps[1] , Toast.LENGTH_SHORT).show();
}
//Toast.makeText( getApplicationContext(),"On Location change" , Toast.LENGTH_SHORT).show();
}
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
// Toast.makeText( getApplicationContext(),"Disable" , Toast.LENGTH_SHORT).show();
}
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
// Toast.makeText( getApplicationContext(),"enabled" , Toast.LENGTH_SHORT).show();
}
public void onStatusChanged(String provider,
int status, Bundle extras) {
// TODO Auto-generated method stub
//Toast.makeText( getApplicationContext(),"Status change" , Toast.LENGTH_SHORT).show();
}
};
myGPSLocationListener = new LocationListener() {
public void onLocationChanged(Location argLocation) {
if (argLocation != null) {
gps[0] = argLocation.getLatitude();
gps[1] = argLocation.getLongitude();
//Toast.makeText( getApplicationContext(),"GPS Lat =" + gps[0] + " Lon = " + gps[1] , Toast.LENGTH_SHORT).show();
}
//Toast.makeText( getApplicationContext(),"On Location change" , Toast.LENGTH_SHORT).show();
}
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
//Toast.makeText( getApplicationContext(),"Disable" , Toast.LENGTH_SHORT).show();
//launchGPS();
}
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
//Toast.makeText( getApplicationContext(),"enabled" , Toast.LENGTH_SHORT).show();
}
public void onStatusChanged(String provider,
int status, Bundle extras) {
// TODO Auto-generated method stub
//Toast.makeText( getApplicationContext(),"Status change" , Toast.LENGTH_SHORT).show();
}
};
}
