我使用三星手机通过 LocationManager API 获取位置,如果禁用 GPS,我无法获取位置,通过网络提供商我无法获取位置。
这是代码,这在 HTC 和索尼甚至禁用 GPS 时效果很好,但在三星手机中却不行。
public Location getLocation() {
try {
mLocationManager = (LocationManager)this.getSystemService(Context.LOCATION_SERVICE);
// getting GPS status
isGPSEnabled = mLocationManager
.isProviderEnabled(LocationManager.GPS_PROVIDER);
// getting network status
isNetworkEnabled = mLocationManager
.isProviderEnabled(LocationManager.NETWORK_PROVIDER); //fails in samsung phone returns NULL
if (isGPSEnabled == false && isNetworkEnabled == false) {
// no network provider is enabled
} else {
this.canGetLocation = true;
if (isNetworkEnabled) {
mLocationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER,
MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
if (mLocationManager != null) {
mLocation = mLocationManager
.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
}
}
// if GPS Enabled get lat/long using GPS Services
if (isGPSEnabled) {
if (mLocation == null) {
mLocationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
if (mLocationManager != null) {
mLocation = mLocationManager
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
return mLocation;
}
