在我的权限有:

推荐答案
这可能是与你的的不正确使用的String.format问题()
。有时候,这可能会导致奇怪的,特定于设备的问题。尝试,
It could be a problem with your incorrect usage of String.format()
. Sometimes this can cause weird, device-specific issues. Try,
String lon = "" + location.getLongitude();
String lat = "" + location.getLatitude();
String num = getMyPhoneNumber();
String message = String.format(
"New Location \n Longitude: %1$s \n Latitude: %2$s \n %3$s",
lon,
lat,
num
);
您是否尝试过用这个?
Have you tried using this?
LocationManager lm = (LocationManager)act.getSystemService(Context.LOCATION_SERVICE);
Criteria crit = new Criteria();
crit.setAccuracy(Criteria.ACCURACY_FINE);
String provider = lm.getBestProvider(crit, true);
Location loc = lm.getLastKnownLocation(provider);
