Hi Amir,
Where did you test that code? Emulator or dev phone?

Mark is right.
Additionally, I suppose that cause of crash is null pointer exception.
>>> Double latPoint = myManager.getLastKnownLocation("gps").getLatitude
Here is.
If GPS is not working, the app doesn't have appropriate permissions or
the phone couldn't determine location, "getLastKnownLocation method"
return null.
If you test on emulator, you have to send location infomation to
emulator[adb] by DDMS.
If you test on dev phone, you would test below code.
----
Double latPoint = null;
Double lngPoint = null;
Location loc = myManager.getLastKnownLocation("gps");
if(loc != null) {
latPoint = myManager.getLastKnownLocation("gps").getLatitude();
lngPoint = myManager.getLastKnownLocation("gps").getLongitude();
} else {
Log.d("location", "location is null");
}
----
cheers,
keiji
