我正在尝试使用 htc hope c 反转地理编码,在运行应用程序时,它的抛出服务不可用异常。但是 GeoCoder.isPresent() 正在返回“真”。请帮助我找出问题所在。
这是我的代码:
public class MainActivity extends Activity {
LocationManager lManager;
String provider;
Location location ;
@SuppressLint("NewApi")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
provider = lManager.getBestProvider(criteria, false);
if(provider!=null && !provider.equals("")){
// Get the location from the given provider
location = lManager.getLastKnownLocation(provider);
}
boolean geoCoder = false;
Geocoder geo = new Geocoder(this, Locale.getDefault());
geoCoder = Geocoder.isPresent();
System.out.println("GEO CODER : "+geoCoder);
try {
List<Address> address = geo.getFromLocation(location.getLatitude(), location.getLongitude(), 3);
System.out.println("Size------------- "+address.size());
/*Address addr = address.get(0);
System.out.println("City "+addr.getLocality());*/
} catch (IOException e) {
// TODO Auto-generated catch block
System.out.println("in here--------------");
e.printStackTrace();
}
}
