Latitudeあなたの場所を割り当て、longitudeデフォルトでそれがうまくいくかもしれないことを確認してください

これは私のために働いています:-)

Context ctx;

double LATITUDE = ; //your static latitude
double LONGITUDE = ; //your static longitude

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_landing);
        ctx = this;

         Geocoder geocoder = new Geocoder(this, Locale.getDefault());
    try {
          List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);
          if(addresses != null) {
               Address returnedAddress = addresses.get(0);
               StringBuilder strReturnedAddress = new StringBuilder();
           for(int i=0; i<returnedAddress.getMaxAddressLineIndex(); i++) {
               strReturnedAddress.append(returnedAddress.getAddressLine(i)).append("\n");
        }
           tvAddress.setText(strReturnedAddress.toString());
        }
          else {
           tvAddress.setText("No Address returned!");
        }
    } catch (IOException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
          tvAddress.setText("Canont get Address!");
        }
