反向地理编码未显示地址

Question

此代码显示无法获取地址。 是否有可能从纬度和经度获取地址？ 会是什么原因？

我一直在尝试许多类似的代码，但我无法做到。我也试过以下网站解决方案。但没什么用的。

              for(int i=0; i<fetchedAddress.getMaxAddressLineIndex(); i++) {

              }

              myAddress.setText("I am at: " +strAddress.toString());

          }

          else

    }

             e.printStackTrace();
             Toast.makeText(getApplicationContext(),"Could not get address..!", Toast.LENGTH_LONG).show();
    }
}
