地址的三级联动，老初始化失败，下面是我的代码，急求楼主！！！！

public static void chooseCity(final Activity activity, final OnResponse response) {
AddressPickTask task = new AddressPickTask(activity);
task.setHideProvince(false);
task.setHideCounty(false);
task.setCallback(new AddressPickTask.Callback() {
@Override
public void onAddressInitFailed() {
UIUtils.showToastSafe("数据初始化失败");
}

@Override
public void onAddressPicked(Province province, City city, County county) {
if (county == null) {
response.onSuccess(province.getAreaName() + city.getAreaName());
} else {
response.onSuccess(province.getAreaName() + city.getAreaName() + county.getAreaName());
}
}
});
task.execute("北京", "北京", "海淀");
}

private OnResponse response;

public void setOnResponse(OnResponse response) {
this.response = response;
}

public interface OnResponse {
void onSuccess(String result);
}
