我对android很新，我正在创建一个活动，它有两个微调器，它们从两个独立的API调用接收的JSONObjects中填充它们的下拉项。出于某种原因，我收到此错误。我不知道为什么我收到此错误或如何解决它。任何人都可以对此有所了解吗？任何帮助将不胜感激！！！这是我的代码：
public class AddPropertyActivity extends AppCompatActivity {
private TextView selectCity;

task1 = new DownloadJSON("http://xyz", 1);
task1.execute();
task2 = new DownloadJSON("http://xxx" + selectedCity,2 );
task2.execute();
}
private class DownloadJSON extends AsyncTask<Void, Void, Void> {

public DownloadJSON( String URL, int ch) {

}
@Override

jsonObject = JSONfunctions.getJSONfromURL(mURL);
if (mURL.equals("http://xyz")) {
try {

Log.d(TAG, "Number of entries " + jsonArray.length());
for (int i = 0; i < jsonArray.length(); i++) {

mCity.setName(jsonObject.optString("locationTitle"));
mCity.setId(jsonObject.getInt("id"));

}
} catch (Exception e) {

}
} else {
