我有这两个班级：
public class EmailManager {
private RetrieveEmailResultTask retrieveEmailResultTask;
public EmailManager(SMSAndEmailResponseListener smsAndEmailResponseListener) {
retrieveEmailResultTask = new RetrieveEmailResultTask();
retrieveEmailResultTask.SMSAndEmailResponseListener = smsAndEmailResponseListener;
}
public void send(String subject, String body, String nonHTMLBody) throws IOException{
String uri = "subject=" + Utils.encode(subject);
uri += "&body=" + Utils.encode(body);
uri += "&non_html_body=" + Utils.encode(nonHTMLBody);
retrieveEmailResultTask.execute(uri);
}
public Exception getException() {
return retrieveEmailResultTask.e;
}
private class RetrieveEmailResultTask extends AsyncTask<String, Void, Boolean> {
protected Exception e;
protected SMSAndEmailResponseListener SMSAndEmailResponseListener = null;
@Override
protected Boolean doInBackground(String... strings) {
try {
URL url = new URL("http://tarzz.com.pk/emailapi/sendemail.php");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());
writer.write(strings[0]);
writer.flush();
BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String res = rd.readLine();
Log.d("YOLO", res);
writer.close();
rd.close();
if(res != "Message has been sent") {
return false;
}
} catch (MalformedURLException e) {
e.printStackTrace();
this.e = e;
return false;
} catch (IOException e) {
e.printStackTrace();
this.e = e;
return false;
}
return true;
}
@Override
protected void onPostExecute(Boolean aBoolean) {
this.SMSAndEmailResponseListener.onResult(aBoolean);
}
}
}
和
public class SMSManager {
private RetrieveSMSResultTask retrieveSMSResultTask;
public SMSManager(SMSAndEmailResponseListener SMSAndEmailResponseListener) {
retrieveSMSResultTask = new RetrieveSMSResultTask();
retrieveSMSResultTask.SMSAndEmailResponseListener = SMSAndEmailResponseListener;
}
public void send(String to, String msg) throws IOException {
String uri = "id=" + Utils.encode("rchibltarzz");
uri += "&pass=" + Utils.encode("karachi1");
uri += "&msg=" + Utils.encode(msg);
uri += "&lang=" + Utils.encode("English");
uri += "&to=" + Utils.encode(to);
uri += "&mask=" + Utils.encode("Tarzz");
uri += "&type=" + Utils.encode("json");
retrieveSMSResultTask.execute(uri);
}
public Exception getException() {
return retrieveSMSResultTask.e;
}
private class RetrieveSMSResultTask extends AsyncTask<String, Void, Boolean> {
protected Exception e;
protected SMSAndEmailResponseListener SMSAndEmailResponseListener = null;
@Override
protected Boolean doInBackground(String... urls) {
try {
URL url = new URL("http://www.outreach.pk/api/sendsms.php/sendsms/url");
URLConnection con = url.openConnection();
con.setDoOutput(true);
OutputStreamWriter writer = new OutputStreamWriter(con.getOutputStream());
writer.write(urls[0]);
writer.flush();
BufferedReader rd = new BufferedReader(new InputStreamReader(con.getInputStream()));
String line = "", res = "";
while ((line = rd.readLine()) != null) {
res += line + " ";
}
writer.close();
rd.close();
JSONObject jsonObj = new JSONObject(res);
JSONArray jsonArray = jsonObj.optJSONArray("corpsms");
JSONObject response = jsonArray.getJSONObject(0);
Log.d("YOLO", (String) response.get("type"));
if(((String) response.get("type")).equals("Success")) {
return true;
} else {
return false;
}
} catch(IOException e) {
e.printStackTrace();
this.e = e;
return false;
} catch (JSONException e) {
e.printStackTrace();
this.e = e;
return false;
}
}
@Override
protected void onPostExecute(Boolean aBoolean) {
this.SMSAndEmailResponseListener.onResult(aBoolean);
}
}
}
这是我的倾听者：
public interface SMSAndEmailResponseListener {
void onResult(Boolean a);
}
这就是我在主要活动中使用这些类的方法：
@Override
public void onResult(Boolean a) {
if(a == true) {
Toast.makeText(getApplicationContext(), "Your feedback has been submitted. Thanks for your cooperation.", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(), "An error occurred in submitting your application. Please try again.", Toast.LENGTH_SHORT).show();
}
}
和
btnSubmit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
try {
smsManager.send(etMobileNumber.getText().toString(), "Your feedback has been submitted. Thanks for your cooperation.");
emailManager.send("Feedback from customer", emailBody, "Non Html");
} catch (IOException e) {
e.printStackTrace();
}
}
});
每当我尝试运行我的应用程序时，都会显示以下错误：

我不知道我做错了什么，为什么AsyncTask没有工作。请告诉我。谢谢。 ：）
