嗨已经创建了一个凌空程序，当我的应用程序运行时它工作正常...但是当应用程序关闭时，数据会发布到服务器但是它没有给出响应......来自服务器的代码是这样的方式...我已经把我所有的代码和这个运行在Intent服务所以请让我知道它出错的地方或者什么是凌空的问题
public class CapitalService extends IntentService{
NetworkInfo networkInfo;
Intent mServiceIntent;
Context context = this;
public CapitalService(){
super("Empty Constructor");
}
public CapitalService(String name) {
super(name);
}
@Override
protected void onHandleIntent(Intent intent) {
makeJsonObjectRequest();
}
private void makeJsonObjectRequest() {
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.POST,
"", obj, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
try {
response.getString("success");
final NotificationManager mgr=
(NotificationManager)CapitalService.this.getSystemService(Context.NOTIFICATION_SERVICE);
Notification note=new Notification(R.drawable.add_more,
"Android Example Status message!",
System.currentTimeMillis());
// This pending intent will open after notification click
PendingIntent i = PendingIntent.getActivity(CapitalService.this, 0,
new Intent(CapitalService.this, Home.class),
0);
note.setLatestEventInfo(CapitalService.this, "Android Example Notification Title",
"This is the android example notification message", i);
mgr.notify(2133, note);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
});
jsonObjReq.setRetryPolicy(new DefaultRetryPolicy(
0,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
AppController.getInstance().addToRequestQueue(jsonObjReq);
}
}
答案 0 :(得分：1)
onHandleIntent 也是一个帖子，所以你可以把你的代码放在 onHandleIntent 中而不需要任何函数，所以你的代码应该如下所示：
public class CapitalService extends IntentService{
NetworkInfo networkInfo;
Intent mServiceIntent;
Context context = this;
public CapitalService(){
super("Empty Constructor");
}
public CapitalService(String name) {
super(name);
}
@Override
protected void onHandleIntent(Intent intent) {
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.POST,
"", obj, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
try {
response.getString("success");
final NotificationManager mgr=
(NotificationManager)CapitalService.this.getSystemService(Context.NOTIFICATION_SERVICE);
Notification note=new Notification(R.drawable.add_more,
"Android Example Status message!",
System.currentTimeMillis());
// This pending intent will open after notification click
PendingIntent i = PendingIntent.getActivity(CapitalService.this, 0,
new Intent(CapitalService.this, Home.class),
0);
note.setLatestEventInfo(CapitalService.this, "Android Example Notification Title",
"This is the android example notification message", i);
mgr.notify(2133, note);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
});
jsonObjReq.setRetryPolicy(new DefaultRetryPolicy(
0,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
AppController.getInstance().addToRequestQueue(jsonObjReq);
}
}
或者你可以使用 asycktask 像这样：
@Override
protected void onHandleIntent(Intent intent) {
List<NameValuePair> params = new ArrayList<NameValuePair>();
SharedPreferences prefs = getSharedPreferences("CommonPrefs", Activity.MODE_PRIVATE);
String user_id = prefs.getString("user_id", "");
String last_1 = prefs.getString("last_id_general_news", "");
String last_2=prefs.getString("last_id_local_news", "");
String last_3=prefs.getString("last_id_events", "");
String last_4=prefs.getString("last_id_gas", "");
params.add(new BasicNameValuePair("user_id", user_id));
params.add(new BasicNameValuePair("cat_1", last_1));
params.add(new BasicNameValuePair("cat_2",last_2));
params.add(new BasicNameValuePair("cat_3",last_3));
params.add(new BasicNameValuePair("cat_4", last_4));
JSONObject json = jParser.getJSONFromUrl(RestClient.URL_NOTIFICATION, params);
try {
JSONArray jsonArray = json.getJSONArray("request");
