AM using AsyncTask to retrieve data from services. but it taking too much time i.e., about 2 mins or so ..
I found out that, when i start the asynctask the dialog show is showing but background process taking time to respond and getting data.
Check my code of asynctask:
public class JamsTask extends AsyncTask<Void,Void,Bundle>
{
private Context ctx;
ProgressDialog dlg;
Bitmap userImage;
String message ;
public JamsTask(Context context) {
ctx = context;
}
@Override
protected void onPreExecute() {
//super.onPreExecute();
try{
dlg = new ProgressDialog(Jams.this);
dlg.setMessage("Please wait....");
dlg.show();
}catch (Exception e) {
// TODO: handle exception
}
//setContentView(R.layout.splash);
}
@Override
protected Bundle doInBackground(Void... params) {
Bundle b=new Bundle();
try{
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("fkPersonId", Integer.valueOf(JujamaMain.userValues.get(0)));
request.addProperty("fkConferenceId", Integer.valueOf(JujamaMain.userValues.get(4)));
request.addProperty("startIndex",1);
request.addProperty("endIndex",20);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet=true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(SOAP_ACTION, envelope);
Object result= envelope.getResponse();
SoapObject response=(SoapObject)envelope.bodyIn;
strRes = result.toString();
SoapObject returnObj = (SoapObject)response.getProperty("GetAllStatusUpdatesResult");
SoapObject object=(SoapObject) returnObj.getProperty(1);
SoapObject returnObj2 = (SoapObject)object.getProperty("NewDataSet");
// Integer id = Integer.valueOf(returnObj.getPropertySafelyAsString("id");
for(int i=0;i<returnObj2.getPropertyCount();i++) {
SoapObject persondetails = (SoapObject)returnObj2.getProperty(i);
String salution = (String)persondetails.getPropertySafelyAsString("Salutation","");
//String companyname = (String)persondetails.getPropertySafelyAsString("CompanyName");
String firstname = (String)persondetails.getPropertySafelyAsString("FirstName","");
String lastname = (String)persondetails.getPropertySafelyAsString("LastName","");
if(!persondetails.getPropertySafelyAsString("Message","").contains("anyType"))
message = (String)persondetails.getPropertySafelyAsString("Message","");
else
message=""
;
String nameID = (String)persondetails.getPropertySafelyAsString("PKStatusID","");
String fkconfid = (String)persondetails.getPropertySafelyAsString("FKConferenceID","");
try{
SimpleDateFormat form = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
java.util.Date date = null;
String sub=commented.substring(0, 19);
date = form.parse(sub);
SimpleDateFormat postFormater =new SimpleDateFormat("MMMMM dd, yyyy, HH:mm");
String newDateStr = postFormater.format(date);
mTimedifference.add(newDateStr);
/* DateTime myBirthDate = new DateTime(year,month, day, hour, minute, 0, 0);
DateTime now = new DateTime();
Period period = new Period(myBirthDate, now);
PeriodFormatter formatter = new PeriodFormatterBuilder()
.appendYears().appendSuffix(" years, ")
.appendMonths().appendSuffix(" months, ")
.appendWeeks().appendSuffix(" weeks, ")
.appendDays().appendSuffix(" days, ")
.appendHours().appendSuffix(" hours, ")
.appendMinutes().appendSuffix(" minutes, ")
.printZeroNever()
.toFormatter();
String elapsed = formatter.print(period);
System.out.println(elapsed + " ago");*/
}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
// System.out.println(".."+"dat"+now+"..."+time);
mNameID.add(nameID);
String ImageUrl = (String)persondetails.getPropertySafelyAsString("PhotoGuid","");
String liked = (String)persondetails.getPropertySafelyAsString("Liked","No");
String nocomments = (String)persondetails.getPropertySafelyAsString("NoofComments","0");
mName.add(firstname.toString()+lastname.toString()+salution.toString());
mMessages.add(message.toString());
mLikesCount.add(likescount.toString());
mLikeText.add(liked);
mNoComments.add(nocomments);
userImage=getBitmapFromURL("http://test.jujama.com/uploadfiles/"+ImageUrl);
Bitmap bmp=BitmapFactory.decodeResource(getResources(),R.drawable.nophoto);
if(userImage==null)
mUserImage.add(bmp);
else
mUserImage.add(userImage);
}
} catch (Exception e) {
e.printStackTrace();
}
return b;
}
@Override
protected void onPostExecute(Bundle b) {
dlg.dismiss();
lv.setAdapter(new Viewadapter(Jams.this));
}
}
Is there any way to reduce the time . because its too much time.
and one more:
bfore it starts:this below types of lines are coming .
GC_FOR_MALLOC freed 31921 objects / 2006888 bytes in 100ms
Thanks
It is hard to tell why from looking at your code why it is so slow. The best guess would be that you are, I believe, doing two web requests (once of which is fetching an image). It could be that your services are just very slow.
The log lines you posted above mean you are allocating memory. If you are doing something memory intensive you can expect to see a lot of them.
It is also possible that you have a lot of other threads going and the AsyncTask thread has lower priority than the other threads and is then essentially blocked by them. Try raising its priority (no idea how to do) or carefully look at the other threads in your code.
