0

I’m creating a custom calendar for an Android app. The way it works now is that it pulls events from an online MySQL database, transfers them into a JSONArray, and inputs them into the calendar from there. It was working fine (if a bit slow) on an emulator, but today I hooked up my S3 and it’s giving me errors that I haven’t received before. The errors I’m getting in my log say:

09-14 22:52:12.611: E/dalvikvm(4605): threadid=2: stuck on threadid=1, giving up

09-14 22:52:12.611: E/dalvikvm(4605): Fatal spin-on-suspend, dumping threads

This is the ASyncTask that it keeps getting hung up on:

package com.legends.app;

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;

import org.apache.http.HttpEntity;

import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.json.JSONArray;
import android.os.AsyncTask;
import android.util.Log;

public class Events extends AsyncTask<Void, Void, String> {

    JSONArray jArray;
    public String result = null;
    InputStream is = null;
    StringBuilder sb=null;
    HttpEntity entity;

    protected String doInBackground(Void... arg0) {

          //http post - calls from the php file that opens the DB
          try{

               HttpClient httpclient = new DefaultHttpClient();
               HttpPost httppost = new HttpPost("http://legendsofnotredame.org/club/mobile/android/cal.php");
               HttpResponse response = httpclient.execute(httppost);

               entity = response.getEntity();

               }catch(Exception e){
                   Log.e("log_tag", "Error in http connection"+e.toString());
              }


          //convert response to string
            try{

                is = entity.getContent();

                BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);

                 sb = new StringBuilder();

                 sb.append(reader.readLine() + "\n");                 

                 String line="0";
                 while ((line = reader.readLine()) != null) {
                                sb.append(line + "\n");
                  }
                  is.close();
                  result=sb.toString();
                  }catch(Exception e){
                        Log.e("log_tag", "Error converting result "+e.toString());
                  }
            Log.e("test","Converted results to string");
            return result;
    }

    protected void onPostExecute(String result) {


    }

}

After adding a ton of logs, I determined that it was getting hung up on “sb.append(reader.readLine() + “\n”);”, and I’m not sure how to make it not do that. Any tips?

Edit: Here’s the (almost) full logcat for running it, starting from where it hangs on readLine. I had to cute out some non-warning/non-error lines at the beginning because this post is too long, sorry!

I figured it out after another day of playing around with it. It was timing out because of these lines in the non-AsyncTask:

while (db.result == null) {
    continue;
}

It took this as “you’re caught forever in a while loop and therefore the program must have crashed”, when in reality it was just taking time to read the events. However, without that there it would just move on without having fully loaded the events, creating a NullPointerException when it tries to use that array. What I did instead was do this:

while (db.result == null){
   try {
      Thread.sleep(100);
   } catch (InterruptedException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
   }
   continue;
}

The sleeping seems to send back to the app that I’m still there, just waiting for the data so I can continue. Either that or it slows down the amount of times I go through the while loop. Not sure which one it does but either way it solves the problem.
