    copied!<p>I'm currently working with an async task that parses a JSON string. Once the string is parsed and the task from doInBackground() moves on to postExecute() it's giving me this error:</p> <pre><code>06-17 20:19:53.612: E/AndroidRuntime(591): FATAL EXCEPTION: main 06-17 20:19:53.612: E/AndroidRuntime(591): java.lang.NumberFormatException: unable to parse 'null' as integer 06-17 20:19:53.612: E/AndroidRuntime(591): at java.lang.Integer.parseInt(Integer.java:356) 06-17 20:19:53.612: E/AndroidRuntime(591): at java.lang.Integer.parseInt(Integer.java:332) 06-17 20:19:53.612: E/AndroidRuntime(591): at stefan.testservice.ParkingActivity$DownloadTask.onPostExecute(ParkingActivity.java:258) 06-17 20:19:53.612: E/AndroidRuntime(591): at android.os.AsyncTask.finish(AsyncTask.java:417) 06-17 20:19:53.612: E/AndroidRuntime(591): at android.os.AsyncTask.access$300(AsyncTask.java:127) 06-17 20:19:53.612: E/AndroidRuntime(591): at android.os.AsyncTask$InternalHandler.handleMessage(AsyncTask.java:429) 06-17 20:19:53.612: E/AndroidRuntime(591): at android.os.Handler.dispatchMessage(Handler.java:99) 06-17 20:19:53.612: E/AndroidRuntime(591): at android.os.Looper.loop(Looper.java:123) 06-17 20:19:53.612: E/AndroidRuntime(591): at android.app.ActivityThread.main(ActivityThread.java:3683) 06-17 20:19:53.612: E/AndroidRuntime(591): at java.lang.reflect.Method.invokeNative(Native Method) 06-17 20:19:53.612: E/AndroidRuntime(591): at java.lang.reflect.Method.invoke(Method.java:507) 06-17 20:19:53.612: E/AndroidRuntime(591): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:839) 06-17 20:19:53.612: E/AndroidRuntime(591): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:597) 06-17 20:19:53.612: E/AndroidRuntime(591): at dalvik.system.NativeStart.main(Native Method) </code></pre> <p>It was working perfectly before, just all of a sudden it's seems to have some problem with the 'return null' statement at the end of the async task. I can't seem to find a solution. Thanks in advance.</p> <p>My code snippet:</p> <pre><code>private class DownloadTask extends AsyncTask&lt;String, Void, Object&gt; { @Override protected Object doInBackground(String... args) { Log.i("MyApp", "Background thread starting"); Global.url = "http://10.0.2.2:8000/CarServiceScheduling1/resources/json/product/getpark?degree="+degreeStatus+"&amp;year="+yearStatus+"&amp;distance="+distance+"&amp;devid="+Global.android_id; try{ statusCode = cg.connection(); }catch (Exception e) { test_connection = true; } if(test_connection == false){ try { output = cg.stringconverter(Global.data); cg.parseGson(output); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } return null; } protected void onPostExecute(Object result) { if (ParkingActivity.this.progressDialog != null) { ParkingActivity.this.progressDialog.dismiss(); if(CheckboxPreference == true &amp;&amp; Integer.parseInt(Global.preference1) == 0 &amp;&amp; Integer.parseInt(Global.preference2) == 0 &amp;&amp; (Global.status.equalsIgnoreCase("No Slots available") || Global.status.equalsIgnoreCase("No"))){ Intent searchSubActivity = new Intent(getBaseContext(), Nospotsactivity.class); startActivity(searchSubActivity); } else if (CheckboxPreference == true &amp;&amp; (Integer.parseInt(Global.preference1) != 0 || Integer.parseInt(Global.preference2) != 0 )){ Intent searchSubActivity = new Intent(getBaseContext(), Spotsfoundactivity.class); startActivity(searchSubActivity); } else if(CheckboxPreference == false &amp;&amp; (Integer.parseInt(Global.preference1) != 0 || Integer.parseInt(Global.preference2) != 0 )){ Intent searchSubActivity = new Intent(getBaseContext(), Spotsfoundactivity.class); startActivity(searchSubActivity); } if(Integer.parseInt(Global.preference1) == 0 &amp;&amp; Integer.parseInt(Global.preference2) == 0){ if(Global.status.equalsIgnoreCase("Hardly Likely")){ Intent searchSubActivity = new Intent(getBaseContext(), Unlikelyactivity.class); startActivity(searchSubActivity); } else if(Global.status.equalsIgnoreCase("Likely")){ Intent searchSubActivity = new Intent(getBaseContext(), Likelyactivity.class); startActivity(searchSubActivity); } } } } } } } </code></pre>
