I am new to Asynctask coding, and am having some issues.
In my code I have defined a subclass in an onClick listener, and in that class I have created an Asynctask which is using HTTP connections, and has some XML parsing code. The problem is, when I click on my button it is not waiting for the asynch task to complete, and instead it gives an error saying "Out of Bound in main class". There is no opportunity to process my PostExecute because XML parsing in the Async task throws an exception like: "NetworkOnMainThread".
I could really use some help uncovering my bug, here is my code:
public class GetDirectoryInfoXMLParser {
public static ArrayList<GetDirectoryInfoTableContent> tableContent;
private GetDirectoryInfoTableContent table;
private Thread alertThread;
private ProgressDialog progressDialog;
Context context;
InputStream is;
public GetDirectoryInfoXMLParser(SettingsPage settings) {
this.context = settings;
}
public void getDataFromUrl(String webSite) throws XmlPullParserException,
IOException {
if (webSite != null) {
alert(context);
GetDirectoryInfoAsyncTask gDirectoryInfoAsyncTask = new GetDirectoryInfoAsyncTask();
gDirectoryInfoAsyncTask.execute(webSite);
} else {
}
}
private class GetDirectoryInfoAsyncTask extends
AsyncTask<String, Void, String> {
@Override
protected String doInBackground(String... params) {
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(
"http://mobile.primemrm.com/mobile.asmx/GetDirectoryInfo");
ProtocolVersion protocolVersion = post.getProtocolVersion();
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("sUrl", params[0]));
try {
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse httpResponse = client.execute(post);
HttpEntity entity = httpResponse.getEntity();
is = entity.getContent();
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
XmlPullParserFactory factory;
try {
factory = XmlPullParserFactory.newInstance();
factory.setNamespaceAware(true);
XmlPullParser parser = factory.newPullParser();
// InputStream is = getURlResponse(params[0]);
if (is == null) {
Log.e("GetDirectoryInfoXMLParser", "InputStream is Null");
return null;
}
else if (is != null) {
Log.e("GetDirectoryInfoXMLParser",
"InputStream is Not Null");
parser.setInput(new InputStreamReader(is));
}
int eventType = parser.getEventType();
String name;
while (eventType != XmlPullParser.END_DOCUMENT) {
if (eventType == XmlPullParser.START_DOCUMENT) {
tableContent = new ArrayList<GetDirectoryInfoTableContent>();
} else if (eventType == XmlPullParser.START_TAG) {
name = parser.getName();
if (name.equalsIgnoreCase("Table")) {
table = new GetDirectoryInfoTableContent();
/*

* ("id")){
* table.setId(parser.getAttributeValue(i)); }else

*/
} else if (name
.equalsIgnoreCase("EnablePublicMemberDirectory")) {
table.setEnablePublicMemberDirectory(parser
.nextText());
Log.e("GetDirectoryInfoXMLParser",
"EnablePublicMemberDirectory : "
+ table.getEnablePublicMemberDirectory());
} else if (name.equalsIgnoreCase("Response")) {
table.setEnablePublicMemberDirectory(parser
.nextText());
}
} else if (eventType == XmlPullParser.END_TAG) {
name = parser.getName();
if (name.equalsIgnoreCase("Table")) {
tableContent.add(table);
table = null;
}
}
eventType = parser.next();
}
} catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
}
public void alert(final Context context) {
progressDialog = ProgressDialog.show(context, "", "Loading...");
alertThread = new Thread() {
@Override
public void run() {
try {
sleep(5000);
progressDialog.dismiss();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
};
alertThread.start();
}
}
Thanks In advance.
