how to get url with different ids in android (async task)

EDIT: Found the solution to my problem.
The json string output returned the wrong url for my local images.
i am barely new to android and struggle with asyncTask.
What i want is to get the corresponding image to a marker on a map.
every entry on this map has its own image which has to be loaded from server via json.
the image load works fine but i dont get the right workflow to get the image i need for one entry.
by now i have one solution to load an async task in a for-loop, but this cant be the right way because the app refuses to go on after 43 tasks and stops with
"ECONNECTION TIMEOUT"
so how can get the asynctask out of the loop?
hope anyone can help? thank you!

Your problem maybe AsyncTask limitations. In android.os.AsyncTask.java you will see core size and blockingqueue size(128), should use counter for asynctask and debug it(Problem is, lots of async tasks or other).
AsyncTask.java
public abstract class AsyncTask<Params, Progress, Result> {
private static final String LOG_TAG = "AsyncTask";
private static final int CPU_COUNT = Runtime.getRuntime().availableProcessors();
private static final int CORE_POOL_SIZE = CPU_COUNT + 1;
private static final int MAXIMUM_POOL_SIZE = CPU_COUNT * 2 + 1;
private static final int KEEP_ALIVE = 1;
private static final ThreadFactory sThreadFactory = new ThreadFactory() {
private final AtomicInteger mCount = new AtomicInteger(1);
public Thread newThread(Runnable r) {
return new Thread(r, "AsyncTask #" + mCount.getAndIncrement());
}
};
private static final BlockingQueue<Runnable> sPoolWorkQueue =
new LinkedBlockingQueue<Runnable>(128);
...}
Change Your Code Use Buffer(RequestData) And Use Only One Async Task. Update Market instance every publishProgress in onProgressUpdate

Please I need assistance, and moreover it fetches the data but on the map activity i.e, servicing activity the toast delivers nothing, once you press back and then again on button to start servicing activity, the toast delivers previous results, but no route can be seen on map.

I found solution, basically, I was calling route.drawroute(), before adding the points to the list, so it was returning null.

Google Places Details search System.err

I'm attempting to locate a restaurant by name using an AutoCompleteTextView which successfully obtains the places id. I've also checked the http request manually in my browser which responds with the correct information. When this code is executed, a system.err is shown in the LogCat console in Eclipse. My code below;

The googlePlaces example =
https://maps.googleapis.com/maps/api/place/details/json?placeid=ChIJCSWGvY-FdUgRpGdg10FTIIg&key="MY_API_KEY"
Is it obvious to anyone why no markers are being placed on my map fragment?
Errors from LogCat:
http://pastebin.com/T1AFbw3s
Google Maps and Markers class:
http://pastebin.com/hT2XwuE2

The error you are having is due to parsing the Json incorrectly at line 193 of GoogleMap activity:
JSONArray placesArray = resultObject.getJSONArray("results");
I believe the key is result instead of results.
I can give you a better explanation if I could see the json response. Meanwhile,
I would also suggest you to use Gson Library to parse the json responses to objects instead of mapping them manually. It would be alot easier.
Markers need to be added manually:
private void addMarker(String name, double lat, double long){
LatLng latlong = LatLng.newInstance(lat, long);
MarkerOptions markerOptions = MarkerOptions.newInstance();
markerOptions.setIcon(Icon.newInstance("/img/icon.png"));
markerOptions.setTitle(name);
Marker marker = new Marker(latlong, markerOptions);
map.addOverlay(marker);
}

It turns out that because I was using the same code to add markers onto the Map, when the detail search was used to identify a single place, the JSONArray type was incompatible with the result set... If that makes sense.
I had to separate the two by checking if a nearby search was being performed or a details search. Below was the code for the details search only:
resultObject = resultObject.getJSONObject("result"); // <---
places = new MarkerOptions[1];
LatLng placeLL = null;
String placeName = "";
String vicinity = "";
try {
JSONObject placeObject = resultObject;
JSONObject loc = placeObject.getJSONObject(
"geometry").getJSONObject("location");
placeLL = new LatLng(Double.valueOf(loc
.getString("lat")), Double.valueOf(loc
.getString("lng")));
vicinity = placeObject.getString("vicinity");
placeName = placeObject.getString("name");
} catch (JSONException jse) {
missingValue = true;
jse.printStackTrace();
}
if (missingValue){
result = null;
} else {
places[0] = new MarkerOptions().position(placeLL)
.title(placeName).snippet(vicinity);
}

Problems while displaying path between two points in google maps

This problem may sound a little weird, but whenever I run the app it crashes and when I change the name of LatLang variable in the function private LatLng getCurrentLocation(), It starts working. But when I change anything(even in any other file) it crashes and I have to keep changing the variable names to keep it running.
I am sure of the problem, it is something related to LatLang variable.

If you are sure that this line
nameArr = handler.getnameArr();
gives the NPE then you know the problem must be that handler is null at this point. That is the only way this line will throw a NPE. And from looking at that massive code, it definitely looks like handler is not instantiated before you call the method that uses it (getArrayLists();). You declare it here
XmlParserHandlerFinal handler;
but you never give it a value before trying to use it.
You will need to instantiate it in this Activity before calling a method on it such as getnameArr();. You instantiate it in the other Activity but not in this one.
