how to implement search by address location on Google Map in fragment.Please tell me..
enter error description here

You can do it in another way.
You can generate an api key along with Google maps & Google places api in your developers console (Click on the circled link and Enable the api)
You can call the api like below with your AutoCompleteView onclick listener or any other listener of your wish
private int PLACE_AUTOCOMPLETE_REQUEST_CODE = 1;// declare this globally
//Call this on your listener method
Intent intent = new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY)
.build(getActivity());
startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_CODE);
This will open the Google place search screen and you can get the result like below
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PLACE_AUTOCOMPLETE_REQUEST_CODE) {
if (resultCode == getActivity().RESULT_OK) {
Place place = PlaceAutocomplete.getPlace(getActivity(), data);
mSearchPlace = place;
mSearchText.setText(String.valueOf(place.getName()));
// You will get Lat,Long values here where you can use it to move your map or reverse geo code it.
LatLng latLng = new LatLng(place.getLatLng().latitude, place.getLatLng().longitude);
mGoogleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng, 12));
} else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
Status status = PlaceAutocomplete.getStatus(getActivity(), data);
} else if (resultCode == getActivity().RESULT_CANCELED) {
// The user canceled the operation.
}
}
}
Hope this helps.

my app is crash when i enter any word after provide space in autocompletetextview and then again when i enter any word then its crash....

Your list is initialized to null at
List<HashMap<String, String>> list = null;
And if the parsing fire any exception, the list will be still null since it won't get initialized & setting a null List to an adapter will produce the NullPointerException at getCount(). So just ensure to initialize it.
List<HashMap<String, String>> list = new ArrayList<>();
IMPORTANT
When you use a space & try to call that URL, it will fire a FileNotFoundException if not encoded properly. In your case, URL url = new URL(strUrl); is firing that exception while using space character.
Easiest way is to replace space with %20. In getAutoCompleteUrl() before return, put the following code to replace space with %20.
private String getAutoCompleteUrl(String place) {
-------existing code----
url = url.replaceAll(" ", "%20");
return url;
}

Actually i had faced the same situation. You are adding data to autocomplete textview dynamically , basically just like google for each word you are typing u are getting that data from server , if i am wrong please correct me.
Use this code for populating data into autocomplete textview dynamically from server depending upon your search

replace mine code of getting data from server to yours i.e calling webservices through http calls and it will work like a charm.

int ClikedPosition, long id) {
//Getting clicked item from list view
mSelectedItem=adapter.getItem(ClikedPosition);
//Setting to auto complete text view

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() {

return new Thread(r, "AsyncTask #" + mCount.getAndIncrement());
}
};
private static final BlockingQueue<Runnable> sPoolWorkQueue =

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;
public class AdvancedSearch extends Activity implements OnItemClickListener {
private static final String LOG_TAG = "com.lw276.justdine";
private static final String PLACES_API_BASE = "https://maps.googleapis.com/maps/api/place";
private static final String TYPE_AUTOCOMPLETE = "/autocomplete";
private static final String OUT_JSON = "/json";
// ------------ make your specific key ------------
private static final String API_KEY = "MyAPIKEY";
private Activity context = this;
static HashMap<String, String> place;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_advanced_search);
final AutoCompleteTextView autoCompView = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView);
autoCompView.setAdapter(new GooglePlacesAutocompleteAdapter(this,
R.layout.list_item));
autoCompView.setOnItemClickListener(this);
Button btnAdvancedSearch = (Button) findViewById(R.id.advanced_search_btn);
btnAdvancedSearch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String str = autoCompView.getText().toString();
if(place.containsKey(str)){
String placeId = place.get(str);
Log.d("advancedSearchBtn: placeId = ", placeId);
Log.i("advancedSearchBtn", "Search button has been pressed");
Intent i = new Intent(context, GoogleMap.class);
i.putExtra("advancedSearch", placeId);
startActivity(i);
} else {
Toast.makeText(context, "Please select an item from the autocomplete list", Toast.LENGTH_SHORT).show();
}
}
});
}
public void onItemClick(AdapterView<?> adapterView, View view,
int position, long id) {

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:

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);
}
