I am making an app in which i have a navigation screen where the user can give in multiple locations.
Those locations are stored in a array string.
I am using that string in my map class and i want to show al the locations on the map with a marker.
Only the last location stored in the array shows up.
Can anybody help me please.

a few hints:
On FindLocation add an else to catch not found locations:
public void FindLocation(String plaats) {

try {
List<Address> addresses = geoCoder.getFromLocationName(
plaats, 5);
//String add = "";

counter++;
coordinates[counter] = (int) (addresses.get(0).getLongitude() * 1E6);
counter++;
} else {
Log.v(TAG, "Site " + plaats + " not found!");
}
} catch (IOException e) {
e.printStackTrace();
}
}
Also in onCreate() loop over already defined locations, not the whole array:
for (int i = 0; i<count; i+=2)
{
point = new GeoPoint(coordinates[i], coordinates[i+1]);
OverlayItem overlayItem = new OverlayItem(point, "new place added", null);
itemizedOverlay.addOverlayItem(overlayItem);
}

Hi I have developed an android app which uses google places api to display the nearby locations.
Now when I click on a place name I want to display its location in the map. My question is that how to pass the latitude and longitude to the google maps to be displayed. Right now I am passing the values statically but when I click on the name I want to pass its lat and long dynamically to be drawn. Please tell me how to do that. I am new to android.

Not Executing - What should we consider this as a Compile Time or a Runtime Error.
If yes paste the error logs. Also
Are You Trying this on Real Device ? If not do so
Is GPS of your device is ON ? if not do so
Try using 0 parameter instead of 200. See its results.
Also try LocationManager.NETWORK_PROVIDER
Make Sure You have sufficient permission defined in Manifest File.
I have this textbox in the other activity and a button which leads to this map. What i want to do is that it allows the user to click the map and pin point the location they wants, and they can also fetch that location's address back to the textbox without typing. Can it be done so? Since now there is this alert dialog box which pop up after user pin point it with 2 buttons(Yes and No) So if yes, fetch that location address back to the textbox. Any idea?

Well you can try reverse geocoding. What that needs is you to supply the lat long of the point that the user tapped on, which is fairly easy.
Check this similar question. might help.
