I have been researching everywhere and haven't found a concrete example of how to do this. I want to know how to send a HTTP request to Google to bring back data on places around my current location which is stored in LatLng? and then parse that data in JSON to then display on my map. Im new to android development so apologies if this question seems silly. I have looked through the Google documentation on this but I cant get my head around it :(
My MainActivity.Java file:
package com.example.mapapp;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationManager;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.GoogleMap.OnMyLocationChangeListener;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.LatLng;
public class MainActivity extends FragmentActivity implements OnMyLocationChangeListener {
GoogleMap map;
LatLng myPosition;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
map.setMyLocationEnabled(true);
LocationManager locationmanager = (LocationManager) getSystemService(LOCATION_SERVICE);
Criteria criteria = new Criteria();
String provider = locationmanager.getBestProvider(criteria, true);
Location location = locationmanager.getLastKnownLocation(provider);
if(location!=null){
double latitude = location.getLatitude();
double longitude = location.getLongitude();
myPosition = new LatLng(latitude, longitude);
}
}
#Override
public void onMyLocationChange(Location location) {
// TODO Auto-generated method stub

If you want to show places nearby, you need to use Google Places API.
You can read this tutorial about how to setup API project in your Google Developer Console.
Also, you can read this series of tutorials about how to to show places nearby.

EDIT: Man this is awkward, MKer is right, I corrected the code and now can see the ScaleBar. No luck yet with the my location issue.
I have been trying for a few days and I'm starting to pull my hair. Noob at Android and Osmdroid.
I can build and have done so, with success, osmdroid demo apps. Also tried the OSMbonuspack and had the navigator working with the "find me" overlay, scale, etc.
Problem is whenever I make my own app, the only overlay that shows up and works in my map is the compass. I guess I am doing something wrong but can't find any info on the subject.
I have tested this with Genymotion virtual devices (there not even the compass shows) amd my 6.0 mobile where compass works, but no MyLocation or even Scale.
I have given the app permissions, and all I see in the android log are messages about tiles loading when moving the map. Plus this error which I haven't found much info about except in chinese.
E/IzatSvc_PassiveLocListener: E/Exiting with error virtual void izat_manager::IzatPassiveLocationListener::onLocationChanged(const izat_manager::IzatLocation*, izat_manager::IzatLocationStatus) line 113 "1"
Any help welcome!

I am developing a game in libgdx. I read the official docs and tried to integrate MobClix Ads in my App but eclipse can't resolve this constructor for ADView class: (for Example):
AdView ad = new AdView(this, AdSize.BANNER, "a14d91b10f12454");
This line of code give me an error.
Maybe my import is not correct? I import this:
import com.google.android.gms.ads.AdSize;
import com.google.android.gms.ads.AdView;
And the same for:
adView.loadAd(new AdRequest());
I tried to search for an answer but I coudn't find, Does somone know how to resolve this?
Sorry for my poor english.
Put this code to mainactivity
import android.app.Activity;
import android.os.Bundle;
import com.startapp.android.publish.StartAppAd;
public class MainActivity extends Activity {
private StartAppAd add = new StartAppAd(this);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
StartAppAd.init(this, "105158220", "205151606");
//StartAppSearch.init(this, "105158220", "205151606");
setContentView(R.layout.activity_main);
if(add.isReady())
{
add.showAd(); // show the ad
add.loadAd();
}
//a.loadAd(AdMode.FULLPAGE);
}
#Override

super.onResume();
add.onResume();
}
#Override

add.onBackPressed();
super.onBackPressed();

You can only view it in a phone.
What you see now is all you can get in the Emulator.
You're not asking for any of the gps permissions.
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
Also since you're using fake locations, you might want to include this one as well. I don't know if it's relevant in this case, but just in case.
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION"/>
Also, I know you said you're currently testing on a device, but for anyone who's curious about running google maps on an emulator (with the new Google Play dependency), it can be done this way.
Did you generate the API-Key with your debug-keystore or do you sign the application with a another keystore to build for the device? The API-Key is bind to a keystore and must be changed if you sign with another keystore or another debug-keystore on another developer-machine.
seems the guy who wrote about the permissions was right,
but I had the same problem and the solution was to correct the package name in the
internet site of google where you get the api key.
because I built at the same day another project with almost the same package name,
and forgot I produced the api key with that project,it didn't work for me with the second project.
I created fragment in .xml file:
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
and I also init. GoogleMap and fragment objects in .java file:
private GoogleMap maps;
private View fragment1;
fragment1 = findViewById(R.id.map);
but When I was trying to create GoogleMap object
maps = ((MapFragment) getFragmentManager().findFragmentById(
R.id.map)).getMap();
I'm getting an error on getFragmentManager() eclipse couldn't find this method
How can I overcome this issue?
Make sure that your class extends FragmentActivity and your android project is google api project.
in Xml File
<?xml version="1.0" encoding="utf-8"?>
<fragment
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.SupportMapFragment"/>
and in Java File
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mMap = fm.getMap();
follow this tutorial
Google Map Using Fragment
in your manifest file
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<application>
...
<meta-data android:name="com.google.android.maps.v2.API_KEY"
android:value="HERE GOES YOUR API KEY" />
</application>
pls import the class , "import android.support.v4.app.FragmentActivity " Class in your main activity.
it can be imported if u have the google play service downloaded.
Check your manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.
android:versionCode="1"
android:versionName="1.0" >

<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

</manifest>
Check your layout file:
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
Check your source file:
GoogleMap googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
no need to extend FragmentActivity
try below code:
public class MainActivity extends Activity {
private GoogleMap googleMap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Loading map
initilizeMap();
}
#Override
protected void onResume() {
super.onResume();
initilizeMap();
}
private void initilizeMap() {
if (googleMap == null) {
googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
if (googleMap == null) {
Toast.makeText(getApplicationContext(), "Sorry! unable to create maps",
Toast.LENGTH_SHORT).show();
}
}
}
}
