Solution 1 - Android

public GeoPoint getLocationFromAddress(String strAddress) {

    Geocoder coder = new Geocoder(this);
    List<Address> address;
    GeoPoint p1 = null;

    try {
        address = coder.getFromLocationName(strAddress, 5);
        if (address == null) {
            return null;
        }
        Address location = address.get(0);
        location.getLatitude();
        location.getLongitude();

        p1 = new GeoPoint((double) (location.getLatitude() * 1E6),
                (double) (location.getLongitude() * 1E6));

        return p1;
    } catch (IOException e) {
        e.printStackTrace();
    }
    return null;
}

strAddress is a string containing the address. The address variable holds the converted addresses.

Ud_an's solution with updated API's

Note: LatLng class is part of Google Play Services.

Mandatory:

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
  
<uses-permission android:name="android.permission.INTERNET"/>

Update: If you have target SDK 23 and above, make sure you take care of runtime permission for location.

public LatLng getLocationFromAddress(Context context,String strAddress) {

	Geocoder coder = new Geocoder(context);
	List<Address> address;
	LatLng p1 = null;

	try {
        // May throw an IOException
		address = coder.getFromLocationName(strAddress, 5);
		if (address == null) {
			return null;
		}

		Address location = address.get(0);
		p1 = new LatLng(location.getLatitude(), location.getLongitude() );

	} catch (IOException ex) {

		ex.printStackTrace();
	}

	return p1;
}

If you want to place your address in google map then easy way to use following

Intent searchAddress = new  Intent(Intent.ACTION_VIEW,Uri.parse("geo:0,0?q="+address));
startActivity(searchAddress);

if you needed to get lat long from your address then use Google Place Api following

create a method that returns a JSONObject with the response of the HTTP Call like following

public static JSONObject getLocationInfo(String address) {
		StringBuilder stringBuilder = new StringBuilder();
		try {
		
		address = address.replaceAll(" ","%20");	
		
		HttpPost httppost = new HttpPost("http://maps.google.com/maps/api/geocode/json?address=" + address + "&sensor=false");
		HttpClient client = new DefaultHttpClient();
		HttpResponse response;
		stringBuilder = new StringBuilder();

		
			response = client.execute(httppost);
			HttpEntity entity = response.getEntity();
			InputStream stream = entity.getContent();
			int b;
			while ((b = stream.read()) != -1) {
				stringBuilder.append((char) b);
			}
		} catch (ClientProtocolException e) {
		} catch (IOException e) {
		}

		JSONObject jsonObject = new JSONObject();
		try {
			jsonObject = new JSONObject(stringBuilder.toString());
		} catch (JSONException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

		return jsonObject;
	}

now pass that JSONObject to getLatLong() method like following

public static boolean getLatLong(JSONObject jsonObject) {

		try {

			longitute = ((JSONArray)jsonObject.get("results")).getJSONObject(0)
				.getJSONObject("geometry").getJSONObject("location")
				.getDouble("lng");

			latitude = ((JSONArray)jsonObject.get("results")).getJSONObject(0)
				.getJSONObject("geometry").getJSONObject("location")
				.getDouble("lat");

		} catch (JSONException e) {
			return false;
			
		}

		return true;
	}

I hope this helps to you nd others..!! Thank you..!!

The following code will work for google apiv2:

public void convertAddress() {
    if (address != null && !address.isEmpty()) {
        try {
            List<Address> addressList = geoCoder.getFromLocationName(address, 1);
            if (addressList != null && addressList.size() > 0) {
                double lat = addressList.get(0).getLatitude();
                double lng = addressList.get(0).getLongitude();
            }
        } catch (Exception e) {
            e.printStackTrace();
        } // end catch
    } // end if
} // end convertAddress

Where address is the String (123 Testing Rd City State zip) you want to convert to LatLng.

Solution 5 - Android

This is how you can find the latitude and longitude of where we have click on map.

public boolean onTouchEvent(MotionEvent event, MapView mapView) 
{   
    //---when user lifts his finger---
    if (event.getAction() == 1) 
    {                
        GeoPoint p = mapView.getProjection().fromPixels(
            (int) event.getX(),
            (int) event.getY());

        Toast.makeText(getBaseContext(), 
             p.getLatitudeE6() / 1E6 + "," + 
             p.getLongitudeE6() /1E6 , 
             Toast.LENGTH_SHORT).show();
    }                            
    return false;
}

it works well.

To get the location's address we can use geocoder class.

An answer to Kandha problem above :

> It throws the "java.io.IOException service not available" > i already gave those permission and include the library...i can get map view...it throws that IOException at geocoder...

I just added a catch IOException after the try and it solved the problem

    catch(IOException ioEx){
        return null;
    }

Solution 7 - Android

public void goToLocationFromAddress(String strAddress) {
    //Create coder with Activity context - this
    Geocoder coder = new Geocoder(this);
    List<Address> address;

    try {
        //Get latLng from String
        address = coder.getFromLocationName(strAddress, 5);

        //check for null
        if (address != null) {

            //Lets take first possibility from the all possibilities.
            try {
                Address location = address.get(0);
                LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());

                //Animate and Zoon on that map location
                mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
                mMap.animateCamera(CameraUpdateFactory.zoomTo(15));
            } catch (IndexOutOfBoundsException er) {
                Toast.makeText(this, "Location isn't available", Toast.LENGTH_SHORT).show();
            }

        }


    } catch (IOException e) {
        e.printStackTrace();
    }
}

Solution 8 - Android

Geocoder coder = new Geocoder(this);
        List<Address> addresses;
        try {
            addresses = coder.getFromLocationName(address, 5);
            if (addresses == null) {
            }
            Address location = addresses.get(0);
            double lat = location.getLatitude();
            double lng = location.getLongitude();
            Log.i("Lat",""+lat);
            Log.i("Lng",""+lng);
            LatLng latLng = new LatLng(lat,lng);
            MarkerOptions markerOptions = new MarkerOptions();
            markerOptions.position(latLng);
            googleMap.addMarker(markerOptions);
            googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(latLng,12));
        } catch (IOException e) {
            e.printStackTrace();
        }

Solution 9 - Android

public LatLang getLatLangFromAddress(String strAddress){
    Geocoder coder = new Geocoder(this, Locale.getDefault());
    List<Address> address;
    try {
        address = coder.getFromLocationName(strAddress,5);
        if (address == null) {
                return new LatLang(-10000, -10000);
            }
            Address location = address.get(0);
            return new LatLang(location.getLatitude(), location.getLongitude());
        } catch (IOException e) {
            return new LatLang(-10000, -10000);
        }
    }

LatLang is a pojo class in this case.

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> permission is not required.

I know I am too late for the contribution of 10 years old question, in the year 2021. The following code is fully complete working code.

code for activity_main.xml:-

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
