Android - Google MAP V2 PART 2



Before do this check part 1

Note : I have to run this in API 8 to API 17 that why i have used ActionBarSherlock support library. if you don't want that then replace it. 
In main Activity i have added following code.

 package com.djandroid.mapsv2;  
 import android.os.Bundle;  
 import android.support.v4.app.FragmentManager;  
 import com.actionbarsherlock.app.SherlockFragmentActivity;  
 import com.google.android.gms.maps.GoogleMap;  
 import com.google.android.gms.maps.GoogleMap.OnMapClickListener;  
 import com.google.android.gms.maps.SupportMapFragment;  
 import com.google.android.gms.maps.model.LatLng;  
 import com.google.android.gms.maps.model.MarkerOptions;  
 public class MainActivity extends SherlockFragmentActivity {  
      private GoogleMap MAP;  
      @Override  
      protected void onCreate(Bundle arg0) {  
           // TODO Auto-generated method stub  
           setTheme(R.style.Theme_Sherlock);  
           super.onCreate(arg0);  
           setContentView(R.layout.activity_main);  
           FragmentManager myFM = getSupportFragmentManager();  
           SupportMapFragment myMAPF = (SupportMapFragment) myFM  
                     .findFragmentById(R.id.fragment1);  
           MAP = myMAPF.getMap();  
           MAP.setMyLocationEnabled(true);  
           MAP.setMapType(GoogleMap.MAP_TYPE_HYBRID);  
           MAP.setOnMapClickListener(new OnMapClickListener() {  
                @Override  
                public void onMapClick(LatLng point) {  
                     // TODO Auto-generated method stub  
                     MAP.addMarker(new MarkerOptions().position(point).title(  
                               point.toString()));  
                }  
           });  
      }  
 }

Without ActionBarsharelock:


 

 package com.djandroid.mapsv2;  
 import android.os.Bundle;  
 import android.support.v4.app.FragmentActivity;  
 import android.support.v4.app.FragmentManager;  
 import com.google.android.gms.maps.GoogleMap;  
 import com.google.android.gms.maps.GoogleMap.OnMapClickListener;  
 import com.google.android.gms.maps.GoogleMap.OnMarkerClickListener;  
 import com.google.android.gms.maps.SupportMapFragment;  
 import com.google.android.gms.maps.model.LatLng;  
 import com.google.android.gms.maps.model.Marker;  
 import com.google.android.gms.maps.model.MarkerOptions;  
 public class MainActivity extends FragmentActivity {  
      private GoogleMap MAP;  
      @Override  
      protected void onCreate(Bundle arg0) {  
           // TODO Auto-generated method stub  
           // setTheme(R.style.Theme_Sherlock);  
           super.onCreate(arg0);  
           setContentView(R.layout.activity_main);  
           FragmentManager myFM = getSupportFragmentManager();  
           SupportMapFragment myMAPF = (SupportMapFragment) myFM  
                     .findFragmentById(R.id.fragment1);  
           MAP = myMAPF.getMap();  
           MAP.setMyLocationEnabled(true);  
           MAP.setMapType(GoogleMap.MAP_TYPE_HYBRID);  
           MAP.setOnMapClickListener(new OnMapClickListener() {  
                @Override  
                public void onMapClick(LatLng point) {  
                     // TODO Auto-generated method stub  
                     MAP.addMarker(new MarkerOptions().position(point).title(  
                               point.toString()));  
                }  
           });  
      }  
 }

You have to test the application on a real device as the emulator is not supported.
Enjoy....

Related Errors:

If we not add this in manifest:


 <uses-feature  
     android:glEsVersion="0x00020000"  
     android:required="true" />


Then error is : java.lang.RuntimeException: Google Maps Android API only supports OpenGL ES 2.0 andabove. Please add <uses-feature android:glEsVersion="0x00020000" android:required="true" /> into AndroidManifest.xml

 
 <meta-data  
       android:name="com.google.android.maps.v2.API_KEY"  
       android:value="API_KEY" />

then error is : java.lang.RuntimeException: API key not found.  Check that <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="your API key"/> is in the <application> element of AndroidManifest.xml

      in your fargment you have write: supportmapfragment then in your activity you have to use supportmapfragment

      or

      if you have use mapfragment then you have to use mapfragment in activity

      i think this is your issue otherwise send me your code..

      As a note, if you use Android support library to display a map, please make sure that your layout xml file that contains the map fragment should have an android:name attribute value to com.google.android.gms.maps.SupportMapFragment

      or if you are not using Android support library then use com.google.android.gms.maps.MapFragment

Connecting mysql Database in ANDROID using PHP & JSON

 To implement this tutorial you should have basic knowledge of how to run PHP script and start server.  If we talk about client-server architecture, client is Android device and in server side there is a combination of PHP Script and MySQL. In short, PHP Script sits in middle as shown in image. Lets suppose that we have a MySQL database named Employee, and a table int created, with the following SQL: CREATE TABLE `employee` (   `emp_id` int(11) NOT NULL auto_increment,   `emp_name` varchar(100) NOT NULL,   PRIMARY KEY  (`emp_id`) ) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=5 ; The PHP code will be very simple: Now Create Android Project :  The Android part is only a bit more complicated: -use a HttpPost to get the data -convert response to string -parse JSON data in to List In Your First Activity : O/P :
