import android.view.MenuItem;
import android.widget.Toast;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.NavUtils;



public class MainActivity extends FragmentActivity {

     private GoogleMap googleMap;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        try {
            // Loading map
            initilizeMap();

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

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        return true;
    }

    private void initilizeMap() {
        if (googleMap == null) {

            //googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

            googleMap =   ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

            // check if map is created successfully or not
            if (googleMap == null) {
                Toast.makeText(getApplicationContext(),
                        "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                        .show();
            }
        }
    }

Change

public class MainActivity extends FragmentActivity {

to

public class MainActivity extends Activity {

Change this

googleMap =   ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

to

googleMap =   ((MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();

You also need the below in application tag in manifest

<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />

which is a requirement of google play services rev 13

Edit:

Move

 <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="AIzaSyBYju6h2BWvZOaSDQpe5f9tv6fJsZy6cY8" />

inside application tag in manifest

thank you. i done but still crashesh. app come up for while but it crashesh :( – Mahdi Nov 25 '13 at 12:40
@mahdit you need to post the stacktrace for further help – Raghunandan Nov 25 '13 at 12:41
how i can send you stacktraces? – Mahdi Nov 25 '13 at 12:45
@mahdit extract the lines that show the exception in logcat and post it here. – Raghunandan Nov 25 '13 at 12:46
i put Log.e("LOG", "I got an error", e); on catch of initilizeMap() try section. but nothings loged with LOG filter. – Mahdi Nov 25 '13 at 12:49
@mahdit you will see a caused by part in your logcat which indicates the cause of exception. post it here. – Raghunandan Nov 25 '13 at 12:51
@mahdit remove all the imports from support library and make the changes suggested in my post clean and build project. You need to use `MapFragment` extend `Activity` – Raghunandan Nov 25 '13 at 12:57
@mahdit check line 25 `MainActivity.java`. What is it? – Raghunandan Nov 25 '13 at 13:01
it's refer on setContentView(R.layout.activity_main); that in MainActivity. – Mahdi Nov 25 '13 at 13:03
@mahdit did you change `googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();`?? and did you extend `Activity`. Also move the meta tag inside application in manifest – Raghunandan Nov 25 '13 at 13:05
thanks, the crash was gone with your two tips. but app said that i must upgrade my google play service on Glaxy s 3. so what i can do to run the app even on older androids when it's wont even run on my 4.0.1 phone :( – Mahdi Nov 25 '13 at 13:15
@mahdit update google play services. google maps api is part of google play services so you will need it to show maps. also for api level 11 and below you will need to use `SupportMapFramgent` and extend FragmentActivtiy. In your manifest its 16 so no need to worry – Raghunandan Nov 25 '13 at 13:18
ok. i appreciation :). and one more question. how did you find out the problem from line25? – Mahdi Nov 25 '13 at 13:28
@Kenji usually the logcat indicates the caused by part and the line that causes the exception. you can look at it and find out the problem – Raghunandan Nov 25 '13 at 14:29
@Raghunadan i'm tring to use this app on skd 8 but app crashesh and make me crazy! what is should do? – Mahdi Dec 10 '13 at 06:44
@Kenji you need to use `SupportMapFragment`. Activity Need's to extend `FragmentActivty`. Should us Support library fro backward compatibility. With all this in place should work without a fuss. – Raghunandan Dec 10 '13 at 07:26

Try with this.

Your MainActivity

private void initilizeMap() {
    if (googleMap == null) {
        googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
        // Valida si el mapa no se creo correctamente
        if (googleMap == null) {
            Toast.makeText(getApplicationContext(), "Sorry! el mapa no pudo ser cargado", Toast.LENGTH_SHORT)
                    .show();
        }
    }
}

In your layout this

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<fragment
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.SupportMapFragment" />

In the manifest, i used this lines in MAC, because in Windows works correctly works without them

<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />

my problem is solved and i think it was because of dont let metadata inside of tag. thanks for noticing ;) — Mahdi, Nov 25 '13 at 13:32

I had a similar problemt. For me adding:

import com.google.android.gms.maps.SupportMapFragment;

And changing the xml to

    <fragment
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/header"  />

resolved the problem. I hope you resolve it too!
