Why does this line of code crash my app

I have seen many other questions like this one on this website and tried changing my code to match but it never solves the problem.
My app loads with some buttons to push. One of them opens a class file that opens a map on the screen. The code for that class is :
public class FuelMap extends Activity
{
private final LatLng locBurb = new LatLng(49.27645, -122.917587);
private final LatLng locSura = new LatLng(49.187500, -122.849000);
private GoogleMap map;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fuel_map);
//map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map )).getMap();
// Show the Up button in the action bar.
setupActionBar();
}
/**
* Set up the {#link android.app.ActionBar}, if the API is available.
*/
#TargetApi(Build.VERSION_CODES.HONEYCOMB)
private void setupActionBar()
{
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)
{
getActionBar().setDisplayHomeAsUpEnabled(true);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.fuel_map, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId()) {
case android.R.id.home:
// This ID represents the Home or Up button. In the case of this
// activity, the Up button is shown. Use NavUtils to allow users
// to navigate up one level in the application structure. For
// more details, see the Navigation pattern on Android Design:
//
// http://developer.android.com/design/patterns/navigation.html#up-vs-back
//
NavUtils.navigateUpFromSameTask(this);
return true;
}
return super.onOptionsItemSelected(item);
}
public void OnClickCity(View C)
{
//CameraUpdate update = CameraUpdateFactory.newLatLng(locBurb);
//map.animateCamera(update);
}
public void OnClickBuraby(View B)
{
}
public void OnClickSurray(View S)
{
}
}
But if I uncomment the line: //map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map )).getMap();
and then the app will run until i try to switch it over to the map.
Like I said at the beginning of this I have searched and often found answers on this site relating to my question but none of them gave me any results. I do not believe this problem is due an error of installing the google map stuff needed for the android app since I can load a map. So anyone know what might be the cause?

try this link: in google maps V2 ... fragment.getMap() returns null
it appears that the map fragment you are trying to load hasn't been instantiated yet, in the onCreateView().
Hopefully this solves the issue. You might need to post to a handler after the map loads.. essentially a callback.

I t seems that you are using Maps V2 so your declaration in the xml is not right.
It is a fragment not a FragmentLayout as mention in the Android Developer
<?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.MapFragment"/>

Thanks a ton for all the help guys. I final figured out the problem. It was the letter 's'.
In this line: //map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map )).getMap(); I was was pulling the object called map. If you look in my activity_Fuel_Map layout the map object is a TextView.
` <TextView
android:id="#+id/map"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/maps"
android:layout_alignParentTop="true"
android:layout_marginLeft="33dp"
android:ems="10"
android:text="Map" >`
So I had to change the (R.id.map) to (R.id.maps) to pull my map fragment.
<fragment
android:id="#+id/maps"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/busCity" />
Thanks again for all the help guys.

You are missing a meta tag in the manifest file
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
You don't need these
<permission
android:name="com.geo.app.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
Also it is better to check the availability of google play services before intializing GoogleMap object
Edit:
java.lang.NoClassDefFoundError: com.google.android.gms.R$styleable
You haven't referenced google play services library project in your android map project.

In your MainActivity.java class change the fragment import statement
import android.support.v4.app.Fragment

SupportMapFragment not found

I am trying to get Google Maps Android API v2 working on Android 2.2 on a HTC Desire.
My main.xml contains the following:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="dk.sw510e13.user"

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
This is my activity.
package dk.sw510e13.user;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
public class MainActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
When I run the application, I will get the following exception. It seems that it cannot find SupportMapFragment, however, I believe that I have both the support library and Google Play Services as dependencies. When creating the project in Android Studio I chose to add support for fragments.

This is the problem that seems to be occurred when missing Google Play services.
I request you to please follow the steps mentioned below to get the Google Play services to be included in your application.
copying the google-play-services.jar in libs folder and set in the build path of eclipse is a wrong method.
import Google Play services in your project and add it in workspace.
from location of your SDK folder.
\extras\google\google_play_services\libproject\google-play-services_lib
2! Now you added Google Play Services to your work space, we have to create a reference
from our project to this library. Right-Click your project and choose “Properties” go
to the Android section, in the lower part press the “Add…” button and add a reference
to that library. Your result should be as in the screen shot bellow:
adding Google Play services library
Please Add
<permission
android:name="com.anchit.locationapi.maps.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
in your manifest

Google Play Service library and Google Maps

I try to create a simple GoogleMap by Using Google Play Service and Google Maps API. But all the times I get errors...

I think the Problem is how I include the GooGlePlayService... I´ve tried to add as module, as libary as External Libary but I don't know how to include and to use it right... :(

****EDIT2**
Problem solved by using this: java.lang.noclassdeffounderror: com.google.android.gms.R$styleable**

The only thing I find missing in your RecorderMap.java file is that you haven't imported the SupportFragment class. So add this line to it
import com.google.android.gms.maps.SupportMapFragment;
If that doesn't work, then check out the following.
From what you are saying, it means you have already installed the google play services. If not, then try installing it using this link http://developer.android.com/google/play-services/setup.html
After that, referencing the google play services library should be as easy as editing your build.gradle file. The current version of android studio makes this possible. Under dependencies in your build.gradle file, add the following code
compile 'com.google.android.gms:play-services:3.1.36'
You seem to have your API key intact.
Finally, remember you need to test your app on an actual android device and not an emulator. The android API version 2 is not yet able to display maps on emulators.
I think this should be okay for your app to work.

Google Maps API v2 - I could not display the Map in my app

I'm new to Google Maps API and I'm trying to display a map in my application. Every try has failed, I don't understand why.

Have you got any idea to solve this problem?
P.S. sorry for my bad english...

Because You writing your application targeting SDK 9, and you use SupportMapFragment (as you should) in your XML file. Then you have to use getSupportFragmentManager and SupportMapFragment method.
Like that:
map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
instead of this:
mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

It looks like it isn't able to find the maps API. Have you downloaded and configured the Google Play services SDK: https://developers.google.com/maps/documentation/android/start#the_google_maps_api_key
?

Use getSupportFragmentManager() instead of getFragmentManager(). The latter is only defined since Honecomb (and your minsdk is GingerBread) while the former is defined in the support library (that I see you are using since you extend FragmentActivity).
That's why you had to add #TargetApi and #SupressLint... ADT was warning you and you silenced it... =) You should remove those.

In xml file use android:name="com.google.android.gms.maps.SupportMapFragment" instead of
class="com.google.android.gms.maps.SupportMapFragment"
Let me know it`s working
