App with Google Map crashes when I extend FragmentActivity

I know this question has been asked many times here, but none of the solutions provided stopped my app from crashing.
Here is my code from the MainActivity:
package com.example.gpstracking2;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.app.Dialog;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GooglePlayServicesUtil;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.Marker;
public class MainActivity extends FragmentActivity {
GoogleMap googleMap;
Marker marker = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_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;
}
}
Here is the code from the activity_main.xml from the layout folder:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

</LinearLayout>
Here is the manifest file:

Does your activity extend android.app.activity ? Is the activity mentioned in the manifest file. Is the base package and fully qualified name of the activity class correct??

Starting with Android Google Maps API V2

I am newbie on Android Google Maps API and I was trying to develop a small app using the API. I use as a reference the Google documentation form: https://developers.google.com/maps/documentation/android/ and I follow all the step with caution. When I build it and install it on to my device (Android 2.3.6) the app crash. I follow all the instructions to sign the app and get the API key for this specific app, tried all the step of the documentation several times without any good results. Please, can someone help me with this? I there something missing?
Thank you!

First thing as you are having the API level 8 or below so you have to use the SupportMapFragment instead of MapFragment as below in your layout 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"/>
Second thing you have to extend the FragmentActivity instead of Activity :
public class MainActivity extends FragmentActivity {
Do the above changes and then run your application.

Google Maps Android API v2 and Eclipse

I am new in Google Map and so many things aren't clear enough to me for that reason.So i expect some expert's direction on this regard.I read This Guide and did everything what it says.I use google map api v2 and get a map key.Then i make a sample project following that link and select target version android 2.2(while running the project).But a list of error occurs after running then example in eclipse android emulator.My logcat view shows:

Sorry for this lengthy description,but i want to show you exactly what i did.I think as a newcomer i did a lot of mistake on this way.so i expect someone will guide me that.

You are using features only available in later APIs, namely Fragment. If you want to compile to support 2.2, you need to include the Support Library in your project. You will also have to make the following changes to use support fragments instead of regular fragments --
In main.xml, change
class="com.google.android.gms.maps.MapFragment"/>
to
class="com.google.android.gms.maps.SupportMapFragment"/>
and in your activity.java, change
public class LocationProfileManagerActivity extends Activity {
to
public class LocationProfileManagerActivity extends FragmentActivity {

you need to make two changes
Since as you are sdk version is below 12, need to make following change
1)
main.xml
Replace
class="com.google.android.gms.maps.MapFragment"/>
with
class="com.google.android.gms.maps.SupportMapFragment"/>
2) activity.java
Need to extend FragmentActivity instead of Activity
If you want to test in emulator , then download the google_play_services_apk and install it in emulator.

Maps API v2 cannot be run in an emulator because of its dependency on Google Play Services, which is bundled in the Google Play Store .apk. It can be hacked together though, you can read about it here on the first Google result for "Google maps v2 emulator". Also you can still use V1 for a limited time, you can get started here.

java.lang.ClassNotFoundException on my android app but I have no idea why

I've been trying to get started with Android programming for a while now. I'm mainly a .NET developer with no Java experience for 8 years (university).
I can compile and run samples no problem but the moment I try and rename my package/class it fails. I believe I've updated the manifest and triple checked it (Copied and pasted name, selected it with Eclipse) yet it always fails with a java.lang.ClassNotFoundException:

public class HelloAndEngine extends BaseGameActivity
This sample is from AndEngine but I've had the same issue with every sample I modify. I can't help but feel I've missed something and nothing I found searching has helped.
Any advice appreciated!

Try this.
<activity android:label="#string/app_name" android:name=".HelloAndEngine">
You don't need the fully qualified class name. Also, if you are working with Eclipse and rename a package go to Project → Clean and let it clean up your project, fixing up references and so on if anything is broken.

This is a bug in eclipse android tools
http://code.google.com/p/android/issues/detail?id=2824
To Fix -> Right click on the project go to Android tools -> Rename application package..
And also check AndroidManifest.xml if it updated correctly, in my case it didn't, that should solve this problem
