Question

I am trying to make an application as a school project and I MUST implement Google Maps. I am fairly new to Android coding and now little of Java. So far I created this application using Google Maps API v2, I obtained a key, I added all the permissions and code in the manifest, I added the default Google example code to make a map simply appear but I get a crash and lots of errors when running the application. I also added existing code and set it to project library, I set target and compile with to be specifically with the API’s. I keep “banging my head” trying to get this to work. I saw other questions have similar problems but resolved with something I already have completed.
Since I’m having troubles adding code by text, I hope you guys can understand I used exactly what Google posted as their tutorial. I can’t do images due to my rep.

I managed to fix this thanks to newbostonforums and I am adding my findings for anyone else seeking help. You need to add google-play-services_lib to your project.

Right click IMPORT
Android->Existing Code->(SDK/extras/google/google_play_services/libproject/google-play-services_lib)

Right click on project. Properties->Android->Library-ADD->(SDK/extras/google/google_play_services/libproject/google-play-services_lib

Once you added the folder it will be “linked” with the project.

In JAVA you must add

MAKE SURE YOU IMPORT ALL RED UNDERLINED.

public class Main extends FragmentActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    SupportMapFragment fragment = new SupportMapFragment();
    getSupportFragmentManager().beginTransaction()
            .add(android.R.id.content, fragment).commit();

Then your XML can be at your choosing but it must include

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:name="com.google.android.gms.maps.SupportMapFragment"
// POSSIBLY OPTIONAL
android:id="@+id/map"

You may replace android:name with class but I don’t know the difference. I believe they both work.

However there are many ways to make it work and I am somewhat changing this method.
