The app is stopped when load the map

Question

Hi I want the map inside my app... I copy three tutorial and I change key for every project and the result is " the app is stopped" I use Frangment or SupportFrangment.... Why my Samsung S4 not execute the app for see map?

Now I explain my app where I copy and change from this tutorial Premise: I load google-play-service for two times: 1- File->Import->Existing project into workspace-> google-play-services and include in every project

2-Add library google-play-services in properties of project.

Where I wrong ?? This is the manifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.com.vogella.android.locationapi.maps"

            android:value="KeyVALUE API" />
    </application>

</manifest>

This is a frangment.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"

    <fragment

        android:layout_height="match_parent"
        class="com.google.android.gms.maps.MapFragment" />

</RelativeLayout>

This is a ShowMapActivity.java:

    package com.example.com.vogella.android.locationapi.maps;

import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;

public class ShowMapActivity extends Activity {
  static final LatLng HAMBURG = new LatLng(53.558, 9.927);
  static final LatLng KIEL = new LatLng(53.551, 9.993);
  private GoogleMap map;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_show_map);
    map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
        .getMap();
    Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG)
        .title("Hamburg"));
    Marker kiel = map.addMarker(new MarkerOptions()
        .position(KIEL)
        .title("Kiel")
        .snippet("Kiel is cool")
        .icon(BitmapDescriptorFactory
            .fromResource(R.drawable.ic_launcher)));

    // Move the camera instantly to hamburg with a zoom of 15.
    map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));

    // Zoom in, animating the camera.
    map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
  }

  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.show_map, menu);
    return true;
  }

}

This is the LogCat:

The error you get now is very different than the first one. As @panini says, it looks like you left something out, though. We need the rest of the stack trace in order to help you. — Code-Apprentice, Jun 24 '14 at 01:22

Is this Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG) — Mirko Cianfarani, Jun 24 '14 at 01:29
The error is exactly on map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap(); — Mirko Cianfarani, Jun 24 '14 at 01:35

In your AndroidManifest you have said that you will provide a class named MainActivity, however you have renamed this to ShowMapActivity, meaning that the system can't find the activity it is supposed to use

You need to use the newer map which is the SupportMapFragment instead of MapFragment, and use the name identifier to find the class of the SupportMapFragment.

sample:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ShowMapActivity" >

<fragment
    android:id="@+id/map"
    android:name="com.androidmapsextensions.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

</RelativeLayout>

Also you need to change the casting of map to SupportMapFragment.

SupportMapFragment map;

map = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map))
    .getMap();

The app is stopped when load the map
