I tried to merge two android demo programs, but I couldn't get it right.

I have tried and searched for several ways, but I couldn't figure it out. Could you please help me?

Here's my error message:

Here's my source code, I only changed this function:

private void selectItem(int position) {
    // update the main content by replacing fragments

    Fragment mapfragment = new BasicMapActivity();

    Fragment fragment = new PlanetFragment();
    Bundle args = new Bundle();
    args.putInt(PlanetFragment.ARG_PLANET_NUMBER, position);
    fragment.setArguments(args);

    mapfragment.getFragmentManager();
    FragmentManager fragmentManager = getSupportFragmentManager();
    fragmentManager.beginTransaction().replace(R.id.content_frame, mapfragment).commit();

    // update selected item and title, then close the drawer
    mDrawerList.setItemChecked(position, true);
    setTitle(mPlanetTitles[position]);
    mDrawerLayout.closeDrawer(mDrawerList);
}

Here's my map fragment:

public class BasicMapActivity extends Fragment {
/**
 * Note that this may be null if the Google Play services APK is not available.
 */
private GoogleMap mMap;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //setUpMapIfNeeded();
    //setContentView(R.layout.basic_demo);

}
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    //setUpMapIfNeeded();
     View rootView = inflater.inflate(R.layout.basic_demo, container, false);
     setUpMapIfNeeded();
     return rootView;
}

@Override
public void onResume() {
    super.onResume();
    setUpMapIfNeeded();
}

private void setUpMapIfNeeded() {
    // Do a null check to confirm that we have not already instantiated the map.
    if (mMap == null) {
        // Try to obtain the map from the SupportMapFragment.
        mMap = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
        // Check if we were successful in obtaining the map.
        if (mMap != null) {
            setUpMap();
        }
    }
}

private void setUpMap() {
    mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker"));
}
}

Also the xml file for BasicMapActivity:

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment"/>

EDIT:

Here is the main program's XML:

<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">

<!-- As the main content view, the view below consumes the entire
     space available using match_parent in both dimensions. -->
<FrameLayout
    android:id="@+id/content_frame"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />


<!-- android:layout_gravity="start" tells DrawerLayout to treat
     this as a sliding drawer on the left side for left-to-right
     languages and on the right side for right-to-left languages.
     The drawer is given a fixed width in dp and extends the full height of
     the container. A solid background is used for contrast
     with the content view. -->
<ListView
    android:id="@+id/left_drawer"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:choiceMode="singleChoice"
    android:divider="@android:color/transparent"
    android:dividerHeight="0dp"
    android:background="#111"/>
</android.support.v4.widget.DrawerLayout>

As long as my manifest:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android.navigation"
android:versionCode="1"
android:versionName="1.0">

<uses-sdk android:minSdkVersion="14" android:targetSdkVersion="17" />

    android:theme="@android:style/Theme.Holo.Light.DarkActionBar"
    android:allowBackup="true">


    <activity
        android:name=".MainActivity"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

</application>

</manifest>

Could anyone give me a hint? I have been jammed here for 2-3 days.

Thank you so much!

Your issu is simple

The API KEY must be inside the Application tag, also you should put it at the end

Example : 

<application
    android:label="@string/app_name"
    android:icon="@drawable/ic_launcher"
    android:theme="@android:style/Theme.Holo.Light.DarkActionBar"
    android:allowBackup="true">

   <activity
        android:name=".MainActivity"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <meta-data android:name="com.google.android.maps.v2.API_KEY"
    android:value="AIzaSyDJbPX63ZJni6sbzNxaFvFUCnYLb7-9o28"/>

</application>

Caused by: java.lang.RuntimeException: API key not found.  Check that <meta-data  
android:name="com.google.android.maps.v2.API_KEY" android:value="your API key"/>  
is in the <application> element of AndroidManifest.xml

Get a valid API key. With out this you can't run a map V2 in your App. Here's the doc how you can get one.

Another error occurs in your xml layout for the BasicMapActivity at line #18. Please post that XML in your question.

In the error message you had two problems:

1.- "android.view.InflateException: Binary XML file line #18: Error inflating class fragment"

2.- "java.lang.RuntimeException: API key not found. Check that is in the element of AndroidManifest.xml"

The solution offered by "yume117" resolved the number 2, but I think that the problem "inflating class fragment" is due to the xml file for BasicMapActivity.

Instead of a "fragment" inside your "layout" you would need to change to something like this:

<com.google.android.gms.maps.MapView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent" />

Also you would have to change the java class. In this url is an example for controlling this (is in spanish but I think that the code is comprehensible): https://groups.google.com/forum/#!msg/desarrolladores-android/1cvqPm0EZZU/9srw_9feamUJ
