Could not find class 'com.google.android.gms.maps.MapFragment'

Question

I know there are a lot of questions like this one, and I searched everything I could, but I wasn't able to find an answer. So, I think I did everything well, but it's still giving me this error.

main.xml:

<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" >

<fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.MapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

</RelativeLayout>

MainActivity.java:

package com.davidmilicevic97.testapp;

import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;

import android.app.Activity;
import android.os.Bundle;
import android.widget.Toast;

public class MainActivity extends Activity {

private GoogleMap googleMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    try {
        initializeMap();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

@Override
protected void onResume() {
    super.onResume();
    initializeMap();
}

private void initializeMap() {
    if (googleMap == null) {
        googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                R.id.map)).getMap();

        if (googleMap == null) {
            Toast.makeText(getApplicationContext(),
                    "Sorry! Unable to create maps.", Toast.LENGTH_SHORT)
                    .show();
        }
    }
}

}

I imported google-play-services_lib through the Eclipse and used it as a library for my project. I think i don't have to use SupportMapFragment because my MinSdkVersion is 14. Also, I added both Google Play Services version and API key to my manifest, and I think I added all permissions I had to, so I really don't know where is the problem.

I would be very grateful if anyone could check my problem.

Well, if that is what I think, then I did it. Can you just explain it to me shortly? — davidmilicevic97, Jul 07 '14 at 15:21

This is more of a comment, but I cannot yet comment, so here goes:

In v2 for google maps, you don't need the following lines:

<permission
android:name="com.davidmilicevic97.testapp.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
<uses-permission android:name="com.davidmilicevic97.testapp.permission.MAPS_RECEIVE" />

I don't see anything wrong with your code (the code should run even with the above, they are ignored).

This could very well be an Eclipse issue. So the following is from my experience, you might want to give it a go:

First, do a 'clean' and build. Second, in the Properties>Android of your project, select Google APIs and apply and then change to Android API and apply again.

I've had issues several times where my project wouldn't properly build, but doing the above seems to do a 'reset'. You might even want to restart Eclipse.
