Check if correct Google Play Service available: "Unfortunately application has stopped working"

Application Crashes every time I run it on my phone. Is there something wrong? It says Unfortunately "appname" has stopped working. I have also tried other approaches to checking for googleplay services but it always crashes. I updated my google play services and have a working google map v2 working perfectly. Any solutions to this code? It crashes on my phone running android 4.1.2 and on my AVD.

package com.example.checkgoogleplayproject;

import android.app.Activity;
import android.app.Dialog;
import android.os.Bundle;
import android.view.Menu;
import android.widget.TextView;

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GooglePlayServicesUtil;

public class MainActivity extends Activity {

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

        // Getting reference to TextView to show the status
        TextView tvStatus = (TextView)findViewById(R.id.tv_status);

        // Getting status
        int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext());

        // Showing status
        if(status==ConnectionResult.SUCCESS)
            tvStatus.setText("Google Play Services are available");
        else{
            tvStatus.setText("Google Play Services are not available");
            int requestCode = 10;
            Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode);
            dialog.show();
        }
    }

    @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;
    }
}

To check if GooglePlayServices available or not, Use GoogleApiAvailability.isGooglePlayServicesAvailable(), As GooglePlayServicesUtil.isGooglePlayServicesAvailable() deprecated.

public boolean isGooglePlayServicesAvailable(Context context){
    GoogleApiAvailability googleApiAvailability = GoogleApiAvailability.getInstance();
    int resultCode = googleApiAvailability.isGooglePlayServicesAvailable(context);
    return resultCode == ConnectionResult.SUCCESS;  
}

Update: Check if google play service available, If google play service is not available and error is recoverable then open a dialog to resolve an error.

public boolean isGooglePlayServicesAvailable(Activity activity) {
    GoogleApiAvailability googleApiAvailability = GoogleApiAvailability.getInstance();
    int status = googleApiAvailability.isGooglePlayServicesAvailable(activity);
    if(status != ConnectionResult.SUCCESS) {
        if(googleApiAvailability.isUserResolvableError(status)) {
              googleApiAvailability.getErrorDialog(activity, status, 2404).show();
        }
        return false;
    }
    return true;
}

I dont know where to post this but difficulty in correct workflow of google play services checking is mind blowing, I am using some custom classes, but you may get a point...

protected boolean checkPlayServices() {
    final int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(activity());
    if (resultCode != ConnectionResult.SUCCESS) {
        if (GooglePlayServicesUtil.isUserRecoverableError(resultCode)) {
            Dialog dialog = GooglePlayServicesUtil.getErrorDialog(resultCode, activity(),
                    PLAY_SERVICES_RESOLUTION_REQUEST);
            if (dialog != null) {
                dialog.show();
                dialog.setOnDismissListener(new OnDismissListener() {
                    public void onDismiss(DialogInterface dialog) {
                        if (ConnectionResult.SERVICE_INVALID == resultCode) activity().finish();
                    }
                });
                return false;
            }
        }
        new CSAlertDialog(this).show("Google Play Services Error",
                "This device is not supported for required Goole Play Services", "OK", new Call() {
                    public void onCall(Object value) {
                        activity().finish();
                    }
                });
        return false;
    }
    return true;
}
