    @Override

            getNearMeLocation();
    }

    @Override
    public void onDisconnected() {
    }
}

I didn't know how to solve this.Anybody can help me with this.Thank You.

Here The Problem is that you are calling method on LocationClient while it is not connected to the play services.

replace your getNearMeLocation() method with the following:

public void getNearMeLocation() {
if(mLocationClient.isConnected()){
    Location currentLocation = mLocationClient.getLastLocation(); ----> 264th line
    if (currentLocation != null) {
        (new LocLoader(getApplicationContext())).execute(currentLocation);
    } else {
        Toast.makeText(getApplicationContext(), "Location not available...", Toast.LENGTH_SHORT).show();
    }

}
