isGooglePlayServicesAvailable nullPointerException

Question

我使用此方法检查Google Play是否可用：

int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
if(status == ConnectionResult.SUCCESS) {
  do something
}

除少数设备外，一切都很好。现在，我注意到阿尔卡特ONE TOUCH 4033X和索尼C2105发生了故障。我经常在这些设备上发布崩溃报告，我不知道为什么会发生这种情况。

编辑： 在onCreated我有：

if (status == ConnectionResult.SUCCESS) 
{
    if(network_enabled) 
    {
    getLocation();
    } 
}

public void getLocation() 
    {
        clearTextFromSearch = true;
        searchEditText.setText("");

        locationClient.connect();
    }

然后在onConnected上我调用getLatAndLng（）

private void getLatAndLng() 
    {
        clearList = true;
        nPages = 0;

        clearTextFromSearch = true;
        searchEditText.setText("");

        currentLocation = locationClient.getLastLocation();

        locationClient.disconnect();

        if(currentLocation != null)
        {
            lat = currentLocation.getLatitude();
            lng = currentLocation.getLongitude();

            getShops(lat, lng, nPages);
        }
}
