Solution

ConnectivityManager mConnectivity;
TelephonyManager mTelephony;

// Skip if no connection, or background data disabled
NetworkInfo info = mConnectivity.getActiveNetworkInfo();
if (info == null || !mConnectivity.getBackgroundDataSetting()) {
    return false;
}
Note

From Developer Documentation:

This method was deprecated in API level 14. As of ICE_CREAM_SANDWICH, availability of background data depends on several combined factors, and this method will always return true. Instead, when background data is unavailable, getActiveNetworkInfo() will now appear disconnected.
