I don't want my app to crash if the user doesn't have wifi or 3g connectivity. How can I catch this at runtime in my app?
A:
First get a reference to the ConnectivityManager and then check the Wifi and 3G status of the device. You'll need the ACCESS_NETWORK_STATE permission to use this service.
ConnectivityManager connManager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);
NetworkInfo mWifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
NetworkInfo mMobile = connManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
if (mWifi.isAvailable() == false && mMobile.isAvailable() == false) {
showDialog(DIALOG_NETWORK_UNAVAILABLE);
}
