android method to check whether the phone and wireless are connected

This article is an example of android check whether the mobile phone and wireless connection implementation code, to share for your reference. The specific methods are as follows:

Method 1:

The main function codes are as follows:

ConnectivityManager manager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

NetworkInfo info = manager.getActiveNetworkInfo();

if(info!=null && info.isConnected()){

return true;

}else{

return false;

}

Method 2:

The main function codes are as follows:

TelephonyManager manager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

int state = manager.getDataState();

if(state == TelephonyManager.DATA_CONNECTED){

urn true;

}else{

urn false;

}

Method 1 can check the mobile phone connection and the state of wireless connection

Method 2 can only check the connection status of the phone, not the wireless connection status of the phone (i.e., if the phone does not have a phone card, but has a wireless connection, it will return false)
