Issue
I have a problem with checking internet connection in android at runtime. I use some different methods to check internet connection but i don't know which one is better . because each of them have some problems .
Method 1 check internet connection by pinging Google :
Runtime runtime = Runtime.getRuntime();
try {
Process mIpAddressProcess = runtime.exec("/system/bin/ping -c 1 8.8.8.8");
int mExitValue = mIpAddressProcess.waitFor();
return mExitValue == 0;
} catch (InterruptedException | IOException ignore) {
ignore.printStackTrace();
}
Method 2 check internet connection by ConnectivityManager :
public boolean checkNetwork() {
ConnectivityManager internetManager = (ConnectivityManager) activity.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = internetManager.getActiveNetworkInfo();
return (networkInfo != null && networkInfo.isConnected() && networkInfo.isAvailable() && networkInfo.isConnectedOrConnecting());
}
I use method 1 inside an async task, but it doesn't work correctly sometimes and slow down the app, and Method 2 (ConnectivityManager) doesn't check internet connection , it checks only network connection !
Solution
I'm using broadcast to check the connection every time. Create a class for connection info.
import android.content.Context;
import android.content.ContextWrapper;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
public class ConnectivityStatus extends ContextWrapper{
public ConnectivityStatus(Context base) {
super(base);
}
public static boolean isConnected(Context context){
ConnectivityManager manager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo connection = manager.getActiveNetworkInfo();
if (connection != null && connection.isConnectedOrConnecting()){
return true;
}
return false;
}
}
Apply code into your Activity:
private BroadcastReceiver receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
if(!ConnectivityStatus.isConnected(getContext())){
// no connection
}else {
// connected
}
}
};
Register broadcast in your activity's onCreate()
method:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_layout);
your_activity_context.registerReceiver(receiver, new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION));
..
...
....
}
Don't forget to unregistered/register on Activity cycle:
@Override
protected void onResume() {
super.onResume();
your_activity_context.registerReceiver(receiver, new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION));
}
@Override
protected void onPause() {
super.onPause();
your_activity_context.unregisterReceiver(receiver);
}
