Here there is the code that check the internet connection and then if the isconnected is false show a message in a allert dialog. The problem is that if isconnected is true and (i
Solution 1:
You do not need AsyncTask to check the internet connection, so please keep it simple.
I think that your onClick method should looks like this:
@OverridepublicvoidonClick(View v) {
if (isConnectionAvailable(context)) {
// connected
} else {
// not connected
}
};
publicstaticbooleanisConnectionAvailable(Context context) {
ConnectivityManagermanager= (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfonetworkInfo= manager.getActiveNetworkInfo();
return networkInfo != null && networkInfo.isAvailable() && networkInfo.isConnected();
}
Do not forget the ACCESS_NETWORK_STATE and INTERNET permissions in your Manifest.
Solution 2:
Try with this...
((Button)findViewById(R.id.listabutton)).setOnClickListener(newView.OnClickListener() {
@OverridepublicvoidonClick(View v) {
if(isDeviceOnline(context)){
//do something.
}else{
AlertDialog.Builder dialog= newAlertDialog.Builder(context);
dialog.setMessage("Not connected");
dialog.setTitle("Error!");
dialog.setPositiveButton(.....);
dialog.create();
dialog.show();
}
}
}
publicbooleanisDeviceOnline(Context context) {
ConnectivityManagermanager= (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfonetworkInfo= manager.getActiveNetworkInfo();
return networkInfo != null && networkInfo.isAvailable() && networkInfo.isConnected();
}
And yes, add ACCESS_NETWORK_STATE and INTERNET permissions in the manifest file
