Question & Answer :
I received a AsyncTask that is expected to cheque the web entree to a adult sanction. However the doInBackground() is ne\’er timed retired. Anybody person a hint?
national people HostAvailabilityTask extends AsyncTask<Drawstring, Void, Boolean> { backstage Chief chief; national HostAvailabilityTask(Chief chief) { this.chief = chief; } protected Boolean doInBackground(Drawstring... params) { Chief.Log("doInBackground() isHostAvailable():"+params[zero]); attempt { instrument InetAddress.getByName(params[zero]).isReachable(30); } drawback (UnknownHostException e) { e.printStackTrace(); } drawback (IOException e) { e.printStackTrace(); } instrument mendacious; } protected void onPostExecute(Boolean... consequence) { Chief.Log("onPostExecute()"); if(consequence[zero] == mendacious) { chief.setContentView(R.format.splash); instrument; } chief.continueAfterHostCheck(); } }
If the instrumentality is successful airplane manner (oregon presumably successful another conditions wherever location’s nary disposable web), cm.getActiveNetworkInfo() volition beryllium null, truthful you demand to adhd a null cheque.
Modified (Eddie’s resolution) beneath:
national boolean isOnline() { ConnectivityManager cm = (ConnectivityManager) getSystemService(Discourse.CONNECTIVITY_SERVICE); NetworkInfo netInfo = cm.getActiveNetworkInfo(); instrument netInfo != null && netInfo.isConnectedOrConnecting(); }
Besides adhd the pursuing approval to the AndroidManifest.xml:
<makes use of-approval android:sanction="android.approval.ACCESS_NETWORK_STATE" />
1 another tiny component, if you perfectly demand a web transportation astatine the fixed component successful clip, past it mightiness beryllium amended to usage netInfo.isConnected() instead than netInfo.isConnectedOrConnecting. I conjecture this is ahead to the idiosyncratic usage-lawsuit nevertheless.
