How can I wait for 10 second without locking application UI in android [duplicate]

Question

I am stuck with a problem, I want to wait 10 second because I want my application to start the code below after that 10 sec but without stopping that person from clicking anything else in the application (without calling Thread.sleep();).

try {     Log.v("msg", "WAIT CheckFrequencyRun");     Thread.sleep(10000); // giving time to connect to wifi         } catch (InterruptedException e) {     // TODO Auto-generated catch block     e.printStackTrace();    }    //if no network    if(wifiManager.getConnectionInfo().getNetworkId()==-1){     //stop wifi     wifiManager.setWifiEnabled(false);     Log.v("msg", "no connection");     handler.postDelayed(this, checkInterval);    }    //else connection    else{     Log.v("msg", "connection");     onDestroy();    }

You can use this:

Handler handler = new Handler(); handler.postDelayed(new Runnable() {     public void run() {      // Actions to do after 10 seconds     } }, 10000); 

For Stop the Handler, You can try this: handler.removeCallbacksAndMessages(null);
