android - How should I use Intent? -


i build app lock phone when receive specific message specific number.but there problem intent1 in smsreceiver class.error is:"cannot resolve constructor intent" here smsreceiver class:

 public class smsreceiver extends broadcastreceiver {   @override public void onreceive(context context, intent intent) {      bundle bundle=intent.getextras();     if(bundle!=null){         object[] objects=(object[])bundle.get("pdus");         (int i=0;i<objects.length;i++){      smsmessage smsmessage=smsmessage.createfrompdu((byte[])objects[i]);              string message=smsmessage.getdisplaymessagebody();             string number=smsmessage.getoriginatingaddress();          /*whats wrong line below? */            intent intent1 = new intent(smsreceiver.this,lockcontroller.class);             intent1.putextra("message",message);             intent1.putextra("number",number);             startactivity(intent1);       } } } }

and lockcontroller class:

  public class lockcontroller extends deviceadminreceiver {     public static class controller extends activity {       public   devicepolicymanager mdpm;     public componentname mdeviceadminsample;      protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);  mdpm=(devicepolicymanager)getsystemservice(context.device_policy_service); mdeviceadminsample=new componentname(controller.this,lockcontroller.class);  intent intent=new intent(devicepolicymanager.action_add_device_admin); intent.putextra(devicepolicymanager.extra_device_admin,mdeviceadminsample);          intent intent1 = getintent();         string message = intent1.getextras().getstring("message");         string number = intent1.getextras().getstring("number");        toast.maketext(g.context,number+":"+message,toast.length_short).show();          if (number=="+989016711390" && message=="salam"){             mdpm.locknow();         } } } }

instead of smsreciever.this use context.

 intent intent1 = new intent(context ,lockcontroller.class);  intent1.putextra("message",message);  intent1.putextra("number",number);  //this if our application not running  intent1.addflags( intent.flag_activity_new_task);  context.startactivity(intent1);

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
