java - Start (Register) service on andriod boot (Start up) -


am new android, develop app can receive sms , process message.

i have taken around web on how receive sms , bellow code attempting use.

public class smslistener extends broadcastreceiver {     string r_message;     private sharedpreferences preferences;     @override     public void onreceive(context context, intent intent) {         // todo auto-generated method stub         if (intent.getaction().equals("android.provider.telephony.sms_received")) {             bundle bundle = intent.getextras(); //---get sms message passed in---             smsmessage[] msgs = null;             string msg_from;             if (bundle != null) {                 //---retrieve sms message received---                 try {                     object[] pdus = (object[]) bundle.get("pdus");                     msgs = new smsmessage[pdus.length];                     (int = 0; < msgs.length; i++) {                         msgs[i] = smsmessage.createfrompdu((byte[]) pdus[i]);                         msg_from = msgs[i].getoriginatingaddress();                         string msgbody = msgs[i].getmessagebody();                     }                     return;                 } catch (exception e) {                     //log.d("exception caught",e.getmessage());                     r_message = "no message received";                     return;                 }             }         }     } }

and here code found can start service app can working on background

public class smsservice extends intentservice {    /**    * constructor required, , must call super intentservice(string)    * constructor name worker thread.    */   public smsservice() {       super("smsservice ");   }   @override   protected void onhandleintent(intent intent) {       // work here, download file.       // our sample, sleep 5 seconds.       try {           thread.sleep(5000);       } catch (interruptedexception e) {           // restore interrupt status.           thread.currentthread().interrupt();       }   } }

ref: https://developer.android.com/guide/components/services.html

i created file(s) smslistener.java , smsservice.java in manifest have 

<receiver android:name=".smslistener">     <intent-filter>         <action android:name="android.provider.telephony.sms_received" />     </intent-filter> </receiver>  permission:  <uses-permission android:name="android.permission.receive_sms" />

but don't know how call above 2 java processes , call them can verify app receiving sms , ll continue when closed.

note: app have 2 services needs working every-time on background please show me how add second service.

any apprenticed thanks

as receivers declared in manifest file smslistener class automatically triggered when ever message received can process info in smslistner

for more info refer https://developer.android.com/reference/android/content/broadcastreceiver.html

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
