android - Best way to communicate a service with an activity (broadcast, callbacks, etc) -

what have:

i have library running on process using aidl. have app uses library, , on messaging activity, connect service send messaging , have broadcast receiver manage incoming messages.

the problem?

if library going used 2 apps on same device broadcast actions going same, , have problems when send broadcast.

what doubt?

what best way "listen" new incoming messages receive on library , send app. maybe callback? or there better solution?

more information

the library provides few methods start session, , other methods send different type of messages (images, text, locations, etc...) , receive callback library, uses c , c++, when new message incoming.

if need more information feel free ask.

my code:

iremote.aidl

interface iremote {     int sendtextmessage(string to, string message);  } 

wrapperlibrary.java

public class mylibrary extends service {      // current context, used sendbroadcast() @callbacks      private context mcontext = this;      private static mylibrary instance = new mylibrary();      //executor start new thread service.     final executorservice service;      @override     public ibinder onbind(intent arg0) {         //return interface.         return mbinder;     }      /** return current instance */     public static wrapperlibrary getinstance() {         return instance;     }  private final iremote.stub mbinder = new iremote.stub() {          @override         public int sendtextmessage(string to, string message)                 throws remoteexception {               log.d(tag, "send text message. ");             int = -1;             future<integer> task;             task = service.submit(new callable<integer>() {                 public integer call() {                     return tu.tu_message_send_text(to, message);                 }             });             try {                 = task.get();             } catch (exception e) {                 log.e(tag, "send text message: exception *** " + e.getmessage());             }              log.d(tag, "send text message: status code: " + i);              return 0;         }  } 

callbacks.java

public class callbacks extends jnicallback {      private context mcontext;       public callbacks(context context) {         this.mcontext = context;     }      public void on_incoming_text_message(final string from, final string message) {          log.d(tag, " incoming text message from:" + + " message: " + message);         intent = new intent(broadcastactions.incoming_text_message);         i.putextra("from", from);         i.putextra("message", message);         mcontext.sendbroadcast(i);      }  } 

mainactivity.java on activity have broadcast receiver , can update ui new message

    public class messagereceiver extends broadcastreceiver {         @override         public void onreceive(context context, intent intent) {              bundle = intent.getextras();             string incomingmessage = "";              if(extra != null) {                  incomingmessage = extra.getstring("message");                 addnewmessage(new message(incomingmessage, false));             }              toast.maketext(messagingactivity.this, "incoming message", toast.length_long).show();          }      }; 

i going suggest use localbroadcastmanager or if becomes messy eventbus, if service runs in own process (which not i'm sure about) messaging not passed 1 process other.

so suggest define broadcast action service in strings.xml , make different every app. of course, you'll have careful you'll need update receiver action every app.
