parse.initialize(this, parse_app_id, parse_client_key); parseacl defaultacl = new parseacl(); defaultacl.setpublicreadaccess(true); parseacl.setdefaultacl(defaultacl, true); pushservice.setdefaultpushcallback(this, mainactivity.class); parseinstallation.getcurrentinstallation().getinstallationid(); parseinstallation.getcurrentinstallation().saveinbackground(); 

and subscribe:

pushservice.subscribe(this, username, detail.class); 

in manifest

i want register 1 time on device. there should not issue if app installed multiple time in device.please me, in advance.

in case samsung tab 3 registers twice same uniqueid. uniqueid marked unique column in parse db? or should make unique? if yes, how?

i think mukul has provided great cloud code issue

here

parse.cloud.beforesave(parse.installation, function(request, response) { parse.cloud.usemasterkey(); var query = new parse.query(parse.installation); query.equalto("owner", request.user); query.equalto("uniqueid", request.object.get("uniqueid")); query.first().then(function(duplicate) {     if (typeof duplicate === "undefined") {         console.log("duplicate not exist,new installation");         response.success();     } else {         console.log("duplicate exist..trying delete " + duplicate.id);         duplicate.destroy().then(function(duplicate) {             console.log("successfully deleted duplicate");             response.success();         }, function() {             console.log(error.code + " " + error.message);             response.success();         });      } }, function(error) {     console.warn(error.code + error.message);     response.success(); }); }); 

note owner username or primary key think u can use.

here's link of same better explanation mukul https://www.parse.com/questions/check-for-duplicate-installations-of-same-user-on-re-installation-of-app
