How to check and set Default setting value on App initialization?

Friends,

I need to check the settings values set in app.component.ts , initializeApp() function … I try a code

initializeApp()
 {
     
 
 // some other code

 this.setDefault();
 


 }
 async setDefault()
 {
   let lbid = await this.storage.get('lbid');
   let lbname = await this.storage.get('lbname');
   let distid = await this.storage.get('distid');
   let lbtype = await this.storage.get('lbtype');
   if(lbid) {
     alert("set");
   } else {
     alert("not set mone");
   }

 }

my requirement is if not set that values , set Default values in function setDefault
for lbid,lbname,distid,lbtype
but now after apk generated the app loading indefinitely not show home page

Any body please help…
