Mobile Frameworks - Android/iOS/Windows

Mobile app development is getting increasingly popular as the world is becoming digitized and gadget savy. There are several OS like Android,iOS, Windows for which development is being done for these devices. These devices include mobile devices, such as personal digital assistants, enterprise digital assistants or mobile phones. These applications can be pre-installed on phones during manufacturing platforms, or delivered as web applications using server-side or client-side processing (e.g., JavaScript) to provide an “application-like” experience within a Web browser. Application software developers also must consider a long array of screen sizes, hardware specifications, and configurations because of intense competition in mobile software and changes within each of the platforms. Mobile app development has been steadily growing, in revenues and jobs created.

Mobile Frameworks Interview Questions

1.​ ​When​ ​to​ ​use​ ​Xamarin.Forms​ ​vs​ ​Xamarin​ ​Native?
· Apps​ ​that​ ​require​ ​little​ ​platform-specific​ ​functionality
· Apps​ ​where​ ​code​ ​sharing​ ​is​ ​more​ ​important​ ​than​ ​custom​ ​UI.

Xamarin.IOS,Xamarin.Android: · Apps​ ​that​ ​require​ ​specialized​ ​interactions
· Apps​ ​with​ ​highly​ ​polished​ ​design.
· Apps​ ​that​ ​use​ ​many​ ​platform-specific​ ​APIs.
· Apps​ ​where​ ​custom​ ​UI​ ​is​ ​more​ ​important​ ​than​ ​code​ ​sharing.

2.​ ​What​ ​happens​ ​during​ ​the​ ​lifecycle​ ​of​ ​a​ ​React​ ​component?
At​ ​the​ ​highest​ ​level,​ ​React​ ​components​ ​have​ ​lifecycle​ ​events​ ​that​ ​fall​ ​into three​ ​general​ ​categories: · Initialization
· State/Property​ ​Updates
· Destruction
Every​ ​React​ ​component​ ​defines​ ​these​ ​events​ ​as​ ​a​ ​mechanism​ ​for managing​ ​its​ ​properties,​ ​state,​ ​and​ ​rendered​ ​output.​ ​Some​ ​of​ ​these​ ​events only​ ​happen​ ​once,​ ​others​ ​happen​ ​more​ ​frequently.

3​.​ ​​Mention​ ​what​ ​are​ ​the​ ​storage​ ​option​ ​does​ ​PhoneGap​ ​can​ ​access?
· Memory-store.js​ ​(MemoryStore)
· Websql-store.js​ ​(WebSqlStore)
· Is-store.js​ ​(LocalStorageStore)

4​.​ ​​Can​ ​Jasmine​ ​and​ ​Karma​ ​be​ ​used​ ​with​ ​NativeScript?
Yes.​ ​They​ ​are​ ​JavaScript​ ​based​ ​and​ ​do​ ​not​ ​have​ ​browser​ ​dependencies and​ ​should​ ​work​ ​out​ ​of​ ​the​ ​box.

5.What’s​ ​The​ ​Difference​ ​Between​ ​“ionic​ ​Build”​ ​And​ ​“ionic​ ​Prepare”?
· Ionic​ ​prepare​ ​<platform>​ ​copies​ ​all​ ​files​ ​from​ ​the​ ​www​ ​folder​ ​into​ ​the​ ​target platform’s​ ​www​ ​folder.
· Ionic​ ​build​ ​<platform>​ ​also​ ​does​ ​this,​ ​but​ ​also​ ​builds​ ​the​ ​app’s​ ​source​ ​code so​ ​that​ ​it​ ​can​ ​be​ ​run​ ​on​ ​a​ ​simulator/emulator​ ​or​ ​a​ ​device.

6.Which​ ​type​ ​of​ ​GUI​ ​is​ ​supported​ ​by​ ​Sencha​ ​Touch?
GUI​ ​Support: Easily​ ​scales​ ​to​ ​different​ ​resolutions​ ​for​ ​maximum​ ​compatibility​ ​with different​ ​iPhone,​ ​iPad,​ ​and​ ​the​ ​various​ ​Android​ ​phones · HTML5​ ​and​ ​CSS3​ ​allow​ ​higher​ ​flexibility.
