I-ejensi yokuthuthukisa uhlelo lokusebenza lwe-Android

Uhlelo oluhle lwe-Android App Entwicklung Agentur luzoba nethimba lekhwalithi ephezulu elikwazi ukuletha imiphumela oyojabula ngayo.. I-Brightsolutions ingenye yezinkampani ezinjalo. Banekomkhulu e-Eberbach bei Mannheim futhi baziwa ngamahora abo okuthuthukisa e-Android athengekayo. Amahora avumayo, nokho, akusho ukuthi bayeqa izinga. Lawa ma-Android-Entwickler e-Mannheim asebenza ngamazinga aphezulu, ukunakekela, nomdlandla.

I-Kotlin manje isiwulimi olusemthethweni lwe-Android-App-Entwicklung

I-Google isimemezele ukuthi i-Kotlin manje isiwulimi olusemthethweni lwe-Android App Development. Lolu limi olusha lunenani lezinzuzo nge-Java, kufaka phakathi isivinini esikhulu kanye nekhodi encane. Ulimi lwakhiwe ngabakwaJetBrains, inkampani efanayo eyakha i-IntelliJ IDEA. Ulimi oluncanyelwayo lonjiniyela be-Android. Nokho, onjiniyela abakhetha i-Java noma i-C++ basengasebenzisa ulimi.

Ukusebenzisa i-Kotlin kulula futhi kuyabiza. Iphinde ibe umthombo ovulekile, ngakho-ke azikho izimali zamalayisense. Njengoba kumahhala, abantu abaningi bayayifunda futhi baba nekhono kuyo. Futhi njengoba i-Kotlin kuwulimi olusemthethweni lwe-Android App Entwicklung, izinkampani eziningi ziguqula amaphrojekthi azo wokuthuthukisa ukuze ziyisebenzise. I-Kotlin isivele isetshenziswa ngabakwa-Uber, I-Trello, Isikwele, kanye ne-Coursera.

Ngoba kulula ukuyinakekela kune-Java, I-Kotlin idinga imigqa embalwa yekhodi kune-Java. Ngaphezu kwalokho, I-Kotlin ilula futhi ihlanzekile kune-Java, okusho izimbungulu ezimbalwa. Ukwengeza, isikhathi esifushane sokuthuthukisa sizophinde sinciphise izindleko. Ukwengeza, ngoba ulimi alusebenzisi inkumbulo eningi, Abathuthukisi be-Kotlin bangangeza ukusebenza okwengeziwe ezingxenyeni ezikhona ngaphandle kokubhala amakhodi amaningi.

Isinqumo phakathi kwe-Java ne-Kotlin sincike kakhulu ekutheni iphrojekthi yakho iyinkimbinkimbi kangakanani nokuthi ubani ozoyithuthukisa. Ngokwesibonelo, uma uthuthukisa enkulu, uhlelo lokusebenza oluyinkimbinkimbi, kungase konge kakhulu ukusebenzisa i-Java. Futhi kungase kube lula ukuthola abathuthukisi be-Java eminyakeni emihlanu noma eyishumi. Nokho, uma wakha encane, uhlelo lokusebenza olusheshayo, kungase kube lula ukuyigcina kanye nekhodi e-Kotlin.

Izinhlelo zokusebenza zomdabu ze-Android zinikeza ukuhlanganiswa okuhle nokusebenza okuphezulu kohlelo lokusebenza

Inzuzo enkulu yokuthuthukiswa Kwezinhlelo Zokusebenza ze-Android kunezinye izindlela zokuthuthukisa izinhlelo zokusebenza zeselula ukusebenza kwazo okuphezulu nokuhlanganiswa. Ikhodi ebhalelwe izinhlelo zokusebenza zomdabu ifundeka kalula futhi ihlaziywe. Ngaphezu kwalokho, lezi zinhlelo zokusebenza zinenzuzo yokusebenzisa ihadiwe nezingxenye ze-UI zomdabu, enikeza ukusebenza okusezingeni eliphezulu, isikhombikubona sokuzula esicacile, kanye nomklamo okhanga kakhulu. Lokhu kuwenza abe yinketho ekhethwayo yokuthuthukiswa kohlelo lokusebenza lweselula.

Izinhlelo zokusebenza zomdabu ze-Android zithandwa kakhulu phakathi konjiniyela ngenxa yokuhambisana kwazo nezinga eliphezulu lokwenza ngendlela oyifisayo. Ngenxa yalokho, banikeza ukusebenza okuphezulu nokuhlanganiswa. Izinhlelo zokusebenza eziningi ezaziwayo zenziwe kusetshenziswa le ndlela, okuhlanganisa i-LinkedIn, PokémonGo, kanye ne-Google Maps. Ukuthuthukiswa kohlelo lokusebenza lomdabu kubaluleke kakhulu ngoba amadivayisi eselula asetshenziswa usohambweni futhi ukusebenza kohlelo lokusebenza kuyisici esibalulekile kulwazi lomsebenzisi.. Ngokocwaningo, 80% wabasebenzisi bazozama uhlelo lokusebenza kanye ngaphambi kokunquma ukulithenga. Ukusebenza kancane kancane kungajikisa abasebenzisi abahle.

Enye inzuzo yezinhlelo zokusebenza zomdabu ukuthi zingashintshwa kalula ngokusekelwe kumpendulo yomsebenzisi futhi zingabuyekezwa ukuze zihlanganise izici ezintsha ezisekelwe ezidingweni zemakethe.. Lokhu kugcina izinhlelo zokusebenza zisesikhathini samanje ngenqubekelaphambili nobuchwepheshe. Umthuthukisi wohlelo lokusebenza lweselula ochwepheshe angakweluleka ngendlela engcono kakhulu yokuthuthukisa futhi anikeze impendulo ngomqondo wephrojekthi yakho. Inzuzo yezinhlelo zokusebenza zomdabu ukuthi zidinga izinsiza ezimbalwa futhi zinikeza ulwazi olungcono kakhulu lomsebenzisi.

Izinhlelo zokusebenza zomdabu ze-Android zigcina idatha endaweni kumadivayisi eselula

Izinhlelo zokusebenza zomdabu ze-Android zingagcina idatha endaweni kumadivayisi eselula futhi ziqhubeke kukho konke ukuqalisa kabusha. Kunezindlela eziningana zokwenza lokhu. I-Android inikeza izindlela ezintathu ezibalulekile zokugcina idatha: i-database ye-SQLite, Amafayela Asendaweni, kanye Namasethi Amanani Abalulekile. Ukukhetha ukuthi iyiphi ozoyisebenzisa kuncike ekukhathazekeni kwakho kwangasese, ukufinyeleleka kwezinye izinhlelo zokusebenza, kanye nezidingo zendawo. Ake sihlole indlela ngayinye ukuze siqonde izinzuzo nezingozi zayo.

Lapho uthuthukisa uhlelo lwe-Android, ungasebenzisa isitoreji sangaphakathi nesangaphandle sedivayisi yeselula. Zombili izindlela zigcina idatha endaweni kudivayisi, kodwa isitoreji sangaphandle sivikeleke kakhulu. Isitoreji sangaphakathi sisetshenziswa uhlelo lokusebenza, kuyilapho isitoreji sangaphandle sifinyeleleka kuwo wonke umuntu. Kubalulekile ukusebenzisa inketho yesitoreji sangaphandle uma idatha iyimfihlo, kodwa qiniseka ukuthi uyayisusa ngemva kokuyisebenzisa. Uma uhlelo lokusebenza ludinga ukugcina idatha engenayo indlela yomphakathi, ungasebenzisa isitoreji sangaphakathi esikhundleni salokho.

Inketho yokuqala ukusebenzisa isitoreji se-SQLite, okuyisizindalwazi esisekelwe kufayela esilungele ukugcina idatha ehlelekile. Le nketho yesitoreji ingcono kakhulu kuzinhlelo zokusebenza ezivame ukubuyekeza idatha yazo. Uma ungafuni ukuthi idatha yakho ifinyeleleke kwezinye izinhlelo zokusebenza, ungasebenzisa inhlanganisela yazo zombili izinketho. Uma udinga ukugcina idatha endaweni kudivayisi yakho yeselula, ungasebenzisa i-SQLite database. Kodwa khumbula ukuthi lezi zinketho zokugcina idatha zinganqunyelwa.
