Ukuhlela i-Android: kanjani ukuba aqale ukudala izicelo zabo siqu futhi imidlalo?

UHlelo ingenye kulezo zindawo lapho wonke umuntu angakwazi ukuzwa indima umdali. Ngokuvamile, ngaphansi aqonde ukuthuthukiswa izicelo computer, zezimboni imishini units, noma umane for DIY electronic. Kodwa ekwandeni kumadivayisi eselula isikrini sokuthinta babe izinhlelo ethandwa kakhudlwana i-Android, i-iOS, noma olunye uhlelo igobolondo yalolu hlobo. Nokho, kumelwe ngivume, ibhizinisi laphakade liyathembisa. Ngakho-ke, esihlokweni kuzoxoxwa, ukuqala uHlelo i-Android kusuka ekuqaleni. Yiziphi izinto ezinganembile khona? Yiluphi ulimi olusetshenziswa ngayo?

Ukudala izinhlelo

Ngaphambi kokubhala eyakho, kumele uhlole zonke izingxenye kuyadingeka ukuba naye lo:

1. Ulimi.
2. Khetha imvelo nentuthuko. Olimini sisalokhu ahlale ngokuningiliziwe, njengoba ngempela futhi imikhiqizo software, okuzodala isicelo. Kodwa okokuqala, ake sixoxe okuncane mayelana ezindaweni nokuthuthukiswa. Evamile, zingase sehlukaniswe tincenye ezintathu:

• ihluzo;
• ezivamile;
• inthanethi.

Ukwakha izinhlelo Kumele kuqashelwe ukuthi manje kunzima ukubeka phambili umbono ukuthi ukube kwakungengenxa yaso ngaphambilini athuthukile. Ngakho-ke, lapho inkinga kwenzeka, noma uma kwenzeka nje yokuntula ulwazi oludingekile ukuze kahle kwakha ukungaqondi futhi kuyobenza babe program nakho. Bangasiza kudalwa izinhlelo izeluleko ezakhayo.

Kukuyiphi izinhlelo ulimi zilotshiwe?

Ngenxa yalezi zinjongo, zisebenzisa Java. Kufanele kuqashelwe ukuthi ngempela ulimi lokwakha izinhlelo eziyinkimbinkimbi. Kodwa ukudala izicelo zakho kungukuthi ngempela ngokuphelele ukwazi ukuthi. Kuyoba ulwazi olwanele eziyisisekelo namakhono kolwazi umsebenzi ngemuva ukuze uthole izimpendulo zemibuzo yabo. Ngaphezu kwalokho, kukhona workpiece ethile, usebenzisa okuyinto, ungathatha izinyathelo ukuze udale isicelo ngaphandle kwezinkinga abalulekile. Khona-ke izinhlelo ze-Android liphenduka ubumnandi.

Ingabe ngokuvamile abakhethiwe ukuthuthukiswa imvelo

Njengoba abadlali ezibhekwa ezimbi kakhulu Eclipse futhi-Android SDK. Bakhululekile. Ngokuvamile, kufanele kuphawulwe ukuthi imvelo nentuthuko - izimbangi sina, futhi ngamunye kubo has eziningi ubukghoni nokubhalelwa. Worth ukutadisha ngamunye wabo. Eceleni sizivumele nje kancane ukuba sigxile esicini esisodwa esithinta we-Android SDK - Emulator. Nguye uhlelo uzenza ifoni noma ithebhulethi eyehlayo on "Android". Emulator buthule abasebenza PC ejwayelekile kanye ideskithophu libukeka idivayisi yeselula ejwayelekile. Kukhona isici esiyingqayizivele - it is elawulwa usebenzisa igundane kanye ikhibhodi esikhundleni ngomunwe wakho. Ngo Emulator ungakwazi ukuhlola ukusebenza izicelo ngaphansi izandiso ahlukahlukene kwesikrini, kanye izinguqulo ezahlukahlukene mobile okusebenza "Android". Ngakho-ke, njengoba kuyinto exakayo kuwe kungase kuzwakale, kodwa ngesikhathi ukuthuthukiswa isicelo, okuhloswe ngaso Android, uneselula - akudingekile.

Yini okudingeka ukuthuthukisa isicelo sakho?

Ukwakha eyakho ngempela ukuqasha Unicode - kuyodingeka kuphela ukuba uchithe isikhathi sakho siqu futhi umzamo. Kodwa zokusebenza ezishicilelwe ku "Google Play Isitolo" Uzodinga ukuze zabiwe "google" 25 zamaRandi. Kodwa lesi samba ingaphezu ihlawulelwa, uma isicelo sidaliwe, okungase ukudala izilaleli njalo abantu abayizinkulungwane ezimbalwa. Ukwenza imali kungaba kwenziwe ngezithukuthuku e-game isevisi noma ngokusebenzisa ukukhangisa.

Isikhombimsebenzisi Development Imvelo

Lokhu kukhetha efanelekayo kulabo nakwazi mayelana izinhlelo bebonke, kodwa ngingathanda ukuthola isicelo sakho lapha futhi manje. Ukuze uqale ukufunda incazelo kanye izici ingcaca ukuthuthukiswa ezindaweni. Ngokwesibonelo, abanye bangase babeke kuphela izakhi elula futhi unamathisele ukuba ukusebenza ubuncane. izinsiza ezinjalo kufanele kugwenywe, ngoba ngosizo lwabo, bekuyoba nzima ukuqonda yikuphi ukuhlakanipha ukudala umkhiqizo wokugcina ithuthukiswe. Kungcono ukukhethwa nemingcele ezifana ukwenza:

1. Ukuba khona interface enembile.
2. Ukusebenzisa operation ecacile logic.
3. Ukukwazi ukuqamba izakhi ingcaca futhi izindlela eziyisikhombisa.
4. Ukutholakala amadokhumenti imvelo ukuthuthukisa kanye nokuseka iforamu.

Imvelo Yokuthuthuka Yangaphakathi kolayini

Abakwazi unikeze ukusebenza sasivumela ebanzi elula yokufinyelela - Inthanethi. "Imvelo Yokuthuthuka Yangaphakathi kolayini" - mhlawumbe ukuthi uthi konke. Nakuba kufanele licaciswe ukuthi izinhlelo zemidlalo i-Android namanje kunzima. Ngakho, okunzima kakhulu ukuba lusebenze abacibishelayo futhi ezifanayo yinkimbinkimbi isicelo. Kodwa uhlelo ngombhalo design futhi ukudluliswa kwedatha - kulula.

isiphetho

Sithemba izimpikiswano izinyathelo lokuqala ukulungiselela ngokudalwa izinhlelo zayo awasekho. Uma unqume ukuthi bahlanganyele sina izinhlelo, ungasebenzisa imibhalo ekhethekile. Ngokwesibonelo, incwadi ethi "Programming Android» Brian Hardy. Yiqiniso, lena akuyona kuphela umsebenzi omuhle, kodwa into kubalulekile ukuze uqale. Nakhu ukubuyekeza ngethuluzi futhi ungaqala endleleni eya empumelelweni.
