Lwenkqubo for Android: ukuqalisa indlela ukudala izicelo zabo nemidlalo?

Programming yenye yezo ndawo apho wonke ubani azive kwindima umdali. Ngokuqhelekileyo, phantsi kwakhe aqonde uphuhliso izicelo iikhompyutha zobuqu, izixhobo iiyunithi zoshishino, okanye nje DIY elektroniki. Kodwa ukwanda kwezixhobo isikrini mobile zibe iinkqubo zithandwa ngakumbi Android, iOS, okanye ezinye iqokobhe inkqubo kolu hlobo. Kulungile, Mandivume, ishishini ithemba. Ngenxa yoko, kweli nqaku siza kuqwalaselwa, ukuba baqalise lwenkqubo for Android ukusuka ekuqaleni. Ziziphi iinkalo akhona? Loluphi ulwimi?

ukudala iinkqubo

Phambi kokuba ubhale inkqubo yakho, kufuneka uhlole onke amacandelo afunekayo kulo:

1. Ulwimi.
2. Khetha indawo sophuhliso. Ngolwimi sisese kuhlala iinkcukacha, njengoko, eneneni, kwaye ziziveliso ze-software, nto leyo eya kudala isicelo. Kodwa kuqala, makhe sithethe kancinci malunga bume yophuhliso. Ngokuqhelekileyo, zingakotshwa zahlulwe amacandelo amathathu:

• graphics;
• eqhelekileyo;
• intanethi.

Ukwenza iinkqubo kufuneka kuqatshelwe ukuba ngoku kunzima ukubeka phambili umbono ibingayi yenziwe ngaphambili. Ngoko ke, xa kukho ingxaki, okanye nje xa yokuswela ulwazi oluyimfuneko ukuqulunqa ngokuchanekileyo ukungaqondani kwaye isibheno badwelisi benkqubo abanamava ngakumbi. Abanako kunceda ekudalweni zeeprogram iingcebiso ezakhayo.

Apho iinkqubo zolwimi abhalwe?

Ukuze ezi njongo, sebenzisa Java. Kufuneka kuqatshelwe ukuba kakhulu ulwimi esimbaxa lokwakha. Kodwa ukwenza izicelo zakho akuthethi kuthi asazi ngokupheleleyo oko. Kuya kuba nolwazi olwaneleyo olusisiseko kunye nezakhono nolwazi yomsebenzi imvelaphi ukufumana iimpendulo zemibuzo yabo. Ukongeza, kukho workpiece ethile, esebenzisa leyo, ungakwazi ukuthatha amanye amanyathelo ukwenza isicelo ngaphandle naziphi na iingxaki ezibalulekileyo. Emva koko lwenkqubo for Android iba mnandi.

Ingaba okusingqongileyo uphuhliso ngokuqhelekileyo okhethiweyo

Njengoko abadlali zithathwa kakhulu kakhulu Eclipse kunye Android SDK. Bakhululekile. Ngokubanzi, kufuneka kuqatshelwe ukuba bume yophuhliso - okhuphisana kakhulu, yaye ngamnye kubo eziliqela amandla kunye nobuthathaka. Worth ukufunda ngamnye kubo. Ngokwahlukeneyo sivumele nje kancinane ukuba inkalo ye-Android SDK - email. Nguye yiprogram uzenza ukuba ifowuni okanye ipilisi isebenza "Android". cwaka enomzami wokulungisa indlela abasebenza kwi-PC standard kwaye i desktop ejongeka njenge isixhobo standard yeselula. Kukho inkalo ekhethekileyo - it ilawulwa usebenzisa i mouse kunye nebhodi yezitshixo endaweni ngomnwe wakho. Xa enomzami wokulungisa ungavavanya ukusebenza ngezicelo phantsi Izandiso ezahlukeneyo kwekhusi, kwakunye kwiinguqulelo ezahlukeneyo mobile Indlela yokusebenza "Android". Ngoko ke, njengoko akuqhelekanga kuni mhlawumbi ixilongo, kodwa ngexesha kuphuhliso isicelo, ejolise Android, kufuneka ifowuni - akukho mfuneko.

Yintoni ekufuneka ukuphuhlisa isicelo sakho?

Ukudala inkqubo yakho ngokuyimfuneko kuqesha wenkqubo - kuya kuba yimfuneko kuphela ukuchitha ixesha kunye nomgudu. Kodwa kwizicelo epapashwe kwi "Play Store" Kuya kufuneka ukuba kwabelwane with "lasekhaya" zeerandi 25. Kodwa lesi samba ngaphezu babuyekezwe, ukuba isicelo sele yenziwe, nto leyo yenza abaphulaphuli rhoqo ngabantu amawaka aliqela. Yokwenza imali enokwenziwa ngokuncama ku-umdlalo inkonzo okanye iintengiso.

Development Environment zomzobo

Olu khetho ilungele abo bengazi lwenkqubo ngokubanzi, kodwa ungathanda ukufumana isicelo sakho apha kwaye ngoku. Ukuqala ukufunda inkcazo kunye neempawu iindawo zophuhliso ngemizobo. Ngokomzekelo, abanye beka kuphela izinto elula uwafake lisezantsi functionality. izixhobo ezinjalo kufuneka luthintelwe, ngenxa yokuba ngoncedo lwabo, bekuya kuba nzima ukuba baqonde ekuqiqeni ukudala imveliso yokugqibela luya kuphuhliswa. Uyacetyiswa ukuba ukwenza ukhetho enjalo iparameters:

1. Ubukho i-interface enobuchule.
2. Ukusebenzisa operation ecacileyo logic.
3. Ukukwazi ukwenza iielementi zegrafiki kunye iindlela ezisixhenxe.
4. Ukufumaneka documentation bume yophuhliso kunye nenkxaso iqonga leengxoxo.

Environment Development Online

Abanokuwanika indawo ebanzi ngokuya indawo yofikelelo elula - Internet. "Development Environment Online" - mhlawumbi uthi konke oku. Nangona oko kufuneka kucaciswe ukuba kweenkqubo imidlalo for Android kusenzima. Ngenxa yoko, kunzima kakhulu ukuba ziphunyezwe abatoli kunye efanayo zintsonkotha isicelo. Kodwa inkqubo kunye kuyilo itekisi kunye transmission data - kulula.

isiphelo

Siyathemba imiba amanyathelo okuqala Ukulungiselela indalo kweenkqubo zayo abasekho. Ukuba ufike kwisigqibo sokuthandana nomntu inxaxheba ngokuzimisela lwenkqubo, ungasebenzisa uncwadi ekhethekileyo. Ngokomzekelo, incwadi ethi "Programming for Android» Brian Hardy. Kakade ke, lo kuphela umsebenzi olungileyo, kodwa into oko kuyimfuneko ukuze aqale. Nantsi uphengululo kwisixhobo kwaye ungaqala kwi indlela eya empumelelweni.
