Maitiro ekugadzira Android maapuro neJava, Kotlin, C++, uye Snapseed

Kana iwe wakambozvibvunza kuti ungagadzira sei Android app, mhinduro ndeyokutanga neJava kana Kotlin. Iwe unozodawo ruzivo rwakanaka rweC ++ kana Snapseed. Kana iwe usingazive chero ipi yemitauro iyi, usanetseke – isu tichatsanangura zvakakosha. Kana wangoziva zvekutanga, unogona kutanga kuvaka maapplication uye kutaurirana navo pane chako kifaa! Shure kwezvose, unongova mushandisiwo zvake, rudyi?

Java

Iwe wakambonzwa nezve Android, asi unogona kunge usiri kujairana neJava apps. Kugadzira nharembozha dzepuratifomu yeAroid chiitiko chakajairika pakati pevazhinji vanogadzira. Android Studio ndiyo inotungamira Android kuvandudza chishandiso uye inouya neakawanda akasiyana-siyana emaraibhurari ane simba ekodhi, kusanganisira Java tutorials. Iinewo chikamu chakakura chezvinyorwa, uye unogona kutanga nemavhidhiyo edzidziso nekukurumidza. Asi iwe unofanirwawo kuve neruzivo rweJava kuita kuti maitiro acho anakidze uye abudirire.

Kana iwe usina chokwadi chekutangira kana zvasvika pakudzidza Java, iwe ungangoda kurodha imwe yemahara tutorials. Zvidzidzo zvezvirongwa izvi zvinowanzobatsira zvakanyanya uye zviri nyore kutevera. Avo vasingazive zvakawanda nezveJava vanofanira kutanga neEnki. Iyo inokutendera iwe kuti udzidze izvo zvekutanga zveJava kuvandudza uye kuishandisa muhupenyu chaihwo. Dcoder uye DroidEdit ndiwo maviri akanakisa Java IDE eAroid. Ose ari maviri anotendera iwe kugadzirisa kodhi zvakananga kubva kune yako smartphone, kuvaita chishandiso chakakwana chevanotanga.

Nepo Android isiri iyo puratifomu yakakwana kune ese marudzi emugadziri, Java inoramba iri iyo inonyanya kufarirwa mitauro yemafoni. Vazhinji vanogadzira nyanzvi vanoshandisa Java kugadzira maapplication avo. Iyo Android papuratifomu inotakurika uye kujairana nemutauro wechirongwa uyu inoita kuti ive sarudzo yakanaka kune chero munhu ari kuvandudza nharembozha. Zvisinei, usati waita sarudzo yekuchinja kuenda kuAndroid, iwe unofanirwa kufunga nezvemusika wako waunoda. Pane zvakawanda zvakanakira kushandisa Java yekuvandudza Android. Kana iwe uri kuronga kugadzira pasi rose app, Java ndiyo yakanyanya kufanirwa sarudzo.

IDE yakanaka yeAroid yakakosha pakuita shuwa kuti kodhi yako inounganidza nemazvo. JStudio ine zvakawanda zvinobatsira, kusanganisira auto-kupedzisa uye kodhi-kupedzisa maficha. Kunze kwaizvozvo, ine terminal yakavakirwa-mukati, iyo inokutendera kuti uite mirairo ine hukama ne Android. Pamusoro pe, inokubatsira kubata mafaera ejava, Kopira uye unama kodhi, uye kunyange kuita chaiyo-nguva yekukanganisa kutarisa. Izvi zvinoita kuti kuvandudzwa kweJava pa Android kuve nemhepo.

Kotlin

Java ndiyo mutauro wekare wekugadzira, uye ichiri kutonga nyika yekusimudzira app. Kugona kwayo kwepamusoro-soro kwekunyora kunoita kuti ive sarudzo yakanaka kune vakawanda vanogadzira, asi ine zvimhingamupinyi zvayo. Mumakore achangopfuura, kuvandudzwa kweAroid apps kwave kuda kushandiswa kwemutauro mutsva wekukodha. Kotlin yeAroid apps mumwe mutauro wakadaro. Nechiziviso chazvino kubva kuGoogle, Kotlin ikozvino mutauro unosarurwa wekugadzira Android apps.

Kunyange zvazvo Kotlin syntax yakafanana neJava, pane zvimwe zvakasiyana zvakasiyana pakati peJava neKotlin. Zvekutanga, Kotlin inotsigira ese ari maviri maitiro uye anonangana nechirongwa. Inotaipa statically, zvinoreva kuti marudzi e data anogona kutsanangurwa nenzira mbiri dzakasiyana: isingashanduke uye isingabatike. Iyo yekupedzisira inobatsira kuchengetedza yako Android app's codebase. Iwe unogonawo kugadzira makirasi ekushandisa zvakare uye zvikamu muKotlin nekushandisa purojekiti wizard.

Imwe misiyano pakati peJava neKotlin ndiyo nzira yekuwedzera. Nepo Java ichipa API yekuwedzera makirasi aripo, Kotlin inoita kuti uwedzere zita rekirasi kune zita rebasa. MuJava, unofanira kugara nhaka kirasi yevabereki’ mabasa. Asi muKotlin, iwe unogona kuwedzera rako pachako zita rekuita uye kugara nhaka imwechete kirasi's API. Nenzira iyi, unogona kuwedzera kushanda kwekirasi yako pasina kugadzirisa chimiro kana kodhi.

Sezvakaita chero mutauro mutsva, kudzidza Kotlin hakusi nyore. Pane zvimwe zvinhu zvaunofanira kuziva usati wazviita muprojekiti yako. Kana iwe usati wagadzirira iyo yekudzidza curve, zviri nani kunamatira kune yakajairika programming mutauro seJava. Kunyange zvazvo zvingava zvakaoma kune vanotanga, ndiyo sarudzo yakakwana kune vane ruzivo Android Developers. Mutauro wacho uri nyore kudzidza uye kukwenenzvera nzira yekuvandudza yetsika Android apps.

Nepo Java iri nyore kudzidza uye zvakanyanya kujaira kune vanogadzira, haina kupa maitiro akafanana neKotlin. Semuyenzaniso, Java haitsigire coroutines, inova purogiramu yemuenzaniso inobvumira tambo dzakawanda kugadzirwa panguva imwe chete. Kushandisa tambo dzakawanda kunowedzera saizi yecodebase uye kunogona kukonzera kukanganisa. Pamusoro pe, Vagadziri veJava vanofanirwa kuongorora nemaoko marudzi akasiyana uye voakanda zvichienderana nevashandisi vavo. Kotlin inopa yakangwara compiler iyo inotsiva yakasarudzika makanda ane yakagadzikana tsika.

C++

Kana iwe uchida kugadzira Android app, iwe unofanirwa kuziva kuti C ++ ine akati wandei mabhenefiti pamusoro peJava. Izvi zvinodaro nekuti C++ inokurumidza zvakanyanya pamaalgorithms anosanganisira akawanda akasiyana. Zvakare, kana iwe ukaronga kushandisa iyo app kugadzira injini dzemitambo kana CPU-yakanyanya maapplication, Iwe unofanirwa kufunga nezve kushandisa C ++. Java ine zvipingamupinyi zvakawanda, saka unofanira kudzidza Java usati waenda paC++. Ichi chinyorwa chichatsanangura zvakanakira C ++ yekuvandudza Android.

Java mutauro wakanaka wekugadzira, asi C ++ ine zvakawanda zvakanaka. Inoshanduka uye inotora ndangariro shoma pane Java, uye zviri nyore kuenzanisa software yakasiyana. C++ zvakare inokurumidza kupfuura Java, saka unozokwanisa kuwana tsikidzi zviri nyore. Zvisinei, C ++ haina yakajairwa mushandisi interface seJava. C ++ inogona kushandiswa kumabasa akaomarara, asi haina maitiro akawanda. C ++ zvakare yakaoma kupfuura Java, saka unofanira kuziva kusiyana uku usati wafunga kuti woshandisa papi.

Kugadzira chirongwa chitsva, vhura iyo IDE. Famba uchienda kuProjekti pane kuruboshwe rweIDE. Kubva pane yekudonha-pasi menyu, sarudza dhairekitori idzva kana C ++ sosi faira. Dzvanya iyo Type yekudonha-pasi menyu kuti usarudze faira rekuwedzera. Iwe unogona ipapo kushandisa Customize C ++ Tsigiro bhatani kuti uwedzere mamwe mafaera kupurojekiti. Neimwe nzira, unogona kugadzira chirongwa chitsva uye wochisarudza se'Native C++’ rudzi rweprojekiti.

Imwe mitauro yakakurumbira yekugadzira Android iJava. Uyu ndiwo mutauro wekare uye unonyanya kushandiswa hurongwa uye uchiri kufarirwa nekuda kweraibhurari yayo yakakura uye kugona-kuunganidza.. Kotlin inzira yakakurumbira kune Java. Mutauro wemuchinjika-chikuva uye unokurumidza zvakakwana kune nharembozha. Iyo zvakare inoburitsa madiki executables. Pasinei nekuoma kwayo, Java isarudzo huru kune Android app Developers.

Snapseed

Kana iwe uchitsvaga app yekuvandudza mafoto ako, Snapseed ndiyo sarudzo chaiyo. Ichi chishandiso chinokupa iwe kugona kushandisa mafirita edhijitari uye kuwedzera mafoto ako.
