Maitiro ekutanga mu Android App Programming

Saka iwe unoda kugadzira Android app, asi hauzive pekutangira? Heano mazano mashoma ekukubatsira kuti utange. MIT App Inventor, Java-Code, Kukweva-uye-kudonhedza, uye DroidDraw ese makuru sarudzo. Besides, zvishandiso izvi ndezvemahara! Asi kana iwe usina purogiramu yekumashure, zvichiri kukosha kutarisa zvirongwa izvi – vanogona kuita kuti hurongwa hwose huve nyore.

MIT App Inventor

Kana iwe uri kufunga kushandisa MIT App Inventor kudzidza maitiro ekugadzira maapplication eAroid zvishandiso, wauya panzvimbo chaipo. Iyi nharaunda yekusimudzira yakabatanidzwa yewebhu maapplication yakatanga kupihwa neGoogle, asi ikozvino yakachengetedzwa neMassachusetts Institute of Technology. Unogona kudhawunirodha MIT App Inventor yemahara uye wotanga kugadzira maapplication nhasi. Heano mamwe mabhenefiti ekushandisa chishandiso ichi cheAroid app programming:

MIT's App Inventor chikuva chakavakirwa kutenderedza mutauro wakavakirwa-block, iyo inobvumira vanogadzira kugadzira uye kushandisazve kodhi uye zvikamu. Raibhurari ine mabasa ekutanga emitauro yekuronga, kusanganisira tambo, nhamba, uye mazita, pamwe neBooleans, masvomhu vanoshanda, nezvimwe. Aya mabhuroki anobvumira vanogadzira kupindura kune zviitiko zvehurongwa, kupindirana nemidziyo yemidziyo, uye gadzirisa zvinoonekwa. Sezvakaita chero nharaunda yepurogiramu, zvakakosha kuve nehwaro hwakasimba mukuvandudza kweapp usati waenda kune mamwe mapuratifomu.

Vadzidzi vane rusununguko rwakawanda rwekugadzira neApp Inventor nekuti vanogona kugadzira maapplication emafoni efoni, kunze kwechinyakare makomputa labs. Inobatsirawo vadzidzi kuti vazvione sevagadziri vedhijitari uye vave nhengo dzakasimba dzenharaunda dzavanogara. MIT yanga ichishanda neMIT kwemakore akawanda uye yaita kuti zvive nyore kune vadzidzisi kupa vadzidzi maturusi avanoda kuti vabudirire mubasa ravo.. Kune huwandu hwakasiyana hwekushandisa kweMIT App Inventor.

DroidDraw

Kune vanogadzira vanoda kunyora Android application, DroidDraw chishandiso chikuru chebasa iri. DroidDraw inopa graphical dhizaini edhita iyo inokutendera iwe kudhonza zvinhu zvakasiyana-siyana paUI yekushandisa.. Iwe unogona kutogadzirisa zvivakwa zvezvinhu izvi uchishandisa mahwindo emidziyo akapihwa neDroidDraw. Kana iwe uchitsvaga yemahara uye yakavhurika-sosi Android app yekuvandudza software, DroidDraw ndiyo yako yakanakisa kubheja.

Java-Code

Kune akawanda mabhenefiti uye kuipa kwekushandisa Java-Code yeAroid app programming. Inodzikamisa kushanduka kwemugadziri, asi inogona kubatsira kune nyore maapplication. Kana iwe uchida kugadzirisa iyo app, zvisinei, iwe unozofanirwa kuziva imwe Java-Code uye kuve nehumwe hunyanzvi hwekuziva. Kazhinji, vanamuzvinabhizinesi vanozohaya nyanzvi dzeApp Developers kuti dzibate iyo purojekiti kwavari. Verenga kuti udzidze kuti sei nzira iyi isingachinjiki uye yekudzivisa.

Java ndiyo mutauro wepurogiramu iyo yakawanda Android-Apps yakavakirwa pairi. Pane nzira dzakawanda dzekudzidza Java, kubva kumabhuku akajairwa kuenda kunzvimbo yekuvaka-app, Sravana Sameeralu Serial 4th Android Studio. Kana iwe uchangotanga, pane zvakawanda zvekubatsira online zviripo. Kune akawanda tutorials uye zvinyorwa, pamwe neCHIP forum kwaunogona kukurukura mibvunzo yako uye kuwana rubatsiro kubva kune vane ruzivo programmers. Iyo CHIP Forum inzvimbo yakanaka yekuwedzera rubatsiro zvakare.

Kusiyana neIDE yeIOS, Android-App-Programmierung neJava ichakudzidzisa zvese zvikamu zvinoumba nyanzvi app. Izvi zvinosanganisira nheyo yepasi, Android-Binding, uye otomatiki bvunzo. Uyezve, iwe uchadzidza kushandisa iyo Android-Framework nemidziyo yayo, pamwe nekubatanidza iyo SQLite dhatabhesi mune yako application. Neruzivo urwu, unogona kutanga kuvaka yako pachako nyanzvi maapplication uye wotanga kuwana imwe mari yekuwedzera.

Kukweva-uye-kudonhedza

Iwe unogona kugadzira kudhonza-uye-kudonhedza mapurogiramu eAroid nekushandisa dhizaini nekudonhedza chimiro. Dhova uye udonhedze mashandiro anokubatsira kufambisa data kubva kune imwe View kuenda kune imwe. Kuti udzidze zvakawanda, tarisa iyo Android Animations vhidhiyo kosi. Zvadaro, gadzira app uye woiedza kuti uone kana inoshanda sezvaitarisirwa. Iwe unozodzidza zvakare kugadzira kudhonza-uye-kudonhedza UI zvinhu. Mushure mekugadzira iyo yakakosha yekudhonza-uye-kudonha UI zvinhu, unogona kuenderera mberi kune mamwe emhando yepamusoro ekukwevera-uye-kudonha matekiniki.

Paunenge wagadzira muteereri wechiitiko chekudhonza, unogona kugamuchira data kubva chiitiko. Iwe unogona kupfuura mune data kuti iratidzwe kune mushandisi kuburikidza nemetadata. Iyo sisitimu inotumira iyo data kune callback nzira kana chinhu chekuteerera. Kana iyo data isiri iyo, nzira yacho ichadzoka 0 pachinzvimbo cheukoshi hwapfuura. Kana chiitiko chekudhonza chikabudirira, iwe uchagamuchira kukosha kwe boolean.

Kuwedzera kuita kwekudhonza kuapp yako, iwe unofanirwa kuve nechokwadi chekuti kodhi yako inoenderana nekudhonza uye kudonhedza protocol. Kana iwe usinganzwisise Android's Drag and Drop API, verenga zvinyorwa pane kudhonza uye kudonhedza chimiro paGitHub. Iwe uchawana wakakwana muenzaniso wekudhonza uye kudonhedza chimiro ipapo. Kana wapedza izvozvo, unogona kutanga kunyora yako yekudhonza-uye-kudonhedza Android app.

Internet-Services

Kana iwe uri kufunga kugadzira yako yekutanga mobile app, unenge uchinetseka kuti ungabatanidza sei Internet-Services mukushandisa kwako. Ichi chinyorwa chichakubatsira kuti utange. Munyaya ino, isu tichavhara maitiro ekumisikidza Android app yemakore masevhisi, uye kukupa mamwe matipi ekushandisa Internet-Services muapp yako. Kana usina chokwadi pekutangira, isu tichavhara izvo zvekutanga mu Android app programmieren.

MIT App Shamwari

Kana iwe uchida kudzidza izvo zvekutanga zveAroid app programming, iyo MIT App Shamwari yeAI2 chishandiso chakanakisa chekudzidza izvo zvekutanga. Iyi purogiramu inokubvumira kuti ugadzire mapurogiramu eAroid pakombuta uye uvaedze pane Android device. Unogona kubatanidza App Inventor kukombiyuta yako uchishandisa USB connection kana WiFi connection. Iyo purogiramu zvakare ine emulator pakombuta yako inotevedzera mudziyo wemushandisi.

Kushandisa App Mufambidzani we Android, iwe chekutanga unofanirwa kudhawunirodha uye kuisa iyo Companion app pane chako kifaa. Paunenge uine iyi app, vhura App Inventor uye tinya pane Project tab. Ita shuwa kuti zvishandiso zviviri izvi zviri pane imwecheteyo Wi-Fi network. Next, vhura purojekiti muApp Inventor uye sarudza “Batanidza kune Shamwari” kubva kumusoro menyu. Kana chirongwa chako chavhurwa, unogona kutanga programming.

Kuti uedze iyo app yawakagadzira, dhawunirodha iyo MIT App Inventor application. Iyo ine dhizaini yedhizaini iyo inokutendera iwe kudhonza nekudonhedza zvinhu kugadzira app. Iyo inosanganisirawo mabhuraki edhita iyo inobvumidza iwe kukodha logic zvinoonekwa. Paunenge wapedza app yako, unogona kushandisa App Inventor Companion kuti uiedze munyika chaiyo pane Android device. Kana iwe uchida kudzidza zvakawanda nezve MIT App Shamwari, tarisa wongororo yedu.
