Kana iwe uri mutsva zvachose kune iyi ndima, zvakakodzera kutora maminetsi mashoma kuverenga pamusoro pezvimwe zvekutanga kutanga. Verenga pamusoro paJava, Zvinangwa, ShareActionProvider, uye XML-Parsing Methode.

Java

Kugadzira Android app hakufanirwe kuve kwakaoma – kune akati wandei maturusi aripo ayo achakubatsira iwe kugadzira application nekukurumidza uye nyore. Chekutanga, unofanira kudhawunirodha yakakodzera coding software. Next, isa Java uye nzvimbo yekuvandudza app, senge Android Studio. Izvi zvinokutendera iwe kugadzira app pasina nguva. Iwe zvakare unozoda kutsanangura chimiro cheapp uye dhizaini. Mushure meizvi, iwe unogona kusarudza iyo interface dhizaini.

Iwe unogona zvakare kusarudza iyo Android app yekuvandudza kit. Aya makiti akanakira vanotanga vanogadzira uye anouya neakasiyana ezvidzidzo uye zvekushandisa. Paunenge watora iyo SDK, unogona kutanga kugadzira uye kuronga yako yekutanga Android app. Iyo Android SDK inofanirwa kune vanotanga, uye kune zvakawanda zvemahara zvepamhepo zviwanikwa zviripo, kusanganisira dzakasiyana siyana Tutorials, text, uye vhidhiyo mienzaniso. Kana iwe uri mutsva kuprogramming, iwe unogona zvakare kujoina CHIP Forum, kwaunogona kubvunza mibvunzo uye kuchinjana matipi nevamwe vane ruzivo vanogadzira zvirongwa.

Iyo Android Online Kurs inopa yakadzama sumo yekuvandudza app Android, kuvhara zvese zvinodiwa kuti ugadzire app nyanzvi. Munyori anokufambisa nenzira yebudiriro nhanho-nhanho, uye inotsanangura akanyanya kukosha maficha ekukodha inyanzvi Android app. Rugwaro rwunokudzidzisawo mashandisiro aungaita Android Studio uye mamwe maturusi akawanda. Iwe zvakare unozodzidza maitiro ekuronga mapurogiramu ane akawanda skrini, kumashure maitiro, nezvimwe zvakawanda.

Zvinangwa

Kana iwe uchida kuronga yako Android apps kuti upindure kune chinangwa, iwe unogona kushandisa iyo Android's intent programmierung framework. Zvinangwa zvinogona kushandiswa kukonzeresa zviito uye kutumira ruzivo kune server. Iyo Android intent programmierung framework inopa nzira dzinoverengeka dzekuita izvi. Imwe yenzira idzi ndeyekushandisa Google Mepu.

Zvinangwa ndiwo hwaro hwemazhinji maapplication eAroid. Vanobvumira mapurogiramu ako kuti ataure nemamwe mapurogiramu, zvikamu, nemidziyo. Iwo anogona zvakare kushandiswa kufamba mukati mekushandisa, senge kana mushandisi agamuchira chinongedzo chekubhadhara muSMS yavo. Ichi chimiro chinoita kuti zvikwanise kupfuudza ruzivo kubva kune imwe app kuenda kune imwe, kunyange kubva kune imwechete application.

Zvinangwa zvinotendera yako Android maapuro kutumira data kune mamwe maapplication, zvakadai semafaira. Iwe unogona zvakare kukumbira kuti maapplication ako avhure faira kubva kune imwe app. Kuita izvi, unofanira kutsanangura mhando yeMIME uye URI nzvimbo. Neimwe nzira, unogona kukumbira kugadzira gwaro idzva. Chero bedzi iyo faira ichitungamirirwa neimwe app, yako Android apps inogona kutumira data kunzvimbo iyoyo. Iyo data inotumirwa kune server uchishandisa URI.

Zvinangwa zvinoshandiswa muAroid apps kuita mabasa akasiyana-siyana kumashure. Iwo anobatsira kana iwe uchida kutanga-imwe-nguva basa uye usingade mushandisi kusangana. Zvinangwa zvinogona kupfuudzwa kune yekutangaService() nzira yeapp yako. Zvinangwa zvinogonawo kushandiswa kutumira mameseji kune mamwe maapplication. Semuyenzaniso, Chinangwa chinogona kushandiswa kuudza imwe app kuti faira rapedza kurodha uye ragadzirira kushandiswa. Zvinangwa zvinogonawo kushandiswa mukubatana, nerubatsiro rweBroadcast Receivers.

ShareActionProvider

Kana iwe uchida kugovera zvirimo pakati peako Android apps, unogona kushandisa ShareActionProvider. Inoshanda nekuratidza runyoro rwekugovera maapplication pachiratidziri. Kana mushandisi adzvanya pane icon yeapp, iyo ShareActionProvider ichaitwa.

Iyi iwijeti yakapusa asi ine simba inochengeta maitiro uye chitarisiko chako. Zvese zvaunoda kuti uite kudoma zita reiyo share target. Iyo ShareActionProvider inochengetedza chiyero chezvinangwa zvekugova uye icharatidza inonyanya kufarirwa yekugovera mubhawa yeapp..

Ichi chishandiso chakanakira vanotanga kuronga Android apps. Nechokushandisa ichi, iwe unogona kubatanidza yako Android app kune REST yakanangana newebhu service. Izvi zvinonyanya kukosha kana uchiratidza data. Zvishandiso zvefoni zvinogadzira kukosha kwepamusoro kana zvichiratidza data. Zvisinei, iyo data haina kuchengetwa pamudziyo pachayo – pachinzvimbo, inotorwa kubva kumawebhusaiti akasiyana panguva yekumhanya kweapp.

Iwe unofanirwa kuve neruzivo rweJava kana iwe uchida kugadzira Android application. Unogona kudhawunirodha Android Studio, yakavhurika-sosi yekuvandudza nharaunda neGoogle. Pane zvakawanda zvinyorwa uye mavhidhiyo pamhepo ekukubatsira kuti utange. Iwe unogona zvakare kujoina CHIP foramu yekutsinhana mazano nevamwe vanogadzira.

XML-Parsing Methode

XML-Parsing chikamu chakakosha cheAroid apps programming. Iri ibasa rakajairika nekuti mawebhusaiti mazhinji uye mapuratifomu ekubloga anoshandisa iyo XML fomati yekugovana ruzivo. Zvishandiso zveAroid zvinoda kuziva mashandisiro e data iyi mukushandisa kwavo, uye nzira iyi inoshanda. Zvinotora data kubva kune chinyorwa faira uye inoigadzirisa uchishandisa nzira yakatarisana nechinhu. Kune matatu marudzi eXML parsers mu Android. Inonyanya kushandiswa ndeye XMLPullParser. Zviri nyore kushandisa uye zvinobudirira.

Iyo app yemuenzaniso inodhiza ma tag anested senge zita, link, uye pfupiso. Iyo ine zvakare nzira inonzi skip(). Iyi nzira inoburitsa musoro, link, uye pfupiso kubva pagwaro reXML. Inobva yadzokorodza iyo feed uye inodzosera Rondedzero yezvinyorwa. Kana kukanganisa kukaitika panguva yekupatsanura, iyo app ichaita kusarudzika.

Nhanho yekutanga pakudzidza mashandisiro eXML-Parsing Methode muAroid apps programming kumisa nharaunda yako. Android Studio inodiwa pakumhanyisa kodhi yemuenzaniso. Haufanire kushandisa yazvino vhezheni yeAndroid SDK API. Yekutanga XML uye JSON parsing yanga iripo kubva pamazuva ekutanga eAroid.

XML data

Iwe wakambonzwa nezve XML-Daten, uye ungangoda kudzidza kuronga navo kuita kuti maapplication ako eAroid awedzere kunakidza. XML mutauro wemakapu unowanzo shandiswa pakuchinjana data pakati pemakomputa nemaapplication, sezvakaita mumawebhusaiti. Yako Android application ichakwanisa kuverenga nekunyora aya data nenzira yeXML-tambo, izvo zvinofanirwa kupatsanurwa kuti zvidudzirwe.

XML-Daten ndiyo hwaro hweXML-based programming, uye dzinoshandiswa kune zvakasiyana siyana zvinangwa. Mutauro une curve yekudzidza yakaderera uye iri nyore kushandisa kune dzakasiyana siyana dzekushandisa. Iyo zvakare iri nyore fomati yekunzwisisa, uye iwe unogona kuwana mienzaniso yakawanda online. Unogona kudhawunirodha mafaera eXML uye woavhura mune mameseji edhita yeAroid.

Unogona kuverenga XML-Daten yeAroid apps nekutsanangura zita repasuru yeapp yako uye peji rekutanga. Iwe unogona zvakare kutsanangura akasiyana zviitiko uye zvinhu zveapp yako.

Native Apps vs Progressive Web Apps

Kune akawanda mabhenefiti ekugadzira PWA pachinzvimbo cheyakaberekerwa app yeAroid. Nokuda kwechinhu chimwe, PWAs inogona kudhura zvakanyanya pane yemuno maapps. Zvakare, PWAs inogona kuenderana nemidziyo yese. Nepo maapuro emuno anofanirwa kuve akagadziridzwa kuti akwane akasiyana siyana skrini, PWAs dzakagadzirirwa kushanda pane chero mudziyo.

Nepo zvemuno maapplication ari kudhura kugadzira, maapplication ewebhu anofambira mberi anokurumidza. Aya maapplication anoshandisa HTML, CSS, uye JavaScript kugadzira application. Zvisinei, vanopa mashandiro mashoma, sekutadza kuwana makarenda, contacts, browser mabhukumaki, uye Bluetooth.

Pasinei nezvipingamupinyi izvi, inofambira mberi yewebhu maapplication anogona kutora mukana wemaitiro emudziyo. Kusiyana neakare maapuro, inofambira mberi yewebhu maapplication anogona kuwana ese maficha emudziyo, kusanganisira kamera, kambasi, uye contact list. Izvi zvinhu zvinogona kukubatsira kusarudza kuti ndeipi yekushandisa uye kana yakakodzera nguva yako yekudyara mukusimudzira.

Progressive web apps inogona kutumira uye kugamuchira zviziviso zvepush uye kuita kunze kwenyika. Pamusoro pe, vanogona kuvakwa pane chero system yekushandisa. Aya mawebhusaiti akanakira kuendesa zvirimo kumushandisi wenhare.

Kugadzira chirongwa cheAndroid Studio

Iwe unogona zvakare kusarudza iyo shoma SDK inodiwa kuvaka yako app. Iwe unozofanirwa kuwedzera mamwe mafaera kuprojekiti.

Mapurojekiti eAroid ane maforodha akasiyana uye mafaera ezvinangwa zvakasiyana. Kuwedzera kune iyo kodhi kodhi yekushandisa yako, anewo maraibhurari. Iyo libs folda inobata mamwe mafaera ejagi anodiwa nenguva yekushandisa. Iyo assets folda ine zvinhu zvinodhirowa uye static mafaera. Pakupedzisira, iyo gen/ folda ine sosi kodhi inogadzirwa ne Android's kuvaka maturusi.
