Uma ungaqiniseki ukuthi uyifaka kanjani i-Eclipse, hlola iwebhusayithi yonjiniyela we-Android ukuze uthole imiyalelo yokufaka indawo yokuthuthukisa i-Java.

C++

Uma ungawazi umehluko phakathi kwe-Kotlin ne-C++, kunezindaba ezinhle kuwe: zombili ziphathwa kakhulu kuwo wonke amasistimu wokusebenza. I-syntax yekhodi ye-Kotlin iqondile, futhi ingahlanganiswa ibe ikhodi yomdabu noma i-JavaScript. NjengeJava, isebenza ku-Java Virtual Machine. Zombili ziyaphatheka kakhulu, futhi zombili izilimi zinikeza isethi efanayo yezinzuzo kanye nokubi.

As Android is distributed for a wide variety of devices, it’s vital to consider platform compatibility. Ideally, your C++ code will be compiled into a library that will run on all platforms. This is particularly important because 64-bit ABI support will become mandatory with the release of Android Pie. It’s also advisable to take advantage of the NDK when developing an Android app. Ngaphandle kwalokho, C++ code will also run without any noticeable differences during the app’s build and runtime.

Ngenhlanhla, many Android app development platforms support C/C++ code, and Android Studio allows you to run this code on the device directly. C++ code can improve performance, especially when developing 3D games. Ngaphezu kwalokho, it’s easier to integrate libraries written in C, making it more flexible than Java. Uma ungaqiniseki ukuthi iyiphi ekulungele, cabanga ukufunda C++. Kulula ukufunda, futhi kuyindlela enhle kubo bobabili abaqalayo nabathuthukisi abathuthukile.

I-Python

Uzothola izinzuzo ezithile zokusebenzisa i-Python yokuthuthukiswa kohlelo lokusebenza lwe-Android. Lolu limi lokuhlela luza ne-debugger engakusiza ukuthi uhlole amaphutha kukhodi yakho.

I-XML

I-XML yokuthuthukisa uhlelo lokusebenza lwe-Android inezinzuzo ezimbalwa. I-XML ilula, kulula ukufaka ikhodi, futhi ingasetshenziswa ukuchaza idatha ehlobene ne-UI. Lesi sihloko sizonikeza isingeniso esifushane sokusetshenziswa kwe-XML kuzinhlelo zokusebenza zeselula. Ungafunda futhi indlela yokusebenzisa i-XML kuphrojekthi yakho yokuthuthukisa i-Android. Izinzuzo zayo kuxoxwa ngazo ngezansi. Uma ufuna ukuqala ukuthuthukisa izinhlelo zokusebenza ze-Android ngokushesha, I-XML iyindlela engcono kakhulu yokuhamba.

I-XML iwulimi lwemakhaphu olwakhe lwaklanywa ukuthi luphathe futhi luhlele idatha. Ukugxila kwayo kudatha esikhundleni sokuhlela kuyenze yaba indinganiso edumile ye-cross-platform. Nakuba kungelona ulimi lohlelo, I-XML iyinketho eqinile yokushintshanisa kanambambili nombhalo. Kubalulekile ukukhumbula ukuthi amafayela e-XML ngokuvamile afakwe ikhodi ku-UTF-8, ngakho-ke qiniseka ukuthi awubeki i-XML endaweni enezisetshenziswa ezifana ne-Android.

Izakhiwo zezinhlelo zokusebenza ze-Android zibhalwe nge-XML. Bacacisa ukwakheka kwesixhumi esibonakalayo somsebenzisi. Amafayela esakhiwo kufanele abe nesici esiyimpande esibizwa ngokuthi ukubuka. Ukubuka kumelela into eyakhelwe ngaphakathi. Isigaba esingaphansi sekilasi lokubuka sibizwa nge-ViewGroup. Lokhu kubuka kungaqoqwa ndawonye ngamafayela ako e-XML. I-ViewGroup iyisigaba esiyisisekelo sazo zonke izakhiwo kanye neziqukathi zokubuka.

Umphathi wezaziso

Kunezici ezimbili eziyinhloko zesiphathi Sezaziso zokuthuthukiswa kohlelo lokusebenza lwe-Android. Enye ikhono lokufingqa izaziso eziningi. Lesi sici sitholakalela izinhlelo zokusebenza zokuthumela imiyalezo ezibonisa uhlu lwemilayezo yazo yakamuva. Notifications can be summarized by adding a single message to the group. If there are multiple messages, the first one will be displayed and the other ones will not. The second feature is the ability to set a rate limit for the notifications. If they are updated too frequently, Android may even drop the notifications.

While it is not essential for you to use this feature for your Android app development, it is an excellent way to keep your users updated. Notifications are useful for luring users into opening an app and catching their attention. Nokho, a notification must be as simple as an icon, as most Android users are busy and do not have time to read lengthy text. This is why you should use an icon to make the notification more compelling for users.

When creating your notifications, kufanele uqiniseke ukuthi usebenzisa isistimu yezaziso ukuze uqinisekise ukulethwa okufanele. Izaziso ziyingxenye ebalulekile yohlelo lokusebenza lwe-Android, futhi kufanele ihlolwe kahle. Izaziso zazisa abasebenzisi ngolwazi olubalulekile, bahlale benolwazi ngezenzakalo ezizayo, futhi ubavimbele ukuthi bangaphuthelwa ama-aphoyintimenti. Ngenkathi iyunithi yokuhlola i-UI yohlelo lokusebenza lwe-Android kuyisiqalo esihle kakhulu, ayanele futhi izohluleka kuphela uma ungazihloli kahle izaziso.

Ingxenye yomsebenzi

Ingxenye yomsebenzi ekuthuthukisweni kohlelo lokusebenza lwe-Android iqukethe into esebenza ocingweni. Isebenza kuphrosesa yefoni futhi ingasetshenziswa ukwenza imisebenzi eyahlukene. Ngokungafani nezinye izinto, ingavulwa futhi ivalwe ngumsebenzisi. Kuye ngohlobo lwedivayisi, I-Android isebenzisa izindlela ezihlukile zokuvula nokuvala umsebenzi. Enye yalezi zindlela ibizwa nge-Start(). Uma le ndlela isibiziwe, umsebenzi ungabonakala noma ufihlwe.

Isigaba somsebenzi siyisisekelo kuzinhlelo zokusebenza ze-Android futhi siyingxenye ebalulekile yemodeli. Imisebenzi ingamawindi lapho uhlelo lokusebenza lungadonsa ukusebenzelana komsebenzisi. Ngokuvamile zigxile esikrinini, kodwa ingaba ncane kunesikrini noma ibonakale intanta phezu kwamanye amawindi. Isigaba somsebenzi owodwa sivamise ukusebenzisa isikrini esisodwa. Nokho, kukhona okuhlukile okumbalwa okuphawulekayo kulo mthetho. Uma ungaqiniseki ukuthi umsebenzi uyingxenye efanele yohlelo lwakho lokusebenza, ungabheka imibhalo ye-Android.

Uma umsebenzi uqalwa, isistimu ye-Android iqala inqubo yohlelo lokusebenza efanele. Le ngxenye izophinde iqinisekise noma yimaphi amakilasi adingekayo. Le nqubo ivumela uhlelo lwakho lokusebenza ukuthi lugxume lisuka kwelinye ikhasi lewebhu liye kwelinye, futhi ushintshe phakathi kwezinhlelo zokusebenza uma kunesidingo. Ngokwesibonelo, ungavula ulwazi loxhumana naye kwelinye uhlelo lokusebenza bese ubhala umlayezo kolunye. Ngokufanayo, ungashintshela kolunye uhlelo lokusebenza phakathi futhi uqalise kabusha umsebenzi ofanayo.
