Iilwimi eziBalaseleyo zokuCwangciswa kweNkqubo ye-Android

Kweli nqaku ndiza kukunika ulwazi kwezona lwimi zilungileyo zokucwangcisa iprogrammerung ye-android, kwaye kutheni iPython ingcono kuneJava. Ndiza kuthetha nge-Android Emulator Intel HAXM, elinye lamaqonga esoftware abalulekileyo kwiprogrammerung ye-android. Masiqalise. Ndiyathemba ukuba ulonwabele eli nqaku. Ukuba unemibuzo okanye izimvo malunga nenqaku, nceda ushiye uluvo. Ndingavuya ukubaphendula.

I-XML-Parsing Methode ye-XML-Daten createQuotesFromXMLString()

Ukusebenzisa i 'createQuotesFromXMLString()’ umsebenzi kwi C# inkqubo ukubuyisela kwaye ubonise idatha yokubhaliweyo ehambelanayo ilula. Ibuyisela uluhlu lwamangeno olumele isithuba ngasinye kwi-XML feed. Le ndlela iqhuba umtya weXML kwaye ibuyisela uluhlu lwamaxabiso okubhaliweyo ngendlela yophawulo lweHTML.

Kufuneka uqale ubize iklasi esebenzisa indlela yokwahlulahlula. Inxalenye yokuqala yale ndlela kukukhetha ukuba yeyiphi na imihlaba ofuna ukuyicazulula. Ukuba ukhetha i “ukungena” ithegi, umhlaluli uyakukhupha idatha yalethegi kunye naziphi iithegi ezibekwe kwindlwane. Inxalenye yesibini yeklasi, readFeed(), iqhuba ifayile ye-XML kwaye ibuyisela uLuhlu lwedatha ekhutshiweyo.

I-DOM API ibonelela ngendlela eqhelekileyo yokwahlulahlula amaxwebhu eXML. Le klasi ibonelela ngeeklasi kunye neendlela zokuhamba, inkqubo, kwaye ugcine uxwebhu. I-DOM API ibonelela ngee-APIs ezisemgangathweni ezidityanisiweyo ukukhohlisa iDOM, kuquka ukukwazi ukwenza imisebenzi yokukhangela kunye nokunqumla umthi woxwebhu. Kwizicelo ezisebenzisanayo, you can create an object model of an XML document using the DOM API.

Python is a better programming language for android programmierung

If you’re interested in developing Android applications, you may want to consider learning Python as a programming language. Python apps have higher memory consumption, but third-party tools can convert them to Android Packages. And because of the increasing demand for Android apps, it’s beneficial to know more than one programming language to ensure you’re working with the best possible solution. The following paragraphs will discuss some of the reasons why Python is a better programming language for Android application development.

It’s easy to learn Python, and its popularity is growing. Ngomnye, iibrendi ezininzi ezinkulu ezifana ne-Uber kunye neSpotify zisebenzisa ulwimi. Kwaye isetyenziswa ngokubanzi ngabaphuhlisi, nto leyo eyenza kube lula kwabaqalayo ukufunda. Ngaphaya koko, abaphuhlisi baya kukufumanisa kulula kakhulu ukwenza usetyenziso lwe-Android usebenzisa iPython kuba ivumela abaphuhlisi ukuba basebenzise iimodyuli ukulawula idatha enkulu.. Ngenxa yokuthandwa kwayo, I-python isiba lulwimi lwenkqubo oludumileyo kwiiapps ze-Android, ngakumbi kumashishini kunye nabaqalayo.

Enye inzuzo enkulu yePython kukuhambelana kwayo kakuhle. Inokusebenza kwiinkqubo ezininzi zokusebenza kunye namaqonga. Unokongeza kwaye ususe iimodyuli kunye nemisebenzi kamva ngaphandle kokuphinda ubhale usetyenziso. Kwaye iPython ikwabonelela ngokukwazi ukubhala iimvavanyo kunye nokubeka iliso kuyilo lweapp ngexesha lokwenyani. Esi sesinye sezizathu eziphambili zokuba kutheni iPython ithandwa ngakumbi phakathi kwabaphuhlisi. Kwaye okokugqibela kodwa kungancinci, kulula ukufunda kunye nokuhambisa.

Iinzuzo zePython phezu kweJava zininzi. I-Python kulula ukuyifunda, kwaye yenza ukhowudo ngokukhawuleza. I-Python nayo isebenza ngakumbi, kwaye inokukunceda uphuhlise usetyenziso oluphathwayo ngokukhawuleza kakhulu kuneJava. Nokuba ukhangela iqela lophuhliso lwe-Android, ungaqesha eyona programmer yepython ekhoyo ukukunceda wenze eyona app ifanelekileyo kubathengi bakho. Kwaye ngenxa yokuba abaphuhlisi be-Android bavame ukusebenzisa iPython ngaphezu kwezinye iilwimi, uya kuba neendlela ezininzi zokukhetha kuzo.

IJava lolona lwimi ludumileyo lwenkqubo ye-android programmierung

Ukuba ufuna ukufunda inkqubo ye-Android, kuya kufuneka ufunde iJava. Zininzi izinto eziluncedo kolu lwimi lwenkqubo, kodwa ineentsilelo zayo ngokunjalo. Eli nqaku lichaza ezinye zeenzuzo zeKotlin. Phezu kwayo nje imida yayo, IJava isetyenziswa kakhulu kwaye lolona lwimi lusetyenziswa kakhulu kwi-Android. Eli nqaku lichaza ezinye zeenzuzo kunye nokungalunganga. Ikwalukhetho oluhle lwenkqubo ye-Android ukuba ufuna ukubhala usetyenziso lwe-Android.

I-Kotlin lulwimi lwenkqubo oluvulelekileyo olusebenza kwiJava Virtual Machine. Kulula ukufunda kwaye inesintaksi esifutshane. Uninzi lwabaphuhlisi beapp ye-android bakhetha yona kwiJava ngenxa yokusebenziseka kwayo ngokulula kunye nokufikeleleka. Ikwanayo neempawu zokhuseleko ezomeleleyo kwaye i-cross-platform iyahambelana. I-Kotlin yenye indlela ethandwayo kwiJava yophuhliso lwe-Android. Isimahla, kulula ukuyisebenzisa, kunye cross-platform ehambelanayo.

IJava lolona lwimi ludumileyo lwenkqubo yophuhliso lwe-android, ke lukhetho oluhle ukuba ujonge ukuqalisa ngokukhawuleza. Nangona kunjalo, ukuba ujonge ulwimi ekulula ukulufunda kwaye lukhawuleza, C # lukhetho olulungileyo. I-C++ lolunye ulwimi lwenkqubo yeqonga, kwaye isetyenziselwa ukwenza imidlalo yeselula. Iilayibrari zayo zibonelela ngolawulo olungcono lweememori kunye nokuvuza kwememori okumbalwa kuneJava.

Inkqubo ye-Android kwiJava sisixhobo esihle kakhulu sokuqalisa abadwelisi benkqubo. Nangona kunjalo, IJava inokuba nzima kakhulu kubaqalayo, ngoko ke kungcono ukuba ufunde iilwimi zokuprograma eziphucukileyo. I-Kotlin lulwimi olunqamlezayo, kwaye isebenza kuMatshini weJava Virtual. Izibonelelo zokufunda i-Android ngeJava azibonakali nje. Uya kufunda ngakumbi ngolwimi, kodwa ufumane amava owadingayo ukuze uqalise ukwenza usetyenziso lwe-Android.

I-C# lulwimi lwenkqubo olujolise kwinto ephuhliswe nguMicrosoft. Lulwimi olujolise kwinto kwaye lusebenza kwiXesha lokuSebenza koLwimi oluQhelekileyo. Oku kuthetha ukuba isebenza kuwo onke amaqonga, kuquka Android. Ngolunye lolona khetho lubalaseleyo kubaphuhlisi be-Android, kodwa kufuna iminyaka yamava ukufunda ulwimi kakuhle. Nangona ukuthandwa kwayo, IJava lulwimi olunzima ukulufunda, kwaye ayizi nobutyebi obuninzi.

I-Android Emulator Intel HAXM liqonga lesoftware elibalulekileyo lenkqubo ye-android

Njengoko abaphuhlisi be-Android bafuna uphuculo ekusebenzeni kwe-emulator ye-Android, I-Intel ize nesisombululo. Umqhubi omtsha we-Intel HAXM wenzelwe ukuphucula ukusebenza kwe-emulator ye-Android ngokumangalisayo. Ngohlaziyo lwayo lwesithathu, iyakwazi ukuguqula iilaptops ezingasebenziyo zibe ziimeko ezisebenzayo zophuhliso. Qhubeka ufunde ukufumanisa ukuba ungasebenzisa njani ithuba lomqhubi omtsha.

Ungaqhuba i-emulator kwiPC ene-64-bit processor kunye nekhamera yewebhu ekwaziyo ukubamba izakhelo ezingama-720p.. Ezinye ii-emulators zikukhuthaza ukuba wenze i-hardware-acceleration, enokunyusa ukusebenza kwesixhobo esibonakalayo. Kwiinkqubo ze-Intel, Inguqulelo yeHAXM 7.2.0 Iyafuneka. Iinkqubo ze-AMD zifuna inkxaso ye-AMD-V kunye ne-Windows Hypervisor Platform API.

Xa usebenzisa i-emulator, kufuneka uqinisekise ukuba ixhasa iNqanaba le-API 17 kwaye ifakwe kumatshini wokusingatha. Kwiinkqubo zex86, I-HAXM ikwaxhasa ukulinganisa kwe-GPU. Ukulinganisa kweGPU, ngenye indlela eyaziwa ngokuba “Ukukhawuleza kweGPU”, isebenzisa i-GPU kumatshini wokubamba ukukhawulezisa isantya se-emulator. Ukuba ufuna i-emulator ekhawulezayo, Ukulinganisa kweGPU lukhetho olukhulu.

I-emulator ye-Android inokulinganisa isixhobo se-Android kwikhompyuter yakho kwaye ilingise bonke ubuchule bayo. Iyakwazi ukulinganisa yonke imiba yesixhobo kuquka iminxeba engenayo kunye nemiyalezo ebhaliweyo, Izantya zenethiwekhi, ukujikeleza, kunye nezinye izixhobo zoluvo zehardware. Oku kunokukhawulezisa kakhulu ukudluliselwa kwedatha. Unokusebenzisa i-emulator ukuvavanya i-app yakho kwimeko yokwenyani. Ukuba ne-emulator kukunika ithuba lokuzama isixhobo kumxholo ngaphandle kobunzima bokuguqula eyokwenyani..

Unokusebenzisa i-emulator ukurekhoda iaudio okanye ividiyo. Ngokutsala iifayile kwiscreen se-emulator, zibekwe kulawulo olubizwa ngokuba yi/sdcard/Download. Iifayile zinokujongwa ngesiXhobo soMhloli weFayile okanye iiFayile okanye uKhuphela usetyenziso kwisixhobo sakho. Ukuba awunayo ikhompyuter yokufaka i-Android Studio, ungaqhuba usetyenziso lwakho kwi-emulator endaweni yoko.
