Sinau Cara Pemrograman Aplikasi Android

Sadurunge miwiti sinau kode aplikasi Android, kudu sinau basa Jawa dhisik, Tujuan-C, utawa Swift. Sawise sampeyan wis kenal karo dhasar, sampeyan bisa nerusake menyang topik sing luwih rumit kayata ShareActionProvider. Artikel iki bakal nerangake unsur paling penting saka aplikasi Android. cara iki, sampeyan bisa nggawe aplikasi Highly fungsi lan pasar kanggo pelanggan. Sampeyan uga bisa sinau babagan ShareActionProvider, fitur paling penting saka sembarang app Android.

Jawa

Sinau babagan program aplikasi Android relatif gampang – yen ngerti basa Jawa. Nanging, yen sampeyan ora yakin carane kode, sampeyan bisa nemokake buku karo introduksi ing basa sing bisa mbantu miwiti. Buku iki nyakup macem-macem topik, kalebu pangembangan Android, kalebu kerangka Android, dhasar basa Jawa, lan liyane. The book is designed to help you create an application in a matter of days – you don’t even need to have a previous programming knowledge.

Before you begin learning Java, it is essential to understand the basics of Object-Oriented Programming. Yen wis ngerti basa Jawa, you can get a Java-Kurs to learn more about the language or to refresh your existing knowledge. Android app development uses Android Studio, which is an application development environment. There are also a wide range of videos and texts online, as well as forums such as CHIP, where you can ask questions and exchange ideas with experienced developers.

You can also learn more about cross-platform app development and DevOps by studying the Android Framework. The Java language is an ideal choice for Android developers, lan anggota O'Reilly seneng akses tanpa wates menyang konten digital lan latihan online langsung. Android-App-Programmieren ing Jawa nyakup kabeh aspek penting pangembangan aplikasi profesional. Nggunakake buku iki bakal ngidini sampeyan nggawe aplikasi profesional sing bisa disebarake liwat Google Play lan iOS.

Tujuan-C

Sampeyan bisa uga wis ngerti dhasar basa Objective-C. Objective-C minangka turunan saka Smalltalk lan nduweni sintaksis sing padha karo C. Uga ndhukung olahpesen gaya Smalltalk. Salah sawijining prabédan utama antarane C lan Objective-C yaiku kode C dikompilasi menyang perpustakaan asli, nalika kode Jawa bisa nelpon fungsi iki langsung. Akibate, Kode Objective-C luwih rumit tinimbang Jawa, nanging kurva sinau minimal.

Yen sampeyan nimbang sinau Objective-C, sampeyan bisa nemokake kursus online sing dirancang khusus kanggo platform Android. Padha asring dirating dhuwur, nanging mbutuhake ragad langganan. Rega beda-beda miturut panyedhiya lan jinis aplikasi sing dikembangake. Ora kaya PWA, yaiku aplikasi web, app native bisa diundhuh saka Google Play utawa toko app. Mupangat utama aplikasi asli yaiku nduweni fungsi luwih akeh tinimbang PWA.

Ana sawetara pro lan kontra kanggo Objective-C lan Swift. Loro-lorone basa kuat, nanging yen sampeyan ora yakin babagan basa sing digunakake, nyoba Kotlin, alternatif liyane pangguna-loropaken kanggo Jawa. Luwih gampang sinau lan nyedhiyakake pengurangan kesalahan sing luwih apik. Kotlin uga apik kanggo program Android, lan nduweni sertifikasi resmi saka Google.

Cepet

When it comes to developing apps for Android, the programming languages Swift and Kotlin have risen to prominence. Both of these open-source languages are the successors to Java and have become an integral part of the repertory of professional app developers. The following article will provide a quick overview of the two languages and what you should expect from each. After reading it, you’ll be well-equipped to start creating your first apps.

When it comes to learning the newest programming language, Swift is an excellent choice for Android. It is a robust and intuitive language that allows developers to implement their own ideas. And because it’s free, anyone with an idea can use it. Perusahaan sing adhedhasar Koblenz, United Coding GmbH & Co. KG, spesialisasi ing pangembangan app Swift. Ing ngisor iki ana sawetara mupangat sinau Swift.

Kauntungan paling gedhe saka Swift tinimbang Objective-C yaiku luwih portabel lan duwe watesan sing luwih sithik tinimbang pasangane.. Uga luwih cocog kanggo proyek tingkat perusahaan, amarga Apple ora nyetujoni nganyari OTA Android. Menapa malih, sampeyan ora bisa ngganti tujuan aplikasi Android nalika nggunakake Swift. Sampeyan uga bisa nemokake conto kode Swift ing platform Android resmi. Nanging, iku penting kanggo ngerti sing Swift ora mung basa kanggo pembangunan Android.

ShareActionProvider

Yen sampeyan pengin nuduhake app Android karo wong liya, sampeyan bisa nindakake karo ShareActionProvider. Android duwe API sing diarani ShareActionProvider, sing ngijini sampeyan nuduhake data antarane app beda. Sampeyan bisa nggunakake ShareActionProvider kanggo nggabungake iki menyang Action Bar. Iki bakal dibahas kanthi luwih rinci ing tutorial iki. Nanging saiki, kita bakal fokus ing implementasine dhasar.

Kanggo nggunakake ShareActionProvider, sampeyan kudu nggunakake Pustaka Dhukungan Android. Pustaka iki bisa digunakake ing versi Android sadurunge 4.0. Bisa digunakake karo ACTION_SEND API Android, supaya kompatibel karo versi lawas saka platform. ShareActionProvider ngidini sampeyan nampilake menu, nggawe submenu dinamis, lan nindakake tumindak standar. Bisa diumumake ing file sumber menu XML aplikasi Android sampeyan, lan bisa digunakake kanggo nuduhake isi karo aplikasi liyane.

Pustaka pemrograman aplikasi Android iki ngidini sampeyan pamisah ActionBar dadi sawetara bagean. Kanthi nggunakake ShareActionProvider, sampeyan bisa nggawe item menu sing ngidini sawetara pangguna ngakses data sing padha. Iki migunani banget kanggo nggawe aplikasi sampeyan luwih interaktif, ngidini sampeyan ngumpulake informasi, bareng karo app liyane, lan ngirim tandha lan kabar menyang app liyane. Sampeyan malah bisa nambah ShareActionProvider menyang Bar Tindakan app lan ndeleng cara kerjane.

Seret lan selehake

Yen sampeyan pengin nggawe aplikasi Android sing ngidini pangguna nyeret lan nyelehake file utawa obyek, Dhukungan seret lan selehake minangka cara sing apik kanggo miwiti. Acara seret dikirim dening sistem seret Android kanggo metode callback lan pamireng operasi seret. Acara sing diasilake ngemot data lan argumen. Para pamireng bakal ngolah acara kasebut lan nemtokake manawa data kasebut kudu ditampa utawa ditolak. Sampeyan bisa sinau luwih lengkap babagan operasi seret ing ngisor iki.

Sampeyan uga bisa sinau carane ngleksanakake nyeret ing Android kanthi ndeleng internal framework lan kelas acara seret lan pamireng.. Kelas acara seret lan pamireng seret nyedhiyakake pancingan sing dibutuhake kanggo miwiti operasi seret. Nalika pangguna nyeret tampilan, menehi data seret lan callback DragShadowBuilder. DragShadowBuilder nemtokake gambar sing digunakake sajrone operasi seret.

Sampel DragAndDrop ing GitHub kalebu conto aplikasi DragAndDrop. Sampel iki nduweni API seret lan selehake kanthi akeh fitur sing migunani. DRAG_FLAG_GLOBAL lan DRAG_FLAG_GLOBALE, bebarengan karo wadhah app target. Kode kasebut uga nduweni logika kanggo kasus DragEvent liyane. Nalika pangguna nyeret obyek, aplikasi informed iki dening ngirim kabar kanggo sistem.

Niat

Maksud migunani nalika sampeyan kudu ngalih ing antarane loro utawa luwih aplikasi. Intents bisa ngubungake aktivitas ing aplikasi sing padha utawa ing antarane aplikasi sing beda. Kanggo ngalih ing antarane rong aplikasi, sampeyan bisa nggunakake obyek anyar lan kelas maksud. Sawise sampeyan ngerti jeneng maksud sampeyan, sampeyan bisa nelpon kanthi cara putExtra. Sampeyan bisa nggunakake macem-macem jinis data, kalebu obyek lan nomer, minangka parameter kapindho sampeyan. Ing ngisor iki sawetara conto maksud.

Intents bisa migunani ing aplikasi Android kolaboratif. Sampeyan bisa nggunakake kanggo miwiti aktivitas anyar utawa kanggo nggawe sing wis ana tumindak. Maksud uga bisa digunakake kanggo miwiti layanan anyar, ngirim instruksi kanggo sing wis ana, utawa ngirim pesen menyang panrima. Pangembang Android uga bisa nggawe aplikasi kolaboratif kanthi nggunakake saringan maksud. Kanggo iki, sampeyan kudu nyiyapake piranti virtual. Sawise nggawe piranti sampeyan, nginstal versi paling anyar saka app sing nangani maksud.

Langkah sabanjure ing pemrograman aplikasi Android yaiku nggawe maksud. Intents minangka cara supaya sistem Android ngerti apa sing dikarepake app sampeyan. Cara iki ngidini sampeyan nemtokake tumindak sing pengin ditindakake ing wektu tartamtu. Tuladhane, yen sampeyan duwe aplikasi seluler kanthi rong aktivitas, maksud bisa micu aktivitas B. Yen pangguna pengin mbukak situs web tartamtu, sampeyan bisa miwiti aktivitas A kanthi aktivitas sing dipicu maksud.
