Sinau Dasar Programmierung Android ing Jawa lan Lingkungan Pangembangan Beda

Yen sampeyan kasengsem ing programming Android, Sampeyan duwe akeh pilihan sing kasedhiya kanggo sampeyan. Sampeyan bisa miwiti kanthi ndeleng toko Google Play, sing wis rampung 3 yuta aplikasi. Akeh sing migunani lan wis diprogram kanthi apik, Dadi sampeyan kudu nimbang nggunakake salah sawijine. Kajaba Jawa, Sampeyan uga bisa nggunakake objektif-C, Cepet, lan sign XML Chain.

Jawa

Android Programmierung ing Jawa minangka basa sing digunakake kanggo ngembangake aplikasi Android. Basa kasedhiya ing macem-macem tutorial lan buku lan mbutuhake karya lan komitmen sing sethithik kanggo dikuasai. Tutorial iki bakal mbantu sampeyan sinau dhasar programmierung ing Jawa lan lingkungan pangembangan sing beda.

Salah sawijining keuntungan saka aplikasi Android adhedhasar Java yaiku bisa mbukak macem-macem platform. Loro Jawa lan Python nyedhiyakake macem-macem perpustakaan lan API kanggo programer Android. Yen sampeyan rencana nggarap sistem warisan lan kudu ngembangake aplikasi kanthi cepet, Jawa dadi pilihan sing luwih apik.

Java ndhukung coroutines, sing ngidini sampeyan nggawe macem-macem benang eksekusi. Nanging, Iki bisa nambah ukuran codebase program lan nambah risiko kesalahan kode. Kerugian liyane Jawa yaiku mbutuhake sampeyan mriksa jinis variabel kanthi manual. Kanggo ngindhari iki, Sampeyan kudu nggunakake basa pemrograman sing ndhukung casts pinter. Fitur iki ngganti calon sing luwih murah kanthi nilai stabil.

Kejabi nyedhiyakake introduksi lengkap menyang program Android ing Jawa, Buku kasebut uga nyakup topik penting kanggo pangembangan aplikasi profesional. Iki kalebu ngerteni data data lan latar mburi. Kajaba iku, Sampeyan bakal ngerti carane nggunakake Studio Android lan Android SDK.

Tujuan-C

Yen sampeyan nggoleki kanthi cepet, Cara Gampang Ngembangake Aplikasi Android, Sampeyan kudu nimbang nggunakake objektif-C. Basa iki padha karo Jawa lan duwe alat lan perpustakaan sing apik kanggo digunakake. Iki uga luwih ramah pangguna lan bisa digunakake kanggo nggawe aplikasi kanggo iOS lan Android. Sampeyan kudu duwe kawruh sing apik kanggo Jawa, Dadi penting kanggo milih ide sing bisa mbukak ing Android lan IOS.

Objektif-c minangka basa pemrograman sing cocog kanggo wong sing duwe pengalaman karo C ++ nanging ora pengin mlebu ing jaman Jawa. Nanging, Luwih alon tinimbang Jawa lan duwe sistem dhukungan sing winates. Yen luwih seneng nggunakake objektif-C, Sampeyan bisa njaluk tangan ing kit PspDF.

Objektif-c minangka superset c lan ngemot akeh fitur sing berorientasi obyek. Iki uga minangka program pemrograman sing relatif stabil, Kanthi komunitas gedhe lan perpustakaan lan dokumentasi gedhe. Sing paling apik babagan sampeyan bisa sinau kanthi cepet lan bisa nggawe app sing apik banget.

Objektif-c ndhukung loro statis lan dinamis ngetik loro. Iki tegese kode sampeyan bisa dicenthang kanthi nyata kanggo kesalahan. Nanging, Basa iki duwe sejarah sing dawa. Minangka basa open-source, Sampeyan bisa nemokake macem-macem alat saka perusahaan apel lan katelu. Apple bubar ngenalake alat anyar kaya Pencostkit (Kanggo potlot apel) lan sirikit (Kanggo aplikasi pihak katelu). Uga ndhukung Mirkit, sing nambah kemungkinan kanggo imbuhan UI.

Cepet

Yen sampeyan pangembang Android lan pengin nggawe app sampeyan mbukak platform sing beda, Swift minangka alat sing pas kanggo proyek. Nduwe akeh fitur sing cocog kanggo pangembangan mobile, Lan gratis kanggo pangembang. Uga ndhukung macem-macem target pangembangan, kalebu ndk Android, Koko, Jawa, lan liyane.

Yen sampeyan arep nggunakake cepet kanggo pangembangan Android, Minangka apike duwe pengalaman ing basa program liyane, Utamane Swift kanggo iOS. Basa punika open-source, tegese sampeyan bisa nemokake akeh wong sing gelem nulungi. Sampeyan uga bakal bisa nggunakake cepet kanggo ngembang aplikasi iOS, lan pangembang iOS bisa uga dijaluk nulis aplikasi Android kanthi cepet. Saliyane fleksibelane, Swift uga cepet lan gampang sinau.

Nalika Swift minangka basa sing mbukak, you’ll be able to use your favorite tools with it, including the Android NDK. This means you’ll be able to use most of the tools you’ve used for C/C++ development, such as the low-level debugger.

Swift is also very interactive, which means you can write code in a terminal or the LLDB debugging console of Xcode. This means you can interact and evaluate your running apps, write new code, and run tests easily.

string XML

XML is a markup language used to define data. It is derived from the Standard Generalized Markup Language (SGML). XML iku entheng, scalable, and easy to write. It is used to implement data for the UI of Android applications.

Framework Asynctask

The AsyncTask-framework for Android programming provides a convenient way to communicate between the main thread and background thread. Kerjane kanthi ngliwati asil saka latar mburi metode latar mburi kanggo cara OnpostExEcute, sing banjur nampa asil saka metode latar mburi. Iki minangka pamblokiran bangunan program pemrograman Android.

Asyntask minangka kelas abstrak sing menehi kerangka dhasar kanggo tugas sing ora seger. Ana telung metode utama ing Asyntask. Pisanan, onpreexecute, mlaku ing benang utama, nyiapake dialog loading lan peringatan pangguna sing kudu diwiwiti. Cara kapindho, Dointbackground, mlaku ing benang sing kapisah ing latar mburi.

Saliyane bisa nglakokake tugas ing latar mburi, Asyntask uga ngidini aplikasi nerbitake nganyari UI nalika ngolah tugas latar mburi. Amarga Android Kegiatan mlaku ing benang utama, Nganggo tugas-tugasku / o utawa prosesor-intensif tugas ing benang iki bisa waras ui. Asyntask nyedhiyakake kerangka pangembang aplikasi Android kanggo ngetrapake tugas sing bakal ditindakake ing benang latar mburi benang utama ngrampungake pakaryane.

AsyncTask-TOG-TOG-Framework minangka sistem sing disebarake sing ndhukung puluhan ewu tugas ASLI per detik. Pengembang kasebut nggawe kerangka sawise ora nemokake solusi sing ora ana kanggo kabutuhan tartamtu. Engineer Dropbox nggunakake ATF ing 28 tim teknik lan saiki ngiseni akeh 9,000 Tugas Async per detik.

Aplikasi Android asli

Aplikasi Android asli dirancang kanggo mbukak piranti Android. Dheweke bisa digawe nggunakake HTML, CSS, utawa javascript. Basa iki kompatibel karo piranti Windows lan piranti Android. SDK Android uga ndhukung teknologi salib platform, kalebu xamarin. Android. These tools let you build native Android apps using a common language infrastructure and share code across platforms.

Developed using the native framework of the mobile operating system, native apps use the native functionality of the mobile device. This makes them fast and take advantage of the platform’s features. Native apps can even incorporate operating system gestures. They can also be secure and use the security features of their respective operating systems.

Native Android Apps have an advantage over hybrid apps. Native apps use native language capabilities and can use more native features. Kajaba iku, they can use the Internet of Things (IoT) devices, virtual reality (VR), and augmented reality (AR). They also follow the platform’s design guidelines, providing a more immersive experience for users.

Another advantage of native apps is the ability to control their size, orientation, and resolution. Since native apps are optimized for the OS, they can be targeted to the right device, which makes them faster. Tuladhane, the Facebook application was once written in HTML5 code and was significantly slower on iPhones. In response to this, Facebook app developers decided to develop separate code for the iOS platform. This gave Facebook the ability to optimize the code to run faster on iOS devices.
