如果你係Android開發嘅新手, you’ve probably heard about Java, 目標-C, or Swift. If you’re interested in becoming a mobile app developer, you might be interested in learning about Android Programming Fundamentals. The course will also introduce you to Swift. It’s geared toward Java developers, but it’s helpful for all programmers. The objective of this course is to provide you with the basic knowledge of these languages to make it easier to begin creating Android apps.
The Android programming language is a popular choice for software developers. You can find a wide variety of books and tutorials on Android programmierung in Java. 然而, if you are completely new to programming for Android, it will take a bit of effort to understand the various concepts and languages. 在本文中, 我哋會講解 Java 嘅 Android 編程基本知識，同埋你可以用嚟創建你嘅應用程式嘅各種開發環境.
安卓應用程式係由各種活動組成, 可以喺螢幕頁面睇到. 當你撳一下其中一個畫面, 你會移去下一個活動. 主要活動係由 Java 班組成, 呢啲係活動同 AppCompat 活動嘅子類. 呢個係你個應用程式嘅入口，同埋有靜態方法主要() 同埋喺創建(). 用緊呢啲班, 你將可以建立一個可以喺任何 Android 裝置上面順利運作嘅用戶介面.
當你開始用 Android, 你一定要學 Java. 你可以透過入門書或者免費嘅應用程式開發工具包，了解 Java 嘅基本介紹. Java 係一種流行嘅編程語言，用嚟創建 Android 應用程式, 但係佢有好多陷阱. Java 嘅主要問題係佢需要一種完全唔同嘅編程風格. 儘管 Java 係一個受歡迎嘅選擇, Python 作為學生嘅入門語言一直都係越嚟越有地位.
作為 Java 嘅替代品, 好多開發人員都轉用緊 Kotlin. 與爪哇不同, Kotlin 係唔關平台事，可以好快學到. 佢亦都提供更大嘅錯誤減少, 令到 Kotlin 成為 Android 程式設計嘅好選擇. 索倫 · 羅克爾喺3pc 新通訊有限公司做嘢, 同埋有 Java 嘅 Android 編程技巧同埋喺流動應用程式入面使用 Artliche 智能嘅技能.
如果你需要你嘅應用程式快速執行, Java 係比 Python 更好嘅選擇. Python 冇虛擬機器支援, but Java has extensive optimization functions. Both languages offer libraries and APIs for Android programmers to use. While both languages have a variety of advantages, Python is better for developers who need to work with a legacy system. It is also easier to step-change systems. Despite the differences, both languages have plenty of benefits for Android programmers.
The author also provides a comprehensive introduction to Android programming in Java. It explains the important aspects of professional app development, from data storage to background processes. The book shows readers how to use Android Studio effectively. The book also covers how to use the Android SDK, data storage, and Internet-Services. A great guide for aspiring Java developers, Android Programming in Java is an excellent resource. 學緊語言嘅時候, 你會對 Android 生態系統有更深入嘅認識.
如果你想為 Android 裝置開發應用程式, 你應該知道關於 Android 嘅 Objective-C. 目標 C 係源自 Smalltalk, 一種用嚟創建軟件嘅語言. 佢嘅語法同 C 好相似, 但係佢實現咗 Smalltalk 式嘅訊息. 當您使用 Objective-C 創建 Android 應用程序時, 你應該確保將實現同接口宣布為獨立嘅代碼塊. 你應該將個介面放喺個頭檔案入面，而個實現就放喺個代碼檔案入面. 呢兩個檔案都同 C 代碼檔案好相似, 所以你可能想喺開始之前睇吓兩者嘅文件.
用 Objective-C 嚟做 Android 編程有幾個好處. 同斯威夫特相比, 呢種語言好易學, 提供極端嘅性能, 而且被廣泛推薦用於建立新平台. 佢亦都快過目標 C, 但係佢冇咁成熟. 然而, 佢仍然會收到日後嘅更新，並且隨住時間嘅推移而變得更好. 無論 Swift 嘅缺點係點, 開發人員可以同 Objective-C 一齊用佢，噉樣會受益.
而 Java 語言係 Android 最流行嘅編程語言, 用 Android 版 Objective-C 時，有幾點要記住. 例如, 你可以存取更廣泛嘅庫同工具. 目標 C 亦都係比 Java 更易用, 噉你就可以為 iOS 同 Android 寫應用程式. 如果你想用 Java 去開發你嘅應用程式, 你需要理解佢嘅語法，同埋用一個可以喺 iOS 裝置上面執行佢嘅 IDE.
Kotlin 係一種用嚟開發 Android 嘅開源語言. 佢係發明喺 2011 同埋喺主要穩定交付中釋放咗 2016. 喺 2017, Google 宣布 Kotlin 係佢最好嘅應用程式開發語言. 但係呢個決定並唔係最後嘅, 因為 Google 喺 Java API 上面同甲骨文進行緊法律戰. 雖然佢有好多優點, 佢仲係劣於 Android 程式設計嘅 Objective-C. 佢嘅功能少啲，同埋比 Java 慢.
作為 Apple iOS 裝置嘅預設語言, Objective-C 有一個好大嘅庫，幾乎每個 iOS 開發人員都熟悉. 目標 C 係一種可靠嘅語言, 而且你唔使不斷更新佢, 唔似市面上其他好多編程語言. 然而, 語言唔係好靈活, 而你喺揀啱你嘅流動開發嘅語言嗰陣應該緊記呢一點. 然而, 如果你個諗法夠複雜, 你應該為個項目揀另一種語言.
亦都好易學, 而且開始唔難. 你唔使知道任何代碼就可以開始, 因為你會喺 Android 嘅 Objective-C 入面搵到有關 Android 開發嘅教學. 你甚至可以喺官方 Google Play 商店下載 Android 版 Objective-C. 噉樣會幫你學習語言，令你嘅應用程式更加有效率. 你可以即刻開始寫你自己嘅應用程式!
如果你係一個開發緊 Android 應用程式嘅開發人員, 你可能會諗你應唔應該學點樣用 Swift 定係 Kotlin 編程. 呢兩種編程語言都係開源嘅，而且越嚟越受歡迎, 但你應該學邊個先? 喺呢篇文章入面了解更多有關兩者嘅資訊. If you’re already familiar with Java, you can also move on to Swift. But if you’re looking for something new, consider learning Kotlin first.
The language is a great choice for building mobile apps. It’s free and open source and works on both Mac and iOS devices. It also allows you to contribute to the Swift Quellcode and download binaries for Linux and OS X. If you’re interested in learning how to code in Swift, it’s important to remember that the programming languages are quite similar. Swift is more complex than Objective-C, but it’s not impossible to learn.
Both Swift and Kotlin are statically typified programming languages, and they are widely used in iOS and Android apps. Kotlin has been replacing Java as the most popular language for Android app development. It is fully compatible with Java and is constantly being developed. But the differences between Kotlin and Swift are not great, and you should only use them if you’re already familiar with Java. You can also choose to learn Kotlin if you’re looking for an alternative to Swift or Java.
While you should learn Swift to code for Android, it would be best if you already know Java. The native programming environment of Android uses LLVM compilers, so your Swift code will be interpreted just like any other C/C++ code. 除此之外, you’ll also be able to reuse C/C++ development tools, such as the low-level debugger and profiling tools. 你會想知道呢啲語言係咩，因為佢哋都係為咗同一個目的而寫嘅: 開發 Android 應用程式!
Android 開發人員可以揀任何適合佢哋需要嘅編程語言. Swift 係 iOS 最流行嘅編程語言, 但係佢亦都係一種極其強大嘅 Android 編程語言. 編程語言嘅分別, 同埋佢哋跑嘅平台, 都好重要. iOS 應用程式開發對兩個平台嚟講都係更有效率, 但係 Swift 一般對程式設計師嚟講比較容易學習. 兩種語言嘅優點都值得學習曲線. 呢篇文章會講解兩種語言嘅分別, 同埋畀你一個好嘅概念，知道邊種語言更適合你嘅特定需要.
iOS 應用程式好靈活, and can be tailored to meet your needs. Swift is an excellent choice for this kind of development. The authors walk you through the entire process step by step, providing practical examples and avoiding pitfalls along the way. You can also take advantage of iOS’s licensor terms and guidelines, and learn about the requirements of Apple’s strict app approval process. If you choose this path, you’ll be well on your way to making a successful app.
