Hoe Android-apps bouwe mei Java, Kotlin, C++, en Snapseed

If you’ve ever wondered how to build an Android app, the answer is to start with Java or Kotlin. You’ll also need a decent knowledge of C++ or Snapseed. If you have no idea what any of these languages are, meitsje dy gjin soargen – we’ll explain the basics. Once you know the basics, you can start building apps and interacting with them on your device! Einsluten, you’re just an ordinary user, rjochts?

Java

You’ve probably heard of Android, but you may not be familiar with Java apps. Developing mobile apps for the Android platform is a common practice among many developers. Android Studio is the leading Android development tool and comes with a wide variety of powerful libraries of code, including Java tutorials. It also has an extensive documentation section, En jo kinne direkt begjinne mei de tutoriale fideo's. Mar jo moatte ek wat kennis hawwe fan Java om it proses nofliker en produktyf te meitsjen.

As jo net wis binne wêr't jo wolle begjinne as it giet om te learen Java, Jo wolle wierskynlik ien fan 'e fergese tutorials downloade. De tutorials op dizze programma's binne oer it algemien tige behelpsum en maklik te folgjen. Dyjingen dy't net folle witte oer Java soe moatte begjinne mei Enki. It lit jo de basis fan Java-ûntwikkeling leare en it yn it echte libben tapasse. Dcoder en Droidedit binne de twa bêste Java-ides foar Android. Beide kinne jo koade direkt bewurkje fan jo smartphone, wêrtroch se it perfekte ark meitsje foar begjinners.

Wylst Android net it perfekte platfoarm is foar elk type ûntwikkelder, Java remains the most popular programming language for mobile devices. Many professional developers use Java to create their apps. The Android platform’s portability and familiarity with this programming language make it an excellent choice for anyone developing mobile apps. lykwols, before you make the decision to switch over to Android, you should consider your target market. There are many advantages to using Java for Android development. If you’re planning to develop a global app, Java is the most suitable choice.

A good IDE for Android is essential for making sure your code compiles correctly. JStudio has many benefits, including auto-completion and code-completion features. Besides that, it has a built-in terminal, which lets you perform Android-related commands. Derneist, it helps you manage java files, copy and paste code, and even perform real-time error checking. This makes Java development on Android a breeze.

Kotlin

Java is the oldest programming language, and it still rules the app development world. Its high-end scripting capabilities make it an excellent choice for many developers, but it does have its drawbacks. In recent years, the development of Android apps has necessitated the use of a new coding language. Kotlin for Android apps is one such language. With a recent announcement from Google, Kotlin is now the preferred language for developing Android apps.

Although Kotlin syntax is similar to Java, there are some distinct differences between Java and Kotlin. For starters, Kotlin supports both procedural and object-oriented programming. It is statically typed, which means that data types can be defined in two different ways: nullable and non-nullable. The latter is useful for maintaining your Android app’s codebase. You can also create reusable classes and components in Kotlin by using the project wizard.

Another difference between Java and Kotlin is the extension mechanism. While Java provides an API for extending existing classes, Kotlin lets you add the class name to a function’s name. In Java, you must inherit the parent class’ functions. But in Kotlin, you can add your own function name and inherit the same class’s API. Dizze manier, you can extend your class’s functionality without modifying its structure or code.

As with any new language, learning Kotlin is not easy. There are certain issues you should be aware of before implementing it in your project. If you are not ready for the learning curve, it is best to stick to a familiar programming language such as Java. While it can be challenging for beginners, it is the perfect choice for seasoned Android developers. The language is comparatively easier to learn and streamlined the development process for custom Android apps.

While Java is easier to learn and more familiar to developers, it doesn’t offer the same features as Kotlin. Bygelyks, Java does not support coroutines, which is a programming model that allows multiple threads to be created simultaneously. Using multiple threads increases the size of the codebase and can lead to errors. Derneist, Java-ûntwikkelders moatte fariabele soarten manuell ynspektearje en har op basis fan har operators smite. Kotlin biedt in yntelliginte kompilator dy't automatysk Redundant Casts ferfangt mei stabile wearden.

C++

As jo in Android-app wolle ûntwikkelje, Jo moatte wite dat C ++ in oantal foardielen hat oer Java. Dit is om't C ++ in soad rapper is by algoritmen wêrby't in soad fariabelen belutsen binne. Ek, As jo fan plan binne de app te brûken om spultsje-motoren of CPU-yntinsive applikaasjes te meitsjen, jo moatte beskôgje mei C ++. Java hat ferskate neidielen, Dat jo moatte Java moatte leare foardat jo nei C ++ ferpleatse. Dit artikel sil de foardielen fan C ++ ferklearje foar Android Untwikkeling.

Java is in geweldige programmeartaal, Mar C ++ hat ferskate foardielen. It is mear fleksibel en besette minder ûnthâld dan Java, en it is makliker om ferskate software te fergelykje. C ++ is ek rapper dan Java, Dat jo kinne bugs makliker fine. lykwols, C ++ hat gjin standert brûkersynterface lykas Java. C ++ kin brûkt wurde foar komplekse taken, Mar it hat net safolle funksjes. C ++ is ek mear kompleks dan Java, Dat jo moatte bewust wêze fan dizze ferskillen foardat jo beslute om te brûken.

Om in nij projekt te meitsjen, iepenje it ide. Navigearje nei it projektpane oan 'e linkerkant fan' e ide. Út it útklapmenu, Selektearje de nije map as C ++-boarne-bestân. Klikje op it drop-down-menu om de bestâns-útwreiding te selektearjen. Jo kinne dan de oanpasse fan 'e oanpasse C ++-stipe-knop om mear bestannen ta te foegjen oan it projekt. As alternatyf, Jo kinne in nij projekt oanmeitsje en it selektearje as de 'lânseigen C ++’ projekttype.

In oare populêre programmeartaal foar Android-ûntwikkeling is Java. Dit is de âldste en meast brûkte programmeartaal en bliuwt noch populêr fanwegen syn wiidweidige biblioteek en dwersskompilaasjesmooglikheden. Kotlin is in populêr alternatyf foar Java. It is in lân foar cross-platfoarm en is rap genôch foar mobile apparaten. It produseart ek lytsere útfiertables. Nettsjinsteande syn kompleksiteit, Java is in geweldige kar foar Android-app-ûntwikkelders.
