Ndikofunikira kudziwa kusiyana pakati pa zilankhulo ziwiri izi kuti mudziwe zomwe mungayembekezere kuchokera pazotsatira.

Objective-C is an object-oriented programming language similar to C and has a dynamic runtime environment. It was the predominant language used for iOS app development before Swift was introduced.

Swift

When you start coding for mobile devices, the first step is to learn the proper programming language. You may use Java, C#, HTML, CSS, or even JavaScript, but the complexity of your project will determine which language you should learn. Depending on the platform and how you intend to use your app, you may also need to use different frameworks and libraries.

Swift is a new programming language, introduced a few years ago, and is used to create iOS and Android apps. A new development learning course aims to teach you the ins and outs of Swift and how to write apps for both. Maphunzirowa akudziwitsani kuzomwe zimawalimbikitsa ndikukuphunzitsani momwe mungalembere pulogalamu ya Android. Ikuwonetsaninso momwe mungapangire polojekiti ya iOS kupita ku Android ndikupanga pulogalamu yopumira.

Musanayambe kuyika, Muyenera kutsitsa a Android SDK. Mutha kutsitsa izi kuchokera ku Google Play Opanga ndikuyika pa kompyuta iliyonse. Mukangotsitsa SDK, mutha kuyamba kumanga mapulogalamu a android. Mufunika akaunti ya Google. Mutha kusaina imodzi ya $25 USD ndi kulipira ndi kirediti kadi. Mutha kuyambanso kuphunzira ku pulogalamu pogwiritsa ntchito chilankhulo ngati java kudzera pa intaneti yaulere ngati sololearn.

ShareActionProvider

Zogawana ndi gulu lomwe limalimbikitsa kuyanjana kwamenti mu mapulogalamu a Android. It can generate dynamic submenus and execute standard actions. You can declare this class in your app’s XML menu resource file. ShareActionProvider is responsible for creating the shareable views in your app.

After installing ShareActionProvider, your application should be able to share content with other Android apps. This is done by sending an ACTION_SEND-Intent. Once this is complete, the action will return to your Android app. This is a crucial step in the Android app development process.

To begin Android app development, you need to know the basics of Android-Apps. Android is a popular mobile OS. It has an extensive library of tools for development, including Android Studio. You can access several text and video tutorials to help you get started. Komanso, you can join the CHIP forum to exchange ideas with other developers and ask questions.

Once you have an idea of the basics of Android app development, you can move on to the ShareActionProvider. This library enables you to send notifications to your users with just a few lines of code.

Kukonzekera kwa Object-Oriented

Object-Oriented programming is a key component of building Android apps. This technique uses classes to store data and perform operations on them. This is different than the imperative approach, which uses a list of commands. M'malo mwake, objects can be stored in a database and can be used to represent data in various ways.

Java is the most popular object-oriented programming language used to develop Android apps. The language was created by Sun Microsystems in 1995 ndipo wakhala chilankhulo chosasinthika cha nsanja ya Android. Ndi chilankhulo chotchuka chodziwika bwino chomwe chili ndi zabwino zambiri. Ndikosavuta kuphunzira komanso kusandukira kusinthitsa kuchokera pagawo limodzi la kompyuta kupita ku lina. Zimakhudzanso zomwe zimapangitsa kuti zikhale chilankhulo chopereka mayankho apadziko lonse lapansi.

Cholinga chachikulu cha mapulogalamu otsogola ndi kupanga mapulogalamu. Izi zimapangitsa kugwiritsa ntchito ma module angapo pazolinga zosiyanasiyana. Gawo limodzi limatha kukhala ndi tsatanetsatane wa zinthuyo pomwe wina akhoza kukhala ndi mawonekedwe oyera. Ubwino wina wogwiritsa ntchito njirayi ndikuti zinthu zatsopano zitha kupangidwa ndi kusintha pang'ono kwa zinthu zomwe zilipo. Njirayi imadziwika kuti polymorphism. Njirayi imagwiritsidwa ntchito popezeka pa intaneti ndi GUI.

Zochita za Lifecycle Callbacks

Activity Lifecycle Callbacks in Android apps allow you to manage the transition of information in your app from one state to another. Nthawi zambiri, an activity will enter the “started” state and then transition to the “resumed” or “paused” state before being destroyed. Komabe, your app can also call the onStop() method to terminate an activity before it has ended.

Activity lifecycle callbacks can also be used to handle other system events. These events can happen if a device changes its configuration. Mwachitsanzo, the device may rotate, which forces the layout of an app to change. When this happens, the system recreates the Activity and loads alternate resources.

Activity Lifecycle callback methods let you override methods and handle state changes. This is helpful if your app tries to perform long-running tasks, such as executing code. Komabe, these methods block the UI thread while executing code. Zotsatira zake, you should use these methods sparingly.

Object-Oriented Programming in Android Studio

Object-Oriented programming is a great way to organize your code. It makes it easier to find and understand what you’re trying to do. It also separates code into small pieces, which prevents code from becoming monolithic. It also helps you debug your code easier.

The basic concept of OOP is that everything has an object, a logical component that has state and behavior. These objects have methods and data attached to them. These objects are also referred to as classes. The class template defines the attributes of an object. An object can have multiple attributes, such as an address, and these attributes can be inherited from other objects.

Kumvetsetsa mtundu wa Java kumapangitsa kuti usathe kulemba nambala yabwino. Muphunzira njira yoyenera yolemba nambala yolumikizidwa ya Java, ndipo muphunzira momwe mungapangire makalasi, zigawo, ndi mawonekedwe. Muyeneranso kuphunzira za phukusi, zomwe ndizothandiza pakupanga ntchito zobwezeretsera.

Zida zosintha mu studio ya Android

Studio ya Android imapereka zida zochulukirapo kuti zisinthe. Zida izi zimakulolani kusintha nambala yanu yopanda kusintha kwa pulogalamu yanu. Mwachitsanzo, Mutha kusinthanso njira posankha chida cholingana kenako ndikugwiritsa ntchito menyu yoyenera kuti musankhe kuti musinthe. Muthanso kugwiritsa ntchito kusintha + F6 mwachidule kuti mugwire ntchito inayake.

Using refactoring tools in Android Studio allows you to write better code. You can utilize features like advanced code completion, refactoring, and code analysis. As you type, these tools provide suggestions and allow you to insert code in the appropriate place. You can also use the Tab key to insert code. You can also use the emulator in Android Studio to test your apps. It installs applications faster than the actual device and simulates a wide range of hardware features.

A great way to reuse code is to abstract it. This is an extremely helpful technique when you are working on a large chunk of code. It will prevent redundancy and duplication. Nthawi zambiri, this involves building a layer of abstraction using code, such as classes, hierarchies, ndi mawonekedwe. One of the most popular methods for removing duplicate code is the Pull-Up/Push-Down method, which pushes down the code specific to a subclass.
