Wani sabon kwas na koyon ci gaba yana nufin koya muku abubuwan da ke cikin Swift da yadda ake rubuta aikace-aikacen duka biyun. The course will introduce you to the basic features of Swift and teach you how to write an Android App. It will also show you how to port an iOS project to Android and develop a cross-platform App.

Before you begin coding, you will need to download the Android SDK. You can download this from Google Play Developers and install it on any computer. Once you have downloaded the SDK, you can start building Android applications. You will need a Google Play Developers account. You can sign up for one for $25 USD and pay with a credit card. You can also start learning to program using a programming language like Java through a free online course like SoloLearn.

ShareActionProvider

ShareActionProvider is a class that enhances the interaction of menu components in Android apps. Zai iya haifar da menus mai ƙarfi da aiwatar da daidaitattun ayyuka. Kuna iya ayyana wannan ajin a cikin fayil ɗin albarkatun menu na XML na app ɗin ku. ShareActionProvider ne ke da alhakin ƙirƙirar ra'ayoyin da za a iya rabawa a cikin app ɗin ku.

Da zarar wannan ya cika, aikin zai koma kan Android app. Wannan mataki ne mai mahimmanci a cikin tsarin haɓaka app na Android.

Don fara haɓaka aikace-aikacen Android, kana bukatar ka san tushen tushen Android-Apps. Android shahararriyar OS ce ta wayar hannu. Yana da babban ɗakin karatu na kayan aiki don haɓakawa, ciki har da Android Studio. Kuna iya samun damar rubutu da koyaswar bidiyo da yawa don taimaka muku farawa. Hakanan, 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.

Object-Oriented Programming

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. A maimakon haka, 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 kuma ya zama yaren shirye-shirye na asali na dandamali na Android. Shahararren yare ne mai tsaftar abu wanda ke da fa'idodi da yawa. Yana da sauƙin koyo da sauƙin canja wuri daga dandalin kwamfuta zuwa wancan. Hakanan yana da ƙarfi wanda ya sa ya zama yaren zaɓi don ba da mafita ta Intanet gabaɗaya.

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.
