Faa'iidooyinka Java ee Horumarinta Android

Android is one of the most popular mobile operating systems today. It has a market share of 75 percent and is used by more than 2 billion people worldwide. If you’re interested in learning more about the system, there are a lot of resources available. One of these resources is the Android SDK. You can also learn more about Kotlin and Java.

Entwickler sind bestens vertraut mit: Android SDK

When you develop an application for the Android platform, you must get to know its platform architecture. This refers to the number of processes that take place when you start your application, as well as the communication between applications. Intaa waxaa dheer, you need to get familiar with the different components of Android, including Activity, Fragment, Service, and Intent. Intaa waxaa dheer, Waxaad u baahan tahay inaad ogaato isbeddelada ugu dambeeyay oo aad raacdo isbeddelada ugu dambeeyay ee ku saabsan horumarinta barnaamijyada Android.

SDK-ga Android SDK waxaa ku jira aalado horumarineed oo kala duwan iyo maktabado kuu oggolaanaya inaad dhisto oo aad bilowdo barnaamijyo. Waa inaad haysataa aqoon shaqo oo ku saabsan aaladahaan oo aad cusboonaysiiso markii Google ay soo saarto noocyo cusub. Sidan, Waxaad ka heli kartaa inta ugu badan astaamaha ugu dambeeya oo aad horumarin karto waxqabadka app-ka.

Kotlin

Haddii aad raadineyso luqad cusub oo ku saabsan horumarkaaga Android App, Waxaa laga yaabaa inaad rabto inaad hubiso kotlin. Waa luqad java-jecel oo leh faa iidooyin badan, waxaana loo isticmaali karaa dhowr hawlood oo kala duwan. Waxay kaloo leedahay faa iidada in lagu beddelo java-bytecode, taas oo ah muuqaal weyn oo loogu talagalay bilowga ah.

In kasta oo Kotlin caan noqdo, you’ll have a hard time finding resources on learning it if you’re new to it. Nasiib wanaag, there are some online resources that will give you the basic information that you need to get started. Kotlin has a small developer community, which can provide answers to questions about the language. Kotlin is also a lot faster than Java, which means that it can be used more efficiently.

Java, marka la barbardhigo, requires controlled exceptions, which can make the code very long. Those are just a couple of the things you need to be aware of before diving into the world of Java.

Java

When you develop an Android application, you have to make sure to choose the right language. If you are new to programming for Android, you should start with Java. You can use Java to create both native and hybrid apps. There are plenty of examples and resources available to get you started. The following are some benefits of Java for Android development.

Java supports Java Native Interface (JNI) which defines the way Java and Android bytecode interact with each other. It is also possible to write Android managed code in Java or Kotlin. Kotlin is a language that compiles to bytecode in the same way as Java.

When developing an Android application, you should follow the Android developer’s guide. It provides an overview of the main features of the Java programming language and provides examples of how to work with them. This guide also covers performance issues and the various tools available to optimize your apps.

Toorreey

The Dagger Android development platform is a new framework for Android application development. Waxay bixisaa qaab-dhismeedka irbadaha saafiga ah, kaas oo ka caawiya soosaarayaasha inay ku qoraan koodh android ah oo leh khaladaad yar oo ay wanaajiyeen xasilloonida muddada-dheer. Qaabdhismeedka waxaa loogu talagalay qaab dhismeedka software-ka, Moodhkeeda barashada is dhexgalka ayaa kuu oggolaaneysa inaad aragto oo aad la kulanto hirgelinta.

Sida horumariye Android ah, Waxaad u baahan tahay qaab dhismeedka xamili kara kakanaanta suuqa mobilada. Tusaale ahaan, Taleefanno badan oo gacanta iyo kiniiniyada ayaa adeegsada softiweer ku saleysan Android-ku-saleysan, taas oo micnaheedu yahay inaad u baahan tahay inaad yeelato qaab-dhismeedka wax ka qaban kara noocyada nidaamka kala duwan iyo cabbirka shaashadda. Dagger waa doorashada saxda ah ee tan, Sida ay u siiso hubinta buuxa, wuxuuna ku habboon yahay horumarka Android.

Dogger wuxuu isticmaalaa proguard bytecode rettor to to pass-ka code-ka Java. Tani waxay awood u siineysaa inay soo saarto ilo dabiici ah. It also ensures that Java source is compatible with ProGuard optimizations.

Goobta-Adeegyada API-yada

Haddii aad tahay horumariye Android, you’re probably interested in using Location-Based Service APIs to track the location of your app users. The Location-Based Service APIs allow you to create location-aware apps with ease. You can use these APIs to add features such as geofencing and activity recognition to your applications. The APIs return a range of information including the approximate distance, speed, and accuracy of the location.

The Location-Based Service APIs for Android are available from infrastructure manufacturers and help developers build mobile apps more efficiently. Whether you’re building an app for Android or iOS, this new technology is making it easier to create a high-quality product faster. These APIs are often called “Beacon-Frames” waxayna ka shaqeeyaan Android 6.0 iyo ka dib, Daaqadaha 10, Linux 3.18, iyo aos. Waxaa lagu habeyn karaa inay ka jawaabaan cinwaanka Mac-gaar ah oo gaar ah.

In kasta oo adeegyada ku saleysan goobta ay u muuqan karaan kuwo ku habboon oo caawin kara, Waxay kaloo horseedi karaan walaac sir ah. Nasiib wanaag, Waxaa jira habab looga baxo raadinta. Tusaale ahaan, CISCO waxay bixisaa ka-bixitaan loogu talagalay dadka isticmaala oo aan rabin in la raaco.

FurGL

Markaad horumarinayso barnaamijyada Android, Waxaad u isticmaali kartaa opengl api si aad u abuurto sawirada 3aad. Teknolojiyaddan waxaa lagu taageeraa Android ee Opengl Es Api, taas oo ah dhadhanka qeexitaanka opengl ee loogu talagalay in lagu dhejiyo aaladda. API-dani waxay la mid tahay kuwa j2me opengl es api, In kasta oo aysan isku mid ahayn. Haddii aad qorsheynaysid inaad u isticmaasho opengl es app-kaaga android, Waa kuwan waxyaabo dhawr ah oo ay tahay inaad ka ogaato tikniyoolajiyadda.

Marka lagu daro bixinta sawirada 3aad, Android also provides support for 2D graphics using OpenGL ES. This variant of OpenGL is designed specifically for embedded systems and is supported in Android 1.0 iyo 2.2. Since OpenGL ES 2.0 is supported by most Android devices, you should use this version of the API in your applications.

ReactiveX/RxAndroid

The ReactiveX/RxAndroid development framework is designed to make it easier for developers to build applications with high performance. The library also provides tools to manage and handle asynchronous data streams. While the language is quite complex, it is easy to learn and remember. Intaa waxaa dheer, the library is compatible with many platforms, including Java and Android.

ReactiveX/RxAndroid development can be done in a unified development environment such as Android Studio, which has integrated test tools and debugger. Si kastaba ha ahaatee, many Android applications can be highly complex, involving many user interactions and network connections. Natiijo ahaan, the code can get quite long and may be faulty. ReactiveX is an alternative way to solve this problem. With this framework, developers can build asynchronous tasks while implementing a consistent design pattern.

ReactiveX simplifies stateful programs by using operators that reduce complex challenges to small lines of code. Traditional try/catch is ineffective for asynchronous computations, but ReactiveX also provides mechanisms for error handling. Intaa waxaa dheer, Observables and Schedulers abstract away the complexities of concurrency, synchronization, and low-level threading.

Location-Based Service Architecture

Location-based services are becoming increasingly popular for mobile applications, as they offer many benefits and useful use cases. Si kastaba ha ahaatee, Waxa kale oo jira khataro la xidhiidha adeegsiga adeegyada ku saleysan goobta. Tusaale ahaan, Qaar ka mid ah isticmaaleyaasha ayaa laga yaabaa inay ku qanacsanaadaan codsiyada la socoshada iyaga oo aan oggolaansho la'aan. Si wax looga qabto khatarahaas, Soo-saareyaashu waa inay fuliyaan hanaan ku saleysan rukhsad ee dhismaha adeegga ku saleysan goobta.

Adeeg ku saleysan goobta waa nooc ka mid ah arjiga mobilada ee adeegsada xogta Geo-Meesha si loo bixiyo adeegyo shaqsiyadeed. Codsigu wuxuu u adeegsan karaa xogtan si uu u muujiyo macluumaadka la xiriira ama hel adeegyada u dhaw, sida darawalada Cab. Si aad u awood u yeelato inaad ka faa'iideysato adeegyada ku saleysan goobta, Soosaaraha Android waa inuu fahmaa sida ay u shaqeeyaan oo ay u hirgeliyaan barnaamijyadooda.

Si loo hirgaliyo adeegyada ku saleysan goobta, Soo saareyaashu waxay u baahan yihiin inay tixgeliyaan tikniyoolajiyad kaladuwan. In kasta oo GP-yada ay xallin aad u fiican u tahay xargaha badan ee bannaanka, saxnimadeeda ayaa xadidan. Inside buildings, tusaale ahaan, it cannot pinpoint a user’s position. Other technologies exist that offer some level of location accuracy, but still have many limitations.

Android Security Architecture

Android uses a secure architecture to protect its users and its ecosystem. It starts with the kernel, and extends to native code and operating system applications. The software that runs above the kernel is called the Application Sandbox. All applications that run within the Application Sandbox are protected by a set of rules. Some platforms restrict developers to certain frameworks, APIs, and languages, but Android does not enforce any restrictions. Waxaa intaa dheer, native code is as secure as interpreted code.

Android’s security architecture protects the device from applications that perform harmful operations. Among other things, Codsiyada waxaa laga xadiday akhrinta xogta ka timaadda isticmaaleyaasha ama ku qoro faylasha aaladda. Iyaguna ma geli karaan shabakadda iyada oo aan la helin ogolaanshaha isticmaaleha.
