Me pehea te Whakataka i nga tono Android me Java

Mena kua whakaaro koe me pehea te whakawhanake i tetahi taupānga Android, e kore ko koe anake. He maha nga rauemi kei runga ipurangi, me te kaupapa Android taupānga he mea ke. I roto i tenei tuhinga, ka ako koe mo nga kaupapa whanaketanga taupānga Android, te ShareActionProvider, Nga Waea Whakahoki Ora, me etahi atu. Ka ako ano koe mo te rereketanga i waenga i nga Native Apps me Progressive Web Apps.

Java

Mena kua whakaaro koe me pehea te whakarite i nga taupānga Android, he tino ngawari te whakautu – me ako koe i te Java! E rua nga waahanga o nga taupānga Android: he Mahi me tetahi Tirohanga. Ko te ngohe e tautuhi ana i te kowhatu o runga kauwhata me te mahi o te taupānga, i te mea kei roto i te tirohanga he waehere Java e whakatau ana he aha te mea ka pehia te paatene. Ka rere nga waahanga e rua i runga i nga taputapu hototahi-Android. This tutorial will help you learn how to program Android apps with Java!

This book teaches you the basics of Java for Android development, which is essential if you want to create a professional app. It starts with the Android-Richtlinies for User Interface Design, and ends with an app featuring a timer. You’ll use Java to create the app, and you’ll gain a lot of experience in the process! It’s also packed with helpful tips to make your app a success, hoki.

The process of learning how to program Android apps begins with registering as a developer with Google. You’ll pay a one-time fee for this service, but after that, you can offer your apps for download or sale, and Google takes a provision for each sale. Android programming requires the use of the Android SDK, a ko Java he taputapu pai mo tenei. Ka taea e koe te ako Java ma te whai i enei mahi.

ShareActionProvider

Ka whakaratohia e te ShareActionProvider mo nga kaupapa Android he huarahi mo nga kaihanga ki te whakaatu i nga raraunga kararehe i roto i a raatau tono.. Ma te API ka taea e nga kaihanga te taapiri i nga akomanga ShareActionActivity me ShareActionProvider ki o raatau kaupapa Android. Ka whakaratohia hoki e te API te kaha ki te tuku raraunga ki etahi atu tono. Hei whakamahi i te ShareActionProvider mo nga taupānga Android, tuatahi hanga he kaupapa Android ka hono atu ki to PC ma te ADB. Ka hangaia he kaupapa hou ka taea e koe te whakauru ki runga i te taputapu hono. Ina oti to kaupapa hou i hangaia, ka taea e koe te timata ki te whakawaehere.

Ka taea e koe te whakamahi i te ShareActionProvider mo nga taupānga Android hei whakaatu i te tohu tiri i roto i te ActionBar o to taupānga. Ka waihangahia e te ShareActionProvider he tirohanga mo te kaiwhakamahi ki te kite i te wa e tiritiri raraunga ana. Ka whakaatu hoki i tetahi tahua iti e whakarārangi ana i nga momo mahi tiritahi. Ka taea te whakarite i te koronga mo enei mahi. Ka taea hoki e koe te taapiri i tetahi mahi ki te Pae Mahi ki te hiahia koe kia kite te kaiwhakamahi i tetahi karere e whakaatu ana i te raru.

ShareActionProvider ka taea e nga kaiwhakawhanake te tuku kawenga mo te ahua me te whanonga. Ka taea e nga kaiwhakawhanake te hanga i nga taupānga haumi e tuku ana i nga kaiwhakamahi ki te tiri i o raatau ihirangi ki etahi atu taupānga. Ka taea e ShareActionProvider nga kaiwhakawhanake ki te whakauru hononga ki te paetukutuku a ShareActionProvider i roto i o raatau taupānga. Papatono taupānga me ShareActionProvider mo Android

Nga Waea Whakahoki Ora

Hei whakatinana i nga Waea Whakahoki Ora i roto i to taupānga Android, me mohio koe ki te whakamahi i te API phi. Ka taea e te punaha te waea atu ki nga tikanga onStart me te onStop neke atu i te kotahi i roto i te roanga o te mahi. I tenei wa, ka huri te mahi mai i te kitea ki te huna, tauutuutu i waenga i te onCreate me te onStop. Ki te kite i te wa ka pakaru tetahi mahi, tirohia nga karere logcat. Mena kaore e kitea e koe te tikanga e rapu ana koe, me whakaaro koe ki te whakawhānui i te API.

I roto i te Android, ka tono koe i runga i te tiimata() ki te whakauru i tetahi mahi ki te ahua hohe. Mena kei muri te mahi, i runga Tatari() ka kiia. Waihoki, onStop() ka karangahia ina katia te mahi. Ka whakamahia nga hokiwaea e rua ki te whakawhiwhi rauemi me te whakaoti i etahi atu mahi kaha-waahi. Kua whakatinanahia ano e Android nga taurangi ko te onStop() ka kiia ko te tikanga.

Ko te huringa ora phi ka kitea ki nga tono na roto i nga mahi a te mema karanga. These callbacks follow a kind of “stack” and appear to happen in a nonhierarchical order. They also note the items that must be handled in each stage. In order to properly use Activity Lifecycle Callbacks, you should be using NativeActivity or native_app_glue. There are many examples of the two.

Taupānga Maori vs Taupānga Tukutuku Progressive

One of the main differences between Progressive Web Apps (PWA) and Native Applications is their platform of execution. While native apps are created to run directly on the device OS, PWAs are built using web technologies. They run in browsers and are therefore able to be launched quickly and inexpensively. Unlike native applications, heoi ano, they don’t require app store validation. They can be developed and launched much faster than native apps, but the developer needs to build both versions separately.

In addition to these differences, the development process is more time-consuming for native apps. Native apps often take longer to develop than PWAs, but they are generally more responsive. Because they must pass review processes, Native apps are more difficult to release and must be reviewed. Native apps also have lower battery consumption than PWAs. I tua atu, they’re easier to maintain than PWAs. Native apps also have two-step download functionality, making it much easier for developers to change content without having to resubmit the project.

I te nuinga, native apps are the preferred option for developers because they can access more features of the device. Ko enei taupānga ka hangaia ma te whakamahi i te reo hotaka motuhake me te arotau ki te whakahaere i runga i te taputapu. He pai ake te pono me te haumaru o nga taupānga Maori i o raatau PWA. Ko te mutunga, he haumaru ake ratou i o raatau hoa, a he pai ake ta ratou mahi. Na ko tehea te mea pai ake? Pānuihia kia mohio koe!

Ko te whakawhanake i tetahi taupānga Android e hiahia ana ki te whakawhanaketanga

I mua i to tiimata ki te tarai i tetahi tono Android, he mea nui ki te mohio ki nga momo waahanga o te papaaho Android me nga momo reo hotaka e whakamahia ana. Ko te Android he papaa tino wehewehenga me nga momo momo taputapu me nga punaha whakahaere. He huinga mana motuhake kei ia taputapu, and each application must declare these permissions in the application code through the uses-permission element and the Android:permission attribute.

Hei timata, an Android app declares the hardware and software features that it will use, as well as the API libraries it will use. A typical Android application includes an icon, a name for the fully qualified class name of its subclass, and a label that will be visible to the user. These components are called resources in the code of an Android app. By using these resources, the app can be optimized for different device configurations.

Learning to program an Android app is not a child’s play

The number of active Android devices is staggering. Ina hoki, there are 2.6 billion devices worldwide, making the task of creating an app seem like a no-brainer. Kotlin, a modern programming language for Android, is recommended for its syntax and code safety features. You can learn Kotlin online for free or enroll in a classroom program for an instructor-led course.

A good first-timer can start off by learning the basics using a tutorial. Hei tauira, Code Hour – Android Apps by Google is a good place to start. It teaches basic principles, but it doesn’t focus on any one programming language. Regardless of the language you choose, you’ll learn about data structures, variables, and loops. This helps you build more complex apps quickly.
