Mar a nì thu prògramadh air Android App |

When it comes to making Android apps, learning the right programming language is essential. The standardized methods for developing these apps are rigid and limit the programmers’ freedom. These methods are used to create simple apps, but if you want to modify them, you must learn Java code and technical know-how.

Java

Programming an Android app is not an easy task, and requires a deep understanding of Java. Thankfully, there are apps-building kits that can help with the development process. Mura h-eil thu eòlach air Java, a beginner’s guide to the language can help you get started.

This guide covers the essential topics you’ll need to create professional apps on Android. Whether you’re just starting out or want a more thorough introduction to the language, Cuidichidh android-App-ALTERMITER ann an JAVA gus do chiad aplacaid proifeasanta proifeasanta a chuir air bhog agus a chuir air bhog. Co-dhiù a tha thu ag obair le aon aplacaid no tagradh gluasadach a tha ag amas air grunn luchd-cleachdaidh, Is e appming android-appe ann an Java an cùrsa ceart dhut. Bidh an leabhar seo cuideachd a 'tabhann trèanadh beò agus ruigsinneachd air leth air barrachd air 200 Com-pàirtichean foillseachaidh earbsach.

Tha mòran phàirtean eadar-dhealaichte aig aplacaidean Android. Is e aon phàirt an cuideachaidh an cuideachaidh. Leigidh am pàirt seo dhut an susbaint san tagradh agad a cho-roinn. Faodaidh tu an clas tar-ghnìomhachd a rèiteachadh anns a 'phròiseact Android agad, An uairsin cleachd an cuid cuideachaidh gus dàta a chuir bho aon ghnìomh gu fear eile.

Kotlin

Ma tha thu a 'feuchainn ri ionnsachadh mar a nì thu aplacaidean Android, Bidh thu airson Kotlin ionnsachadh. It’s an extremely flexible language and is supported by Android Studio. If you’re looking for a way to develop apps faster and easier, Kotlin is the way to go.

Kotlin compiles to Java bytecode, so your application will look and feel just like a Java one. It’s compatible with AVDs, which means you can install Kotlin applications without having to rewrite your existing applications. Gus tòiseachadh, simply create a new Kotlin file by Control-clicking your app directory and then selecting “New Kotlin Activity”.

After you have installed Kotlin, you should delete the Java directory. Kotlin applications will run on the Android platform just like Java applications. If you’re not familiar with Kotlin, you can download the Android Studio app to learn how to program it.

Is e roghainn math eile airson prògramadh App Android XML, Cànan Markup. Tha seo nas sùbailte na java agus faodaidh tu an aplacaid agad a sgrìobhadh ann an XML, Luchdaich suas e gu innealan Android, agus dèan deuchainn air ann an àrainneachd fhìor. A bharrachd, Tha stòradh a-staigh aig Android Glaodach a-staigh airson faidhlichean agus stòran-dàta beaga.

Amas-C

Is e amas-c aon de na cànanan prògramaidh as cumhachdaiche airson Android. Fhad 's nach eil e cho cumhachdach ri swift, Tha e nas fhasa ionnsachadh agus faodar a chleachdadh gus aplacaidean nas luaithe a chruthachadh. Ma tha thu a 'coimhead ri bhith ag ionnsachadh mar a nì thu còd airson Android, bu chòir dhut tòiseachadh le amas-c. Tha gu leòr de chùrsaichean air-loidhne a chuidicheas tu gus tòiseachadh.

Faodaidh tu amas-c ionnsachadh - C le bhith a 'leantainn pròiseact eisimpleir. Faodaidh tu cuideachd amas-C a chleachdadh - C gus do gheama fhèin a chruthachadh. Tha amas-C a 'faighinn taic bhon dà chuid an iphone agus Android NDK, agus faodaidh tu a chleachdadh gus an còd C a chlàradh gu dìreach. Gheibh thu cuideachd na dh 'eisimpleir pròiseactan airson Android.

Bidh Android a 'toirt seachad frèam tagraidh beairteach agus leabharlannan API a tha ga dhèanamh furasta aplacaidean is gheamannan ùr-ghnàthach a chruthachadh. Fhad 's a tha Swift na chànan tòiseachaidh, Tha amas-c na chànan cumhachdach airson luchd-leasachaidh Android agus iOS. Tha an cur gu bàs as luaithe, Dìon, agus tha an staid neo-àbhaisteach de eadar-ghnìomhachd cudromach airson a bhith a 'cruthachadh tagraidhean freagairteach agus le cromadh. Fhad 's a tha Swift agus Irise - C an dà chuid oop, Tha e cudromach fios a bhith agad dè am fear as fheàrr a tha a 'freagairt air na feumalachdan agad.

A bharrachd air swift agus amas-c, Bidh Apple cuideachd a 'tabhann luath. Feumar an àrainneachd leasachaidh Xcode a chuir a-steach air mac no coimpiutair le Apple. Is e na leabhraichean naidheachd na coimpiutairean a thathar a 'moladh airson Xcode a chuir a-steach. To get access to Apple Developer’s account, you will need to register with your e-mail address and pay 82 EUR annually.

Sguab

There are several different ways to learn Swift for Android. One way is by signing up for an online course. Some free courses will give you the basics of the language, while others will cover more advanced topics. There are also a variety of kostenpflichtig courses available. If you are an experienced programmer, you can also learn to code in Swift.

Whether you want to learn the language for Android, iOS, no an dà chuid, you must first understand the technical differences between these platforms. These differences are summarized in the table below. While it may seem like it would be better to create two separate apps to cater to each platform, this isn’t always the best option. One possible solution is Cross-Platform Programming, otherwise known as writing once and running anywhere.

In addition to Swift, you can also use other languages for Android development. Mar eisimpleir, you can use Java, C++, or Python to create an Android app. Both of these languages allow you to create a variety of different types of apps. You can learn how to use them using tutorials and a variety of other resources.

Sreath XML

XML is one of the most widely used formats in Android app development. Its benefits include being platform-independent and user-friendly. Anns an artaigil seo, we’ll take a closer look at this popular format. XML documents are basically tree structures with multiple elements, or root elements. Each element can have multiple values, or variables.

A string is the data-storing unit of an XML-Zeichenkett, agus tha eileamaid anns a h-uile cealla san raon. Is e sreath a chanar ris an eileamaid seo, agus tha fiosrachadh ann mu ionnstramaidean ionmhais. Tha xml-sreangan air an parsadh agus air an taisbeanadh gu neach-cleachdaidh a 'cleachdadh dom-schnittstele.

Faodar XML-aktienakald a leughadh leis an dòigh ùr ReadxmlakstiedDatendad. Tha an dòigh seo a 'pasgadh sreang XML agus a' tilleadh sreath-sròin anns a bheil am fiosrachadh ionmhasail buntainneach. Tha seo an uairsin an uairsin air a thoirt don dòigh air an dòigh air-stad, a tha air a thoirt a-steach gu fèin-ghluasadach nuair a tha gnìomh asyncronous air crìochnachadh.

Dòigh cuairt-beatha

Anns a 'cheist-beatha-modh-obrach airson prògramadh App Android, Bidh gach gnìomh a 'tòiseachadh agus a' crìochnachadh. Bidh Android a 'cleachdadh a' bheatha-beatha seo gus goireasan a riaghladh agus dèanamh cinnteach gu bheil an tagradh a 'freagairt gu sgiobalta ri iarrtas neach-cleachdaidh. Bidh aplacaidean nach eil a 'leantainn beatha-beatha gu tric a' toirt seachad droch eòlasan cleachdaiche agus rudan a tha gun fheum.

Ann an gnìomhachd Android, an t-Sabaid() tha an dòigh air a ghairm nuair a thèid an gnìomhachd a 'stad no air a thoirt gu crìch. Tha an dòigh seo air a chleachdadh gus dàta a shàbhaladh san tagradh, luchd-èisteachd a chlàradh, agus brosnaich ùrachaidhean UI. Thathas cuideachd air a ghairm cuideachd nuair a bhios an neach-cleachdaidh a 'brùthadh a' phutan dachaigh.

Tha modh-beatha-modh-obrach na phàirt deatamach de phrògramadh App Android. Rè atharrachadh ann an rèiteachadh, Tha suidheachadh gnìomhachd na h-atharrachaidhean gnìomh ag atharrachadh. Bidh seo ag atharrachadh coileanadh an tagraidh. Uime sin, Tha API sònraichte aig Android airson stàite a ghlèidheadh ​​rè atharrachaidhean rèiteachaidh.

Leighead-beatha-modh-obrach airson Prògramadh App Android a 'toirt cothrom dhut tòiseachadh air gnìomhachd a thòiseachadh agus stad a chuir air gnìomhachd. Faodar gnìomhachd a thòiseachadh tro ghnìomhachd sam bith clàraichte air an inneal. Bidh gnìomhachd sònraichte aig a 'mhòr-chuid de thagraidhean. Nuair nach eil an aplacaid gnìomhach, Faodaidh an Android OS feuchainn ri ath-thòiseachadh aig a 'ghnìomhachd mu dheireadh a dh' fhosgail. Mura tachair seo, the OS can pause the activity and reclaim its memory.

Google App Inventor

Google App Inventor was originally developed by Hal Abelson, innleadair bathar-bog aig Google Labs. Bha lèirsinn aige air leasachadh app android a dhèanamh nas fhasa don neach-cleachdaidh cuibheasach. Bha an amas a 'cruthachadh an-asgaidh, Inneal a tha furasta a chleachdadh a 'cleachdadh a' chleachdaiche a chuidicheadh ​​luchd-leasachaidh a thogail aplacaidean mòra gun chuideachadh bho àrainneachdan leasachaidh daor.

Leigidh an neach-cleachdaidh gnàth-aghaidh cleachdaiche grafaigeach a 'leigeil le bhith a' sgrùdadh agus a 'togail thagraidhean a' cleachdadh co-phàirtean a chaidh a thogail agus blocaichean loidsigeach. An dèidh app a thogail, Faodaidh tu deuchainn a dhèanamh air air inneal brìgheil gus faicinn mar a tha e ag obair agus dè na gnìomhan a tha e a 'coileanadh.
