Quid debes scire de Android App Development

Si vos es interested in doctrina de Android app development, venisti ad locum dextrum. In hoc articulo, youll scire Java, Kotlin, Fragmentation, et indigena user interfaces. Youll 'etiam discere de Android SDK, GDR, et fragmenta. in votis est, Hoc notitia mos succurro vos satus aedificium apps in nullo tempore. Nisi te surrexit quaedam quaestiones, Noli timere rogare!

Java

Si develop Android app're paras, Tunc Java ut sit idealis lingua ut. Java est summus gradu programming language, et Syntax propinqua ut humana linguarum. Igitur, Java applications sunt flexibile et scalable, Et veni cum dives bibliotheca de default Design exemplaria et optimum exercitia. Java etiam aperta fonte, Quod est possibile ut reusable codice in modular projects. Java enim Android app development est unus ex maxime commune programming linguis Android app development.

Si vestri 'Considerans Java ad Android app development, Youll 'postulo intelligere differentias inter hoc programming lingua et Kotlin. Si vestri 'Considerans Java ut primum arbitrium, ut in animo quod suus 'adhuc plus 20 Annorum maior quam Kotlin. Tamen, Youll 'postulo discere utrumque linguarum, si vis ut maxime de hac platform. Ut etiam vis ad aedificare app est utitur et linguis.

Java habet multa commoda per Kotlin, Sed suus 'etiam paulo durius discere. Dum Java est late in Android Development, Kotlin est minus late usus. Dum Kotlin est facilius discere quam Java, Suus 'a bonus choice pro Android Development. Kotlin est facilius discere quam Java et est Lingua Google suadet enim Android Development. Etiam providet magis auxilium ad Android Development.

Kotlin

Si vos es planning ut kotlin programming language ad Android app development, Sunt pauca scis primum. Dum offerat plures commoda, Non eget aliquantulus of discendi tempore. Non est facile ut alius programming linguae et requirere rewriting projects et optimizing eos. Tum iterum, Si gravi circa creando interfectorem app, Et erit paratus ad occupari aliquam provocationem quae est via tua. Alius res vos meminisse quod Kotlin faciam processus exsequendam tuum project citius.

Quia eius introductio ad Google I / O colloquium in 2017, Kotlin habet lucrata multo popularis et est cito pasce Java ut maxime popular programming linguae pro Android. Hoc novum linguam est brevis et minus proni ad boilerplate codice. Etiam reduces opus extensive temptationis et sustentationem de app, unde minus bugs et minor inruerit. Comparari Java, Kotlin codice multo minor et concisa.

Dum Java iam diu fuisse fundamenta Android Products, The New Lingua Kotlin fecit multis developers Rethink eorum aditus ad creando apps. Kotlin creatus est a Russian startup jetbrains et ædificatur in Java Rectum Apparatus. Est typus, Eget programming lingua quae decurrit in Java Rectum Apparatus. Finis Kotlin est providere citius compile tempora et ad apps facillimus ponere.

Fragmentation

Per Fragmentation in Android App Development concedit developers ad usum callbacks ut administrare lifecycle fragmentorum. Haec modi sunt communiter in Android Apps, et includit oncreate, onStart, in Sergii, ondestroy, et Onresume. Using callbacks potest facere fragmenta modularis, standalone, et reusable components. Non potest etiam auxilium tuum app Respondeo ad diversas callbacks et intenciones, et argumenta ad parens operatio initialization.

In Android app development, A fragmentum est fragmentum de activitate scriptor user interface. Fretus in screen magnitudinem machinam, Fragmenta sit independens et modularis. Fragmenta sunt reusable inter actiones, et potest compositae creare unum actionem. Autem, Fragmenta potest reddi per diversas screens. Fragmenta facit eam facillimus ad developers ad ponere in app scriptor codice.

Per fragmenta in Android app development eliminat quaestionem de non-null ui elementa. Pro fragmenta possidebunt ab actione, Vos can creare separata fragmenta ad invicem formam factor. Fragmenta tantum habent ui officia specifica ad quod forma factor, Itaque actio potest delegare ui responsibility ad opportunitate fragmentum. A fragmenta potest habere multiple components, ut bullarum vel menus.

Fragmenta in Android app development est ongoing exitus. Multi mobile fabrica fabrica sunt customizing Android OS ad fit specifica fabrica. Hoc ducit ad plures differences in codice, quae significat quod diversis versions of applicationem et run aliter. Nam developers, Hoc potest esse ingens provocatione, Sed Google est opus figere hoc problema. Per offering Android Compatibility Program, Developers potest facile filter quod cogitationes et versions possunt develop pro.

Native user interfaces

Native user interfaces in Android app development potest creata per incorporating Java programming et XML. Android views providere structural mores, Dum viewGroups sunt patria components potest addere consilio elementa vel vexillum mores. Exempli gratia, Et PageViewer ViewGroup providet Horizontalis Swiping in pasco, Similia Googles App. Et applicationem potest uti utriusque viewgroups ut suus 'securus utor.

Dum plurimi commoda ad effectum effectum adscribendas Hybrid consilio, Suus 'non semper maxime cost-effective solution. Multi iOS developers invenire quod sumptus de developing an app pro utroque platforms est prohibitoria. Fortunate, Pauci potens frameworks facilius ad effectum deducendi patria UI consilio Android. Sed Ui Designers oportet considerare quod ui guidelines sunt diversa pro iOS et Android. A consuetudo Android implementation ut requirere magis conatus, Maxime si app est scriptor primaria metam est ad target iPhone users.

Android users potest accedere applications per hardware interface et OS scriptor user interface (UI). UI est visual repraesentatio certo ratio, ut domum screen et notification panel. Et UI est tam hardware et software et potest includere applicationem Fenestra, Paginae textus, Mobile App Screens, et Gauges et luminaria. Native UIs also offer the advantage of being fully functional on a variety of devices.

Testis

There are two main types of testing an Android app: unit tests and integration tests. Unit tests are smaller pieces of code that verify functionality; end-to-end tests run on a real device, while integration tests verify how the app works across all modules. Integration tests should account for around 20% of the total number of tests. If you’re a new developer, it can be helpful to use a testing codelab to learn more about this process.

You’ll need to create an APK before you can start writing tests. Instrumented tests run on the device and require that you include the Android framework, which is available through the Android ADB. To make sure everything works, you’ll want to make sure you have the required test libraries. If your test library doesn’t include these, you’ll have trouble integrating it. Fortunate, instrumented tests are incredibly useful and are easy to use.

To run tests locally on your development machine, use Robolectric. This framework is designed to run on a local host and follows best practices for mocks. Robolectric is particularly useful for testing Android apps because it allows you to run tests on Android dependencies and is fast and clean for unit testing. It can also simulate runtime on Android 4.1 and supports community-maintained fakes. Hoc modo, you can test your code without an emulator.

Distribution

There are many marketing channels for Android apps. The first and foremost is the Google Play. Hoc marketplace est maxima eiusmodi et concedit developers distribute sua apps in variis modis. In addition ad app et Google Play, Android habet pauci alias distribution channels. Si vestri app aims ut pervenire maxima auditorium, Esset utilem explorare omnibus. Sunt etiam variis aliis modis distribute tua app, Comprehendo mobile Marketplaces velut Amazon app, iTunes copia, et fabula copia.

Semel Android app est completum, Vos can distribute ut vestri testers. Quia haec, Vos mos postulo ut creare simplex frontend quod enable testers ut install in app. Cum autem testers sunt downloaded in app, Debent ad rationum vel aperire email in mobili cogitationes. Potest esse tempus consumens et ad defuit mutationes. Vel:, Vos can utor crucem-suggestus testis distribution.

Alius beneficium de Android app development est quod facile est customize. Quia Android est altus customizable platform, Developers facile scissor in occursum negotium necessitatibus. Praeterea, et Android, Ibi suus non uno distribution platform, Ita developers potest creare multa distribution channels ad eorum apps. Hoc modo potest ad plures scopum audientibus, Quod est magnus utilitatem aliquam rem. Et, Cum platform est aperta fonte, Hoc dat manufacturers magis optiones et libertatem creare Android Apps.
