![]() In the constructor you assign an instance of your adapter to this property (note you don’t need to use new in Kotlin) and assign two things to rv_item_list - a LayoutManager (which is used for positioning), and an Adapter (which we’ve just created). So here you’ve defined the adapter as a lateinit variable - lateinit is telling Kotlin that you want to initialize this at some stage after creation, not the default in Kotlin classes - normally you have to initialize things immediately. Sebelumnya mungkin ada yang sudah buat CRUD java dengan Database mysql, nah saya akan membuat aplikasi CRUD ( Create ,Read ,Update, dan Delete ) juga tetapi dengan Android Studio yang berbasis mobile dengan database SQLite, di sini saya menggunakan Android Studio 2.1.2, oke mulai saja. For example, often you’ll see curly brackets used as function parameters:īuildscript It resembles other languages you may have seen but some things look off, often because it is so concise!ĭon’t panic - because it is so extensible there are many ways to write the same code, and many shortcuts that aren’t available in other languages. Here is the complete code if you rather go straight to the end.īefore we start, let’s talk a bit about Kotlin. If you don’t have any Android experience you should be able to follow along but you might have to Google a few things here and there. In order to access this database, you don't need to establish any kind of connections for it like JDBC,ODBC e.t.c. Fragments simplify the reuse of components in different layouts and their logic. Android devices exist in a variety of screen sizes and densities. A fragment encapsulates functionality so that it is easier to reuse within activities and layouts. ![]() SQLite supports all the relational database features. Fragment is a piece of an activity that enables a more modular activity design. Android comes in with built in SQLite database implementation. I’m going to assume you have some Java experience and have at least played around with creating an Android app. SQLite is a opensource SQL database that stores data to a text file on a device. Spring Boot is a great way to create a robust REST API with a minimal amount of code. In this tutorial, you’ll use Spring Boot for the API that powers your Android (+ Kotlin) mobile app. text-to-speech sqlite android-app optical-character-recognition ocr-recognition login-registration-app. ![]() The best way to start is by creating a complete app yourself, which you’ll do in this tutorial. An app with the functionalities of Optical Character Recognition and Text-to-Speech Conversion, along with the User Login and Registration using SQLite Database. Kotlin was recently given official Android support status by Google, but it remains difficult to understand for many developers.
