With the evolution of Android development, several APIs and functions get deprecated over time to make way for more robust and flexible alternatives. One such deprecation that developers need to be aware of is the onBackPressed() method in Android. In Android, onBackPressed() was commonly used to handle back button presses within an activity. However, with the introduction of the Jetpack libraries and the emphasis on more structured navigation, this method has been deprecated. This blog will explore why onBackPressed() is deprecated and what the best alternative solutions are in Kotlin for handling back navigation. Why onBackPressed() is Deprecated The primary reasons for deprecating onBackPressed() include: Improved Navigation Architecture: Android Jetpack's Navigation Component provides a more consistent and predictable way to handle navigation, including back navigation. Lifecycle Awareness: Handling back...

In Laravel, you can call a REST API using the HTTP client provided by the framework. Laravel's HTTP client allows you to make GET, POST, PUT, DELETE, and other HTTP requests to external APIs. Here's how you can call a REST API in Laravel: Install Laravel (if not already done): If you haven't already set up a Laravel project, you can create one using Composer by running the following command: composer create - project -- prefer - dist laravel / laravel project - name Create a Controller (optional): You can create a controller to encapsulate the API call logic, but this step is not strictly necessary. You can also make API calls directly from your routes or other parts of your application. To create a controller, run the following command: php artisan make: controller ApiController Make an API Request: You can make API requests using Laravel's HTTP client, which is a fluent, expressive interface for making HTTP requests. Here's how you can make a simple GET request t...

  To insert multiple rows into a Room database in Android, you can follow these steps: 1. Set up Room Database: First, make sure you have set up your Room database correctly in your Android project. Define your Entity class, create a Database class that extends RoomDatabase, and set up your DAO (Data Access Object) interface. 2. Create Entity Class: Define an Entity class that represents the data you want to insert into the database. For example: 1 2 3 4 5 6 7 8 9 @Entity (tableName = "my_table" ) public class MyEntity { @PrimaryKey (autoGenerate = true ) public int id; public String name; public int age; // Add other fields and getters/setters as needed } Create DAO: Create a DAO interface with a method to insert multiple rows. For example: 1 2 3 4 5 @Dao public interface MyEntityDao { @Insert void insertAll (List<MyEntity> entities); } Initialise Database and DAO: In your application code, create an insta...

 The search functionality in android App is a very important feature of any list page. In this article I make a simple android application to describe the SearchView integration in Android with RecyclerView | Toolbar | Kotlin. Follow the steps- Step 1 :  First create a blank project in android studio with simple empty activity. Step 2 :  Use the below code in colors.xml file <?xml version="1.0" encoding="utf-8"?> <resources> <color name= "purple_200" > #FFBB86FC </color> <color name= "purple_500" > #FF6200EE </color> <color name= "purple_700" > #FF3700B3 </color> <color name= "teal_200" > #FF03DAC5 </color> <color name= "teal_700" > #FF018786 </color> <color name= "black" > #FF000000 </color> <color name= "white" > #FFFFFFFF </color> </resources> Step ...

 As a Native android developer, it is very difficult to parse a complex JSON in our application. Normally the rest api json structure is much complex to parse it using functions as getObject(), getString(), getBoolean() etc. So, In order to overcome this problem also for save time we use GSON. Many developers already know that, but here I give you a simple and short solution that, you can convert JSON to Kotlin Model class for any complex JSON within 5 seconds. So Just follow the guidelines- Okay, First you can add the gradle dependency of GSON implementation 'com.google.code.gson:gson:2.8.6' Now I can take a sample JSON, which I make model class and then parse. Below I mentioned the sample json- { "problems" : [ { "Diabetes" : [ { "medications" : [ { "medicationsClasses" : [ { "className" : [ { ...
