How to create custom animation in Android Studio?
Custom animation in Android refers to the ability to create and define animations that are unique and customized to specific needs and requirements. This means that instead of using the built-in animation effects provided by Android, developers can create their own animations that are tailored to their app’s user interface and brand.
Custom animations in Android can be created using a variety of techniques, such as defining animation properties in XML files, using Java code to define and control animations, or using third-party libraries to create more advanced and complex animations.
Examples of custom animations in Android include:
- A custom loading animation that uses unique graphics and movement patterns to match the app’s design and branding.
- A custom transition animation between different screens or activities in the app, which can be used to create a more seamless and engaging user experience.
- A custom gesture animation that responds to user touch or input, such as a swipe or pinch gesture, to provide visual feedback and enhance the app’s usability.
What is Lottie in android animation?
Lottie is an open-source animation library for Android, iOS, and the web that allows developers to easily add high-quality, scalable vector animations to their apps. Lottie animations are created in Adobe After Effects, exported as JSON files, and then rendered natively within the app using the Lottie library.
The main benefits of using Lottie in Android animation are:
- Scalability:Lottie animations are vector-based, which means they can be scaled up or down without losing quality or resolution. This makes them ideal for creating animations that need to look good on different screen sizes and densities.
- Performance:Lottie animations are lightweight and optimized for performance, which means they can be rendered smoothly and efficiently on a variety of devices and platforms.
- Interactivity: Lottie animations can be easily controlled and manipulated through code, which means developers can add interactivity and dynamic behavior to their animations.
- Cross-platform compatibility: Lottie animations can be created and used across different platforms, including Android, iOS, and the web, which makes them a versatile and convenient option for multi-platform app development.
Overall, Lottie is a powerful tool for creating high-quality, scalable, and interactive animations in Android apps, and it has become increasingly popular among developers as a way to enhance the user experience and add visual interest to their apps.
What is Library in android studio?
In Android Studio, a library is a collection of pre-written code and resources that can be used to add specific functionality to an Android app. A library typically contains Java code, XML files, resources such as images and layouts, and other assets that are designed to be reused across multiple apps.
Libraries can be developed by third-party developers or by the app developers themselves, and they can be added to an app project as a dependency. Once added, the library’s code and resources can be accessed and used in the app’s code, allowing developers to save time and effort by reusing existing code instead of writing everything from scratch.
There are several types of libraries in Android Studio, including:
- Android platform libraries: These are built-in libraries that are included with the Android operating system and provide core functionality, such as user interface elements and system services.
- Support libraries: These are a set of libraries that provide additional functionality and support for older versions of Android. They include libraries for app compatibility, design, and media playback, among others.
- Third-party libraries: These are libraries developed by third-party developers and can provide a wide range of functionality, such as networking, analytics, and image processing.
Android Studio provides tools and features to help developers manage and use libraries in their app projects, including the ability to add and remove dependencies, manage library versions, and configure build settings. Using libraries can save time and effort and help developers create high-quality, feature-rich apps more quickly and efficiently.
How to download Lottie animation Json file?
To download a Lottie animation JSON file, you can follow these steps:
- Visit the LottieFiles website at https://lottiefiles.com.
- Use the search bar to find an animation you like, or browse the categories to find one that fits your needs.
- Once you’ve found an animation you want to download, click on it to view its details page.
- On the details page, click the “Download” button.
- Choose the format you want to download the animation in. You can choose from Lottie JSON, Animated GIF, or After Effects Project.
- If you choose the Lottie JSON format, the animation JSON file will download to your computer.
Alternatively, if you have created your own animation in Adobe After Effects and exported it as a Lottie JSON file, you can simply save the JSON file to your computer and import it into your Android Studio project. You can then use the Lottie library to render the animation natively in your app.
How to past Lottie animation JSON In raw folder?
To add a Lottie animation JSON file to the “raw” folder in your Android app, follow these steps:
- In Android Studio, go to the “Project” view on the left side of the window.
- Expand the “app” folder of your app’s project structure and locate the “res” folder.
- Right-click on the “res” folder and select “New” > “Android Resource Directory”.
- In the dialog box that appears, select “raw” as the resource type and click “OK”.
- A new “raw” folder will be created under the “res” folder. Drag and drop your Lottie animation JSON file into this folder.
Alternatively, you can create the “raw” folder manually by right-clicking on the “res” folder and selecting “New” > “Folder” > “Raw Resource Folder”. Once you have created the “raw” folder, you can drag and drop your Lottie animation JSON file into it.
To access the Lottie animation JSON file in your code, you can use the following code:
LottieAnimationView animationView = findViewById(R.id.myLottie); animationView.setAnimation(R.raw.custom);
Replace “custom” with the name of your Lottie animation JSON file (without the file extension). The LottieAnimationView will automatically load the animation JSON file from the “raw” folder and display it in your app.
How to get dependancy for Lottie animation from github and implement it in android project?
Lottie is a popular animation library that allows developers to easily render After Effects animations natively on Android, iOS, and the web. Here’s how you can get the Lottie library from Github and integrate it into your Android project:
Add the following dependency to your app-level build.gradle file:
dependencies { implementation 'com.airbnb.android:lottie:4.2.0' }
There are two ways to add a Lottie animation to your Android project:
Method 1: Use the LottieAnimationView
You can use the LottieAnimationView class to display a Lottie animation in your Android app. Here’s an example:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
tools:context=".MainActivity">
<com.airbnb.lottie.LottieAnimationView
android:layout_width="300dp"
android:layout_height="300dp"
app:lottie_rawRes="@raw/custom"
app:lottie_autoPlay="true"
app:lottie_loop="true"
>
</com.airbnb.lottie.LottieAnimationView>
</LinearLayout>
Here, we’re using the LottieAnimationView class to display the animation, and we’ve set the lottie_fileName attribute to the name of the JSON file we downloaded in Step 2. We’ve also set lottie_autoPlay and lottie_loop to true to start and loop the animation automatically.
That’s it. Now run your application and you will the animation.
Method 2: Use the LottieDrawable
Alternatively, you can use the LottieDrawable class to programmatically display a Lottie animation in your app.
First, Modify your XML layout of your MainActivity.xml like this.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
tools:context=".MainActivity">
<com.airbnb.lottie.LottieAnimationView
android:layout_width="300dp"
android:layout_height="300dp"
android:id="@+id/myLottie"
app:lottie_fileName="custom.json">
</com.airbnb.lottie.LottieAnimationView>
</LinearLayout>
Now place the following code in your MainActivity.java.
package com.panrum.customanimation;
import androidx.appcompat.app.AppCompatActivity;
import android.animation.Animator;
import android.os.Bundle;
import com.airbnb.lottie.LottieAnimationView;
import com.airbnb.lottie.LottieCompositionFactory;
import com.airbnb.lottie.LottieDrawable;
public class MainActivity extends AppCompatActivity {
LottieAnimationView myview;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myview=findViewById(R.id.myLottie);
myview.setAnimation(R.raw.custom);
myview.playAnimation();
myview.loop(true);
}
}
That’s it! With these steps, you should be able to successfully integrate the Lottie animation library into your Android project.
