How to access lottie files outside res folder programatically

Question

I don't know this is a duplicate question or not, but i tried to search similar question according to this.

I want to access the file that located outside /res folder programatically. I already know if we want to access /res folder, then we just call it's id like getString(), getDrawable() etc.

But in my case, I want to access anim_empty.json programatically. How to do that?

You can use `getAssets().open()` method from `Context` class which will provide you `InputStream` object. I.e. `context.getAssets().open("file name");` — Jeel Vankhede, Feb 12 '19 at 05:58

Try following method for accessing JSON data:

public static String loadJSONFromAsset(Context mContext, String fileName) {
    String json;
    try {
        InputStream is = mContext.getAssets().open(fileName);
        int size = is.available();
        byte[] buffer = new byte[size];
        is.read(buffer);
        is.close();
        json = new String(buffer, "UTF-8");
    } catch (IOException ex) {
        ex.printStackTrace();
        return null;
    }
    return json;
}

Modify the method according to your usage..

In the truth, i just wanted to call the Lottie animation files, i thought that i need to write script like the answer above but all i need is just these (Getting Started With Animations in Android Using Lottie — Kotlin and enter link description here):

    lottieAnimationView = findViewById(R.id.empty_hstanim);
    lottieAnimationView.setAnimation("anim_empty.json");
    lottieAnimationView.playAnimation();

Thanks for the kind answer anyway!
