Android studio FATAL EXCEPTION: Thread

Question

У меня проблема с FATAL EXCEPTION: Thread

Я создал программу, принцип работы, такую ​​программу в режиме редактирования текста, я пишу любые слова, затем, когда я нажимаю кнопку Glide, gif начинает загрузку с URL, а gif начинает загружать анимацию лотереи после загрузки и начинает играть gif.

проблема заключается в том, что когда я запускаю программу и затем нажимаю на кнопку, программа выдает такой ошибка

когда я нажимаю на кнопку, этот код работает

public void getData(View view) {
    if(!checkConnection()) {
        Toast.makeText(this,"No internet connection",Toast.LENGTH_SHORT).show();
        return;
    }
    getApi();
    text = editText.getText().toString();

        constraintLayout.setVisibility(View.VISIBLE);
        lottieAnimationView.setVisibility(View.VISIBLE);
        textView2.setVisibility(View.VISIBLE);

        threadForAnim.start();

        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            public void run() {
                PlayGif();
            }
        }, 2000);
    }
    else Toast.makeText(this, "Please enter your question!", Toast.LENGTH_SHORT).show();
}

public void PlayGif(){
    Glide.with(this)
            .asGif().load(gif)
            .apply(new RequestOptions()
                    .error(R.drawable.ic_action_name))
            .listener(new RequestListener<GifDrawable>() {

                    return false;
                }

                @Override
                public boolean onResourceReady(GifDrawable resource, Object model, Target<GifDrawable> target, DataSource dataSource, boolean isFirstResource) {
                    Log.e("status", "gif loaded");
                    handler.removeCallbacks(threadForAnim);
                    lottieAnimationView.cancelAnimation();
                    lottieAnimationView.setVisibility(View.INVISIBLE);
                    textView2.setVisibility(View.INVISIBLE);

                    constraintLayout.setVisibility(View.VISIBLE);
                    textView3.setText(text);
                    textView3.setVisibility(View.VISIBLE);

                    Log.e("status", "removeCallbacks");
                    return false;
                }
            }).into(gifView);
}

class ThreadForAnim extends Thread{
    @Override
    public void run() {
        super.run();
        Log.e("status", "run");
        lottieAnimationView.setAnimation("data.json");
        lottieAnimationView.loop(true);
        lottieAnimationView.playAnimation();
    }
}

Помогите создать эту программу благодаря большое
