現在ボタンを押すとアニメーションが表示されるようなプログラムを組んでいるのですが、ボタンを押してからアニメーションが表示されるまでの間に時間があり、スムーズにアニメーションが表示されません。ログを見てみると、`Skipped
108 frames! The application may be doing too much work on its main thread.`
や、`GC_FOR_ALLOC freed <1K, 1% free 23795K/23900K, paused 10ms, total 10ms`
などと表示されています。アニメーションの際の各画像サイズが大きすぎるのだと思うのですが、色々と調べて画像サイズを減らそうとしてみても、画像が荒くなったりと中々思うようにいきません。解決策としてはどういった選択肢をとればよいでしょうか？下記にコードを記します。すみませんが、宜しくお願いします。

```

    public class AnimationActivity extends Activity {
        private Activity mActivity = this;
        ImageView animationImageView;

            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_animation);
    
            animationImageView = (ImageView) findViewById(R.id.animation_imageview);
    
            animationConfig = new AnimationConfig(mActivity, animationImageView, 2000, 2000, 50);
            animationConfig.setAnimationFrame(R.drawable.slot_01);

Skipped 108 frames! The application may be doing too much work on its main thread
<https://tinypng.com/> で画像のサイズを圧縮してみてはいかがでしょうか？  
画像が荒くなることもないかと思います。
