Animation screen works on phone but not tablet

Question

So Ive made my first animation screen for my phone, this works perfect, and now I wanted to try it out on my tablet, but it crashes. The tablet is a Lenovo TAB3 7 Essential / Samsung SM-T550 .

As you can see in the picture above it's line 34 setContentView(R.layout.activity_startscreen); the error occurs.

I've tried to Clean my project, but i think it might be in the .xml file?

The activity I showed Startscreen.java

public class Startscreen extends AppCompatActivity {

    private static int SPLASH_DURTION_OUT = 5000; // 5000ms = 5s

    //Views
    View first, second, third, fourth, fifth, sixth;
    TextView bottomTag;
    ImageView wrd;

    //Animations
    Animation topAnimation, bottomAnimation, middelAnimation;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.activity_startscreen);

        topAnimation = AnimationUtils.loadAnimation(this, R.anim.top_animation);
        bottomAnimation = AnimationUtils.loadAnimation(this, R.anim.bottom_animation);
        middelAnimation = AnimationUtils.loadAnimation(this, R.anim.middel_animation);

        first = findViewById(R.id.first_line);
        second = findViewById(R.id.second_line);
        third = findViewById(R.id.third_line);
        fourth = findViewById(R.id.fourth_line);
        fifth = findViewById(R.id.fifth_line);
        sixth = findViewById(R.id.six_line);

        wrd = findViewById(R.id.wrd);
        bottomTag = findViewById(R.id.tag);

        //Animation settings
        first.setAnimation(topAnimation);
        second.setAnimation(topAnimation);
        third.setAnimation(topAnimation);
        fourth.setAnimation(topAnimation);
        fifth.setAnimation(topAnimation);
        sixth.setAnimation(topAnimation);

        wrd.setAnimation(middelAnimation);
        bottomTag.setAnimation(bottomAnimation);

        //Splash Screen
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                Intent intent = new Intent(Startscreen.this, Home.class); //Home = Mainactivity
                startActivity(intent);
                finish();
            }
        }, SPLASH_DURTION_OUT);

    }
}

This is my Manifest

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.wrd">

发现问题了，我所有的.png图像都在我的Drawable-v24文件夹中，而不是Drawable ，所以现在修复了！
