Вот мой код действия, которое я хочу запустить первым: 

package com.example.adamf.authtest;

import android.content.Intent;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.Html;
import android.view.View;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.TextView;

import org.w3c.dom.Text;

public class SplashActivity extends AppCompatActivity {

private ViewPager mSlidePager;
private LinearLayout mDotLayout;

private Button mNextBtn;
private Button mBackBtn;

private TextView[] mDots;

private SliderAdapter sliderAdapter;

private int mCurrentPage;
private int Check = 0;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState); setTheme(R.style.NoActionBarCustom);
    setContentView(R.layout.activity_splash);

    mSlidePager = (ViewPager) findViewById(R.id.slideViewPager);
    mDotLayout = (LinearLayout) findViewById(R.id.dotsLayout);

    mNextBtn = (Button) findViewById(R.id.nextBtn);
    mBackBtn = (Button) findViewById(R.id.prevBtn);

    sliderAdapter = new SliderAdapter(this);
    mSlidePager.setAdapter(sliderAdapter);

    addDotsIndicator(0);

    mSlidePager.addOnPageChangeListener(viewListener);

    //OnClickListeners
    mNextBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            mSlidePager.setCurrentItem(mCurrentPage + 1);

            Check = Check + 1;
            if(Check == 3)
            {
                Intent intent = (new Intent(SplashActivity.this, LoginActivity.class));
                startActivity(intent);
            }
        }
    });

    mBackBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Check = Check -1;
            mSlidePager.setCurrentItem(mCurrentPage - 1);
        }
    });
}

public void addDotsIndicator(int position){

    mDots = new TextView[3];
    mDotLayout.removeAllViews();

    for(int i = 0; i < mDots.length; i++)
    {
        mDots[i] = new TextView(this);
        mDots[i].setText(Html.fromHtml("&#8226"));
        mDots[i].setTextSize(35);
        mDots[i].setTextColor(getResources().getColor(R.color.colorTransparentWhite));
        mDotLayout.addView(mDots[i]);
    }

    if(mDots.length > 0)
    {
        mDots[position].setTextColor(getResources().getColor(R.color.colorWhite));
    }
}

ViewPager.OnPageChangeListener viewListener = new ViewPager.OnPageChangeListener() {
    @Override
    public void onPageScrolled(int i, float positionOffset, int positionOffsetPixels) {

    }

    @Override
    public void onPageSelected(int i) {
        addDotsIndicator(i);
        mCurrentPage = i;

        if(i == 0){
            mNextBtn.setEnabled(true);
            mBackBtn.setEnabled(false);
            mBackBtn.setVisibility(View.INVISIBLE);

            mNextBtn.setText("NEXT");
            mBackBtn.setText("");
        }
        else if (i == mDots.length -1)
        {
            mNextBtn.setEnabled(true);
            mBackBtn.setEnabled(true);
            mBackBtn.setVisibility(View.VISIBLE);

            mNextBtn.setText("FINISH");
            mBackBtn.setText("BACK");
        }
        else
        {
            mNextBtn.setEnabled(true);
            mBackBtn.setEnabled(true);
            mBackBtn.setVisibility(View.INVISIBLE);

            mNextBtn.setText("NEXT");
            mBackBtn.setText("BACK");
        }

    }

    @Override
    public void onPageScrollStateChanged(int state) {

    }
};

}

Я пытаюсь запустить приложение с помощью этого заставки, а затем перейти на мою страницу входа в систему, но как только действие называется приложением, происходит сбой, и я понятия не имею, почему. Я не получаю ошибок в консоли, и я скопировал этот код из другого моего приложения, которое работает абсолютно нормально. Я попытался перенаправить свою регистрационную активность на экран-заставку, а также сначала запустить экран-заставку, но как только его назвали, приложение вылетает.

У меня вопрос, может ли кто-нибудь найти что-то не так с этим кодом и, возможно, с проблемой, почему он не запускается?

Я пытался использовать эмулятор так же, как и мой телефон, но происходит то же самое, поэтому он должен быть связан с кодом ...

Спасибо

В вашем SliderAdapter, в instantiateItem методе это: 

View view = layoutinflater.inflate(R.layout.activity_splash, container, false);

Должно быть: 

View view = layoutinflater.inflate(R.layout.slide_layout, container, false);
