Did you post the complete Splash.java file. Because the code you posted is incomplete
Code:
package com.example.david.davidsmotivation;

import android.widget.TextView;
public class Splash extends AppCompatActivity {

Typeface myTypeface = Typeface.createFromAsset(getAssets(), "Papyrus.ttc"); [COLOR="RoyalBlue"]// Is this correct ? Fonts are generally '.ttf' files[/COLOR]
TextView myTextview = (TextView) findViewById(R.id.textView1);
myTextview.setTypeface(myTypeface);

Can help me to see what's wrong? Thank you !!!!
I can't read the all code, it's too long, but ai think that you want to access for example array [5], but array length is smaller.
