From your logs I can only make the following comments, Following line says, something is wrong on line# 18 of your MainActivity class, check your code with tutorial code. There is always a link to working project code on the lower right bottom of the video tutorial (horizontally parallel to teacher's notes section), you can download that code, run it and cross verify with yours. ******Your logcat line**** 10:22:05.320: E/AndroidRuntime(1198): at com.example.crystalball.MainActivity.onCreate(MainActivity.java:18

The following line says something about class not found exception, maybe you have imported the wrong support library *******Logcat line***
E/AndroidRuntime(1198): java.lang.NoClassDefFoundError: android.support.v7.appcompat.R$styleable

Hope this helps.

Can you paste in your MainActivity code and let us know which line is line 18?

package com.example.crystalball;

import android.os.Bundle;
import android.view.LayoutInflater;

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction()
                    .add(R.id.container, new PlaceholderFragment())
                    .commit();
        }
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }

    /**
     * A placeholder fragment containing a simple view.
     */
    public static class PlaceholderFragment extends Fragment {

        public PlaceholderFragment() {
        }

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {
            View rootView = inflater.inflate(R.layout.fragment_main, container, false);
            return rootView;
        }
    }
