title: Application not working, beginner
body: <p>i am fairly new to android programming and usually find my answers to my problems by searching, but this one i just cant and its very confusing.
      The code itself doesn't show any signs of problems, well i do get 2 java exception breakpoints but i dont know how to fix those as they are "unknown"but when i run it on the emulator it says the application has stopped unexpectedly force close. I try to debug it but i dont know how to do it that well. any way here are the codes btw the app is just a test all it to do is have buttons that take me to other "pages" and back.  I would appreciate any help.</p>
  
  <p>Main java file</p>
  
  <pre><code>package com.simbestia.original;
  
  import android.app.Activity;
  import android.os.Bundle;
  import android.view.View;
  import android.widget.Button;
  
  public class original extends Activity implements View.OnClickListener {
      Button button1, button2;
  
      /** Called when the activity is first created. */
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.main);
  
          button1 = (Button) findViewById(R.id.pagetwo);
          button2 = (Button) findViewById(R.id.main);
  
          button1.setOnClickListener(this);
          button2.setOnClickListener(this);
      }
  
      @Override
      public void onClick(View v) {
          switch (v.getId()) {
          case R.id.pagetwo:
              setContentView(R.layout.pagetwo);
              break;
          case R.id.main:
              setContentView(R.layout.main);
              break;
          }
      }
  }
  </code></pre>
  
  <p>Main xml</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  &gt;
  &lt;TextView  
  android:layout_width="fill_parent" 
  android:layout_height="wrap_content" 
  android:text="@string/hello"
  /&gt;
  &lt;Button android:text="pagetwo" android:id="@+id/pagetwo"              android:layout_width="wrap_content" android:layout_height="wrap_content"&gt;&lt;/Button&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>Well here is what i change the code to this one is just one button but it works with multiple and i made a class for every page...</p>
  
  <pre><code>package com.simbestia.test;
  
  import android.app.Activity;
  import android.content.Intent;
  import android.os.Bundle;
  import android.view.View;
  import android.widget.Button;
  
  public class main extends Activity {
  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
  
      Button mainmenu = (Button) findViewById(R.id.mainmenu);
      mainmenu.setOnClickListener(new View.OnClickListener() {
          public void onClick(View view) {
              Intent myIntent = new Intent(view.getContext(),  mainmenu.class);
              startActivityForResult(myIntent, 0);
          }
      });
  }
  </code></pre>
  
  <p>}</p>
