java - "No activity found to handle intent" error -

i'm beginning develop , tried following set of tutorials on youtube. got confused after trying follow tutorial 1.8.

what happens launch application (using emulator), opens application. goes splash.xml screen, background, 5 seconds. then, it's suppose go mainactivity.java screen, main screen. unfortunately, after showing 5 seconds of splash screen, tells me application has stopped.

androidmanifest.xml:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.eduardopelaez.minecraftforums"     android:versioncode="1"     android:versionname="1.0" >      <uses-sdk         android:minsdkversion="8"         android:targetsdkversion="17" />      <application         android:allowbackup="true"         android:icon="@drawable/ic_launcher"         android:label="@string/app_name"         android:theme="@style/apptheme" >         <activity             android:name=".mainactivity"             android:label="@string/app_name" >             <intent-filter>                 <action android:name="android.intent.action.main" />                 <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>     </application>  </manifest> 

splash.xml (which shown 5 seconds after opening application):

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:background="@drawable/minecraft_wallpaperrepeating"     android:orientation="vertical" >      </linearlayout> 

mainactivity.java (which suppose come after splash.xml, crashes):

package com.eduardopelaez.minecraftforums;  import android.app.activity; import android.content.intent; import android.os.bundle;  public class mainactivity extends activity {      @override     protected void oncreate(bundle travisisawesome) {         super.oncreate(travisisawesome);         setcontentview(r.layout.splash);         thread logotimer = new thread() {             public void run() {                 try {                     sleep(5000);                     intent menuintent = new intent(                             "com.eduardopelaez.minecraftforums.mainactivity");                     startactivity(menuintent);                 } catch (interruptedexception e) {                     // todo auto-generated catch block                     e.printstacktrace();                 }                  {                     finish();                 }             }         };         logotimer.start();     }      @override     public boolean oncreateoptionsmenu(android.view.menu menu) {         // inflate menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.main, menu);         return true;     }  } 

intent menuintent = new intent(                                  mainactivity.this, mainactivity.class);                 startactivity(menuintent);
