My Android app splash screen launches in the android emulator, but then the actual app never shows

When i try to run my app, the splash screen comes up correctly, and right after it closes, a message pops up that says "Unfortunatly, First app has stopped working" I've tried a ton of different solutions I've found but i believe in my case, it's a problem with my code after testing a new "Hello World" app within the emulator. Here's a copy of my androidmanifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.examle.firstapp"
    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=".Splash" android:label="@string/app_name" >
            <intent-filter>
                <action android:name="com.example.firstapp.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity
            android:name=".MainActivity" android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAINACTIVTY" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>

    </application>

</manifest>

Here is what comes up in log cat after trying some of the solutions

I'm really quite new to android programming, so if you could be specific when assisting me it would be greatly appreciated.

In this case, the error lies in your manifest. The package name must be:

package="com.example.firstapp"

Also, for MainActivity, try to remove this:

<action android:name="android.intent.action.MAINACTIVTY"\>

You can two step follow: 1. Uninstall previous (same) apps if install in your android phone. 2. Delete gen + bin folder then again after a few time run your apps in your android phone. Thanks

 public class SplashScreenActivity extends Activity {
    /** Called when the activity is first created. */
    @Override

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Timer timer=new Timer();
        timer.schedule(new MyTask(), 5000);
    }


    class MyTask extends TimerTask{

        @Override
        public void run() {
            Intent intent=new  Intent(SplashScreenActivity.this,SecondActivity.class);
            finish();
            startActivity(intent);
        }

    }

}

in manifest

<intent-filter>
  <action android:name="android.intent.action.MAIN" /> 
  <category android:name="android.intent.category.LAUNCHER" /> 
  </intent-filter>`enter code here`
  </activity>
  <activity android:name=".SecondActivity" />

I believe that it can't find your main activity because you have spelled the example wrong in your manifest on the line:

package="com.examle.firstapp"

should be:

package="com.example.firstapp"

Assuming Splash in the default main activity to be launched. Your manifest should be

Your package name should be

 package="com.example.firstapp"

Activity 

 <activity
        android:name="com.example.firstapp.Splash"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>    
  <activity
        android:name="com.example.firstapp.MainActivity"  
        android:label="@string/app_name" >
         <intent-filter>
            <action android:name="com.example.firstapp.MainActivity" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

If you have explicit intents you can skip the intent filter

     <activity
        android:name=".MainActivity"  
        android:label="@string/app_name" >
    </activity>
