need your help!

I am new in Android and for some reason my app stopped working and crashes right on startup.

I am not sure if it is related but I've added maven to the project. Here's the error log:

here's the manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest
    xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.test"
    android:versionCode="1"

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

        <activity
            android:name="com.test.activities.SplashActivity"
            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:label="@string/title_activity_main_menu" >
        </activity>
    </application>

and here's the activity:

public class SplashActivity extends Activity{

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

        Thread StartTimer = new Thread(){
            public void run(){
                try {
                    sleep(2000);
                    Intent main = new Intent(SplashActivity.this, MainActivity.class);
                    startActivity(main);
                    finish(); //kills the current activity
                }
                catch (InterruptedException ex){}
            }       
        };
        StartTimer.start();
    }
}

As I know Maven build systems waiting some pathes, check you project, your sources should be located somewhere like:

/src/main/java/com/test in your case.

Is your project have such structure?

And also I recommend to name groupid as "com.test"
