Application crashes when it tries to launch Intent

I have a splash screen that i want to run before my main app screen. However, when the timer ends, the applicaiton crashes. Any ideas on why this happens? Thanks in advance.

Below is the referenced code

public class Splash extends Activity {

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

        Thread timer = new Thread() {
            // Whatever is enclosed in the {} of method run(), runs when we
            // start the application
            public void run() {
                try {
                    sleep(2000);

                } catch (InterruptedException e) {
                    e.printStackTrace();

                } finally {

                    Intent openMainScreen = new Intent("com.package.Main_Screen");
                    startActivity(openMainScreen);

                }
            }
        };

        timer.start();
    }
}

Write below code

Intent openMainScreen = new Intent(this, MainActivity.class);
startActivity(openMainScreen);

instead of

Intent openMainScreen = new Intent("com.package.Main_Screen");
startActivity(openMainScreen);

And declare your MainActivity into Androidmanifest.xml file.

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

        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</activity>

it will solve your problem.

You are calling startActivity from different Thread.You have to run it from UI thread.What you are trying to achieve can be done easily by

    public class Splash extends Activity {
        Handler handler;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_splash);
            handler = new Handler();
            handler.postDelayed(new Runnable() {
                public void run() {
                    Intent openMainScreen = new Intent(Splash.this,
                            Main_Screen.class);
                    startActivity(openMainScreen);

                }
            }, 2000);
        }
    }

You have to call like this 

Intent openMainScreen = new Intent(ClassName.this, MainActivity.class);
startActivity(openMainScreen);

And you have to register it in Manifest file

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

Why don't you simply use this kind of Intent, 

Intent openMainScreen = new Intent(Splash.this,Main_Screen.class);
startActivity(openMainScreen);

And also make sure you you have added the Activity in your manifest like this, 

<activity android:name=".Main_Screen">
 </activity>
