I have been writing this code and it is running properly before, but now its giving exception. If there is anything i have to do in Manifest file or anywhere else please help. I want to show a Blank screen with a drawable set behind and after sleep time of 5000 it must transfers the activity.
package com.example.app3;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TextView;
    public class Welcome extends Activity {
        TextView tv;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.welcome);
            tv = (TextView)findViewById(R.id.textView1);
            Thread t1 = new Thread(){
                public void run(){
                    try {
                        Thread.sleep(7000);
                        finish();
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }finally{
                        Intent inn = new Intent(Welcome.this,MainActivity.class);
                        startActivity(inn);
                    }
                }
            };
            t1.start();
}
}
