R.java android lost
<p>I lost R.java class when I clean my project.  So please how can I get it back?  Cause R.java define automatically in gen. Is there any way to do that? </p>

<p>I have imported a package to my project and I use it in project classes and pages but when I navigate to a page use a package the app gives a waiting and it still waiting.</p>

<p>How can I stop this problem and go to the next page? </p>

<pre><code>public class HomePage extends Activity {    
    @Override
        protected void onCreate(Bundle savedInstanceState) {
            // TODO Auto-generated method stub
            super.onCreate(savedInstanceState);
            setContentView(R.layout.person);
            Carousel car=(Carousel) findViewById(R.id.carousel);

            car.setOnItemClickListener(new OnItemClickListener(){

                public void onItemClick(CarouselAdapter&lt;?&gt; parent, View view,
                        int position, long id) {
                    // TODO Auto-generated method stub
                    if(position==0){
                        Intent i=new Intent(HomePage.this,StudentInformationActivity.class);

                        startActivity(i);
                        }else if(position==1){
                            Intent i=new Intent(HomePage.this,PersonalProfileActivity.class);
                            startActivity(i);
                        }
