Question

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?

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.

How can I stop this problem and go to the next page?

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<?> 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);
                        }

                }

            });
        }


    }

on this page that we used person as activities but it doesn’t work.

Sometimes when you clean your project the R file disappears, I had the same issue.

The way I fixed it was:

• Make sure all the import android.R was removed
  -Clean again (if this doesn’t fix it, restart eclipse and try again)

Or

• Put the pointers to R file in comment f.e. // setContentView(R.layout.main);
• If all the pointers to R file are in comment, you should get only warnings in the file, and hopefully errors somewhere else.

• Fix the errors and then uncomment the pointers. Sometimes eclipse ignores some errors and drops the R file and then says nothing about it, which is annoying, but this will fix it. 🙂

• If this still doesn’t work, you can try create a new project and copy paste your code in it.
