Eclipse Android isn't generated R.java

Question

It's my first time developing for android. I'm trying to develop in eclipse environment, but I have a problem. The class R.java isn't generated. I've already tried everything like function clean or refresh->clean, and reinstall eclipse. Maybe the problem can be in my layout:

My layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

</RelativeLayout>

There are many reasons why [R cannot be resolved - Android error](http://stackoverflow.com/questions/885009/r-cannot-be-resolved-android-error)... like importing `android.R` and a typo in your XML. — Sam, Mar 21 '13 at 18:19
Also check your imports, if it contacts android.R.java then remove it from the imports. — Pragnani, Mar 21 '13 at 18:21

I assume you mean it isn't being regenerated? This problem comes up a lot in Eclipse. Just delete the existing R.java and it will regenerate correctly.

Or do you mean you have no R.java at all?

No. My Eclipse isn't generated R.java. Instead of it's generated this class: /** Automatically generated file. DO NOT MODIFY */ package com.example.hello; public final class BuildConfig { public final static boolean DEBUG = true; } – André Paris Mar 21 '13 at 18:22
The BuildConfig class should be generated additionally to the R class. You can check the DEBUG constant from code to see if it's compiled with or without debugging. – Ridcully Mar 21 '13 at 18:26
How did you create this project? The New Android Application wizard always creates an R file by default. – j__m Mar 21 '13 at 18:29
I created my project normally, new->android project. Nobody knows how to solve my problem.. =/ I want to develop in Eclipse, but just my Netbeans is working... – André Paris Mar 21 '13 at 20:59
