Errors starting with Eclipse

Question

I am new with JavaScript and Developement on Android. I installed Eclipse but I can't even run the "Hello World" program, included when you created a new project !

Please help me, I spent the two last days installing this IDE (even tried Android Studio), but there is always the same error :

Could not find Chwet.apk!

And there seems to be an error with the "R", like in setContentView(R.layout.activity_main)

Here is my code :

package com.example.chwet;

    import android.os.Bundle;
    import android.app.Activity;
    import android.view.Menu;

    public class MainActivity extends Activity {
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
        }

        @Override
        public boolean onCreateOptionsMenu(Menu menu) {
            // Inflate the menu; this adds items to the action bar if it is present.
            getMenuInflater().inflate(R.menu.main, menu);
            return true;
        }
    }

Try to clean your project go to Project menu in eclipse and clean your project and let me know whether the error is gone or not. — InnocentKiller, Jan 31 '14 at 11:10

Did you mean "I am new to Java and Eclipse"? Can you start simple Java applications (non-Android) from within eclipse? Do you have the JDK installed or just the JRE? What does the Eclipse error log say? — Axel, Jan 31 '14 at 11:17
I am new to both Java and Eclipse. The error log says : "R cannot be resolve as a variable" — Nickel_Chrome, Jan 31 '14 at 11:19

Instead of importing android R class , import R class with your package name.
