Android project is not loading, it generate unusual error

Question

In my android application, I had create a simple application, in eclipse by file>project>Androiapp I had put down simple activity, but the application gives error.

Layout File

<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"
    tools:context=".MainActivity" >

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

</RelativeLayout>

Code file

package com.example.testapp;

import android.R;
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.activity_main, menu);
        return true;
    }

}

As I can see there is no error in this code, but in eclipse it still generate error at setContentView(R.layout.activity_main); and getMenuInflater().inflate(R.menu.activity_main, menu);.

I think resource file is not loading

Note that I had not made any changes in auto generated code.

Same thought, I think your resource file is not loading... – Feb 24 '13 at 06:33 — , Feb 24 '13 at 06:33

Remove this line.

import android.R;

and Clean the project and then build it.

Could you remove this :

import android.R;

This would import the default resources bundle but you would want to import your local resources bundle. Since you are loading the activity you wouldnt need the local resources to be imported.

You could refer to any of these :

Android Eclipse Error "Android Packaging Problem"

Android Packaging Problem: resources.ap_ does not exist

Wild guess here: if you have an error in another XML file, then maybe this could block the creation of the auto-generated R file. Look under the gen folder and verify that the R.java file is there and well formed.
