Array error

For the Blog Reader app I just created an array and I get this message in the MainListActivity.java " array cannot be resolved or is not a field ". In the strings.xml I get an error saying " Attribute name "Android" associated with an element type "item" must be followed by the ' = ' character "

error on line 19

MainListActivity.java

package net.kneisel.blogreader;

import android.app.ListActivity; import android.content.res.Resources; import android.os.Bundle; import android.view.Menu; import android.widget.ArrayAdapter;

public class MainListActivity extends ListActivity {

protected String[] mAndroidNames;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main_list);

    Resources resources = getResources();
*19*    mAndroidNames = resources.getStringArray(R.array.android_names);

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mAndroidNames);
    setListAdapter(adapter);

    //Toast.makeText(this, getString(R.string.no_items), Toast.LENGTH_LONG).show();
}

@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_list, menu);
    return true;
}

}

Can you post your code from your strings.xml file? Check to make sure your syntax is correct.

Does each item look like this inside the string-array tag?

<item>value</item>

looks like you forgot the closing angle bracket for your item tags

still get an error on line 2: Multiple annotations found at this line: - Attribute name "Android" associated with an element type "item" must be followed by the ' = ' character.

<string-array name ="android_names">
    <item>Android beta</item>
    <item>Android 1.0 </item>
    <item>Android 1.1</item>
    <item>Cupcake</item>
    <item>Donut</item>
    <item>Eclair </item>
    <item>Froyo</item>
    <item>Gingerbread</item>
    <item>Honeycomb </item>
    <item>Ice Cream Sandwhich</item>
    <item>Jelly Bean</item>
    </string-array>

The code you posted in the above comment is correct so the problem is probably somewhere else. Can you post the code for your entire strings.xml file?
