Question

In my project I have got some classes and some layouts. I add a new package to my project and I in new classes from this new package there is a problem: e.g. when I writing “setContentView(R.layout.author_xml);” I have got red underline and comunicate: “R cannot be resolved to a variable”. In adnroid manifest when I use activity from new package I add:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.tom"
android:versionCode="1"
android:versionName="1.0" >

<activity
    android:name=".menu.NewGameActivity"><!--I add .menu-->
</activity>

Generally in classes from new package I can’t see a layout. Maybe I should add something in layout, e.g:
android:package=”com.tom.menu” -> but it doesn’t work.
What can I do in this situation? Thank you in advance.

If you have a class in a subpackage, e.g. com.tom.mypackage, you have to import your R from base package mentioned in manifest. Just put import statement into you classes which are in subpackages and which don’t see the R:

package com.tom.menu; // class in subpackage

import com.tom.R;  // This will get you your R from base package

import android.app.Activity;

public class NewGameActivity extends Activity {

// use R here like you are used to
