Question

Hi every body i’m currently trying to solve a strange problem.
I reduced as mush as i could my app to show you clearly the problem.

I can launch my app with the main layout just like this:

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

With this main.xml

<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/main"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
</ListView>

Nothing really new about that BUT if i add a new layout named list.xml within the layout directory my app crashes… i don’t understand. Here is the log (Once i add the new xml the program doesn’t find the main.xml ressource)

Thanks for your help guys 😀

EDIT

This is my list.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="100dip" >
    <ImageView 
        android:id="@+list/thumb"
        android:layout_width="60dip"
        android:layout_height="60dip"
        android:layout_centerVertical="true"
        android:layout_alignParentLeft="true"
        />
    <TextView
        android:id="@+list/text"
        android:layout_toRightOf="@+list/thumb"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="18dip"
        android:layout_marginLeft="10dip"
        android:layout_centerVertical="true"
        android:singleLine="true"
        android:ellipsize="end"
        android:textStyle="bold" 
        />
</RelativeLayout>

And my manifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.infotel"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="15" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".AndroidReaderActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

There is no problem everything is fine , please once clean your project then run again,because your resources java file not properly build.

or

check once your project package name should be similar in manifest file.
