Question

I am new in android development. I am using Eclipse Helios and AVD 15. I am trying with a tiny program Sliding Drawer. Whenever I want to run it, compiler shows no error but in Emulator shows “Unfortunately has stopped. I uninstall it then run it for several times, Clean project, eliminate each warning still it coming. When I run it on debug mode , the console shows:-

I am sending my code:

.java file

package sliding.drawer;

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

public class SlidingdrawerActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
}
}

main.xml file

<?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="fill_parent"    >
     <SlidingDrawer
          android:id="@+id/drawer"
          android:layout_width="320dip"
          android:layout_height="440dip"
          android:orientation="vertical"
          android:handle="@+id/handle"
          android:content="@+id/content">
    <ImageView
          android:id="@+id/handle"
          android:layout_width="48dip"
          android:layout_height="48dip"
          android:contentDescription="@string/s"
          android:src="@drawable/ic_launcher" />
    <AnalogClock
          android:background="#D0A0A0"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent" />
    </SlidingDrawer>

  <TextView
         android:layout_width="fill_parent"
         android:layout_height="wrap_content"
         android:text="@string/hello" />
</RelativeLayout>

Then a window comes with thread status.

I think the problem is you forgot the id attribute on your AnalogClock:

<AnalogClock
    android:id="@+id/content"
    android:background="#D0A0A0"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" />
