Widget is not loaded on AVD

I'm trying to create a widget for Android. It contains such files:

res/xml/widgetinfo.xml:

<?xml version="1.0" encoding="UTF-8"?>
<appwidget-provider
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:minWidth="146dip"
  android:minHeight="146dip"
  android:updatePeriodMillis="3600000"
  android:initialLayout="@layout/main" />

res/layout/main.xml:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
    <LinearLayout >
        <TextView android:text="My widget" />
    </LinearLayout>
</FrameLayout>

AndroidManifest.xml:

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

    <uses-sdk android:minSdkVersion="10" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name">
        <receiver android:name="WidgetProvider">
            <intent-filter>
                <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
            </intent-filter>
            <meta-data android:name="android.appwidget.provider"
                android:resource="@xml/widgetinfo" />
        </receiver>
    </application>
</manifest>

src/com.test.WidgetProvider:

package com.test;

import android.appwidget.AppWidgetProvider;

public class WidgetProvider extends AppWidgetProvider {
}

But when I run it in AVD and trying to add my widget it displays the message "Problem loading widget". LogCat shows nothing in verbose mode. So, what is wrong?

  1. You need to implement onUpdate() in your AppWidgetProvider.

  2. Your layout does not work. You could tell this by trying your layout in, say, an activity. You are missing android:layout_width and android:layout_height on the LinearLayout and the TextView. Also, it is unclear what your FrameLayout is doing for you.
