<p>I have just made very simple widget, have installed it on emulator and it works. But if i try to install on phone I will have my application crashed. Check this code please:</p>

<p>Layout for widget:</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:background="@android:color/white"
    android:layout_gravity="center"&gt;

    &lt;TextView android:id="@+id/widget_textview"
        android:text="Hello Widget"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:layout_gravity="center"
        android:textColor="@android:color/black"/&gt;
&lt;/LinearLayout&gt; 
</code></pre>

<p>AppWidget provider(xml folder):</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"

        android:label="@string/app_name" &gt;

        &lt;receiver android:name=".HelloWigdet" android:label="@string/app_name"&gt;
            &lt;intent-filter&gt;
                &lt;action android:name="android.appwidget.action.APPWIDGET_UPDATE" /&gt;
            &lt;/intent-filter&gt;
            &lt;meta-data android:name="android.appwidget.provider"
                android:resource="@xml/widget_provider_info" /&gt;
