Android: Widgets not showing in app drawer ICS

Question

I have two widgets and neither of them will show up in the app drawer. What's weird is that if I remove one from the manifest it won't show up either but I can't see what I am doing wrong. From all the other questions I searched it looks right. The app is not being installed on the SD card.

Anyone have any ideas?

AndroidManifest.xml

<receiver
        android:name=".appwidgets.WidgetLarge"
        android:label="@string/Widget_large"
        android:icon="@drawable/icon" >
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
        </intent-filter>
        <intent-filter>
            <action android:name="com.groggs.action.CACHE_UPDATE_FINISHED" />
        </intent-filter>
        <intent-filter>
            <action android:name="WIDGET_UPDATE" />
            <data android:scheme="content" />
        </intent-filter>

        <meta-data
            android:name="android.appwidget.provider"
            android:resource="@xml/widget_large_info" />
    </receiver>

    <receiver
        android:name=".appwidgets.WidgetSmall"
        android:label="@string/Widget_small"
        android:icon="@drawable/icon" >
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
        </intent-filter>
        <intent-filter>
            <action android:name="com.groggs.action.CACHE_UPDATE_FINISHED" />
        </intent-filter>
        <intent-filter>
            <action android:name="WIDGET_UPDATE" />

            <data android:scheme="content" />
        </intent-filter>

        <meta-data
            android:name="android.appwidget.provider"
            android:resource="@xml/widget_small_info" />
    </receiver>

widget_large_info.xml

<?xml version="1.0" encoding="utf-8"?>

    android:initialLayout="@layout/widget_layout_large"
    android:configure="com.groggs.appwidgets.config.HubQuickViewWidgetConfig" >
</appwidget-provider>

widget_small_info.xml

<?xml version="1.0" encoding="utf-8"?>

Answer 1

Add "minHeight" and "minWidth" attributes to your appwidget-provider elements for each of your appwidgets and see if this does the trick for you.

If you check logcat when running it in the emulator, you should notice the launcher outputting a message about invalid dimensions and the name of your widget will be attached to this line.

I just had this issue and this is how I solved it (although I had one min and on max provided on accident). The logcat message said I had a dimension of (108, 0). This lead me into looking at all my dimensions since it was yelling at me for height being 0.

If your app is only an appwidget, with no activities besides a configuration one, you need a dummy main activity to make your appwidget appear in the drawer.
