I've read several questions about this on stackoverflow, and none of the answers are solving my problem.
I'm trying to add a home screen widget to my app, and my widget does not appear in Android's widget list.
I've tried rebooting the device, reinstalling the application, changing parameters in the configuration file, ensuring app is not installed on SD card. Nothing is working.
Here is the code I currently have:
Inside AndroidManifest.xml's application tag:
<receiver
android:name=".GulpWidgetProvider"
android:icon="@mipmap/ic_launcher"
android:label="Gulp">
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
<meta-data
android:name="android.appwidget.provider"
android:resource="@xml/gulp_widget_info" />
</receiver>
Inside /res/xml/gulp_widget_info.xml:
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"
android:initialLayout="@layout/layout_widget"
android:minHeight="150dip"
android:minWidth="400dip"
android:updatePeriodMillis="86400000"
android:widgetCategory="home_screen"
android:resizeMode="none"
android:minResizeHeight="150dip"/>
Inside /res/layout/layout_widget.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Inside /java/info/andrewdahm/gulp/GulpWidgetProvider.java:
public class GulpWidgetProvider extends AppWidgetProvider {
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
final int N = appWidgetIds.length;
// Perform this loop procedure for each App Widget that belongs to this provider
for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i];
// Create an Intent to launch ExampleActivity
Intent intent = new Intent(context, Main.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
// Get the layout for the App Widget and attach an on-click listener
// to the button
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.layout_widget);
views.setOnClickPendingIntent(R.id.widget_add, pendingIntent);
// Tell the AppWidgetManager to perform an update on the current app widget
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
}
Any ideas why my widget isn't appearing on the list of widgets?
