Home Screen Widget step-by-step - create our AppWidget Provider by extending AppWidgetProvider.
It's part of the Home Screen Widgets step-by-step series.android.appwidget.AppWidgetProvider is a convenience class to aid in implementing an AppWidget provider. Everything you can do with AppWidgetProvider, you can do with a regular BroadcastReceiver. AppWidgetProvider merely parses the relevant fields out of the Intent that is received in onReceive(Context,Intent), and calls hook methods with the received extras.
Extend this class and override one or more of the onUpdate(Context, AppWidgetManager, int[]), onDeleted(Context, int[]), onEnabled(Context) or onDisabled(Context) methods to implement your own AppWidget functionality.
At this moment, just implement our dummy AppWidgetProvider class, WidgetProvider.java. We will include it in our AndroidManifest.xml later.
package com.example.androidhomewidget;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.Context;
import android.content.Intent;
public class WidgetProvider extends AppWidgetProvider {
@Override
public void onDeleted(Context context, int[] appWidgetIds) {
// TODO Auto-generated method stub
super.onDeleted(context, appWidgetIds);
}
@Override
public void onDisabled(Context context) {
// TODO Auto-generated method stub
super.onDisabled(context);
}
@Override
public void onEnabled(Context context) {
// TODO Auto-generated method stub
super.onEnabled(context);
}
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
super.onReceive(context, intent);
}
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
// TODO Auto-generated method stub
super.onUpdate(context, appWidgetManager, appWidgetIds);
}
}
