A simple Android widget that launches activity

Hi, I have never worked with widgets before, but what I want to do is create a very simple widget in which I want to make a 1 to 1 widget that has only an icon, just an image set as background text will not just a small icon, and when the icon is clicked, I want to open the action. Basically, I want to make a second icon, like in an application box, in the form of widgets that opens up another action, not the main one. Any help is appreciated.

My provider turned out to be the same after a lot of research and games.

public class WidgetProvider extends AppWidgetProvider {
    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        final int N = appWidgetIds.length;

        for (int i=0; i<N; i++) {
            int appWidgetId = appWidgetIds[i];

            Intent intent = new Intent(context, ClassToLaunchHere.class);
            PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

            RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
            views.setOnClickPendingIntent(R.id.widget, pendingIntent);

            appWidgetManager.updateAppWidget(appWidgetId, views);
        }
    }
}

Declare a variable

public static String YOUR_AWESOME_ACTION = "YourAwesomeAction";

then add onUpdate and onReceive

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
                     int[] appWidgetIds) {
    ComponentName thisWidget = new ComponentName(context, DigitalClock.class);

    RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.digital_clock);

    for (int widgetId : appWidgetManager.getAppWidgetIds(thisWidget)) {
        remoteViews.setOnClickPendingIntent(R.id.imageView, getPendingSelfIntent(context, YOUR_AWESOME_ACTION));
        appWidgetManager.updateAppWidget(thisWidget, remoteViews);
    }
}

@Override
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    super.onReceive(context, intent);

    if (YOUR_AWESOME_ACTION.equals(intent.getAction())) {

        AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);

        RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.digital_clock);
        ComponentName watchWidget = new ComponentName(context, DigitalClock.class);

        appWidgetManager.updateAppWidget(watchWidget, remoteViews);

        Intent ntent = new Intent(context, MainActivity.class);
        ntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(ntent);

        //Toast.makeText(context, YOUR_AWESOME_ACTION, Toast.LENGTH_SHORT).show();
    }
}

protected PendingIntent getPendingSelfIntent(Context context, String action) {
    Intent intent = new Intent(context, getClass());
    intent.setAction(action);
    return PendingIntent.getBroadcast(context, 0, intent, 0);
}

and add activity to the manifest

<activity android:name=".MainActivity">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

hope this helps
