How to change widget view in background service - android-widget

Question

I have created widget. I am trying to update the widget in background each 5 seconds (For testing purpose 5 second). But it is not getting update.Is any mistake on my code.
Provider class
package com.widget.widgetapplication;
import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.RemoteViews;
import android.widget.Toast;
import java.util.Random;
public class MyWidget extends AppWidgetProvider {
private int randomNumber = 0;
#Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
Toast.makeText(context, "Receive", Toast.LENGTH_SHORT).show();
}
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
Toast.makeText(context, "Update", Toast.LENGTH_SHORT).show();
// Get all ids
ComponentName thisWidget = new ComponentName(context,
MyWidget.class);
int[] allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget);
for (int widgetId : allWidgetIds) {
// create some random data
randomNumber = new Random().nextInt(100);
RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
R.layout.widget_layout);
Log.w("WidgetExample", String.valueOf(randomNumber));
// Set the text
remoteViews.setTextViewText(R.id.time, String.valueOf(randomNumber));
appWidgetManager.notifyAppWidgetViewDataChanged(widgetId, R.id.time);
// Register an onClickListener
Intent intent = new Intent(context, MyWidget.class);
intent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context,
0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.watch, pendingIntent);
appWidgetManager.updateAppWidget(widgetId, remoteViews);
}
}
}

Answer 1

YES. you are doing it wrong.
the minimum available value for updatePeriodMillis is 30min (1800000 millis).
official document :
Note: Updates requested with updatePeriodMillis will not be delivered more than once every 30 minutes.
