Cannot send pending intent from widget, SendIntentException

I want to send a broadcast from my widget with this code:

for (int i = 0; i < N; i++) {
   int appWidgetId = appWidgetIds[i];
   RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
   Intent x = new Intent();
   if (isActive == true) {
      vie开发者_高级运维ws.setImageViewResource(R.id.w_image, R.drawable.w_bild);
      x.setAction("de.bulling.smstalk.DISABLE");
   } else {
      views.setImageViewResource(R.id.w_image, R.drawable.w_bild_off);
      x.setAction("de.bulling.smstalk.ENABLE");
   }
   PendingIntent z = PendingIntent.getBroadcast(context, 0, x, PendingIntent.FLAG_ONE_SHOT);
   views.setOnClickPendingIntent(R.id.w_image, z);
   appWidgetManager.updateAppWidget(appWidgetId, views);
}

However, I get this error:

E/RemoteViews(18176): Cannot send pending intent:

What's the reason for this? Do you have any idea? Thanks, Marc

/edit: I found the answer: It has to be Intent x = new Intent(context, WidgetClass.class);

I got this error to:

RemoteViews: Cannot send pending intent:  
RemoteViews: android.content.IntentSender$SendIntentException 
RemoteViews: at android.app.ContextImpl.startIntentSender()

The solution was to set a unique requestCode for each (sending) PendingIntent, and for this I used the provided appWidgetId instead of just using a 0 each time.

getBroadCast()

pendingActionIntent=PendingIntent.getBroadcast(this, widgetId, intentAction, pendingFlag );

getActivity()

pendingActionIntent=PendingIntent.getActivity(this, widgetId, intentAction, pendingFlag);

For some unknown reason it says it "currently not used" in the documentation?

requestCode Private request code for the sender (currently not used).

but it works;)

I think the request codes are used to match updates and replacements via PendingIntent.FLAG_CANCEL_CURRENT and PendingIntent.FLAG_UPDATE_CURRENT.
