Thanks for the answer,
I have tried working with my code and looking at your widget's source.
Event though, I can't get it working. I do not use a service as you,
but my code looks like this:
package com.kaloersoftware.kaloertimerwidget;
import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.Context;
import android.content.Intent;
import android.widget.RemoteViews;
import android.widget.Toast;
public class KaloerTimer extends AppWidgetProvider {
@Override
public void onUpdate(Context context, AppWidgetManager
appWidgetManager,
int[] appWidgetIds) {
Intent i = new Intent(context, KaloerTimer.class);
PendingIntent pi = PendingIntent.getBroadcast(context,0, i,0);
RemoteViews rv = new RemoteViews(context.getPackageName(),
R.layout.main);
rv.setOnClickPendingIntent(R.id.startBtn, pi);
}
@Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
Toast.makeText(context, "It Works", Toast.LENGTH_SHORT).show();
}
}
Btw, is there any way to debug a widget? Nothing happens when I place
a breakpoint in the onUpdate() method.
