Looking through the source code, it looks like there is no default DataSetObserver. Worse is the fact that the DataSetObserver interface is private to the Android Compatibility Library so you can’t even supply your own ! Luckily, a workaround can be found as follows:

Create a new class called PagerAdapterCompat with the package name android.support.v4.view

package android.support.v4.view;

public abstract class FragmentPagerAdapterCompat extends FragmentPagerAdapter {
    public FragmentPagerAdapterCompat(FragmentManager fm) { super(fm); }

    public interface DataSetObserver extends PagerAdapter.DataSetObserver {}

    public static void setDataSetObserver(PagerAdapter adapter, DataSetObserver observer) {
        adapter.setDataSetObserver(observer);
    }
}

Don’t forget to hit Ctrl+Shift+O in eclipse to get those imports added

After this, you can simply create your own DataSetObserver (I made mine pretty basic by calling destroyItem() on each page) and set it with FragmentPagerAdapterCompat.setDataSetObserver(your_adapter, your_observer);

All credit goes to this guy for reporting the bug and providing a quick and easy solution: http://code.google.com/p/android/issues/detail?id=19110 (although his is more general for the PagerAdapter)

Please head on over there to star the bug so that it get’s more attention!

The other aspect that I was interested in is the fact that Windows Phone 7 development centers around C#, and I’ve been looking for every excuse to try out C#. An improvement to C? Something better than Java? Why not?

So, after signing up to Microsoft’s AppHub, I decided to try my hand at the Mango update. It only took a day to get an invite for the Mango update. And only a few hours to install it onto my phone:

My opinion so far: Awesome

Everything right away is way smoother. There’s a lot of integration with Facebook, Google, and of course Live while there’s still enough options to ensure you can disable one or the other. It’s the kind of integration that’s functional without being annoying.. I’m surprised anyone was able to pull it off better than Android.

Now with that, I still feel there’s quite a bit to go. There’s a couple of annoyances to Windows Phone 7 that just has me holding back. For one.. why do I have to tap the status bar to see my phone’s reception? I mean the number one most important piece of information of a cellphone is your cell reception. Or am I just crazy? There’s a few others.. but I’ll leave it at that.

Get KBudget 0.40 on the market today! And let me know what you think of the new User Interface!

Go check it out now to find the charts, new view mode, and some minor UI changes.

Next version will contain more chart options

So basically, I could use some users who would be willing to test out some less than perfect versions every once and awhile. If you’re interested, contact me using the contact form (here) or send an email to andrew @ this domain name.

Sorry about that..

What’s next for KBudget? Here’s a few of the things I have planned:

• UI Overhaul (working on some concepts but if any artists out there want to help, I’m sure I could use it)
• add weekly/bi-weekly budgeting support
• add some graphs (this one will be tougher given that the app is free so I’ll have to write this from scratch)
• a super secret feature that I’m sure you’ll all love

If you have an idea you’d like to suggest for KBudget, send me an email or use the contact page on this site.

In other news, KBudget 0.22 will be added to the marketplace soon. This is just a minor update which adds Chinese Locale Support (thanks to goapk.com).

Hopefully there aren’t any other issues with this release. But let me know in the comments or through the contact page if you run into any problems!

This update brings some new features such as password protection, basic export/import functionality, auto completion box for transactions, and more!

Hopefully there won’t be any unexpected bugs, but let me know if you run into any!

It’s been running great for the past 2 months but suddenly I noticed it was acting up. I got several errors like this:

May 6 05:53:46 kwasik postfix/smtp[20753]: certificate verification failed for smtp.gmail.com[74.125.113.109]:587:
untrusted issuer /C=US/O=Equifax/OU=Equifax Secure Certificate Authority


May 6 05:53:46 kwasik postfix/smtp[20753]: 25CF63C05A: to=, relay=smtp.gmail.com[74.125.113.109]:587, delay=2509, delays=2509/0.16/0.26/0, dsn=4.7.5, status=deferred (Server certificate not trusted)


At first, I thought something went wrong with my SSL certificates, so I tried re-doing those. No luck. Several hours later, I stumbled upon this:

http://www.google.com/support/forum/p/gmail/thread?tid=7e4a679f5917149e&hl=en

Seems Google decided to change their Certificate Authority.. instead of using Thawte, they’re now using Equifax (no wonder Equifax kept popping up in my log).

Anyways the simple fix (run as root):

cat /etc/ssl/certs/Equifax_Secure_CA.pem >> /etc/postfix/cacert.pem

Mind you, the above applies to Debian 5.0, but it should at least help you on your way to fixing the problem.
