It took me more than a hour to find the cause of it. It turns out that I didn’t cancel my Timer.scheduleAtFixedRate() TimerTask that updated a dynamic part of my UI.

If you are struggling with memoryleaks as well, make sure you install the eclipse addon : “Memory Analyzer”. If you have that one installed, you can use DDMS in Eclipse to dump a hprof file, which automatically get’s opened and you can then get lots of usefull info on your leaks. Use the “dominator tree” to show the largest items in memory, and right click on them and select “Path to GC roots => With all references” This shows what’s keeping them in memory.

I couldn’t find my leaks at first, because the Path to GC roots, didn’t include any obvious Context leaks or so (the normal stuff that causes memory leaks: static Context/Activity values).  However, after an hour I realized that the “TimerTask” I first dismissed as some Android internal stuff, actually was the cause of my issues.

I then made sure to “cancel()” my timertask in my activity’s “onDestroy()” method, and things turned to normal!

However, I wanted to try a better soundcard for it, so the audio quality would be even better. Therefor I bought a Xonar DSX.

Unfortunately this soundcard wouldn’t install when I ran the windows 8 drivers. It gives a message that the OS is not supported. Strange, since it’s the same as Windows 8. Probably a case of a little too strict checking.

Anyway, solution to install Xonar windows 8 drivers on windows 2012:

1. Download Windows 8 driver for your Xonar card.
2. Extract the zip file.
3. Open the win8 dir (do not run setup in the dir above it)
4. Edit the file CmSetx.dll with notepad. (it’s not a binary file, just a txt file)
5. Change the line with  SupportOS to “SupportOS=donotcare”
6. Save and run the setup in the same folder.
7. It will now install and work ok!

This will probably also work with DGX, DG, DS, and other Asus Xonar cards.

Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(“http://www.amazon.com/gp/mas/dl/android?p=” + packageName));

However, the docs also state that you can link to all your apps by adding a parameter to the url.

i.setData(Uri.parse(“http://www.amazon.com/gp/mas/dl/android?p=” + packageName+”&showAll=1“));

This used to work, and I used it to link my Amazon users to all my apps.

However, I was debugging my app and today I suddenly found that this all apps linking doesn’t work anymore on my Kindle Fire. I also downloaded the latest amazon appstore to my emulator, and it also didn’t work there. So, somehow a update of the store app apparently has a regression in it. I doubt it’s intentional.

Fretter 1.4 for iOS features a new reverse finder where you can select the notes on a fretboard, instead of using a pickerview.

Will be released in a few weeks.

update

The 1.9 version with this new reverse finder is live!

It fixes a crash in the instrument selection view related to custom tunings.

Update

Fretter 1.3.3 has been approved and is available now.

It now shows all my apps for Android with screenshots and links to the various markets.

Update
1.3.2 has been approved by Apple and is now available on the App Store.

New features include:

• Custom instruments and tunings
• New design
• Favorite Chords

Now you can create your own instruments with variable amount of strings, and add several custom tunings to them. Because you can now also select the octave of the stringnote, playback is enabled when using custom tunings.

The design matches Keychord, and we hope you like it.

You can now easily select chords you like, and they are accessible through the favorites menu option.

I already heard about Linode and already had a 512MB instance for running the addonsdetector definitions download site.  However, I now needed to setup mail servers and all the other websites I had.

I must say, that Linode works great, but above all, it’s their great library with tutorials on every subject you need, that makes Linode great! I now have succesfully setup a quite secure setup, with mail and websites.

I learned a lot during this process, and if you are a bit of a linux guy, really consider it for your hosting!!
