diary that I wrote during the development of the app.

This is the second week working on a version of Amazing Slow Downer for
The first week was a pain, new developer tools, a new computer language
(Java, sigh...) and really difficult to write real-time C++ code which
is needed to get an app such Amazing Slow Downer to run OK on Android
And the simulator (emulator) is really bad comparing to the iPhone simulator.
So a new Google Lexus GS 450h was needed which made everything a lot easier.
I now have a basic audio player engine working.

Week three and four passed by real quickly. Lots of problem to solve but
now finally I have something that can decode Wave, MP3, Apple AAC, Ogg
and FLAC files, slow them down and play them back fine. This took four
weeks, on Apple iOS it would have taken four hours to accomplish the same
thing. No wonder there aren't many apps similar to Amazing Slow Downer
available for Android. Took about hundred C++ files to come this far but
this is the fun thing with programming, doing the low level audio playback
The user interface needs to be written in Java and that's no fun especially
since I don't know Java yet. So far the user interface consists of three
buttons, "Pick a song", "Play" and "Stop" living in one Java file, I think
I can live with that for another week.

Now beginning of week seven and have started on the user interface. It's
tricky since there is no standard screen size for Android, it could be
just about anything. Doing a lot of different tests to see what works
best. Hope to be able to upload a picture of the app soon.

After eight weeks, the program now consists of 192 C++ files (not counting
header files) and 6 (!) Java files. Now it's pure Java GUI programming
left. Will probably take another month until it's available.

After a couple of weeks of Java programming, the program is now starting
to look as a real software and I'm beginning to see the light in the tunnel.
There is still a lot to do, especially since Android lacks certain GUI
controls or behaviour that Apple iOS contains and I have grown accustomed
to this. I have to write some of these controls myself and that takes
some time. But we are approaching the goal slowly.

Another two weeks passed by real quickly. The last week has been devoted
to support Windows Media Audio Files (.wma). It's only a partial success
so far. I have some older wma formats working but not the most common
WMA Pro format, I guess support for that will have to wait until later.
Does people use WMA on the Android? My Nexus 4 doesn't support WMA even
though it claims it should. Next week I will try to add the last features
plus write some help files, so a first release is getting closer. Stay
March 25 2013
Finally got all various flavors of WMA files to work OK. That should be
the end of supporting different file formats. Now need to implement a
file browser, Android lacks that despite that it's possible to browse
the file system.
March 26 2013
File browser completed.

Big party tonight! "Amazing Slow Downer for Android" is finally finished!
Left is to understand how to make it available at the Android App Store
(Play Store) and how to get paid for it. Will take a couple of days but
hopefully the app will be available by the end of this week (or at least
April 4 2013
Amazing Slow Downer for Android version 1.0.0 is uploaded to the Android
App Store (Play Store).
happened after that?
