WaveUp is by far one of the handiest tools you can add to your Android arsenal! I’ve used this app for over a year now, and I love it! It’s like playing Jedi mind tricks on your phone! You can turn your screen on and off, simply by a wave of your hand over the proximity sensor of your phone, which is really useful to me personally. ‘juanitobananas’ was kind enough to answer a few questions for me in an email interview, as I have been trying to get in touch with open source developers and learn about the story behind the apps.
A straight forward interface.
First of all, thank you, alaskalinuxuser! I’m glad you like WaveUp and
that you find it handy! 😉
As a huge open-source fan, I always try to use the open-source
counterparts of the apps I like. That is, if they are available. This
was not the case for ‘Gravity Screen On/Off’. This is where the
maybe-I-could-develop-such-an-app-myself idea started forming in my head.
Basically, the reason for me to create WaveUp was a combination of the
following: already being a programmer, my love for open-source software,
the non-existence of an open-source equivalent of an app I liked and a
will to contribute in some way to the open-source world, which had been
an itch I’d wanted to scratch for a long time.
Regarding the ‘jump into Android development’ part, I’d say WaveUp was
the perfect app for me to get started with something new, due to its
very simple nature. I was pretty certain I’d be able to develop
something like that relatively fast and in my free time.
straightforward. Although this was definitely not the case for Oreo.
Without getting into too many details, Oreo introduced a much more
restrictive background execution policy. WaveUp needs to constantly run
in the background to work properly. To be more accurate, it just needs
to listen for proximity sensor events. I had always wanted to avoid
adding a permanent notification, but Google made it impossible in Oreo.
I had to put in some work to make WaveUp compatible with Oreo, and I’m
quite sure I haven’t been able to solve all the problems that arose.
being very intense (programming-wise I mean). My story isn’t the one of
a ‘natural hacker’, hacking stuff since I was a kid. I actually just
learned a little bit of Java and (less) C at university. With these
modest skills I landed my first job, where I would not only program. The
more I programmed the more I liked it. Today it’s my job and one of my
released under an open-source license. Contributing to the open-source
world was just one of the main reasons for me to start playing around
with WaveUp. If I get a little deeper into this, I also believe in a
naïve and (scarcely) philosophical way that open-source makes the world
a slightly better place. I also enjoy believing that open-source is one
of the best expressions of freedom we have nowadays in our world.
The Germans use a word I love: ‘jein’. Jein is a combination of ‘ja’
(yes) and ‘nein’ (no). The answer to your question would be, jein. When
I decided to license it, I took a look at the most common open-source
licenses. I wasn’t sure if I wanted to license it under one of the more
restrictive licenses like GPL or one of the less restrictive (freer)
ones like MIT or Apache.
I really like the Free Software Foundation and see Richard Stallman as a
visionary, so I decided to go for GPL without thinking much further. I
like the idea of the derivative works being open-source too (although I
see it as a limitation of freedom). I might change it, but for now, I am
happy with GPL.
Good question! I know what you mean. The amount of frustration you have
to be able to bear as a programmer is pretty high.
I guess I *do* have a natural positive attitude towards things. That
helps. A lot. Throughout the years I have gained a lot of patience. This
is essential. But it has just become better after years. It is not
something I have consciously done to make my job (or hobby) better.
There definitely is a difference between me as a hobby programmer and as
a professional programmer. At home, I fight with stuff until it isn’t
fun anymore, and then look for something fun to do. My motivation at
home is to have fun with it and learn. At work I do fight a little
further. But not too much. If I hardly had fun at my job, I could really
not do it.
I get quite a lot of reviews in Google Play Store, but the way the
reviews in the Play Store are designed don’t really allow for a lot of
I receive a couple of emails a week, I’d say. I haven’t really counted.
WaveUp’s gitlab repo has had a total of 107 issues in its two and a half
I’d also count all the people who translate it as an interaction, and
that’s beautiful. WaveUp’s first translation (apart from the languages I
translated myself) was Japanese. That was a Merge Request in GitLab. I
was really happy to see that. Most of the translations are done by
people using transifex, which kindly hosts open-source projects for free.
Mostly I see it as complete. At least for me. Although I *am* currently
I am working on a new feature to avoid locking the screen if a certain
app is running in the foreground.
I get a new feature request once in a while. Some of these I implement
but most I try to politely deny. Not because I don’t think they’re good,
but because I prefer to keep the app really simple, which I think is one
of the good things about WaveUp.
I still work on WaveUp once in a while, but not as much as I did the
first (and maybe second) year. Well, or some months ago with the Oreo
compatibility issue I spoke about earlier.
There isn’t much here, maybe ‘Scrambled Exif’
(https://gitlab.com/juanitobananas/scrambled-exif) which is a simple
Android app to remove metadata from pictures before sharing them.
Right now I am also working on ‘Drowser’
(https://gitlab.com/juanitobananas/drowser). The motivation behind this
one was to learn some Kotlin and write a replacement app for Greenify.
For those who don’t know, Greenify is a great app written by oasisfeng
used to basically stop apps from running in the background, but
unfortunately proprietary. Although I’d trust the developer, I prefer
the code to be open. So in order to learn some Kotlin and kill some
rogue apps in the background I started creating Drowser.
You’re very welcome! Thank you too!
I’d say: Go ahead! Make mistakes. Be patient. Have fun!
Also, if you ask for help politely, you’ll probably get it.
