As of now my Google Developer page is also active. It can be called just a first draft anyway 🙂
You can reach it using the link below:
You can access all programs in my personal developer account from here. I’ll try to write more Android apps with Qt and OpenCV as soon as I get some more free time.
You can access Image Transformer website using this link.
From now on I’ll post all updates and announcements there.
You can still use CONTACT ME page on my personal website here to send your source-code requests.
I start Qt for Android projects all the time and setting up all the required folders and including libraries can take some time, assuming that I don’t make any mistakes during the initialization of the project. Previously I had posted this about how to add OpenCV libraries to your Qt for Android project but it proved to be not enough and I also receive questions about how to create a correct project with OpenCV all the time.

If you want to upload an Android application into your Google Play Developer account then you have to sign your apps. Pictures below explain how you can do this in Qt.

Whether you want to use GPS or Compass, Camera or the Internet, you will need to add permissions to your Qt app for Android because Android API uses a permission system for security reasons. It actually has other benefits such as helping with monitoring and app statistics and so on but I’m not going to discus that in this post.
If you need to add permissions to your Qt Android app then follow these steps.

When you create an Android app in Qt, the icon of your app remains the default set by Qt, it’s this one:
Usually you want to change it for a more meaningful icon. Follow the steps bellow to be able to change this icon in Qt.

If you are a fan of Qt and don’t want to change to another IDE for developing Android apps then this post is for you.
Follow the steps below to have Qt for Android installed in your computer.

UPDATE: This application is updated. Please read this post for more information.
My new application is a tool for for performing Fourier transformation on images. You can then apply masks to the Fourier representation of image and revert back (perform Inverse Fourier Transform) to see how the image gets affected.
For more information about Fourier Transform you can check out this link.
It is built using OpenCV and Qt and it is programmed completely in C++. I hope it would be useful for Image Processing and Machine Vision enthusiasts, researchers and students. It also contains some useful tips and tricks for programming Android applications using Qt and OpenCV such as:
- How to open Android image gallery in Qt (Default interface)
- How to capture images using default Android camera interface
- How to crop images displayed on a QLabel
Source code (any part of it actually 🙂 ) is available upon request. Please send your requests using the Contact Me page.
Please consider supporting this application by giving a decent rating in Google Play.
For an example of Fourier transform using OpenCV please check out this link.
You can also see this link for more information about Fourier transform.
You can download this application from Google Play using the link below:
I use this method for having simple access to a parent class’ functions in Java. Please note that this is not a recommended method but in case of programs with not much lines of code it becomes really helpful and easy to implement.

Another note to myself which I hope will be useful for others searching it.
Add the following lines to your PRO file in Qt, or create a PRI file using the following and include that in your PRO file.
