Configuring QT Creator with QT 6.6.2
I built QT 6.6.2, installed QT Creator and updated "%SystemDrive%\Documents and Settings\%USERNAME%\Application Data\QtProject\qtcreator\android\sdk_definitions.json" file as follows:
...
"specific_qt_versions": [
{
"versions": ["default"],
"sdk_essential_packages": ["build-tools;34.0.0", "ndk;26.2.11394342"]
},
{
"versions": ["6.4"],
"sdk_essential_packages": ["build-tools;31.0.0", "ndk;23.1.7779620"]
},
{
"versions": ["6.3", "6.2", "5.15.[9-20]"],
"sdk_essential_packages": ["build-tools;31.0.0", "ndk;22.1.7171670"]
},
{
"versions": ["5.15.[0-8]", "5.14.[0-2]", "5.13.2", "6.0", "6.1"],
"sdk_essential_packages": ["build-tools;31.0.0", "ndk;21.3.6528147"]
},
{
"versions": ["5.12.[0-5]", "5.13.[0-1]"],

Building QT 6.6.2 for Windows and Android
I installed MS Visual Studio, Android Studio and the following tools:
cmake-3.24.2-windows-x86_64
nasm-2.15.05
ninja-win
Python35
Strawberry
VulkanSDK
x86_64-12.2.0-release-win32-seh-rt_v10-rev0
and built QT for Windows with the following commands:

I’ll never use NEOXA wallet anymore
First when I recovered the wallet from the passphrase it displayed me a zero balance, I did a quick google search and fixed this by leaving password field empty, but after that I got “Transaction too large” message while trying to send some NEOXA amount to an exchange:
I was able to send 10 000 NEOXA, but not 20 000. What is the difference?
(more…)Using GDPR with 3-rd party Advertising SDKs
It is clear enough from Google docs how to show consent form in an Android app with Google Mobile Ads SDK:
First I call requestConsentInfoUpdate and then I call loadAndShowConsentFormIfRequired that shows the consent form if required.
I did not test this code, but as far as I can guess, Google Mobile Ads SDK checks if the user belongs to the region GDPR applies to, shows its own consent form and internally saves a flag indicating if the user agreed (pressed some Allow button in consent form).
(more…)Unification of Win32 and UWP
Looks like QT6 does not support UWP:
During this year’s Microsoft Build conference Microsoft announced the
unification of Win32 and UWP for their IoT offering. In general, it
looks like Microsoft is stepping away from their strict stance about the
usage of UWP technology and the Windows Store. Getting a classic Windows
application into the Windows Store is much easier nowadays and will be
even simpler in the future. Microsoft’s new direction in their IoT
offering will bring more “classic Windows development” into the IoT
world and there will be no need for a dedicated UWP port.
