Building QT 6.3.0 for Android on Windows with C++20

Dramatically annoying crash at std::thread and std::mutex destructors on Android

Posted by | Android, QT |

It is a long story that started here about 2 years ago. My first understanding was that it is a QT bug that was not fixed within this 2 years, of course (as a rule or usually), but a couple weeks ago I noticed that a similar crash happens on Samsung Galaxy devices:

An attempt to build static QT for Android

Posted by | Android, QT |

qtbase\cmake\QtPlatformAndroid.cmake contains this:

# Ensure we are using the shared version of libc++
if(NOT ANDROID_STL STREQUAL c++_shared)
    message(FATAL_ERROR "The Qt libraries on Android only supports the shared library configuration of stl. Please use -DANDROID_STL=\"c++_shared\" as configuration argument.")
endif()

and looks like -static-runtime works only for Windows.

I added -c++std c++20 -static -no-openssl to the configuration and removed -separate-debug-info:

Reducing the size of QT Android libraries

Tried to reduce the size of the QT Android libs by separating debug info with -separate-debug-info option and skipping the modules I do not use:

Building QT 6.2 for Windows with MSVC2019

Posted by | Android, QT, Windows |

I cloned QT repository:

git clone --recursive https://code.qt.io/qt/qt5.git --branch v6.2.0
cd qt5

Looks like the command below is not required:

./init-repository --module-subset=all

because it prints:

Will not reinitialize already initialized repository (use -f to force)!

QtPurchasing uses deprecated AIDL billing library

Posted by | Android, QT |

Looks like QtPurchasing uses deprecated AIDL billing library and people say that it crashes on some devices. See https://developer.android.com/google/play/billing/deprecation-faq for more information. Probably they are going to update it in 5.15.7 and move it into examples in QT 6, so it is not clear exactly what will happen with it, we probably better wait QT 5.15.7 to be released.

Built my QT app for Android with API level 30 (Android 11)

Posted by | Android, QT |

New Android App Bundle and target API level requirements in 2021:

Starting August 2021, new apps will be required to target API level 30 (Android 11) and use the Android App Bundle publishing format. Starting November 2021, all app updates will be required to target API level 30 (Android 11). Apps with a download size of more than 150 MB are now supported by Play Asset Delivery and Play Feature Delivery.

I updated the manifest manually as follows:

<?xml version="1.0"?>
<manifest package="net.geographx.LinesGame" xmlns:android="http://schemas.android.com/apk/res/android" android:versionName="2.5.30" android:versionCode="161" android:installLocation="auto">
    <uses-sdk android:minSdkVersion="21" android:targetSdkVersion="30"/>
