building android 64 bit



  • Hi, i am still working on porting my app to api 26 per the new requirements for android 8, now i read that in 2019 apps have to be 64 bit. I use QT 5.10.1 and have android gcc for 64 bit in my kits. Is this enough to provide 64 bit android apps? Thank you.

    Hi and welcome to devnet forum

    No you have to ensure that everything is supported within your tool chain.

    In Qt creator you should go to "Tools"->"Options"->"Kits" and check under the different tabs.

    For example these are the different versions I have installed
    0_1547726913595_73f08376-47ef-42d9-a13f-159412d737ab-image.png

    By clicking on more details you can find the different tools involved, like:
    0_1547726994057_c52e52d9-14da-4bb5-a177-980bd7a7584e-image.png

    Similar you can sheck for the complete kit and also compiler and debuggers and stuff. If there special signs this is indicating a real problem or sometimes a warning to make you aware.

    The Version Qt 5.12.0 for arm is the pre-compiled version supplied through online installer. This is not 64 bit.

    When you require a different compiler such as 64 bit you would need to do a full configure and and build of the Qt libs on your own.



  • @koahnig So there's config and rebuild needed. Thank you very much for the helpful reply.
