Qt for Android

[Domel07]

Many thanks for your reply. Yes I did follow this link as well :) However, it has issues like e.g. "android" command being obsolete or "sdkmanager" plain not working.

At the end of my struggle I found that the only missing component of the puzzle on Windows was using (old) Java 8 instead of the latest 11.

However this only worked on Windows. Still can not come to terms on Linux. Followed all instructions to no avail. Compiled Qt no problem, Qt Designer complains with the mentioned red cross and does not automatically create kits. Have anyone here succeeded on Linux?

Use OpenJDK 8, Qt 5.12.1, newest SDK and NDK. For me it works.

@Domel07 I only ever had problems when I has android studio also installed on my system, or when I had more than 1 valid java installation.

Since I switched to command line tools only and stick with one jdk(working mind you) I haven't had any problems with Qt for Android

Thank you guys for all the replies. Can you please post your configuration command? Here is mine:

./configure -xplatform android-clang --disable-rpath -nomake tests -nomake examples -android-ndk /home/dominik/Android/Sdk/ndk-bundle/ -android-sdk /home/dominik/Android/Sdk -android-ndk-host linux-x86_64 -android-toolchain-version 4.9 -skip qttranslations -skip qtserialport -no-warnings-are-errors

Using At 5.12.1 and the latest sdk/ndk, open jdk 8.

Thanks!

@Domel07 Same problem under MacOS. It's very frustrating!
I need to develop an application for Android, communicating by Bluetooth with a measuring device (serial link emulation) and I'm stuck.
Help would be good.

Just confused or curious, I don't know. Are you building Qt yourself?

Is there something preventing you to develop on let's say a Linux host and connect your Android device and deploy to and run your Qt application on it?

[Domel07]

@Pablo-J.-Rogina yes, building Qt from sources. Because I could not find a Ubuntu prebuilt version. Is there a prebuilt version of the latest Qt for Ubuntu? I could not locate one, but I might have missed it.

However I have successfully set up the latest Qt prebuilt for Windows. Works almost out of the box, the only glitch is java version (11 won't work, need to roll back to 8).

@Domel07
check the Qt Website, the unified online installer should have the latest Linux builds

Should work.

@FRAUBRJ I am currently still stuck on linux but windows works great for me (beware of the java version, 11 does not work for me).

[Domel07]

@J.Hilk do you mean linux version? I can not find one (and the Qt download site is extremely hard to find, the information on download page are highly deceiving (and not leading to any actual downloads))

@Domel07 what about http://download.qt.io/archive/qt/ ?

[Domel07]

@J.Hilk Will try, many thanks, I have overlooked it :) Many thanks!

[FRAUBRJ]

@Domel07 Yes you are right! I installed JDK8 (http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)
and all is fine!
Thank.

@Pablo-J.-Rogina Many thanks, that's it!
