Building Qt for Android platform from sources.
-
@Hithendra are you sure you need to build Qt for Android from sources yourself? I guess that installing a Qt for Linux release with Android support will provide the libraries required by the openAuto project directly. For instance, I installed Qt 5.9.0 for Linux x64 (qt-opensource-linux-x64-5.9.0.run) and checking the files installed, I can find libraries for Android already made:
pablo@lubuntu64:/opt/Qt5.9.0/5.9/android_armv7/lib$ file libQt5Multimedia.so libQt5Multimedia.so: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /system/bin/linker, not stripped -
@Pablo-J-Rogina Thanks for the reply.
I thought building from the sources is the only way to get the qt libraries for android.
I will try the installation for linux with android support.Thanks alot ...
@Hithendra Simply use Qt online installer and select Qt for Android there...

@jsulm Thanks. I am trying that. Do I need to select source components also? I need mainly bluetooth and multimedia modules?
@Hithendra If you don't need Qt sources then there is no need to select source components. Bluetooth and multimedia are already part of normal Qt installation.

@jsulm Is it possible to build Qt libraries for 64 bit arm v8?
I would like target for android nougat device.The issue I am facing when I tried to link the Qt5 libraries generated as mentioned by you (using Qt online installer) is link error as below:
/home/Qt_Nougat/5.11.0/android_armv7/lib/libQt5MultimediaWidgets.so: error adding symbols: File in wrong format.Please help?

@Hithendra you mentioned before
Android API level as 18.
and also it looks like you installed latest Qt 5.11 with Android components
/home/Qt_Nougat/5.11.0/android_armv7/lib/
So is it working for such Android level 18?

@Hithendra Sure, you can build Qt. But it is no an easy task.
See https://wiki.qt.io/Building_Qt_5_from_Git

@Pablo-J-Rogina I am able to successfully install that for API level 18.
Now, I am targeting API level 24 on 64 bit device. I tried to link the old libs for API level 24 onto 64 bit device. Then I got the error message while linking.@Hithendra Ok, so for using Qt's 32 bit libraries for Android (see my first post where it shows ELF 32-bit...) without recompiling the whole Qt platform for Android 64 bit this answer may shed some light...
