What's the problem? android compile error

ManSon

Hi every one
I'm studying to make an Android app using QT..
After creating a sample project with a test, I tried to android build, but an error occurred.

BUMP!

Anyone?!?

I've got the same frustrating problem! I can create apps using Android Studio, I can create desktop QT apps.... but everything I try to compile a QT Android app fails with a similar failure:

FAILURE: Build failed with an exception.

I messed around with various settings, ended up uninstalling and re-installing... still doesn't work!

It would be great to get this working!

Ok, finally got mine to work. What a %@$# PITA... I really dislike windows, but it's where I chosen do android dev unfortunately.

So... here's what I did... (it may have just been one of these that fixed the issue, but I'm too tired to go back and test them individually)

1st: correct some invalid variables in QT's build settings/build environment (i.e. wrong slash was / instead of \)... AND add some. Specifically:

ANDROID_HOME = D:\Android-SDK
ANDROID_SDK_ROOT = D:\Android-SDK
GRADLE_USER_HOME = C:\Users\pc\.gradle
JAVA_HOME = D:\Program Files\Java\jdk1.8.0_201

(obviously these need to be upd for your install directories .i.e usually on C: drive)

Note: I specified these in Windows env settings, but it seems like they need to be specifically set in QT's env overrides.

2nd: remove the 29.0.0RC1 from Android SDK build-tools via Android Studio SDK manager. Apply.
Select 'show package details' to then be able to select the 28.0.3 version. Apply.

3rd: go into theQT project/app's folder and edit the gradle.properties file... change the line to:

androidBuildToolsVersion=28.0.3

Finally: you should probably should close and reopen QT and the project.
Build/deploy should now (hopefully/finally) work!

@Jay_M

Thank you for solving this problem.
Thank a ton.

@Jay_M You made my day!

Eddy

Hi Jay_M,

Thanks for the solution! Now I can take the jump to Qt5.12.3 with my Android project

I tested your workarounds and the only thing you have to do is step 3:

3rd: go into theQT project/app's folder and edit the gradle.properties file... change the line to:

androidBuildToolsVersion=28.0.3

I tested on some test applications and also on a real world application
You saved me a lot of time! Now you can save some time for your other projects with less tweaking ;-)

Eddy

@Eddy if you have build-tools 28.0.3 downloaded. I just deleted build-tools 29.0.0 and downloaded 28.0.3 (and do not change build folder - it configures for the only one 28.0.3 version which I have).

Eddy

Hi Nikich,

good find!

I just tested with a new project and deleting the 29.0.0 folder upfront makes Qt Creator find the 28.0.3 folder automatically.

Thanks for posting this back here ;-)

I have a similar problem. I followed the instructions of the tutorial for android and opened the analog clock example to build, deploy and start the app in the Android emulator.

I use Qt Creator for macOS with the newest suggested Qt versuin. I get following build errors:

/Users/burks/Library/Android/android-ndk-r20/toolchains/x86-4.9/prebuilt/darwin-x86_64/lib/gcc/i686-linux-android/4.9.x/../../../../i686-linux-android/bin/ld: error: cannot find -lc++
clang++: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [libshadereffects.so] Error 1

Some ideas, how to make a Qt app for Android running?

Hi,

I have exactly the same issue. Google Play Console requires adaptation for android-28 and arm64-v8a
from August 19, so QT developers cannot use r16b anymore and I have used NDK r20 instead. Unfortunatelly I received -lc++ library linking problem. I am not sure why, because the library is available in the expected path, and objdump returns correct armv7 architecture.

To solve the issue with linking I just used android-ndk-19c version. But note, that the 19c contains some bug with support of spaces in the QRC paths, so for example I had to remove this from the QRC:

make[1]: *** No rule to make target '/project/fonts/customfont/pobrano z /project/fonts/customfont/koikj.txt', needed by 'qrc_qml.cpp'.  Stop

Albertino

The error: cannot find -lc++ using ndk r20 can be solved like this:
https://codereview.qt-project.org/c/qt/qtbase/+/264903/9/mkspecs/android-clang/qmake.conf#34

For example to compile for android armv7 ndk r20, locate the file:
C:\Qt\5.13.0\android_armv7\mkspecs\android-clang\qmake.conf
and add the missing -nostdlib++
for android x86 (i use this for emulator), locate the file:
C:\Qt\5.13.0\android_x86\mkspecs\android-clang\qmake.conf

For error: Execution failed for task ':compileDebugAidl'
locate the file on your build directory, mine is: C:\dev_qt\experiments\build-test_qt_5_13_0_ARMv7-Release\android-build\gradle.properties and change androidBuildToolsVersion
from: androidBuildToolsVersion=29.0.0
to: androidBuildToolsVersion=28.0.3

@Albertino Thank your very much. Now I can build and run the calculator example project with the emulator. That's very motivating. However I get many warnings in the log. Maybe the example projects are not optimized for Android. I will check the tutorial a hallo world project.

@a.burks these are info/debug messages (not errors), QT is very verbose on android. You can ignore them

@Albertino Gracias!! . estuve 2 semanas para arreglar ese error.

It's you project folder where the source code is.
