Qt Android Deployment Error: Cannot find the androiddeploy Json file

I am having issues on deploying my android application to my phone. This error will pop up whenever i try to release my application (Error: Cannot find the androiddeploy Json file.). And i have checked my all my development kits and it seem that Qt had approved its settings. Thanks.
Cannot find the androiddeploy Json file.
Error while building/deploying project swipe (kit: Android for armeabi-v7a (Clang Qt 5.9.8 for Android ARMv7))
When executing step "Deploy to Android device"

I do not know if it helps, but I faced the exact same problem and I solved it by just unchecking the "Shadow build" checkbox under "Build settings" (ctrl+5). After that, everything worked.
Target device: Lenovo tabM10 FHD plus
Qt version: 5.15.2
Qt Creator version: 4.14.2

Can't run android app in QtCreator

I am trying to run Android app in Qt-Creator .when i try to build it , it builds without any problems but when I hit run button , instead of asking where to run app it gives me this error :-
Cannot find the android build step.
Error while building/deploying project untitled (kit: Android for armeabi-v7a (GCC 4.9, Qt (android_armv7)))
When executing step "Deploy to Android device"
I am using Arch Linux . I had install Android SDK and NDK and OracleJDK 10.
I had connected my Karbon Titanium phone via USB to my laptop and enabled the USB DEBUGGING .
EDIT:-
Here are environment variables:-
% cat /etc/environment

Also I am using NDK 10e:-

you have to use Qt version 5.9.0 with sdk 26.1.1 and ndk version 10.4.0.
earlier version than 5.9.0 of qt will not work with sdk 26.1.1.
so you just need to update your Qt version to 5.9.0.
At Last, Use This Combination:
Jdk version : 1.8.0
SDK version : 26.1.1
NDK version : 10.4.0
Qt version : 5.9.0
it works for me. hope it will work for you. :)

It works for me.
Just delete Qt creator settings files and restart it:
Where does QtCreator save its settings?
On Windows 10, 8, Vista and 7, the files are located in
:\Users\\AppData\Roaming\QtProject and
:\Users\\AppData\Local\QtProject.
On Windows XP, the files are located in :\Documents and
Settings\\Application Data\QtProject and :\Documents
and Settings\\Local Settings\Application Data\QtProject.
https://bugreports.qt.io/browse/QTCREATORBUG-20088
A problem was solved when I re-created the QtC settings from scratch.
So, something wrong in QtC code, related to the settings update,
because, as can see from my screenshoots, the QtC reported that all
Android configuration is OK, but the build step was not created.

Qt Android Application Execution failed

I'm learning developing Android Application by Qt Creator (v4.1.0 Community). When I build my sample app, there's no issue but when I run it with Android x86 Kit (GCC 4.9, Qt 5.7.0), it's failed and I get this message from Compile Output Console (it still runs well when I run with Desktop Qt 5.7.0 MinGW 32 bit):
'C++' is not recognized as an internal or external command, operable
program or batch file.

Can anybody explain me what I do wrong or give some ideas to solve it. Thanks for any help.

Do you see your Android kit get detected automatically ? or was it added by you manually. I would suggest to try the thing I mentioned below and see if that helps.
On Projects, Build Android APK, change the Android build SDK to newer version as shown in the picture below:

Qt 5.4 Windows Host Android Error while building/deploying project

I already have made a project with Qt and I wanted to build on Android.
It worked fine, but since I use another Workstation, I can't deploy my application.
I get the following log output :
17:50:53: Could not start process "mingw32-make" INSTALL_ROOT="D:\Projects\Qt\Comp\build-proj-Android_for_armeabi_v7a_GCC_4_7_Qt_5_4_1-Release\android-build" install
Error while building/deploying project Proj (kit: Android for armeabi-v7a (GCC 4.7, Qt 5.4.1))
When executing step "Copy application data"
I checked my kits. All seems good.
My SDK and NDK works well, everything seems to work with Xamarin for example.
Regards,

Had the same issue, solution was to add the mingw32-make to the PATH variable,
missed this originally as i had already added it as an override for the Make build step and thought that would be enough.

Using Qt Creator for non-qt Android c++ development

I'm trying to setup Qt Creator for Android C++ development that uses non-Qt libraries. Testing with a simple Hello World, I have a problem in deploying the compiled program to AVD through Qt Creator. The deployment process always stuck with an error message of;
Install to device: emulator-5554 No platform plugin, neither
libqtforandroid.so or libqtforandroidGL.so, included in package.
Please include one. 06:34:06: The process
"/home/dev/Qt5.3.0/5.3/android_armv7/bin/androiddeployqt" exited with
code 12. Error while building/deploying project helloworld (kit:
Android for armeabi-v7a (GCC 4.8, Qt 5.3.0)) When executing step
'Deploy to Android device'
How should I go about it?
Thanks.
