Cannot find the android build step.
Error while building/deploying project calqlatr (kit: Android for armeabi-v7a (GCC 4.9, Qt  (android_armv7)))
When executing step "Deploy to Android device"

I had also post this on stack-overflow . here is the link:- https://stackoverflow.com/questions/50434018/cant-run-android-app-in-qtcreator?noredirect=1#comment87888043_50434018

I solved it by removing ~/.config/QtProject/ which deleted configuration and reinstalling qt for android using online installer . it seems like my installation was corrupted

hey have you properly setup your Qt SDK, NDK and apache ant ?? . also if you compile your project the apk can also be found in build directory of your project .

something like this
/home/whatever_name/build-app-Android_for_armeabi_v7a_GCC_4_9_Qt_5_9_0_for_Android_armv7_c6c308-Release/android-build/bin/

I have set up everything including jdk,SDK and NDK. I have installed apache-ant by

sudo pacman -S apache-ant

Here is the screenshot:-

Also there is no android-build/bin folder in build directory :-

here is what I all have in build directory :-

% tree

0 directories, 8 files

Also I have setup all Android NDK environment variables.

Also everything works under Android studio. I can build and create android apps and run them on my physical device in android studio

Did you activate the USB Debug mode in the physical phone?
Do you have the phone drivers installed?

Yes.

Do you have the phone drivers installed?

No. Its runs perfectly with android studio .

I also had armv7a emulator image which works in android studio. In qt-Creator , it didn't event ask me to run app in emulator .

i am not sure what's the problem but here is my setup and it works perfectly fine . Maybe you can try this one out :)

1. using Qt5.10.0 ( offline installer)

2. i have created a qt_android folder : all the SDK and NDK and apache ant resides here.
   

3. my qt creator settings
   

..

4. also have you ran android sdk manager atleast once ?? to get the necessary tools .

5. try to build a sample example provided by Qt itself .

Hi, as I remember, I had same issue, see https://bugreports.qt.io/browse/QTCREATORBUG-20088 and I fixed that (see my link).
