[Qt-creator] Deploying to Android device fails

[Jochen Becher]

Hi,

I just installed an Android development environment. Unfortunately
deploying an app to Android devices (physical or virtual) fails. Here
are some details:

1. Building, deploying and running a simple "Hello World" project
(including some C++ code) from Android studio works for both virtual
device on emulator with X86 code and physical ARM device connected via
USB.

2. Installation in QtCreator 4.4.0 looks reasonable: I entered JDK
location (/usr/lib/jvm/java-8-openjdk-amd64), SDK location
(/home/jochen/Android/Sdk) and NDK location
(/home/jochen/Android/Sdk/ndk-bundle).

12 toolchains were found and two kits created.

The virtual device is displayed (7_WSVGA_Tablet_API_17).

Issue 1: AVD Manager cannot be started from QtCreator. Error message
is:

AVD manager UI tool is not available in the installed SDK tools
(version 26.1.1). Use the command line tool "avdmanager" for advanced
AVD management.

This is not a problem because I can use Android Studio to create
virtual devices and I can start the virtual device from QtCreator.

3. Building example "calqlatr" works for both Android kits.

4. Issue 2: Deploying the example fails:

Cannot find the android build step.
Error while building/deploying project calqlatr (kit: Android for x86
GCC 4.9, Qt 5.9.0 for Android x86))
When executing step "Deploy to Android device"

(Same error message for ARM kit).

When I look into Projects / Run Settings the deployment step "Deploy to
Android device" exists.

There is nothing filled into the Run configuration (only empty "Custom
Executable" is shown) but I assume that is correct for Android devices,
isn't it?

Any hints?

BTW, is it possible that the QtCreator documentation is wrong? In
"Deploying Applications to Android Devices" an Ui element "Projects >
Build Android APK > Details" is mentioned. I cannot find it and also
the screenshot of the details looks completely different from mine
which lists "Uninstall previous package", "Reset Default Devices",
"Clean Temporary Libraries Directory on Device" and "Install Ministro
from APK" only.

Issue 3: When I press the button "Clean Temporary Libraries Directory
on Device" QtCreator crashes immediately.
