Qt for Android : QtCreator build/deploy error when executing step "Build Android APK"

Question

After some web browsing, I still can't figure out why I get the following error when I build a simple basic Qt project for Android in Qt Creator :

I don't have spaces in my paths.

Nothing is better when I skip the make install step as some related post stated. It just does not show the following lines:

Makefile:1707: recipe for target 'install_target' failed
install: cannot stat 'libtestAndroid.so': No such file or directory

System configuration:

Under Linux Fedora, as the Qt's guide states, I got :

• Android SDK tool (r24.4.1)
• Android NDK (r10e-rc4)
• Apache ant (v. 1.9 in /usr/bin/)
• Java SE Development Kit (java-1.8.0-openjdk-1.8.0.60-14.b27.fc21.x86_64)
• Qt5 for Android (v. 5.5.1)

I've installed the Android API 23 SDK tools with the ./android update sdk command:

The paths (jdk, sdk, ndk, ant) seem correctly set in QtCreator > Tools > Options > Android.

Thanks

I just re-install the NDK and it works fine now...

Sometimes it's strange...
