Building QT Application for android device

[jiji]

Hi, I have a problem when I try to connect my application for android device:

Android build platform: android-25
Install to device: No
Buildfile: build.xml does not exist!
Build failed
Building the android package failed!

Can you help me please!!

@jiji I guess you mean compile/build not connect?
The information you provided isn't enough to say what is wrong. Please provide the whole build log.

@jiji Are you building using Ant? If so switch to Gradle (you can do it in your project settings).

@jsulm ,I switch to Gradle, but nothing changed.
Those are my settings:
