Qt Creator Android error “Platform SDK installed”

Question

I am developing Qt Cross platform application for Android, recently i have updated Qt creator and Installed new Qt version. I am using \'Qt Creator version 4.5.0\'

Answer 1

After lot of effort I am able to fix this issue, thanks to Mohammad Kanan, Vesafary who's answer made me get closer to Answer, Actual issue resolved with the following steps. It may be helpful who are facing the same issue In Ubuntu or may work on other platforms as well.

1. First Step is (as most of the answers suggest) changed from JDK 9 to JDK 8. I am using Java version "1.8.0_152".
2. Step 1 didn't help me (Qt creator Persist some Settings), so i removed complete Qt 5.8,5.9,5.10 installation (Using Qt Maintainace tool) and following 2 links Uninstall Qt Completely, Uninstall Qt Creator.

and did Instalation again. May be your problem get resolved at this step.

3. Step 2 also didn't help in my case, QT Creator still persist few settings and need to reset Qt creator settings. That can be done by deleting data in this folder

   ~/.config/QtProject ~/.config/Qt file ~/.config/QtProject.conf

path may be different in different System and OS. following links will be helpful in this case.
