      Can you post what you get when you fire "which java" command from the terminal ?

          If I retry from QtCreator, from Compile Output everything seems ok but I get:

          Application Output
          @Starting remote process.Unable to start 'org.qtproject.example.Test'.@

            i think you also need to install the jdk.
            Try @apt-get install openjdk-6-jdk@

              Yep it's installed:

              @sudo apt-get install openjdk-6-jdk

                Try setting JAVA_HOME to "/usr/lib/jvm/java-6-openjdk-amd64/bin"
                As it contains both javac and java (symbolic link to ../jre/bin/java )

                      Done. Now if I run...

                      "Application Output":http://pastebin.com/eqJCfW9p

                      "Compile Output":http://pastebin.com/bGSZmun5

                      I think it's not a Java problem anymore...

                        I'm not understanding anything.

                        Last update, every time I click on "run" I get

                        Application Output:
                        @Starting remote process.Unable to start 'org.qtproject.example.Test'.@

                        and General Messages
                        @Could not read qmake configuration file /home/andrea/Qt5.1.1/5.1.1/android_armv7/mkspecs/android-g++/qmake.conf.@

                        Maybe this is the problem now, I've never checked this tab before...

                          Well from the compile output it seems that the APK has been created
                          @/home/andrea/Code/QML/Test/android/bin/Test-debug.apk@
                          But on deployment to the emulator it crashes due to some OpenGL issues.
                          I donot have much detailed idea about this.
                          But just try to deploy this APK on a physical device and see if it works.

                            I tried in a physical device and it works!!!!!!!

                            But I can't reupload the apk every time to check if it's working well....so maybe I should open a new topic for this issue, what do you think?

                            Thanks a lot for the help!

                                  I also struggled with the "Buildfile: build.xml does not exist!". It was because I only installed openjdk-7-jre. openjdk-7-jdk is also required.

                                  Qt Creator kept saying "/usr/lib/jvm/java-7-openjdk-i386" was invalid for the JDK location. I guess it looks for something that openjdk-7-jdk puts in the /usr/lib/jvm/java-7-openjdk-i386. After installing openjdk-7-jdk, Qt Creator was happy with the location.

                                  (Using Kubuntu 14.04, JAVA_HOME set in /etc/enviroment)
