    Did you check the JDK location in Options -> Android from QtCreator ?

      It's set to /etc/java-7-openjdk but there are not a bin folder in it and that's probably why I get

      @Error: JAVA_HOME is not defined correctly.
      We cannot execute /etc/java-7-openjdk/bin/java@

      So is that what I have to change? Change in what?

        Change it to point to the folder where you have your java executable installed

          Now the problem is elsewhere

            Maybe I should remove and reinstall java and all the components that I need to compile for android...

                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!
