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

      Now the problem is elsewhere

      @BUILD FAILED
      /home/andrea/Android/adt-bundle-linux-x86_64-20130911/sdk/tools/ant/build.xml:720: The following error occurred while executing this line:

      Perhaps JAVA_HOME does not point to the JDK.

        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@

                      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)
