      Since you just installed it, you could try to just logout/login to check wether your environment has been properly updated.

        I removed java 6, reinstalled java 7 and then logout/login

        I retry and I get
        @23:26:32: The process "/usr/bin/make" exited normally.
        23:26:32: Copy Qt app & libs to Android package ...
        23:26:33: Creating package file ...
        23:26:33: Package deploy: Running command '/usr/bin/ant clean debug'.
        Error: JAVA_HOME is not defined correctly.
        We cannot execute /etc/java-7-openjdk/bin/java
        Packaging Error: Command '/usr/bin/ant clean debug' failed.Exit code: 1
        Error while building/deploying project Test (kit: Android for arm (GCC 4.6, Qt 5.1.1))
        When executing step 'Packaging for Android'@

        So I have to set JAVA_HOME.
        Now, I have to add:

        @export JAVA_HOME=/usr/lib/jvm/SOMETHING@

        But something what? I post the content of /usr/lib/Jvm
        @default-java java-1.7.0-openjdk-amd64 java-6-openjdk-common
        java-1.6.0-openjdk java-6-openjdk java-7-openjdk-amd64
        java-1.6.0-openjdk-amd64 java-6-openjdk-amd64 java-7-openjdk-common
        @

        and then, I have to add the line in which file? .bashrc? .profile?

        Thank you for the help....

          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@

                                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

                                        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.
