    You should not have a semi-colon in your JAVA_HOME path.

    Did you set it globally ? i.g. in your .profile file ?

    If not, it won't be available to program run outside the console where you set it.

        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

                    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:

                              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'.@

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