JAVA_HOME is not defined correctly.

Now the problem is elsewhere

@BUILD FAILED

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

SGaist

Where is javac to be found ?

p3c0

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

vanpivix

Ok, so:

@$ which java
/usr/bin/java
@

vanpivix

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'.@

p3c0

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

vanpivix

Yep it's installed:

@sudo apt-get install openjdk-6-jdk
[sudo] password for andrea:

p3c0

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 )

vanpivix

Ok so I have to add
@export JAVA_HOME="/usr/lib/jvm/java-6-openjdk-amd64/bin"@

but where? in .profile? .bashrc?
Thanks

p3c0

Yup. try in bashrc or /etc/environment

vanpivix

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...

vanpivix

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...

p3c0

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.

vanpivix

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!

p3c0

Yes. You can try asking in new post with appropriate details

vanpivix

I've done it, thanks all 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)
