Today I installed Android Studio but when I opened it raised the error:
'tools.jar' seems to be not in Android Studio classpath. Please ensure JAVA_HOME points to JDK rather than JRE.
I have already installed JDK from the Ubuntu Software Center but I decide to remove it and reinstall it by command-line following these instruction. The guide that I follow for remove it is that answer, this and this. How can I uninstall it? I know that it is installed for the output of
java -version and
Here any information:
dpkg --list | grep -i jdk command gives nothing
java -version gives:
The program 'java' can be found in the following packages: * default-jre * gcj-4.6-jre-headless * gcj-4.7-jre-headless * openjdk-7-jre-headless * openjdk-6-jre-headless Try: sudo apt-get install <selected package>
javac -version gives this:
`TThe program 'javac' can be found in the following packages: * default-jdk * ecj * gcj-4.6-jdk * gcj-4.7-jdk * openjdk-7-jdk * openjdk-6-jdk Try: sudo apt-get install <selected package>
if I run
ls /usr/lib/jvm it says that there isn't such directory.
I would like to remove JDK and JRE before install packages. How can I do that?
