rated 0 times [ 9] [ 0] / answers: 1 / hits: 29066 / 2 Years ago, sat, february 5, 2022, 4:44:55

I have just downloaded the Android Studio and when I try to run ./studio.sh it gives me an error of

'tools.jar' seems to be not in Android Studio classpath. Please ensure JAVA_HOME points to JDK rather than JRE

I have checked /usr/lib/jvm/java-1.7.0-openjdk-amd64 this folder java is there and I have set the environment variables in

/etc/environment

as

JAVA_HOME="/usr/lib/jvm/java-1.7.0-openjdk-amd64/"

but still, the same error is coming, Please help me out,

after saving this file, if I check

echo $JAVA_HOME

nothing comes and when I try

source /etc/environment

it comes as

JAVA_HOME: command not found

How should I proceed?

I got the same error when trying to run the android-studio beta installation. I tried various options, but the one that worked for me was:

sudo apt-get install openjdk-7-jdk

Didn't have to do anything else.

But, I am surprised that

java -version

listed the same 3 lines before and after the jdk install:

java version "1.7.0_55"  

OpenJDK Runtime Environment (IcedTea 2.4.7) (7u55-2.4.7-1ubuntu1~0.13.10.1)  

OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode)

and

echo $JAVA_HOME

outputs blanks, but now the android-studio is running.
