Android Studio error after ./studio.sh

Question

After ./studio.sh in a terminal I get this error \"tools.jar is not in android studio classpath Please ensure JAVA_HOME points to JDK rather than JRE\"

Answer 1

I have figured it out. You need to install openjdk-jdk. Opensjdk-jre is not enough. So in terminal all you need to do is write sudo apt-get install openjdk-7-jdk then press yes. Open the android studio bin folder, double click on studio.sh, open in terminal, press enter, and then android studio should work.

Answer 2

the solution for me was to modify studio.sh and add JAVA_HOME as a variable:

# ---------------------------------------------------------------------
# Locate a JDK installation directory which will be used to run the IDE.
# Try (in order): STUDIO_JDK, ../jre, JDK_HOME, JAVA_HOME, "java" in PATH.
# -------------------------------------------------------------------

     JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-i386/

if [ -n "$STUDIO_JDK" -a -x "$STUDIO_JDK/bin/java" ]; then (etc..)

Answer 3

This below trick work for me , Check your app dependencies in build.gradle(Project:AppName) .

Try the latest build.gradle version.

classpath 'com.android.tools.build:gradle:2.2.1'

Answer 4

You have to have the latest JDK. I solved it by
   sudo apt-get install openjdk-8-jdk
(Note the '8' in there)

Answer 5

This is what I did to solve the problem:

cd /opt/ (where android-studio directory is located)

sudo chown -R your_user:your_user android-studio

(where your_user is... yes your username :) )

Answer 6

This seems like permission problem. Someone who packed Android Studio, has the original files under non-root account. If you unpack it as root, the files and dirs has no permission for "other" (just for owner). The person who is packing Android Studio knows a lot about Android and Java, but not much about Unix permissions (uch!). There are two possible solutions:

a) unpack android-studio-bundle-...-linux.tgz as normal user, not as root (this has an advantage - you will be able to update Andriod Studio by clicking menu; but this is generally stupid because you are open to malware attack)

b) fix read permissions for files and dirs for whole android-studio directory with something like: chmod -R +r /opt/android-studio
