Using JDK that is bundled inside Android Studio as JAVA_HOME on Mac
android-studio, java, java-home, macos
Solution
Solution:
- (Updated 2023) For Android Studio before Electric Eel 2022.1.1 and above: `export JAVA_HOME=/Applications/Android\ Studio.app/Contents/jbr/Contents/Home`
- MacOS versions before Big Sur: add line `export JAVA_HOME=/Applications/Android\ Studio.app/Contents/jre/jdk/Contents/Home/` to `.bash_profile` file in your home directory. Run `source ~/.bash_profile` to update terminal.
- Catalina, Big Sur, Mentere and above: add line `export JAVA_HOME=/Applications/Android\ Studio.app/Contents/jre/Contents/Home` to `.zshenv` file in your home directory. Run `source ~/.zshenv` to update terminal.
After that, running `java -version` gave this output and Java started to execute normally:
openjdk version "1.8.0_112-release"
OpenJDK Runtime Environment (build 1.8.0_112-release-b06)
OpenJDK 64-Bit Server VM (build 25.112-b06, mixed mode)
As for the Android Device Monitor — it still demands this ancient JRE version 6.
Problem
I tried to open Android Device Monitor and the Studio showed me this message =-O : It surprised me, because how have I been able to develop Android apps if I didn't have any Java installed?! Actually, Android Studio comes with bundled JDK/JRE (located in `/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home`), but it is not found by the system: executed `usr/libexec/java_home` gives ``` Unable to find any JVMs matching version "(null)". No Java runtime present, try --request to install. ``` Setting `$JAVA_HOME` to `/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home` did not help — `source .bash_profile` doesn't like that it's a directory. QUESTION: I don't want to install new JDK if I already have one inside Android Studio. How do I set it as system default?
