JDK and Android Studio

Very recently, Google released the first stable release of Android Studio and I have installed the Oracle JDK following this instructions.

Code:

pedro@slack:~$ which java

/usr/lib/java/bin/java



pedro@slack:~$ ls /var/log/packages/ | grep jdk

jdk-8u25-i586-1

However, Android Studio couldn't find it so I've tried setting it manually. I've pointed it to /usr/lib/java and Android Studio didn't complain (it does complain when the directory is not a jdk one). But when I try to create a project it says it couldn't determine the Java version. Any help?

Have you logged out and logged back in? Java needs environment variables set and that's typically done on login (you can source your login files, but I can't remember which ones are needed for java).

Yes, I've done that. JDK was installed several days ago.

I know building CyanogenMod requires OpenJDK instead of OracleJDK. I just read the requirements and it states to use Oracle's, however, it states to use version 7, not 8, so that's likely your problem. I had to downgrade my java to v7 to compile CyanogenMod.

Well, I am using 'jdk-7u71-i586-1' now and same problem.

What happens if you start it from the command prompt? Any useful output? I won't be able to test this until I get home.

You mean, going to the bin directory and running "./studio.sh"? That is what I do.

Android Studio is using java from gnu, not from oracle. Check if you have the script /etc/profile.d/jdk.sh and that it is executable.

It is there and it is executable. This makes no sense, I've pointed the JDK path on Android Studio settings to "/usr/lib/java", it didn't complain about it.

Also, 'which java' returns "/usr/lib/java/bin/java"

What is the output of

Code:

ls /var/log/packages/ | grep jre

There is no need to install the jre if you install the jdk.

I know, but I'm guessing you have open jre installed

Hello,

If /etc/profile.d/jdk.sh is here and executable, then what's the output of :

Code:

$ java -version

if the output is: java version "1.7.0_71", your jdk installation is OK, and the problem comes from android studio which uses the wrong jdk, and you'll have to redefine the path to the JDK to use in :

File->Other Settings->Default Project Structure->SDKs

Note: the option path above is from an older version of android-studio, so it can be elsewhere.

I don't. All I have installed is Oracle's JDK.

java -version outputs:

Code:

java version "1.7.0_67"

Java(TM) SE Runtime Environment (build 1.7.0_67-b01)

Java HotSpot(TM) Server VM (build 24.65-b04, mixed mode)

Well, for some odd reason the SDK was set to /usr/lib/jvm (I've set it to /usr/lib/java during the first launch and it set it to somewhere else). I've set it again to /usr/lib/java and now works fine. Except for the fact the Linux version is still really slow :(
