A few days ago I tried to install the Android Studio editor on Fedora linux and I can not.
I searched in some tutorials, sites, google and could not find a solution to deal with the error below:
ERROR: Can not start Android Studio \ nNo JDK found.
Please validate either STUDIO_JDK, JDK_HOME or JAVA_HOME environment variable points to valid JDK installation.
Any ideas how to solve this problem?
Open the file studio.sh and add JAVA_HOME directly to it
UNAME = which uname
GREP = which egrep
GREP_OPTIONS = ""
CUT = which cut
READLINK = which readlink
MKTEMP = which mktemp
RM = which rm
CAT = which cat
TR = which tr
JAVA_HOME = /usr/java/latest
For a complete evaluation of your problem, here are some things you need to check to make sure you have what it takes:
Instructions for Fedora Linux
Verify that you have the jdk package installed:
rpm -qa | grep jdk
If it is not installed, you will have to install it:
Switch to root
sudo -i
## ou ##
su -
Install the package you downloaded
## JDK 32-bit ##
rpm -Uvh /caminho/para/binario/jdk-7u51-linux-i586.rpm
## JDK 64-bit ##
rpm -Uvh /caminho/para/binario/jdk-7u51-linux-x64.rpm
## JRE 32-bit ##
rpm -Uvh /caminho/para/binario/jre-7u51-linux-i586.rpm
## JRE 64-bit ##
rpm -Uvh /caminho/para/binario/jre-7u51-linux-x64.rpm
Check the current installation:
java -version
It should look something like this:
java version "1.7.0_51"
Java (TM) SE Runtime Environment (build 1.7.0_51)
Java HotSpot (TM) 64-Bit Server VM (build 22.1, mixed mode)
Check which compiler:
javac -version
It should look something like this:
javac 1.7.0_51
Adds JAVA_HOME to the environment variable:
Most common is to edit the .bashrc file in your user directory:
gedit ~/.bashrc
And add to the end of it:
JAVA_HOME=/usr/lib/jvm/java-<versão>
Note: After this you may need to re-log in for the changes to be made.
Your problem is usually in the form of a permissions issue.
Try changing the permissions of the folder:
chown -R root:root /caminho/para/android-studio

>Dude I broke my head but I got it in win7 that had the same problem, the solution was computer > system_name > environment_variables > Then I had to create a new one in New => variable name: JAVA_HOME value of the variable: C: \ ProgramData \ Oracle \ Java \ javapath; C: \ Program Files \ Java \ jdk1.8.0_11 This "value of variable" is the same as the variable "PATH" found on the same screen of variables just put in edit and copy that field. I hope in order to resolve it
Do the following:
1) Install JDK, Download Here
2) View the installation directory. To do this open the console and type the following command:
rpm -q -filesbypkg jdk
In my case it was /usr/java/jdk1.8.0_11/ .
3) Open the file studio.sh and add the line JAVA_HOME
UNAME=which uname
GREP=which egrep
GREP_OPTIONS=""
CUT=which cut
READLINK=which readlink
MKTEMP=which mktemp
RM=which rm
CAT=which cat
TR=which tr
JAVA_HOME=/usr/java/(seu directório, no meu caso jdk1.8.0_11)
4) Save the file. Done!
