Says on my eclipse "Unable to locate executable for jre1.8.0_77". It also deleted the JREs :( I tried to run my project and went into Windows and preferences to add it but I couldn't.
Go to Windows > Preferences.
Locate Java > Installed JREs. (Or simply type JREs in the search
box).
The screen will show the list of JREs.
Click on Add button, locate the new folder on your machine and select.
Remove the old JRE from the list.
Same Question has asked before and here's the Link - How to change default JRE for all Eclipse workspaces?
Maybe you updated Java version but your PC's environment variable for JRE is still referring to the old version of JRE. If you updated Java, update your environment variable also.
recently i encountered same issue,
this happened after i updated my jre
because of this there was mismatch with jdk and jre versions
uninstalled java and installed newer JDK (SE ) kit. https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
now both jdk and jre are same

I'm starting up a new project in Intellij IDEA and when I go to select a JDK all that shows up is JDK 16.0.1 and I need JDK 8 (already installed) So I click "add JDK..." I browse through my files and I'm only able to locate JDK 16. NOTE: JDK 8 is on my desktop
Multiple JDK environment variables cannot be configured on the same computer at the same time, but we can change the value to the corresponding JDK installation directory by modifying JAVA_HOME in the JDK environment variable:
I have tried a few things including changing JDK_HOME to the current JDK, removing all jdk and installing jdk8, and reinstalling android studio, but the same issue persists.
I have used the program before and it was working a few days ago
(After wasting half a day on it, finally, I got it running)
I am running it on Windows 8.1. Also, I had JDK 1.7.0_13.
I tried the following:
Open Start menu > Computer > System Properties > Advanced System Properties In the Advanced tab > Environment Variables
Add new system variable JAVA_HOME that points to JDK folder, C:\Program Files\Java\jdk1.7.0_13
Just to be on the safer side, also add new system variable JDK_HOME that points to JDK folder, for example, C:\Program Files\Java\jdk1.7.0_13
Append new PATH in system variable that points to JDK folder, C:\Program Files\Java\jdk1.7.0_13
But still it didn't work. Then it struck me that might be, my Java version is old. I downloaded the latest version from here.
I uninstalled JDK 1.7.0_13 and installed version 8 i.e. JDK 1.8.0_131.
Now do all the above steps but, replace the path with C:\Program Files\Java\jdk1.8.0_131\ OR whichever your latest version is.
Success!! Now it works.
I've been having
Exception in thread "main" java.lang.UnsupportedClassVersionError: Unsupported major.minor version 51.0
So I looked it up, and then updated both my JRE and JDK to 8th version.
But above the console, it displays:
System/Library/Java/JavaVirtualMachines/1.6.0 JDK ....
How do I make my Eclipse run in 8th version of JDK and JRE?
And do I need to change anything in my projects after upgrading?
Thanks in advance!
In Eclipse:
Select pull-down menu: Windows > Preferences
On left, select Java > Installed JREs
Click "Add..." and browse to your JDK/JRE folder
Rename if desired, e.g. change "jdk1.8.0_51" to "jdk1.8"
Repeat if you want access to more JDK/JRE versions in Eclipse workspace
Check the JRE you want to be the default for your projects
On left, select Java > Compiler
Set compliance level to match the default JRE
Note: If your projects don't use the workspace default, then you need to update the project Properties.
Eclipse itself is running with the default Java, i.e. the java on your PATH. If you want Eclipse to run using a different JDK/JRE, you need to edit the eclipse.ini file. See the link provided by Tarun Gupta.
In Eclipse you have to change the Java location like below steps
Check for:
1) Proper java environment variable setup.
2) Right click on Project name in Project Explorer in Eclipse. Click on Build Path -> Configure Build Path. Check for proper path for Java Build Path.
Also check whether the latest version of Java is selected in Java Compiler -> Compiler Compliance Level.
3) Check from command line which Java is installed by typing java -version or java.
(Sometimes Java installed from command line in Linux systems installs old versions)
I have ADT Installed. v23.0.2.
I tried to import simple java project, but found no installed JRE to compile the code. I then installed JDK & JRE from Java SE downloads. I yet don't see any JRE in the list. Anything am I missing? any hooks ?
If it does not find it "automagically" then you need to "Add" it or "Search" it. Most likely though, when you installed the JRE, it was not properly added to the "path" or another install problem.
See this post:
How to install JRE 1.7 on Mac OS X and use it with Eclipse?
Chances are "Search" will do what you need.
I went to the Oracle site, downloaded and installed Java Platform (JDK) 7 on a Windows 7 64 bit virtual machine. I added the path to the c:\program files\Java\jdk1.7.0\bin to the path environment variable. I even deleted c:\windows\system32\Java.exe as recommended by someone. I was essentially following this: "Android Create" call fails in windows 7 - missing JDK
When I install the ADT it gives me the error JDK could not be found. Download the latest JDK. Why?
Thanks.
this is caused because the Android DK finds java in the c:\windows\system32\ folder before it finds the JDK one.
To resolve this edit your PATH environment variable and put the JDK path before the c:\windows\system32\ path.
Just in the ADT installer , press back when the installer promite for No JDK Found then press next, the installer will find the JDK, for sure this is a common bug
Does that happen when you open eclipse?
I'm thinking in two possible problems. Here is one possible solution: Eclipse - no Java (JRE) / (JDK) ... no virtual machine
If you already got this, go to Window -> Android SDK and AVD preferences
The first "preference" should ask you your Android SDK folder. you need to set this correctly.
Your JDK installation is not proper.
Reinstall JDK. It should be working fine.
I also had this problem once. I have done the above to resolve this issue.
You should not delete C:\Windows\System32 folder for this issue, It might lead to OS problems.
adil's answer is the one which finally worked for me (although I had added the jdk\bin to the path and created\set the JAVA_HOME to the same); moving the jdk\din directory before the win\sys32 in the PATH finally allowed me to install the android sdk on win7/64bit
