Android-Unable to build -Jdk Error-unable to find Jdk

Hey guys,

i realy tried out ALL of the posted workarounds to fix the goddamn message (Unable to find suitable jdk installation.)
i set the JAVA_HOME variable to

1) C:\Program Files\Java\jdk1.7.0_45\bin
2) C:\Program Files\Java\jdk1.7.0_45\
3) C:\Program Files\Java\jdk1.7.0_45\bin\java.exe

NOTHING works for me. I am using the free Unity (v 4.3.2 f1) and Java 7.045.
due to postings from august 2013 and unity v4.2 i wonder why it needs goddamn such long to fix this unfinished business by now.

common unity DEVs. why cant you implement an correct routine which searchs and finds the "§()="(§=ing JAVA installation?!

pleasepleasepleaseplease fix it or someone PLEASE tell me how to fix it by myself. solutions posted by now didnt work for me.

using win 8, 64bit
thx

 

64 bit windows + jdk 64 + Unity 4.3.2f

I have set the JAVA_HOME to

1) C:\Program Files\Java\jdk1.7.0_45\bin
2) C:\Program Files\Java\jdk1.7.0_45\
3) C:\Program Files\Java\jdk1.7.0_45\bin\java.exe

and added
C:\Program Files\Java\jdk1.7.0_45\bin
to the PATH

also with no result. Unity just refuses to find java.

However if i type java at the command line it is most certainly pathed correctly.

Is this a Unity bug am i wasting my time trying to fight it?

 

got this exception tried everything i can think of ,

System.ComponentModel.Win32Exception: ApplicationName='java.exe', CommandLine='-Xmx1024M -Dfile.encoding=UTF8 -jar "F:/Editor/Data/BuildTargetTools/AndroidPlayer\sdktools.jar" -', CurrentDirectory='C:\Users\Andy\Documents\New Unity Project'

if anyone has a clue could you help a novice please

 

this problem happen to me whenever I re install windows and I solve it by downloading JDK 32 bit even so I have windows 64....stupid Unity.

 

Problem Fixed!!!!

After trying many of the methods mentioned here, I realized I had only the 64bit version of the jdk installed. I installed the 32bit version and without any additional setup, the problem was fixed!

 

well for some reason its working now ,
all I've done was reinstall Java and now its works and that's the 64 bit version ..... go figure.

 

I uninstalled 64bit JDK and installed the 32bit, Now it works :/

 

I can confirm that after changing Comodo's sandbox settings to deactivated I had no need for any java variables and Unity compiled the apk fine. Thank you Patico!

 

solved !!!

I use Unity4.3.3 + JDK 1.7

(1)set JAVA_HOME, JDK_HOME, PATH CLASSPATH to the JDK folder ,
(2)close Unity (If Unity is Opened)
(3)Open Unity
(4) solved !!!

If Unity is running set JAVA_HOME, JDK_HOME, PATH CLASSPATH will NOT help.

 

Yes, that's it. I set up JAVA_HOME = D:\Program Files\Java\jdk1.7.0_45\ and it works. My question is where did it get the default path from and can it be edited in a Unity configuration setting?

 

Just wanted to mention that don't forget to relaunch Unity after changing System variables.
Mine worked in that way

 

Solid Solution on jdk 7!!!!

Hey guys, im running windows 8, i tried a whole bunch of the suggested solutions above..but what seems to do the trick was right licking the Jdk install, properties, under compatiblity mode, changing from "vista" to "win 7"... i ran the install again and Disco! it worked...Note i had set the Path to the above metioned method..it may or may not effect the out come..good luck

 

i`ve done all the above plus disabled the COMODO's(firewall) sand box and it works finally, so look out your security settings.

 

worked for me

I use Unity4.3.4 + JDK 1.7

 

Thank you sir, this helped me. Installed the 32-bit JDK on top of the 64 bit version.

 

Phew!

Happened to me again on new install of Win8.1 Pro. I tried many options in this thread, and this little trick described in this thread helped. So, anyone having hard time fixing Android builds giving JDK error should do this.

First, I'm on Windows8.1 with JDK1.7-64bit, installed Android Studio bundle.

- Open System Properties (Win+X -> System)
- Click Advance system settings
- Click Environment Variables...
- Under System variables list, double-click PATH
- IMPORTANT: add the JDK bin folder to START of the PATH variable, then semicolon, and rest of the path



That's all. Start Unity3D, and Build your Android game, it should compile alright.

// chall3ng3r //

 

Just for info, last one did it for me.

Cheers

 

Putting the name as JDK_HOME instead of JAVA_HOME when setting the variable worked for me.
Also, for those who don't know what the variable is about, right click Computer, go to Proprieties, then click Advanced system settings on the left, then click Environment Variables, and click New under System variables.

 

thanks...a lot !!!

 

i had the same problem, windows 8 64bits.
To solve it, you need to install java jdk for 32bits, and set the JAVA_HOME TO C:\Program Files (x86)\Java\jdk1.7.0_51

good luck;

 

I had the same problem, and this worked for me to.

Thanks

 

Thanks so much for this. Helped me fix the issue on Windows 8.1, running with JDK 1.6.

 

Thx Patico! I can confirm this, too! After uninstalling, installing, setting all environment variables, try and error => i found your answer and a bolt hit my brain!! Comodo Firewall blocked it without any sign! I think Comodo is a good firewall/antivirus package, but for this reason i hate it over all! It tricked some times in the past, just blocking something and after hours you recognize its comodo again

 

CONFIRMED!!!

just installed jdk x86 version and it worked!
tried almost all of the other solutions here but nothing worked for me.
maybe not an issue from unity but from the jdk x64 version.
i also REMOVED the variable and it still works

 

Indeed, Windows 8 64 here, unintalled and reinstalled x86 version and it worked. I didn't have to change any environment variables or anything.

Also I installed JDK 7 not 8.

 

Solved for me also.
Add in an environment variable as shown e.g. JAVA_HOME and C:\Program Files\Java\jdk1.8.0_05\.

THEN CLOSE UNITY!


This last step is what took too long to figure out!

 

My issue was simply that I had JDK set up and I forgot to install regular java... The moment I installed plain old java (www.java.com) all my problems were solved... I also went through and did the environment var changes for system.

 

I HAVE THE SAME PROBLEM BEFORE BUT I SOLVE IT MYSELF.

VERY SIMPLE!!!!!..... uninstall the 64 bit version of jdk then install the 32 bit version.. JUST DO THAT AND IT WILL WORKS!.....

 

Added 32bit version, solved!

 

solved!

I use Unity4.3.1f1 + jdk1.8.0_05

(1)close Unity (If Unity is Opened)
(2)add the JDK bin folder to START of the PATH variable


(3)Open Unity
(4) solved !!!

 

Installing the 32bit version of my JDK solved everything for me.

 

I just copied java.exe to C:\Windows folder and now everything is working fine. You can find java.exe in C:\Program Files\Java\jdk1.8.0_05\bin\. Hope this helps.

 

Just setting this all up... noticed there area few choices.... JDK 7 JDK 7 for ARM, or JDK8... which should I install ? maybe 7 to be safe, but do I need this arm version ?
thanks in advance

 

thanks,fixed

 

discovered a few things.... and some omissions from various unity/droid setup docs... here are a few notes to help other droid newbys like me...
(I'm not posting detailed info on how to do each.... you can google that, but just posting notes on some things not to forget to do!)
Same steps apply to both mac and PC

1)don't forget to install Java JDK (not JDK for arm) and match the OS version to your machine 32 or 64 bit. At time of writing this 7.1 works, I didn't try 8. Its on the oracle site.
2)install Eclipse
3)install Android SDK (and beware of the windows path too long error from .zip file, right click and copy instead of using win zip to extract worked for me)
4)Setup the environment variables JAVA_HOME and your bin folder in the PATH.
5)Don't forget to install drivers for your device (for samsung, find the app 'kies')
6)To get Eclipse to show any debug prints, you need to add "logcat" to the tabs in eclipse.
7)Don't forget to point unity to the android SDK in unity prefs.

 

I tried all the above things and it didn't help me :

Setting the environment variable
Updating jdk
Correctly specifying Android sdk folder in Edit>Preferences>External Tools

Again the error about incompatible java version was getting displayed.

So I spotted the Unity 'Editor log file' in my Windows 7. For different platforms, it's located differently-

Mac OS X - ~/Library/Logs/Unity/Editor.log
Windows XP - C:\Documents and Settings\username\Local Settings\Application Data_\Unity\Editor\Editor.log
Windows Vista/7 - C:\Users\username\AppData\Local\Unity\Editor\Editor.log


The detailed error in the log file was:

"
Incompatible java version 'C:\Program Files (x86)\Java\jre6\bin\java.exe'
C:\Program Files (x86)\Java\jre6\bin\java.exe -Xmx1024M -Dfile.encoding=UTF8 -jar
"F:/Editor/Data/BuildTargetTools/AndroidPlayer\sdktools.jar" -
stderr[
Unable to access jarfile F:/Editor/Data/BuildTargetTools/AndroidPlayer\sdktools.jar
]
stdout[
]

"


The error given in bold above caught my attention...and i went to F: ,then 'Editor' then 'Data' and couldn't find 'BuildTargetTools'.... so I made the folder, made 'AndroidPLayer' folder and this file 'sdktools.jar' which was probably missing from my version of Unity and it may be a bug, I got it from another possibly older installation of unity... luckily I had it somewhere else in my hard disks... And it worked. Don't know if this is installation fault or I had somehow deleted this sdktooks.jar or a bug in Unity but hope if u have this trouble, then may be this info would help you... Do check this log file and check the error if it was the same as mine.

 

..also..remember to reboot after setting up environment variables. and restart unity after any changes

 

I had the same issue and I believe I have figured it out.
Here is the breakdown:

If your android SDK is 32-bit (which I believe is for all of you) you need to download the 32-bit Java SDK.
32bit Java SDK is installed C:\Program Files (x86)\Java\jdk1.8.0
64 bit Java SDK is installed in C:\Program Files\Java\jdk1.8.0

You still need the JDK_HOME user variable set for Unity to compile your APK.

 

Ran and built to android a couple of days ago with official 4.6.1 release just fine.

I installed the latest Unity patch (4.6.1P4) and now I start getting this error and none of the fixes work.

This was working before the upgrade to Unity 4.6.1 patch 4 but now it's not.

I'm trying to fix a user crash due to Unity build failing on Intel android chip (which worked previously) and now I can no longer build to android to test latest patch.

*sigh*

Edit: Submitted bug report. Can you please fix this.
Bug report: http://fogbugz.unity3d.com/default.asp?664473_r78jmvm99edc9a4t

 

After pulling my hair out, smashing my head against a wall and screaming into the night scaring the crap out of the neighbours....

I installed Unity 4.6.1 P3 with the same result as P4 = FAILURE
Reinstalled Java JDK = FAILURE

Reinstalled Unity 4.6.1 and I can build to Android again

Unity, your patch build process is bugged with android and causes much horrible pain for paying customers

I need to test the patches because I have crash reports and am hoping that *maybe* the patches have fixed them...or maybe I shouldn't...

 

No problems here whatsoever, tested on OSX and on Windows: builds to Android work flawlessly...

 

Good for you! I'd love to be in your shoes.
However, due to the very existence of this thread, there appears to be a problem somewhere or other...

 

fyi http://forum.unity3d.com/threads/issue-with-version-4-6-1-p4-and-java.291546/

 

Ok, having the same issue but on MacOS 10.10, Unity 4.6.21f. Suggestions to fix on Mac?

/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java??? does not appear to work.

 

after configure Environment variable, you must restart unity,

it worked for me

 

install jdk x86 and it worked for me.

 

i updated my unity 4.6.0p1 to unity 4.6.3p4 and got this error, updated jdk to jdk1.7.0_75 but still same error. using windows 7 error detail is listed below.
Error building Player: UnityException: Unable to find suitable JDK installation. Please make sure you have a suitable JDK installation. Android development requires at least JDK 7 (1.7), having JRE only is not enough. The latest JDK can be obtained from the Oracle website
http://www.oracle.com/technetwork/java/javase/downloads/index.html
any fixes for this error in unity 4.6.3p4?

 

this not working for me

 

I was getting this error. After frustrating myself with system variables for an hour, I found that that wasn't my problem at all.

The actual culprit for me was a really old installation of Java from like 4 years ago that I didn't even realize I had (and it wasn't appearing in Java folder, either!)

I noticed it because of this line in the Unity Editor log file: "System.Exception: Incompatible java version: 1.6.0_26"

So I went to my "Programs and Features" list (Control Panel) and lo-and-behold there it was. Java 6 Update from 2011. Uninstalled and bam, no more build error silliness.

 

Just a quick post for people using Unity 5.x - Unity now allows you to set the JDK to use under "External Tools" in the Preferences window. If you know you already have the JDK installed, just browse to its location and you're all set. No amount of setting JAVA_HOME or any other environment variable will fix any problem with different java versions.

Don't make the mistake I did and spend a bunch of time setting environment stuff if you're using a newer Unity version!
