I have had to install Java and Android on my new machine. I've downloaded jdk1.6.0_27. It's installed in C:\Program Files\Java\jdk1.6.0_27.
I've set the classpath env var to C:\Program Files\Java\jdk1.6.0_27\lib and the path var to C:\Program Files\Java\jdk1.6.0_27\bin. in cmd java - version works fine.
When i try to download Android, it checks to see if java is installed first. It's stating java not installed on my machine. I can't proceed with the Android download. Is there a reason for this?
Thanks,
Matt
This sounds crazy, but it works.
When that happens: press back, then next. I'm dead serious. It will detect java the second time around. I have no idea why.
As verified here:
Android SDK installation doesn't find JDK
I had the same problem, tried all the solutions but nothing worked. The problem is with Windows 7 installed is 64 bit and all the software that you are installing should be 32 bit. Android SDK itself is 32 bit and it identifies only 32 bit JDK. So install following software.
JDK (32 bit)
Android SDK (while installing SDK, make sure install it in directory other than "C:\Program Files (x86)", more probably in other drive or in the directory where Eclipse is extracted)
Eclipse (32 bit) and finally ADT.
I tried it and all works fine.
Do you have a JAVA_HOME variable defined? That might help. On my system I have JAVA_HOME set to
C:\PROGRA~2\Java\jdk1.6.0_24
A little odd perhaps (using the "~" dir instead of the "Program Files" dir, but seems to help with some older scripts that don't expect to see spaces in the path name.

I have thoroughly researched this problem and the posted solutions have not worked for me.
I'm running Windows 8, and the most recent JAVA JDK (64 bit) and Android Studio versions.
[System specs: new XPS 13, core i5, 8GB RAM, SSD]
The exact error is:
Failed to load JVM DLL C:\Program Files\Java\jdk1.8.0_45\jre\bin\client\jvm.dll
If you already have a 64-bit JDK installed, define a JAVA_HOME variable in ... Environment Variables
-- Verification --
java -version
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b15)..
-- Things I've tried --
Uninstall java and AS, reboot, install 64 bit java jdk, verify installation, reboot, install AS, set JAVA_HOME variable
YES, the viable is an Environment variable and not a User variable
I have added the /bin/ directory to the "path" environment variable
I have reversed the slashes in the environment variable paths as per one solution stated
Followed the uninstall/reinstall process stated above, but with a 32bit jdk instead (with the correct environment variable paths)
Done the whole process over (uninstalling, rebooting after installs, etc.) but with older JDKs
I have tried running studio.exe with 32 bit JDK installed, and studio64.exe with the 64 bit JDK installed
I feel like I've tried everything. I HAD to have screwed up somewhere along the line. Any idea?
Try running android studio as Administrator. That worked for me. Try installing a different version of Android Studio.
This worked for me...
Try running studio64.exe instead of studio.exe.
I had to install vcruntime140_1.dll via https://learn.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist?view=msvc-170 to solve the this issue. I used process monitor to see that it was missing.
Tried everything nothing worked. Restarted my laptop, Android Studio works perfectly.
I installed Microsoft Visual C++ X86 or X64 from here and AS started up fine.
you said you have added /bin/ directory to the "path" environment variable, if you are putting C:\Program Files\Java\jdk1.8.0_45\jre\bin .that is wrong it should be C:\Program Files\Java\jdk1.8.0_45\jre\bin\client to path system variable and you put it as first item.
I checked my java installation path. I found jvm.dll is located at C:\Program Files\Java\jdk1.8.0_45\jre\bin\server please check yours.
see the screen shot.
I got it working. I uninstalled everything again. Reinstalled the 64 bit jdk, remade the environment variable, rebooted, reinstalled Android Studio and it still was not working.
I downloaded the 32 bit JDK just got giggles and installed it. I did not uninstall the 64 bit java... I pointed the environment variable to the 32 bit JDK directory and tried to launch Androd studio with the 32 bit .exe (not studio64.exe), and it worked.
I guess I'll have to live without 64 bit.
Thanks for the help, everyone.
Trying to open Eclipse after a couple of months and get this error:
So I checked that folder to see if it existed, and it did:
I checked my PATH Was correct and it was also correct:
When this error first occurred I had 3 Java installations. JRE 7 Update 10, JDK 7 Update 7 32bit and 64 bit.
I uninstall ALL and restarted my machine. Eclipse then stated, as expected that I needed a JRE or a JDK. So I downloaded and installed the latest JDK and now I get this error, despite everything appearing to be correct.
Any ideas?
As requested in the comments.
Your eclipse version is searching for the x86 version of the jdk (You probably set this value when eclipse started). You should check if your eclipse is a 64 bit version if not, switch to a 64bits jvm.
the problem lies with compatibility issue of jdd 6 with eclipse.I tried jdk 7 and it worked perfectly.Here is a link for jdk 7 downloading
http://download.cnet.com/Java-Development-Kit-64-Bit/3000-2218_4-75317068.html
The problem is with the Eclipse version. I faced the exact same problem, I was using Eclipse helios. I switched to Eclipse Kepler 64 bit and it is now working perfectly on my system. Even if the eclipse is 64 bit, some versions may not be compatible with other softwares using the same Java path (Eg: Oracle BI Publisher). Make sure to use the version compatible with others.
FIX for :: jvm.dll file missing issue while you open eclipse
This issue appears because of (64 or 32 bit) version conflict/mismatch happens between
installed OS,
Java(JDK)version and
eclipse version.
I got this issue and fixed it in this way.by adding the below argument (64 bit Java(JDK) path) in eclipse.ini.
-vm
C:\Program Files\Java\jdk1.8.0_144\bin
My environment,details below
Mine is windows-7 64bit OS,
Java(JDK) 64 bit (so path specified in eclipse.ini)
Eclipse 64 bit(never confuse the eclipse version as 32 bit by seeing the win32.x86, see the later _64) i.e I use eclipse version below.
org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.500.v20170511-1520
You can see your eclipse version in eclipse.ini file.
Note:
I have another Eclipse (plugin tool) installed in my machine, which had the same issue, was expecting 32 bit Java(JDK), After I fixed the issue by setting the path for 32bit Java1.8 in environment variables, the primary eclipse stopped working.
So I set 64bit Java1.8 path in eclipse.ini.
Now both eclipse.exe and my plugintool eclipse working fine.
Thanks,

Here we fristly check the ur path. when ur path is correctly. Then after u will move the given location (their checking jvm.dll file will be presented or not).
that type problem came max to max 64-bit systems.
Here main focus on path. when u set path then after retsart the system.
This happend to me yesterday and fortunately I found this post.
I was working on eclipse and tried to compile a class using the command line in paralell. I noticed that the javac command wasn't on the Path environment variable so I added.
Afterwards, I closed Eclipse and when I tried restarting the IDE I found the "Failed to load JNI shared Library" error.
I opened back the environment variable dialog box and pointed the java bin path to a compatible version of java (Same bit version on both, eclipse and jdk).
Finally I was able to start eclipse again.
After a couple of months with no Android development, I ran the SDK Manager yesterday, and upgraded from r16 to r18. After that upgrade, everything stopped working. I downloaded a fresh copy of the SDK tools from Google. The Windows installer complains there's no Java installed (the solution here , which used to work before, doesn't work).
I downloaded the ZIP file instead and put it in the right place. Running SDK Manager.EXE does nothing (it just returns immediately to the command prompt). Running tools\android.bat displays an error complaining "Failed to convert path to a short DOS path: c:\windows\system32\java.exe", and then suggests I install Java.
I'm running Windows 7 64-bit, with Java 1.7 (64 bit) properly installed (Eclipse runs well, the Android tools r16 ran very well until yesterday). c:\windows\system32\java.exe exists and works as it should.
What am I doing wrong?
UPDATE: I found an old r16 setup around. I installed it and everything went back to normal.
I put this one aside for a while, but now I had to get it back running. I didn't want to install a 32-bit Java VM alongside the 64 bit one I have.
I found the culprit. in android_sdk\tools\lib there's a batch-file called find_java.bat. It calls find_java.exe -s to find a list of potential Java locations. Running the exe file like this returns the error I've been seeing:
Failed to convert path to short DOS path: c:\windows\system32\java.exe
-s stands for short. Running it without the -s causes find_java.exe to work, causing find_java.bat to work, causing everything else to work. So the fix was to edit find_java.bat, and remove the -s .
I honestly don't know what Google is thinking.
My fix was to remove /bin from my JAVA_HOME, as in C:\Java\jdk1.6.0_26\bin --> C:\Java\jdk1.6.0_26\
I'm running 64bit java on W7.

This is just a guess, but I advise you to install JDK 6. It is said in the SDK requirements that you have to use it. I remember that I installed JDK 7 and I had some kind of trouble with it too.
Also it is safer to use the 32-bit version.
You need to also update the Eclipse plugins via Help > Install New Software.
I was able to fix same like problem by adding the jdk path to PATH variable in environment variables.
This problem was asked many times, but none of solutions doesnt help me.
I am using Windows 7 SP1 (x64), JDK 1.7.0_03 (x86), JRE 7 (x86) and Android SDK Tools r16.
When I install Android SDK Tools it says -
Java SE Development Kit (JDK) version 1.7 has been found
But after install SDK Manager closes instantly. android.bat and find_java.bat say -
WARNING: Java not found in your path.
I have tried set enviroment variables JAVA_HOME, PATH manually but this doesnt help. Searching solution many hours, setting variables, reinstalling java / sdk - nothing helps.
Thanks in advance.
Install the x86 version, not the 64 bit version.
Android requires Java 1.5 or 1.6.
I haven't tested this, but I have seen posts about Android working with 1.7 as long as you also have 1.6 installed. Although this requires having two versions of java installed, and I am not sure it's worth it.
maybe you are using JRE, not JDK.
You can check which java you are using with: where java
I just set a Environment Variable named JAVA_HOME with the value: C:\Program Files\Java\jdk1.7.0_05\
The problem is solved and sdk works properly.
Well, I was facing the same problem, I found that the error might be a resolved by doing the following.
Download Android SDK, try to install, you get a java error (if you don't have it)
Typically you go download java, install and hit retry - but fail.
Adding JAVA_HOME didn't help, so I rebooted the pc and tried again.
Success, I don't know if it's the reboot after installing JAVA, or reboot after adding JAVA_HOME that solved the problem. One of them did the trick.
My recommendation is :
1. Install JAVA (in my case 1.7 x64), reboot.
2. Install android sdk, if it fails, add JAVA_HOME as explained above somewhere, reboot.
3. Install the sdk.
I know that this may be outdated, but someone would probably find it useful. I had this problem myself, easiest(maybe dirty) solution I came up with is to change the default location when installing android studio.
Something like this :
C:\Program files\Java\jdk-xxx\
to =>
C:\Program files(x86)\Java\jkd-xxx\
Installer is searching in x86 Program files folder probably for a 32bit version, but its working perfectly for me this way :)
If you believe you have JDK installed and it was not properly recognized, set SDK Location on Eclipse (Windows > Preference). You can open/Update SDK Manager thru Eclipse.
Work fine in my Windows 7 SP1 (x64), JDK 1.7.0_03 (x64), JRE 7 (x64) and Android SDK Tools r17.
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
