React Native: JAVA_HOME is not set and no 'java' command could be found in your PATH

I've followed step by step the official Getting Started. I started from a clean linux install and installed everything required as per the "Building Projects with Native Code" tab. I have also read the troubleshooting section. I've already created the project using the terminal.
This is the error when I run react-native run-android:
Starting JS server...
Building and installing the app on the device (cd android && ./gradlew installDebug)...
ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.
Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:
https://facebook.github.io/react-native/docs/android-setup.html
It does not find JAVA_HOME because the latest versions of Android Studio don't require Java to be installed in the system. Instead an internal JRE is used.
Duplicate disclaimer: I've already read this question. This is not what I want. I know how to set the Java home. I just want to run the react project WITHOUT having to install a separate Java.
Questions:
How could I find the internal Java inside the Android Studio folder so that I could point JAVA_HOME to it?
If not possible, could I open and run the project inside the android folder with Android Studio? How would I refresh this project after modifying the React JavaScript code in the parent folder?

Windows 10:
Android Studio -> File -> Other Settings -> Default Project Structure... -> JDK location:
copy string is shown, such as:
C:\Program Files\Android\Android Studio\jre
In the file locator directory window, right-click on "This PC" ->
Properties -> Advanced System Settings -> Environment Variables... -> System Variables
click on the New... button under System Variables, then type and paste respectively:
.......Variable name: JAVA_HOME
.......Variable value: C:\Program Files\Android\Android Studio\jre
and hit the OK buttons to close out.
Some installations may also require JRE_HOME to be set in the same way.
To check, open a NEW black console window, then type echo %JAVA_HOME%. You should get back the full path you typed into the system variable. Windows 10 supports spaces in the filename paths for system variables very well and does not need ~tilde eliding.

I'll answer my own questions and sponfeed my fellow linux users:
1- To point JAVA_HOME to the JRE included with Android Studio first locate the Android Studio installation folder, then find the /jre directory. That directory's full path is what you need to set JAVA_PATH to (thanks to #TentenPonce for his answer).
On linux, you can set JAVA_HOME by adding this line to your .bashrc or .bash_profile files:
export JAVA_HOME=<Your Android Studio path here>/jre
This file (one or the other) is the same as the one you added ANDROID_HOME to if you were following the React Native Getting Started for Linux. Both are hidden by default and can be found in your home directory. After adding the line you need to reload the terminal so that it can pick up the new environment variable. So type:
source $HOME/.bash_profile
or
source $HOME/.bashrc
and now you can run react-native run-android in that same terminal. Another option is to restart the OS. Other terminals might work differently.
NOTE: for the project to actually run, you need to start an Android emulator in advance, or have a real device connected. The easiest way is to open an already existing Android Studio project and launch the emulator from there, then close Android Studio.
2- Since what react-native run-android appears to do is just this:
cd android && ./gradlew installDebug
You can actually open the nested android project with Android Studio and run it manually. JS changes can be reloaded if you enable live reload in the emulator. Type CTRL + M (CMD + M on MacOS) and select the "Enable live reload" option in the menu that appears (Kudos to #BKO for his answer)

I think the right way to find the internal Java used by the Android Studio is to
Open Android Studio
Go to File->Other Settings->Default Project Structure/JDK Location:
and copy what ever string is specified there
This will not require memorising the folder or searching for java and also these steps wil take of any future changes to the java location by the Android Studio team changes I suppose

I'm using Ubuntu 20 on my machine, I have got the same problem the thing that worked for me was:
sudo apt-get install default-jre
you can verify that if the installation was successful or not by:
java --version
you are gonna see something like this in your terminal
openjdk 11.0.12 2021-07-20
OpenJDK Runtime Environment (build 11.0.12+7-Ubuntu-0ubuntu3)
OpenJDK 64-Bit Server VM (build 11.0.12+7-Ubuntu-0ubuntu3, mixed mode, sharing)

It is located on the Android Studio folder itself, on where you installed it.

Please add the JAVA_HOME in the System variable no in the user variable
Create the Variable name as JAVA_HOME
Please use these format in the value box --> C:\Program Files\Java\jdk(version) what you have or downloaded.

I fixed this issue by installing jre, I have jdk already installed but jre was not installed.

For those still not able to set JAVA_HOME from Android Studio installation, for me the path was actually not in C:\...\Android Studio\jre
but rather in the ...\Android Studio\jre\jre.
Don't ask me why though.
Environment variables jre location snippet

For ubuntu 16.0+
You can find the jre folder in android studio on this path /snap/android-studio/current/android-studio/jre
add the following line in your .bashrc or .bash_profile
export JAVA_HOME=/snap/android-studio/current/android-studio/jre
type
sudo nano $HOME/.bashrc
or
sudo nano $HOME/.bash_profile
after this execute the following line to in your terminal where you are executing the npx react-native run-android to reload the terminal with the new changes
source $HOME/.bashrc
or
source $HOME/.bash_profile

All I did is go to my project directory from the cmd (command prompt) I typed java -version.it told me what version it was looking for. so I Installed that version and I changed the path to were the jdk of that version was located .

apparently the system variables were not in sync with the user
variables
run as admin on command prompt and set the variable
i also saw some tips to close the node window and the vscode terminal for
the variable to take effect
tip from this site
https://confluence.atlassian.com/doc/setting-the-java_home-variable-in-windows-8895.html
setx -m JAVA_HOME "C:\Progra~1\Java\jdk1.8.0_XX"
and then
echo %JAVA_HOME%

For fish users:
Open ~/.config/fish/config.fish;
Include line set JAVA_HOME /home/ronald/Documents/android-studio/jre and set PATH $PATH $JAVA_HOME;
Re-open fish terminal.
Welcome :)

After adding the environmental variable , please restart the editor. It may save your ton of time.

Make sure you have java installed
your path is wrong
do this:
export | grep JAVA
THE RESULT: what java home is set to
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home
follow the path to see if the directories are correct
i did this in my terminal:
open /Library
then i went to /Java/JavaVirturalMachines
turns out I had the wrong "jdk1.8.0_202.jdk" folder, there was another number...
4. you can use this command to set java_home
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home

I ran this in the command prompt(have windows 7 os):
JAVA_HOME=C:\Program Files\Android\Android Studio\jre
where what its = to is the path to that jre folder, so anyone's can be different.

what I did to solve this on windows was to go to the environment variables and set the variable name to JAVA_HOME and then set the variable value to C:\Program Files\OpenJDK\openjdk-8u312-b07
then I set the path to C:\Program Files\OpenJDK\openjdk-8u312-b07\bin

From Android Studio, go to File, Settings, "Build, Execution, Deployment", Build Tools, Gradle. You should see the path to your JDK there, as visible in the screenshot (tested on Android Studio version 2020.3.1). Set an environment variable called JAVA_HOME containing that path (just google "set an environment variable" and followed by your Operating System name).

for those who are new to react native development
please set JAVA_HOME like this
instead of
C:\Program Files\Java\jdk1.8.0_301\bin
just remove "\bin" from path
C:\Program Files\Java\jdk1.8.0_301 after removing \bin

Guys after fight a lot to find the solution, including pass for many of that articles. I just realized that when you extract the Android SDK it doesn't come inside the folder cmdline-tools/latest and doesn't matter the place that I put the folder, opt/Androd_SDK, $HOME/Android_SDK the sequence of the error were the same. Until I got this error running:
➜ bin ./sdkmanager -version
Error: Could not determine SDK root.
Error: Either specify it explicitly with --sdk_root= or move this package into its expected location: /cmdline-tools/latest/
So, basic the solution was add the content of the SDK zip inside of the folders cmdline-tools/latest.
Once you do this, SDK and all the commands will work normally. Just don't forget to finish the configuration, like create the environment of the Android SDK, JAVA and so on.
An awesome article is that one:
https://medium.com/#khairold/setting-up-react-native-on-linux-without-android-studio-a65f3e011bbb
;)

if someone still facing similar issue and looking for an answer for the same? I would like to share the solution which worked for me. And by the way I haven't installed JAVA JDK/SDK in order to resolve the issue.
I am using Visual Studio code to develop react-native apps (using nox player for android app testing), I ran into the similar issue:
Issue:
$
› Building app...
$
ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.
$
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.
C:\Users...\android\gradlew.bat exited with non-zero code: 1
Resolution: In package.json file I have changed "main": "index.js" to "main": "node_modules/expo/AppEntry.js" it worked for me.
It would be great if this solution helps anyone, let me know for any additional information.

Make sure you have installed the following:
Java
JDK
JRE

If you use Ubuntu, maybe its helpful this tutorial. You have solution for how to solve error ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH..
There are many solutions found for Windows or Mac OS on internet to resolve this error. I'm using Ubuntu 22.10 kinetic
Solution:
Go to your Android Studio folder, find folder named jbr, copy all content folder, and if you don't have, create a folder named jre and copy in jre folder, all contents from jbr folder. Case close. Error solved.

Android Studio 1.5.1 Setup

Hi guys I'm trying to install Android Studio 1.5.1 by following Standard setup phases but having the following error. I've JDK version 1.7:

It looks as if it failed to stop the adb service at one point during installation. I would simply try running the installation as second time, and then it should skim over the already-installed components and install the missing one.
Similar post on stackoverflow: Error: Stopping ADB Server Failed (Code -1) {Installing API's - Android SDK}

you can try this step.
set the path of jdk using following step.
property of my computer
click on advanced system setting
click on environment variable
find path variable on system variable
set below path on path variable
C:\Program Files\Java\jdk1.8.0_05\bin
then check it on cmd
by entering command javac.
its helpfull for you.

Gradle in Android Studio giving error Project sync failed

I am new to Android Studio.I installed Android Studio-1.2.1.1 and i have jdk1.7.0_40 installed.I am facing problem with gradle build.
For reference you can check gradle issue
I am getting following error in messages
Error:The newly created daemon process has a different context than expected.
Java home is different.
Expecting: 'C:\Program Files\Java\jdk1.7.0_40' but was: 'C:\Program Files\Java\jdk1.7.0_40\jre'.
Please configure the JDK to match the expected one.
Open JDK Settings
All i understood is gradle is using JRE and Android Studio is using JDK and due to that two JAVA_HOME's are different and giving errors.
I tried downloading gradle 2.3 and changed gradle path in android studio to this file,still same problem.

This is a very late answer but I see that a common suggestion is to remove all other jdk's and this is not always the best idea. You might need older jdk's for different projects. You can go into the gradle.properties file for the project and enter the following line (varied based on your version):
org.gradle.java.home=C:/Java/jdk1.8.0_111
If you are using a different jdk just point to a different directory.

Replace this
C:\Program Files\Java\jdk1.7.0_40\jre
with
C:\Program Files\Java\jdk1.7.0_40
inside your JAVA_HOME variable

EDIT:
I fixed this issue by uninstalling all the jdk installation & updates
then reinstall only one jdk and assure its env. variables
I do not have a solution but I have the same problem
it happens as the android studio opens from java_home/jre thence all JVMs that will fork next will come from this path, while your system varible tells Gradle to get his java.exe from JAVA_HOME
I tried to make gradle read from jre but it falied also i tried to make android studio open from java_home/bin but it falid also

For those who are on OS X El Capitan (v10.10) and end up with the above error message.
In my case there was nothing wrong with Gradle, simply my Java 1.8 was "too new" for Android Studio 1.5 so I had to install older 1.7.
I downloaded it from
http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
(jdk-7u79-macosx-x64.dmg)
After all I had to just update JDK location in the project structure

I already had java jdk 7u17 and I also had got same error as FaizAli.
I try to search and done a lot of changes but not success!
Then, I downloaded jdk 7u80 at this link and installed this jdk.
After that those error gone.

I solved it by going to Project Structure then unchecking use embedded JDK and then setting the path to C:\Program Files\Java\jdk1.8.0_121

What I found out in my case is that the SDK my project pointed to "broke" and I had to fix its "JDK home path":

This is 2019.
For anyone experiencing this issue...
The first thing is to make sure that you correctly set your environment variables as per this instruction: https://www.mkyong.com/java/how-to-set-java_home-on-windows-10/
Which means you should be able to type javac -version and java -version and get the version number inside your Home directory.
Once you can confirm this, then go to the Project Structure inside, the SDK Location > JDK Location select Use JAVA_HOME environment variable.
This was what I did and it worked.

Solved this by going to
File -> Project Structure -> SDK Location
and under JDK Location, update with Gradle SDK location.

This happens because Android is using embedded ( JRE ) which is selected as recommended and at same time Android Studio detects JDK Home_Path (Environmental Variable ) and due to that two JAVA Path are different there is the conflict so it give you Error :
If You remove java_home path or Environmental variable you will get this error:
CreateProcess error=2, The system cannot find the file specified [Android studio
For Android Studio, the solution is to go to File> Other Setting > Default Project Structure> Uncheck the checkbox
and browse and set JDK path

FINAL SOLUTION
Finally I re-installed JDK and Android SDK and now everything works even it is still mystery to me.

I had the same issue and solved it by setting the following environment variables:
%JAVA_HOME% points to the root of your java installation (not the bin directory). In my computer it is: C:\Program Files\Java\jdk1.8.0. To test that it is configured correctly, open a new terminal and type javac. It should run the java compiler and shouldn't complain that it doesn't know the command. Please note that environment variables are only set when opening a new terminal (at least on windows) so every time you change something you have to open a new terminal.
%ANT_HOME% point to the root of where you've installed Apache ant. In my computer it is: C:\Users\User\apache-ant-1.9.3. Test it by running the ant command. It shouldn't complain that the ant command is unknown to your machine. Remember to open a new terminal after setting the path and then try running ant.
%ANDROID_HOME% points to where you have installed your android SDK. For example: C:\Users\User\android\sdk. Then try typing emulator to make sure it is installed correctly.
When all of these variables are set, you can use them in the PATH environment variable :
%PATH% contains the following entries: %ANT_HOME%\bin;%ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools;%JAVA_HOME%\bin
On windows 8 you can configure path and variables by right clicking on the start button, choosing system, and then advanced system settings and clicking on environment variables button. Remember to define the above environment variables above PATH. I defined everything in the user variables and it works just fine.

-Possible solution for those who encounter this error
I had this error and it did relate to the path variables. I thought I had everything set correctly, but I was missing a portion.
First check by typing the command android into command line. If the SDK isn't opened you have not set the variables and/or path correctly.
You should have 3 (or 4 if you have separate android ones) variables.
ANT_HOME, JAVA_HOME and ANDROID_HOME
ANDROID_HOME should point to the sdk. If you (like I did) downloaded the bundle which includes eclipse, you need to have this variable point to the sdk folder inside the android bundle folder, not the android bundle folder itself (eg. C:\Dev\adt-bundle-windows\sdk)
You need to add %ANDROID_HOME%\tools and %ANDROID_HOME%\platform-tools to your path. Along with the link to the ANT bin folder and jdk bin.
I strongly urge you to triple check that all variables are correctly set AND that all four parts are added to the path.

Please Refer the Question
An error occurred while listing Android targets
and the Link
developer.android.com/tools/devices/managing-avds-cmdline.html
Most probably the path variable pointing to this android was wrong.
I had used %ANDROID_HOME% as variable and scaled the same to path variables %ANDROID_HOME%\SDK\TOOLS. This method doesn't work. Experimentally resolved by directly pointing to the Tools and Platform Tools.
Just based on what I did and it worked for me. Hope You get the Issue resolved.

I had the same issue with version 3.5.0.
The problem is, that the error message from the script check_reqs located in C:\Users\{yourUserName}\.cordova\lib\android\cordova\3.5.0\bin, is not forwarded correctly.
I run the mentioned script manually and got the following error message:
[Error: Please install Android target 19 (the Android newest SDK). Make sure you have the latest Android tools installed as well. Run "android" from your command-line to install/update any missing SDKs or tools.]
So basically to solve this issue you have to install the latest Android SDK.

This link http://spring.io/guides/gs/android/ + running cmd as an administrator solved that issue for me.
This confirms Michael Brooks' assumption that this issue has to do with permissions settings on the Windows OS. https://github.com/phonegap/phonegap-cli/issues/77

Android Studio installation on Windows 7 fails, no JDK found

I downloaded Android Studio and attempted to launch the program.
This is running on Windows 7 64-bit with Java 1.7. During the installation, my Java 1.7 is detected, and the rest of the installation goes through just fine. However, when attempting to launch the application from the desktop icon, nothing happens. Looking at the task manager, a new process from the CMD is loaded. This is because it's attempting to run the batch file studio.bat.
When I execute via CMD, I get the following error:
ERROR: cannot start Android Studio. No JDK found. Please validate
either ANDROID_STUDIO_JDK or JDK_HOME or JAVA_HOME points to valid
JDK installation. ECHO is off. Press any key to continue . . .
I've attempted to open the idea properties file to see if there was something I could configure for this ANDROID_STUDIO_JDK or something like that. However, I found nothing. I hope some of you can let me know if you were able to install this or if you are having problems as well.

Adding a system variable JDK_HOME with value c:\Program Files\Java\jdk1.7.0_21\ worked for me. The latest Java release can be downloaded here.
Additionally, make sure the variable JAVA_HOME is also set with the above location.

OK, I figured out how fix this nasty bug.
Before you start
Go to your Android Studio installation folder and locate the bin folder. Inside the bin folder, you will find studio.bat. Execute the file, and it'll show the error. If it is about the Java path then follow the tip 1.
Tip 1
When you set the path JAVA_HOME, etc., make sure not to include bin at the end of the path. This solved the issue for me.
JAVA_HOME => C:\Program Files\Java\jdk1.7.0_21
path => C:\Program Files\Java\jdk1.7.0_21\bin
It works fine with JDK 1.7 (I tried with 32 bit).
If you do so, you can see the initial screen as below.
Tip 2
Are you getting the below error message?
Your Android SDK is out of date or is missing templates. Please ensure
you are using SDK version 22 or later.
This error probably occurs, because you have reference to your older SDK (that you downloaded with Eclipse) in your path variable. Go to Environment variables and remove any reference to the old SDK folder and point it to new SDK folder that is found inside the Android Studio installation folder.
Save and restart Studio, things should work as expected now.
Tip 3
If you hate messing around with the path variable as given above by removing old references, simply follow the following steps to refer to new SDK path that comes with Studio.
*Project Defaults* -> *Project Structure* -> Click "New" -> Select "Android SDK" -> Select the SDK folder inside the studio installation.

With the last update of Android Studio, I have two versions of the IDE's launcher
One is called studio.exe and the other studio64.exe they are both on:
C:\Users\myUserName\AppData\Local\Android\android-studio\bin
You have to launch the one that matches your Java version 64 or 32 bit

I had the same issue. I got resolved setting up correctly the environment variables in windows, for instance:
JAVA_HOME -> C:\Program Files\Java\jdk1.6.0_45
path -> C:\Program Files\Java\jdk1.6.0_45\bin

I've tried so many of the answers here but none of them works, so I decided to mix some of the answers here and I am successful!
Step 1: Go to the system properties by right-clicking on My Computer or by pressing windows button on typing This PC and right clicking on it and selecting Properties.
Step 2: Click the advanced system settings or Environment Variables
Step 3: Take note that there are 2 different variable. What you need to create is system variables not user variables, when you clicked new type the following
Variable name: JAVA_HOME
Variable value: C:\Program Files\Java\jdk1.8.0_25\ (Note: Please check if the path is right, sometimes it is C:\Program Files (x86)\Java\jdk1.8.0_25)
Step 4: Run the android studio, no need to restart.
Note:
*C:\Program Files\Java\jdk1.8.0_25\ depends entirely on the installation path of your JDK not JRE so don't be confused if you see something like the picture below. Just enter the location of your jdk, in my case it is C:\Program Files\Java\jdk1.8.0_25\.
*Do not include the bin folder when you enter the Variable value.
Edit: For Windows 8 and 10 Users: Try to run C:\Program Files\Android\Android Studio\bin\studio.exe instead of C:\Program Files\Android\Android Studio\binstudio64.exe

I had the same issue. I am having 64-bit windows 8. I downloaded the android studio which worked on a 32-bit machine but not on my 64-bit.
The solution for me was pretty simple. I navigated to
C:\Program Files (x86)\Android\android-studio\bin
there I saw 2 exe files studio.exe and studio64.exe. Normally my start menu was pointing to studio64.exe which always kept on giving me "The environmental variable JDK_HOME does not point to valid JVM". So then I clicked studio.exe and it worked :)
I hope this may help someone facing the same problem as me

The path for the latest JDK. It worked very well.

If you are getting message "Your Android SDK is out of date…" — click "Configure" —> "Project Defaults" —> "Project Structure", pick "SDKs" —> "Android SDK" and in a "Build Target" choose "Android 4.2.2". Click "OK". Now it should work fine.

I got the problem that the installation stopped by the "$(^name) has stopped working" error. I have installed the Java SE Development kit already, and also set both SDK_HOME and JAVA_HOME that point to "C:\Program Files\Java\jdk1.7.0_21"
My laptop installed with Windows 7 64 bits
So I tried to install the 32-bit version of the Java SE Development kit, and set my JAVA_HOME to "C:\Program Files (x86)\Java\jdk1.7.0_21", restart and the installation worked OK.

This problem has been fixed in Android Studio v0.1.1, so just update Android Studio and it should work.

Sometimes you can resolve this type of issue by setting environment variables so the process looks for the JDK in the right spot.
Another approach is to figure out where the process is looking, then put your JDK there.
I've had lots of success using Process Monitor from Sysinternals:
Start -> Run -> procmon
Go to the Filter menu, then select Filter...
Set Event Class is File System then Include
Add, then OK
This will filter down to all the file system operations taking place on your machine.
You could try filtering based on the result of the File System operation:
Right click on the Result column, then Exclude 'SUCCESS'
You can also quite easily filter based on the process name, either from the Filter... menu option or by right clicking on the Process Name column and selecting Include 'process.exe'.
Once you find the file system operation that's failing, the Path column will tell you where to put your JDK.
I've found this to be very empowering. Especially compared to the frustrating process of changing environment variables by trial and error.

My issue was caused because I have an & character in my Windows user name, so when installed in the default path I was getting the following error after running bin/studio.bat
|
v notice broken path
The system cannot find the file C:\Users\Daniel \studio64.exe.vmoptions.
Exception in thread "main" java.lang.NoClassDefFoundError: com/intellij/idea/Main

Could not find the main class: com.intellij.idea.Main. Program will exit.
So I uninstalled and reinstalled it to program files and it launches fine now.

I couldn't get this to work no matter which environment variables I set. So I simply put a copy of the JDK into my Android Studio installation folder.
Copy the contents of the JDK installation (for example, C:\Program Files (x86)\Java\jdk1.7.0_21)
Paste them into the installation directory of the Android Studio (for example, C:\Program Files (x86)\Android\android-studio)
I somewhat assumed that the issue was caused by having the x64 version of the JDK installed. But what was especially confusing was the fact that I could start Android Studio just fine when I started the studio.bat as an Administrator (even though the environment variables were set for my personal user account).
studio.bat will look for several valid options when determining which JDK to use.
:: Locate a JDK installation directory which will be used to run the IDE.
:: Try (in order): ANDROID_STUDIO_JDK, ..\jre, JDK_HOME, JAVA_HOME.
As explained above, I picked the ..\jre option.

Today I found another situation when this problem occures - when you have several JDK, defined in JAVA_PATH. I have:
JAVA_HOME = C:\JAVA\JDK\jdk1.6.0_38;C:\JAVA\JDK\jdk1.7.0_10
So I received this problem with Android Studio setup
But when I've removed one of JDK - problem has been solved:
JAVA_HOME = C:\JAVA\JDK\jdk1.7.0_10
Installation wisard found my jdk and i had a nice night to study studio.
But unfortunatelly even installed studio doesn't work with several jdk.
Does anybody know how to fix it?
I hope I've helped someone

Add JAVA_HOME and JDK_HOME system environment variables.
Right-click
android studio (the 64 version if that's your OS and JDK) and go to
compatibility tab and set "Run as administrator" to true.
Run android studio and high-five me virtually when it works.
If that fails, try "where java" in cmd.exe. If it lists c:\system32\java.exe first, then rename the file and try again.

Windows 64 bit, JDK 64 bit (Solution that worked for me)
Tried all the above solutions, and None of them worked, I have been trying to solve it for the past few days and now I did it successfully. For me the problem was when I first installed Android Studio my JDK version was 1.7, then after installing I updated the JDK to 1.8, then I removed the old JDK folder and everything was messed up, even uninstalling and reinstalling android studio randomly didn't solve the issue.
Below is the solution that worked for me
Uninstall Android Studio.
clean temp files and android studio C:\Users\Username.AndroidStudio1.5
Uninstall JDK.
Now without JDK try to install Android Studio and now it will show the message that it can't find any JDK. Stop installation
Install JDK 1.7 or 1.8 (Set JAVA_HOME, JDK_HOME, path Environment variables as explained by everybody above)
Install Android Studio.
Done. Enjoy and happy coding.

MAKE SURE YOU RESTART ANDROID STUDIO
Even though I should know better and swear I did, make sure you restart studio after making these changes as it clearly does not check them on every build (which to me makes sense that system/user variables should only be read once on startup)
Anyway, yea... Make sure you restart after you make these changes.
Path = to the bin folder in the jdk folder (path already exists)
JAVA_HOME = to the jdk folder

Install the latest JDK in your system from JDK 7 and JRE 7 Installation Guide.
JAVA_HOME -> C:\Program Files\Java\jdk1.7.0_4
path -> C:\Program Files\Java\jdk1.7.0_4\bin

If setting the JAVA_HOME variable doesn't work for you, set:
STUDIO_JDK=C:\Progra~1\Java\jdk1.8.0_172
Where the path points to your JDK installation
This is the only thing which works for me in Windows 32bit with Android 10 and up.

In my experience, I was unable (even after adding JDK_HOME) to launch Studio via either the shortcut or studio.exe itself. I had to first run bin/studio.bat (mentioned in the original question).
After the first successful launch, I'm able to start it with the shortcut.

If you have a 64 bit windows OS, pointing the JAVA_HOME system variable to
C:\Program Files (x86)\Java\jdk1.7.0_21
Will work when
C:\Program Files\Java\jdk1.7.0_21
fails to work.

You need 1.7 JDK installed on your system. Add a system variable with:
name: ANDROID_STUDIO_JDK
path: your JDK path (for example, C:\Program Files\Java\jdk1.7.0_21)
See more at FIX: Android Studio - Installation Issues on Windows 7 | ERROR: cannot start Android Studio. No JDK found.

TRY TO INSTALL 32BIT JDK
if you have jdk installed and had set up the System Varibles such as JAVA_HOME or JDK_HOME
and tried click back and then next ,you might have installed the 64bit JDK,just download the 32bit jdk and install it.

I downloaded the latest jdk version
JAVA_HOME to C:\Program Files\Java\jdk1.8.0_11\bin
Set the PATH to C:\Program Files\Java\jdk1.8.0_11\bin
I restarted the STUDIO and it worked.

On Windows 10, restarting the installer and running as admin worked for me.

To complete this stack of possible solutions: For me the problem was, that I did not execute the Android-Studio-Setup as administrator. Running it as administrator then made me able to install Android-Studio.

For me, the problem was that I had changed the GC vm arg to -XX:+UseParallelGC in the C:\Users\<username>\.AndroidStudio2.1\studio64.exe.vmoptions file. That's what I use in Eclipse and I was trying various things to get AndroidStudio half way as efficent as Eclipse. I restored the GC to -XX:+UseConcMarkSweepGC.

The answer to the original question is that, might be you are opening android studio from 32 bit shortcut icon of android studio, try to open from icon "studio64" located under .../bin/ where android studio setup is install.

In case you had it running but Now it doesn't Launch.
I deleted the C:\Users\<NAME>\.AndroidStudio<version>\ folder and it worked.
