Android studio doesn't start on windows 10 - android

I bought a new laptop and tried to install Android Studio, but It doesn't start.
I set the right path of "JDK_HOME" and "JAVA_Home" in the environment cariables.
Checked if the Java.exe doesn't exist in C:\Windows\System32
When trying to start Android Studio it shows the process in the Task Manager and disappears instantly.
My JDK Version is 1.8.0_121.

You don't need JDK_HOME and JAVA_HOME
delete one of them should solve your problem. android studio might got duplicated configuration.
If problem remains remove android studio and reinstall it.

Download Android Studio ide Only

There is a chance my question is related to other questions.but i want to download Android studio ide only. Because I already have Android studio. I have an error with running Android studio like. JAVA_HOME DOESN'T HAVE VALID JVM INSTALLATION SO I want Try uninstall and reinstall Android Studio. I Uninstalled but I don't have Android Studio installer because I copyed Android Studio from another laptop. My another laptop is dead. I don't want to waste my 900 mb internet. Please help me.
You need to set JAVA_HOME variable to run Android Studio .
Steps to set JAVA_HOME variable:
locate your java installation directory.
Open Command Prompt (make sure you Run as administrator so you're able to add a system environment variable).
make sure to replace [JDK PATH] with your java installation directory.
setx -m JAVA_HOME "[JDK PATH]"
restart Android Studio

My Android studio is closing automatically. I have tried setting up JAVA_HOME in environment variables.But it doesn't work at all.Any problem with my SDK or java version?Currently I have both 32bit and 64bit of java JDK 8..But it doesn't work for both.Can someone resolve it soon..I have been trying it for 2 days..
Just uninstall android studio and download the .exe installer file for it here and try reinstalling it, if it doesn't still fix the issue, tell me again, else mark the answer as correct.

Android Studio not Opening after closing it [duplicate]

This question already has answers here:
Android studio isn't opening on Windows
(28 answers)
Closed 1 year ago.
After I close out the Android Studio tab, I am not able to open it again. I am not able to open Android Studio until I uninstall and reinstall the software. Every once in a while, the screen will go gray and I am forced to reinstall again.
I have tried right clicking and selecting 'open', but it doesn't do anything.
I expected Android Studio to open after clicking on it, but it is as though I never installed it at all. It only works until I close the tab.
Update:
I went into my files and clicked on one called 'Studio'. It gave me an error titled Error launching Studio. Here is what it said:
Failed to load JVM DLL C:\Program Files\Android\Android Studio1\jre\jre\bin\server\jvm.dll
If you already have a 32-bit JDK installed, define a JAVA_HOME variable in Computer
> System Properties > System Settings > Environment Variables.
Remove the cache files from user-> appdata-> android studio
On Windows: %USER_HOME%.gradle/caches/
Use your uninstaller to remove all the cache, registry, files, temp then restart install new version of android studio to different location.
I was having a problem with Android Studio a few weeks ago when my antivirus was removing a file needed to launch the app on my device.
I had to re-add the library file that it would keep removing before I caught that it was proudly telling me that it was removing that file to quarantine.
Long story short check that your antivirus is not removing the file.
I was able to resolve the same issue by refer to the solution provided in Android Developer Portal,
Studio doesn't start after upgrade
If Studio doesn't start after an upgrade, the problem may be due to an invalid Android Studio configuration imported from a previous version of Android Studio or an incompatible plugin. As a workaround, try deleting (or renaming, for backup purposes) the directory below, depending on the Android Studio version and operating system, and start Android Studio again. This will reset Android Studio to its default state, with all third-party plugins removed.
For Android Studio 4.1 and later:
Windows: %APPDATA%\Google\AndroidStudio
Example: C:\Users\your_user_name\AppData\Roaming\Google\AndroidStudio4.1
macOS: ~/Library/Application Support/Google/AndroidStudio
Example: ~/Library/Application Support/Google/AndroidStudio4.1
Linux: ~/.config/Google/AndroidStudio and ~/.local/share/Google/AndroidStudio
Example: ~/.config/Google/AndroidStudio4.1 and ~/.local/share/Google/AndroidStudio4.1

Android Studio doesn't launch: Could not find or load main class com.intellij.idea.Main

Being new in Android devopmnet, I have been using Android Studio for development, but suddenly it doesn't work anymore.
The program doesn't launch anymore, and If I execute the studio.bat from Command Prompt, I get the following error:
Error: Could not find or load main class com.intellij.idea.Main
I have seen other posts about Android Studio not launching (e.g. this and this), but neither of them solve my problem. I have set PATH variables for both JAVA_HOME and JDK_HOME correctly to C:\Program Files\Java\jdk1.7.0_07
As I have mentioned, Android Studio used to work and I don't have any idea why it has stopped working. Any clue?
For android studio 1.3.1
go to environment variable and create new variable and give it a name JAVA_HOME and in path use this C:\Progra~1\Java\jdk1.7.0_71.
I hope that can help you.
if you have just used copy paste of exe file it will show this message so go in Program Files\Android\Android Studio\bin and click on exe file.
I had the same issue after updating the Android studio. I was not able to launch it from click on Android Studio icon and after running ./studio.sh it was giving me same error
I follow the below step and solved the problem.
I downloaded the studio and install it in the new directory.
After installation success, copy all the files & folders and paste and replace it into old location where studio was installed.
Having JAVA_HOME set to point latest JDK version (C:\Program Files\Java\jdk1.7.0_79) will make the Android studio work. Make sure the path is correct. Seems that JDK_HOME is not needed.
can refer Installing Android Studio (Not working)
If you have recently uninstalled and reinstalled Android Studio and had previously pinned the Android Studio icon to your Task Bar or Start Menu, it may be that this icon no longer looks for the new installation.
Delete it and re-pin it and all will be fine.
I faced the same issue while launching the studio.exe file. The actual problem was I have downloaded the 64-bit version of Android studio. But my computer supports only 32 bit.
So I downloaded 32-bit version and installed.
Now it is working fine.
Well after searching allover the web, failed to get solution till i decided to reinstall android studio. same folder changed nothing didn't delete anything just reinstalled and boom works as before
This happens when you update Studio and new version is installed and previous one is in process of deletion: at the main time if PC shut down or suddenly crashed due to power cut etc. Then this problem will appear:
could not find main class com/intellij/idea/main
Solution:
Go to this path "C:\Program Files\Android", there you will find two Android Studio Folders.
Find which one is latest: (Latest name wold be "Android Studio1") && (Old version would be Android Studio)
Delete old one(if you don't need it any more) and launch latest exe on this path:
C:\Program Files\Android\Android Studio1\bin
Open the Installer and download it again and you can select delete previous versions to clear confusion.
Open studio64 instead of studio
I found Answer: you just make wrong shortcut(just ctrl+C ctrl+v) for launchfile(exe). You must make shortcut following this method:
Right mouse click and select make shortcut menu.
Please follow the below steps,
Go to My Computer -> Properties -> Advance System Settings
System properties window will appear
Go to Advance tab -> Environment Variables -> New
Add or update JAVA_HOME path as expected.
Optionally you can also add or update JDK_HOME if you have JDK installed in your PC

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.
