I just download the newest Android Studio from the developer site.
After installation I installed Android Studio, then I created new project and after project build completed, I opened my MainActivity.java file to find this error. Please refer to screenshot below:
I also downloaded Android SDK component which is built-in already in Android Studio.
Start Android Studio and invalidate cache File--> Invalidate Cache and Restart.
Rebuild your project. Try clean build. That should do. Faced a similar problem.
Tools -> Android -> Sync Project with Gradle Files
Build -> Rebuild
Incorrect installation of JDK also might cause problems. Please tell what the error is in detail.
You can try this for JDK Installation:-
On some Windows systems, the launcher script does not find where the JDK is installed. If you encounter this problem, you need to set an environment variable indicating the correct location.
Select Start menu > Computer > System Properties > Advanced System Properties. Then open Advanced tab > Environment Variables and add a new system variable JAVA_HOME that points to your JDK folder, for example C:\Program Files\Java\jdk1.8.0_77.
Goto File -> Project Structure on left hand side click on SDK Location there you can find Android SDK Location and JDK Location. So, now locate your JDK path by browsing your JDK installation path. Click OK, Now goto Build -> Rebulid your project.
It's better to check whether the JDK path set in Environment variable by typing java -version in commmand prompt. If it is not set, set the path as DvD said in his post.
Hope this works for you.

I have updated android studio, after that i am getting this error.
Unable to find bundled Java version.
unable to find bundle java version
for solving this error on mac just go to finder>Apllications>Android studio:
right click and click show package contents
open the folder of contents
create a new folder called jre
copy the contents of the jbr folder and paste them into jre folder
delete jbr folder
run flutter doctor your error is solved 😊
Try restarting the Studio, reinstall it or Invalidate Caches from File. I am sure one of it will work. The package could be missing in the update. If it doesn't work, open a issue at here
If Just kidding's answer does not work you can just reinstall Android Studio (don't forget to load the Flutter and Dart plugins) and it should be fine again.
My path to java was broken after updating AS to latest version (2020.3.1) and I had to fix it manually. Your issue seems related. Check your Android Studio -> Preferences -> Build, Execution, Deployment -> Build Tools -> Gradle and see if gradle jdk path is set correctly (to your java installation on your mac).
I've successfully installed JDK and also Android Studio both of 64bit and when I've created a new project, called GreetingApp Gradle Build starts and it shows an error with the title of Gradle GreetingApp project refresh failed
Error:CreateProcess error=2, The system cannot find the file specified and also shows a small message that says Gradle Project sync failed. Basic functionality (e. g. editing, debugging) will not work properly.
How can I solve this?
Check jdk version using this path:
File > Other Settings > Default Project Structure > JDK location
If it is set to 32 bit version, set it to 64 version.
If you don't have a 64-bit JDK then download and install it.
This is for people who are using Canary and are having this issue. I went to:
Files->Other Settings->Default Project Structure.
Change the JDK location: C:\from whatever you have here to: C:\Program Files\Android\Android Studio\jre
i used my old path from Android Studio.
-2017
Close Android Studio
On Windows open up System Properties > Advanced > Environment Variables...
Click 'Path' and then click edit
At the end of the 'Variable Value' add something like ';C:\Program Files\Git\cmd'
Open Android Studio, clean, and build again
It took me more time to find the solution.
So, I've been trying to build a project in LibGDX for about 10 hours now. In case you'r unfamiliar, LibGDX is one of those platforms where you specify a project directory at the start, along with any required SDKs and then when you're ready to start coding it will generate a project for you.
Anyway, I've been having a problem where every time I try to build it fails with the single error message:
Execution failed for task :core:compileJava.
Could not find tools.jar
I'm guessing "tools.jar" is a package within the Android SDK, as this is the only repository needed to build, it doesn't ask for a JRE or even the Java SDK. just the Android SDK.
I have been looking in the SDK manager, I have installed all of the packages labelled "Android-SDK Tools", "Android-SDK Platform Tools" and "Android SDK Build Tools" but there is nothing else that includes "tools.jar", I am looking for some light shed on this topic as it is a very grey area. I would like to know where this .jar file comes from and what exactly it includes. Can it be installed from the Android SDK?
There have been similar questions like this before which only fit narrow situations, If someone could provide a holistic description of the tools.jar package it would benefit a great deal for me and everyone else that needs it in their 3rd-party android IDEs.
For the record, it's building with Gradle and my current SDK is well-equipped enough to build full-fledged apps in Android Studio.
Please don't answer this question with a question unless I have left out some information that is dire to finding an adequate solution
Try copying tools.jar from %JAVA_HOME\lib to Android Studio\lib
For me, copying tools.jar to Android lib folder alone didn't solve my problem.
But I also had to create a System Variable 'JAVA_HOME' in Windows Environment Variables with path to the latest JDK folder.
Restarted Android Studio, and this solved by problem.
My Android Studio Version: 4.2.1
The "tools.jar" is provided by Oracle JDK which is required by android studio for compilation - I have faced this issue after updating android studio to latest version in my PC.
To Resolve the issue follow below steps:
In Android studio File -> Project Structure -> SDKs (Under Platform Settings)
A) Add JDK path by pressing '+' symbol in middle pane if suppose JDK/JDK home path is not present in the middle pane already (Middle pane also contains the Downloaded Android SDK's)
B) Java sdk will be usually present/installed in the path
64 bit => "C:\Program Files\Java\jdk1.X.Y_ABC" (In my PC it is 1.8.0_202) or
32 bit => "C:\Program Files (x86)\Java\jdk1.X.Y_ABC"
If suppose you don't have JDK installed in your PC, please download and install from Oracle Java website
https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html
Set JDK and JRE Path(Download both from webpage mentioned in step 2) in system environment variable
A) Press windows key type "Edit the system environment variables" and open the application
B) Go to Advanced -> Environment Variables
Under system variables add JAVA_HOME and JRE_HOME as below
Set Windows system environment variable
Add jdk lib path on the Path environment variable under user variables (this step is required only if the error not resolves with the previous steps)
C:\Program Files\Java\jdk1.X.Y_ABC\lib
In my case, I have five jdk and some have tools.jar and other not, my solution is copy paste this tools.jar in all lib of jdk.
Nothing worked for me. So I Copied tools.jar and pasted it in C:\Users\UMAR_\AppData\Local\Android\Sdk\platforms\android-30 which is the path to the library for the Android API 30 Platform. I pasted tools.jar in every folder and it start working.
I didn't have tools.jar initially but followed this link and downloaded https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html
Also added to a environment variable.. but what worked was in the first para, I still don't know if adding to variable was necessary or not.
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
I tried creating a new android application project in Eclipse (4.2 for Java) with latest android sdk as per http://developer.android.com/training/basics/firstapp/creating-project.html
I enter the application name and the project name. The other values are default.
After I click on finish on the final step, the window of creating a new project is still open. I have to click on 'X' to close the window. In the project explore, the new project is created but all the icon in front of files are in grey and there is no src file.
Could anyone help please? Thanks!
It seems that your MainActivity.java in "src" folder is not created at all.
You'll need to update the ADT.
Go to following:
'Help'->'Install New Software' and type
https://dl-ssl.google.com/android/eclipse/
Select ADT option and install it.
It will update the ADT.
Even I had the same problem and my issue got resolved with it!!
Make sure you have these things:
Java SDK Latest (or most popular, which is Java 7 at the moment even though 8 is available)
ADT
Eclipse is updated (via menu...Help > Check for Updates)
Check JDK Path
Via menu...Window > Preferences > Java > Installed JREs > [Point to path]
path should be similar to this for
x64: C:\Program Files\Java\jre7
x86: C:\Program Files x86\Java\jre7
x64[JDK]: C:\Program Files\Java\jdk1.7.0_45\jre
x86[JDK]: C:\Program Files x86\Java\jdk1.7.0_45\jre
