I'm trying to use vscode to create an android application using gradle 7.3.3 and jdk 18.0.2.1 but I have an issue. It's my first time doing this and I don't realy get what is the problem. I got this error :
class.java is not on the classpath of project app, only syntax errors are reported
I probably forgot to do something to configure vscode.
I hope you can help me.
Thank you !
Recently I upgraded my Android Studio to 3.1 and also my gradle to 4.4.
Since then android studio doesn't let me open anything. (Any project , any file location, etc). I am able to create a new project but if try opening an existing one it just freezes. And then I have to kill it through Task Manager.
I am also able to open the settings page through welcome wizard. There also I tried to change the gradle version manually, again while browsing to the location it just gets hanged. Same way as above
I tried upgrading the Java version, installing/uninstalling android studio and everything else I can but its the same.
Any help or suggestions will be appreciated
I encountered similar issue. Please check the system Environment Variable, the JAVA_HOME path should be set correctly according to Java installed in your PC; something like this in my PC "C:\Program Files\Java\jdk1.8.0_172"
This resolved the issue for me.
Cheers!

I am trying to get Android Studio installed on Cent OS 6.5. I have downloaded and unzipped the package to /usr/share/applications/Android-studio/.
I have installed jdk 8 in /usr/share/applications/ (as I understand you just unpack it there, no need to compile or execute anything...?)
I have appended /etc/profile with "JAVA_HOME=/usr/share/applications/jdk1.8.0_1118"
When I execute the studio.sh file the app begins to run (I see some Java messages in the shell) then I get the error:
"JDK Required: 'tools.jar' seems to be not in Studio classpath.
Please ensure JAVA_HOME points to JDK rather than JRE".
I think this means something is wrong with my JDK files but I don't know what. I have followed multiple tutorials online about how to fix this error including the guides on Android studio and Oracle's websites and as far as I can tell I've done everything correctly, but I am still getting this error. What am I missing?
Thank you for your help.
After looking through some answers to similar questions (that didn't receive any votes so I had overlooked them previously) I solved the issue. I had to copy the 'tools.jar' file from /usr/share/applications/jdk1.8.0_1118/lib to /usr/share/applications/android-studio/lib. That did it. It is up and running. Apparently this file is missing from the package downloaded from the android studio website. I hope they fix that soon and save future users hassle.
I'm getting error:
"Gradle project sync failed. Basic functionality (e.g. eiditing) will not work properly."
And Error Log:
Error:Unable to start the daemon process.
This problem might be caused by incorrect configuration of the daemon.
For example, an unrecognized jvm option is used.
Please refer to the user guide chapter on the daemon at http://gradle.org/docs/1.10/userguide/gradle_daemon.html
Please read below process output to find out more:

I was trying to delete .gradle folder as I read here. This worked yesterday but today when I started Android Studio the error showed again and deleting .gradle folder doesn't help.
I realy don't know what to do.
Does anyone have any suggestions?
Just a blind guess: try to add something like this to your gradle.properties file in the project:
org.gradle.jvmargs=-Xmx512m -XX:MaxPermSize=512m
Same issue solve in Android studio by
File -> Settings -> Compiler (Gradle-based Android Projects)
Change the "**VM options**" to
-Xmx512m -XX:MaxPermSize=512m
It worked for me .
The only way I've been able to fix this when it happens is by doing
./gradlew clean
and
./gradlew --refresh-dependencies
and then restarting Android Studio.
If that doesn't work I usually resort to reimporting the project.
I had the Same Issue, and Searched for almost 4 Days but can't able to solve the problem.
But at Last I can able to solve the problem, and for that please follow the steps.
Step 1: Check Your Java Version.
Step 2: If It is 1.7 then Download the New Version i.e JDK 1.8
Step 3: Install JDK 1.8
Step 4: Change the Java Version of Android Studio to 1.8 and the
problem solved...
It Worked for me.
changing compile setting to this worked for me
I was getting the same error in version 2.2.3,So I downloaded the latest Android Studio version 2.3.3, even in the latest version, I was getting the same error, below is my solution :-
Download the latest version of Android Studio from the official site.
In File>Project Structure>SDK Location, JDK Location should refer a 64-bit JDK ex. C:\Program Files\Java\jdk1.8.0_131, even after this, error was not fixed completely.
I checked the project structure, In the File>Project Structure>Project , the Android Plugin version was still 2.2.3, I changed it to 2.3.3 and the build is successful and everything is working smoothly.
This one worked for me.
Close the Android Studio
Delete .gradle folder from c:\users\{username}\.gradle
Open the Android Studio
Clean Project
Rebuild Project
Sync Project with gradle files. See screen shot
Cheers!
Check if the gradle path in File -> Settings -> Build, Execution -> Gradle is correct. I had incorrect path to local gradle distribution there.
None of these worked for me, so this is how I eventually solved my problem:
In the top-level build build.gradle file, remove
'classpath 'com.android.tools.build:gradle:some version number'
sync your project and make sure your gradle location is pointing at the correct directory
Updating Java and the problem is solved!
Control panel > Java > Update Now
I was in that situation, finding near no solution; finally I realized that my firewall was blocking java executable from opening ports/connecting. Try adding a firewall exception for the Java executable. This solved the problem for me.
I have exported a project from a laptop, as an archive file. i did this through File>Export>General>Archive File. Then Import>General>Archive file. It comes up with an error saying:
"ResourceProject 'PartyOrganiser' is missing required library:

path Build Path Problem"
Could you help me to resolve this issue. It also says: Unable to resolve target "android 19"
Thanks for the help!!!
In the other laptop try to have android 19 version
I too had the similar problem. If you already have android-19 lib but still the error persists. Try compiling the project with some other android version like 4.4 or GDK or anything and then again compiling with your required version. After that, if the problem persists, then try to go to properties, and then libraries, and then try deleting the libraries which are causing the problem. I hope it helps.
