I am new to android studio and I tried building a program but my code is full of errors and the most common is “can not resolve symbol”. Please what do I do?
Clicking the button Sync Project With Gradle Files should solve it:
Tools -> Android -> Sync Project with Gradle Files
If that fails, try running 'Rebuild project':
Build -> Rebuild Project
In the case you are with Android Studio 3.1 or above, you should go to:
File -> Sync Project with Gradle Files

I have gone through similar question on the internet. But I am still unable to find a solution for it.
To begin with I am trying to understand gradle and how android studio builds gradle files.
I have read about gradle and how it is structured. I have understood that it is similar to make in linux, so it builds all of the necessary files to create apk. But i could not understand how android studio generates all the gradle files. Is there a main file which is executed and which generates all of the other gradle files.
My project was working properly until i had to sync the gradle files and now it is giving me "Gradle project sync failed" error. I have tried out existing solutions on the internet, like
1.Invalidating caches and Restarting
2.Settings -> Build, Execution, Deployment -> Gradle turning on Online mode here, which i could not find on the android studio version 4.0.1
3.Opening up Gradle build console from View -> Tool Windows -> Gradle which i could not find.
I can't see the module level and project level gradle files amongst others, should I manually add them?
Should i download a new gradle file and point it separately? Is there any way to fix it by executing the right gradle file and generating the rest of it.
Where can I read more about it and have a better understanding of gradle.
Better install a new version of android studio. i think you have updated your gradle plugin.
I had that problem and I just updated my Android studio. It worked!
go to: Help->Check for updates
I am trying to run/debug the application in android studio version 3.6.2 but returning an error saying Cannot parse result path string:
Build output box shows:
Build failed:
Cannot parse result path string:
The problem is with the gradle version
I simply had to switch from version 6.5 to 6.5.1 and after rebuilding it worked just fine.
If you are on windows go File -> Project Structure, on project change the gradle version.
The problem might be the gradle version. Using a gradle version above 6.5 should fix the problem to allow the build to complete. If the problem persists, I would suggest reinstalling android studio with updated gradle version.
To change gradle version: Navigate to file-> project structure and access the dropdown menu besides gradle.
Go to gradle project >>update dependencies classpath .
Thats all
This seems to be a issue with gradle cache. Try below methods
Method1: Try invalidate cahce/restart option from menu.
Method2: Clear the gradle cache manually by deleting "cache" folder from the below location "C:\Users\USER_NAME.gradle\caches"
Everytime whenever I start a new project it shows the gradle sync is failed[![enter image description here][1]][1]....is this necessary to sync the gradle every time whenever i start a new project
What is synced here is the project configuration expressed in the *.gradle files with the project configuration native in Android Studio. So, yes, this is necessary for each project. It is also necessary after you made changes to any of the *.gradle files.
Yes,Whenever you open a project in android studio,it will sync the gradle files everytime,And when you edit or implement any new library in .gradle file,that time also gradle build sync.
In your project gradle build is keep failing,this happens when your code have some error or its possible that error is in .gradle file.
I have checked for any implementation mistakes in gradle files or other mistakes in Java code and couldn't find any.
I'm getting this error :
'Could not delete path 'C:\Users\admin\AndroidStudioProjects\BreakTip\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values-fa'.'
Why is it trying to delete the path when I want to build the project?
Is there any solution?
Maybe there is problem because of some version, try to update Realm plugin to 4.2.0.
See: https://github.com/realm/realm-java/issues/5521
In latest releases of Android Studio one option has been added to Clean the project.
Build > Clean Project
After this step rebuild project :
Build > Rebuild Project
I've made pretty much a fresh project. I added in the gson library by google to my projects /libs directory and added it as a library. I also added it into my build.gradle as
compile files('libs/gson-2.2.4.jar')
So now everything looks ok, there aren't any errors given by Android Studio, no red underlines anywhere. I can build it and give it a shot.
But then I run into this error:
java.lang.NoClassDefFoundError: com.google.gson.Gson
Which I can see in the debugger. The thing is i've added it in and android studio can see that but come build it gives me all these sorts of problems.
What am I doing wrong?
Had the same issue. What I did was gradle clean and then build my project with gradle from console. In my build.gradle gson dependency looks like this:
dependencies {
compile 'com.google.code.gson:gson:2.2.4'
}
Something went wrong in incremental build system. One of this should help:
Menu Build -> Rebuild project
Delete folder /build
Close Android Studio, delete /build folder
Right click on your project -> "Open module settings" -> Dependencies tab -> check if Export is checked for your library
I'm using Android Studio. and in my case, gradle clean and/or Rebuild project didn't work.
I had to uninstall the current SDK (in my case: 22) that was supposed to be corrupted and then reinstall it. After doing this, the project restarted to compile and run. Hope it can help someone.
