Android Studio build error on NTFS partition

I'm having problems building apps on Android Studio. Things work fine when the project is on my ext4 partition, but when I created a new one on my NTFS, I encountered this:
Argument for #NotNull parameter 'message' of com/android/tools/idea/gradle/project/sync/GradleSyncState.syncFailed must not be null

The error disappeared when I restarted Android Studio, but after that I still cannot run my app (the project structure in the sidebar is not displayed properly).
I'm using Android Studio 3.2 on Ubuntu 18.04.1.

I figured it out. (By mistake, to be honest...)
Let's say you have an NTFS partition mount at /mnt/ntfs, and your project is at /mnt/ntfs/projects/project.
Your home partition (ext4) is mounted at /home, your home directory is /home/user and you have a symbolic link at /home/user/projects that points to /mnt/ntfs/projects.
The reason I (and hopefully you too) have encountered this error is that when using Android Studio's "Open Project..." option, I provided the symbolic link (/home/user/projects/project). When trying to provide the real path (/mnt/ntfs/projects/project) the gradle sync succeeded.
So to fix this for now, simply provide the real path. However, this should probably be addressed by IntelliJ or the developers of Gradle.

Android Studio 3.2 sync failed after update

I updated from Android Studio 3.1.4 to 3.2. Now sync fails with the error message
Sync finish event has not been received
How can this be fixed? Invalidate Caches/Restart did not help.
The ida log shows the following warning:

The only solution I found was to remove Android Studio and reinstall Android Studio 3.2 from scratch.

EDIT
The problem might be different from OP but this is also a new issue in AS 3.2 which gives you Gradle sync error
I had Gradle sync error for the last couple of days after I updated to AS 3.2 and in my case, the problem was one of my library modules contain the following in Manifest.xml
<uses-sdk
android:minSdkVersion="15"
android:targetSdkVersion="27" />
and the solution was to remove 'uses-sdk' (in AndroidManifest.xml file) in ALL the modules in your project.

Try to look into the log of the IDE, for my case it was a flutter plugin causing the issue..
You can navigate to the logs by clicking on show log in the gradle try again strip at the top.
or
go to
~/username/Library/Logs/AndroidStudio3.5/
and read the idea.log file.

java.lang.NoClassDefFoundError:
org/gradle/wrapper/WrapperConfiguration
It seems like WrapperConfiguration class couldn't be found. Try these commands:
brew install gradle
gradle wrapper
The second line will install wrapper class. And then,
gradlew clean

Error:Android Source Generator: IndexOutOfBoundsException after PC crash

My PC has crashed occasionally, and after restart I got this, and can't run my project. What do to, who knows?
UPDATED for moderator: this is definitely Android Studio bug, so appropriate tag is important for whose who will search the same. The cause is in Android Studio's .idea file, I assume for now.

The answer is: delete .idea folder
Or better move it first to somewhere, on the case you forget something from configuration.

How to debug custom lint detector

I've written a custom lint detector based off this example repo. I'm trying to debug the detector using the tests provided however when I try to run these tests through Android Studio all I get is an error in the bottom right

Android studio 2.2 preview 5 design editor/preview seem to be broken?

After updating from Android studio 2.2 preview 4 to 5, Design and Preview tabs stopped to show previews.
They don't show anything, only the error (described below) and a tip "Try to refresh the layout".
Refreshing and choosing different options in a top bar (API, device orientation) doesn't help.
Was trying File -> Invalidate Caches/Restart. Doesn't help either.
Any suggestions?

UPD1: Seem to be an issue.

In your activity.xml file there must be a line as xmlns:app="". Delete it.

There is an error in xml file check that no
android: or xmlns:app=""

Fixed in Android studio 2.2 (Canary) Preview 6 (also see issue).
