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

LLDB exception after updating to Android Studio 3.1

After updating to Android Studio from 3.0.1 to 3.1, and updating all plugins and SDK tools i am no longer able to debug my native application.
The error is 'Execution finished' (ExecutionFinishedException) which is raised in LLDB.
LLDB version is 3.1.4508709 (which is the latest).
If i try and debug with an earlier version of LLDB i get an error LLDB is missing (or similar).

Anyone else experienced this or know of a fix?

A workaround is to re-install Android Studio 3.0.1. This can be done alongside the latest version (see https://developer.android.com/studio/preview/install-preview.html).
For me, debugging c++ code then works again (in Android Studio 3.0.1) even though it is using the same versions of SDK tools (e.g. LLDB v3.1.4508709).

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

How can i pass this error and create a new project now?
*Note: my SDK is full and I have every platform in it

It is not stuck, it will take some time normally 5-7 mins , it also depends upon internet connection, so wait for some time. It will take time only for first launch.
Update: Check the latest log file in
C:\Users\.gradle\daemon\x.y
folder to see what it's downloading.Here is the answer

I have resolve this by installing bundle version.

"IllegalArgumentException" in SonarQube Community plugin

Recently, when I try to analyze code in Android Studio (Analyze > Inspect Code) I always obtain this error:
11:35:28 IllegalArgumentException: Argument for #NotNull parameter 'sonarServerName' of org/intellij/sonar/persistence/SonarServers.get must not be null
In other projects it works fine. When IllegalArgumentException link is clicked, this screen is shown:
Obviously, I don't want to disable plugin.

Anyone has experienced this issue? Where is the problem and what can I do to resolve it?

You should configure a SonarQube server to use as per the README from the plugin repository:
After the installation, you first of all need to configure the
connection to your Sonar server. This is done per project and/ or
module. You can use a remote server or a local one on your machine.
In your IDE go to Preferences -> SonarQube.
Click Add, enter the address of your Sonar server and the credentials (if needed) and click OK.

This error can also be thrown when you created the server in the project settings but not in the global settings. You have to select & add the server in the global settings as well.
