Cannot find AGP version in build files & empty Android Gradle Plugin Version

Android Studio Upgrade Assistant recommends to update Android Gradle Plugin from version 7.0.0. to x.x.x. However, the problem is that it alerts "Cannot find AGP version in build files". I'm struggling with this message and I found the empty AGP version in my project structure. I've already checked
gradle-7.3-bin
inside
C:\Users\abc.gradle\wrapper\dists' and allocated 'Gradle user home'
as 'C:\Users\abc\.gradle.
That dropdown button below the 'Android Gradle Plugin Version' has nothing and I want to find out why and how to fix it. Is this related with the AGP upgrade?

I got the same error when in Android Studio I tried to use Tools > AGP Upgrade Assistant.
For those who don't know, the Android Gradle Plugin is the dependency com.android.tools.build:gradle: specified in the project-level build.gradle (to be clear, not my module-level build.gradle).
In my case, the problem was that my project-level build.gradle file specified the version of the Android Gradle Plugin using a variable rather than hardcoding the version.
My project had the following variable in my gradle.properties and referenced it in my build.gradle file:
gradle_version=7.2.2
It referenced it in the project-level build.gradle file like this:
classpath "com.android.tools.build:gradle:$gradle_version"
To fix the problem, I changed my project-level build.gradle file from this:
classpath "com.android.tools.build:gradle:$gradle_version"
To this:
classpath 'com.android.tools.build:gradle:7.3.1'
After that change, Tools > AGP Upgrade Assistant stopped complaining "Cannot find AGP version in build files". Furthermore, I was able to use AGP Upgrade Assistant to upgrade from com.android.tools.build:gradle:7.2.2 to com.android.tools.build:gradle:7.3.1.

Unsupported method: AndroidArtifact.getBuildConfigFields()

I have just updated to Android Studio 4.0 and trying to build my project. I keep on getting the below error
Unsupported method: AndroidArtifact.getBuildConfigFields().
The version of Gradle you connect to does not support that method.
To resolve the problem you can change/upgrade the target version of Gradle you connect to.
Alternatively, you can ignore this exception and read other information from the model.
I am already using the latest version of Gradle and Gradle Plugin
Gradle version:
distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-milestone-1-all.zip
Gradle plugin tools version:
classpath 'com.android.tools.build:gradle:4.1.0-alpha10'
Any solution or fix for this problem would be helpful. Thanks in advance.

Use Android studio 4.1 preview
or
classpath 'com.android.tools.build:gradle:4.0.0'

This is usually due to a mismatch between your Android Studio versions and the Android Gradle plugin.
You can find the version of Android Studio on the project selection window when you first open it (or in "Android Studio > About Android Studio" on Mac, and similar location on other platforms). For example, you might be using Android Studio 4.0.1.
You can find the Android Gradle plugin version for your project in the top-level build.gradle file.
You should find something like the following:
buildscript {
[...]
dependencies {
classpath 'com.android.tools.build:gradle:4.0.1'
[...]
}
[...]
}
You need to make sure that the two version numbers match (in this case they do).

Fix Plugin Version and Sync Project

I have recently updated my Android Studio.
After updating it, When I am trying to import or open a project it gives me following error :
Gradle Sync Issue
Error:Error:Gradle 2.4 requires Android Gradle plugin 1.2.0 (or newer) but project is using version 1.1.0.
Please use Android Gradle plugin 1.2.0 or newer.
Fix plugin version and sync project
Is there any solution for this problem ?

In your build.gradle you should use a newer version of the gradle plugin.
Use classpath 'com.android.tools.build:gradle:1.3.1'instead of classpath 'com.android.tools.build:gradle:1.1.0'. Or at least 1.2.0, as the error points out.

change in your progect build.gradle file
dependencies {
classpath 'com.android.tools.build:gradle:1.2.3'
}

As Android Studio was just officially updated to 1.3 (Gradle as well).
Please Change gradle version to 1.3.+ in build.gradle . It should now look like this:
dependencies {
classpath 'com.android.tools.build:gradle:1.3.+'
// in the individual module build.gradle files
}

I met this question,too. Modifying dependencies stuff is confuse me. From#Mykaelos answer, For Windows Android Studio, Go into File > Settings > "Build, Execution, Deployment" > "Build Tools" > Gradle and change it to "Use default gradle wrapper (recommended)", I tried it in early hours, and it works for me.

Can't open Android samples using Android Studio

I just started using Android Studios and wanted to look at some of the sample code that Google already provides in their apk samples.
However, when I try importing a project, it tells me:
"You are using an old, unsupported version of Gradle. Please use version 1.8 or greater.
Please point to a supported Gradle version in the project's Gradle settings or in the project's Gradle wrapper (if applicable.)
Consult IDE log for more details (Help | Show Log)"
In my .gradle/wrapper/dists, I have gradle-1.6-bin and gradle-1.8-bin.
I tried updating the gradle to 1.8 from 1.6 in the gradle-wrapper.properties file in the project itself, but I can't seem to save the file after editing it.

Step 1: Change line in build.gradle:
dependencies {
classpath 'com.android.tools.build:gradle:0.6.+'
}
Step 2:
In the YourProject.iml file, delete the entire component name="FacetManager" tag.
Step 3
(Maybe not necessary): In the Android SDK manager, install (if not already installed) Android Support Repository under Extras.

I was able to fix this by using the file path to my gradle directory:
C:\Users\xxxx.gradle\wrapper\dists\gradle-1.12-all\2apkk7d25miauqf1pdjp1bm0uo\gradle-1.12
the import continued fine.

This is duplicate of Unable to import Eclipse project to Android Studio (when using default gradle wrapper)
Answer:
I had to edit the gradle wrapper settings in
gradle/wrapper/gradle-wrapper.properties and change gradle version
to 1.8.
./gradle/wrapper/gradle-wrapper.properties :
#Wed Apr 10 15:27:10 PDT 2013
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=http\://services.gradle.org/distributions/gradle-1.8-bin.zip
I had to change gradle-1.6-bin.zip to gradle-1.8-bin.zip. I guess
the old ADT plugin from eclipse which generates this file still uses
the old URL.

If all the other solutions here do not work (they are all from 3 days ago)... I found...
I had secondary project in my settings.gradle and each of those projects had their own build.gradle. The Android Studio IDE says that you need to uddate to 0.6.1 but it points to only the first-project build.gradle - I had to manually locate the secondary build.gradle file for those projects and make sure all said 0.6.+ instead of previous versions.

Change gradle to 0.6.+ as ling has suggested, and also in your gradle-wrapper.properties file, change the distributionUrl to http\://services.gradle.org/distributions/gradle-1.8-bin.zip.
