Android Studio Error "Minimum supported Gradle version is 7.0.2. Current version is 6.8."

An error occurred after I downloaded version 6.8 and the latest version of Gradle.
A problem occurred evaluating project ':launcher'.
< Failed to apply plugin 'com.android.internal.version-check'.
<< Minimum supported Gradle version is 7.0.2. Current version is 6.8. If using the gradle wrapper, try editing the distributionUrl...
What do I have to do?
I'm attaching more details in the added pictures.

The error:
Minimum supported Gradle version is 7.0.2. Current version is 6.8.
Likely means:
Your "\gradle"-folder is missing from your project folder:
(Note: Not to be mistaken for the ".gradle"-folder which is a different folder)
Solution:
Get a copy of the "\gradle"-folder from another working project (or create a new project).
Or:
Your "\gradle\wrapper\gradle-wrapper.properties" has an incorrect value in the "distributionUrl=":
Solution:
Change the value in "\gradle\wrapper\gradle-wrapper.properties" to
distributionUrl=https\://services.gradle.org/distributions/gradle-7.0.2-bin.zip
I hade the same problem after moving my project to another computer:
Minimum supported Gradle version is 7.0.2. Current version is 6.8.
Please fix the project's Gradle settings.
Gradle Settings.
Clicking on the "Gradle Settings"-link opened the Gradle settings Window, but the Gradle JDK was already correctly set to version 11:
So my next step was to check the Project Structure:
And update the Gradle Version to 7.0.2:
But that led to this error instead:
¤ What went wrong:
An exception occurred applying plugin request [id: 'com.android.application']
» Failed to apply plugin 'com.android.internal.version-check'.
» Minimum supported Gradle version is 7.0.2. Current version is 6.8. If using the gradle wrapper, try editing the distributionUrl in D:\Files\Code-Project\gradle\wrapper\gradle-wrapper.properties to gradle-7.0.2-all.zip
Now the error points me towards a problem within the "\gradle\wrapper\gradle-wrapper.properties"-file.
Looking into that I found out the real problem - the "\gradle"-folder was completely missing.
(Note: The "\.gradle"-folder is not the same as the "\gradle"-folder)
Copying the "\gradle"-folder from another project solved my problems.
Now my "\gradle\wrapper\gradle-wrapper.properties"-file looks like this:

Next update the Gradle Version in Android Studio select invalidate cache and restart solve the issue.
Go to Menu File->Invalidate cache..-> Invalidate and Restart.

Go to gradle wrapper properties
In the distribution url line change gradle version from 6.5 to 7.0.2 or the current version when you see this

The error says that the gradle version in your system is less than your project's gradle verion. That's the reason why it is unable to compile your project.
System gradle version < Project's gradle version
So there are 2 solutions here,
Change the distribution URL in the gradle-wrapper.properties file in the android/gradle/wrapper directory to distributionUrl=https\://services.gradle.org/distributions/gradle-7.0.2-bin.zip.
Update your gradle plugin. If you use some environment variable, download the latest verion from Gradle | Manual Installation and replace it with your current one. Don't forget to update the path variable in system properties.

Firebase performance monitor causing "D8: Unsupported source file type"

I added
apply plugin: 'com.google.firebase.firebase-perf'
and when I ran build script I got
/transforms/FirebasePerformancePlugin/dev/debug/174/module-info.class:
D8: Unsupported source file type
What kind of problem it could be?
I updated all plugins, play services, and Android Studio, but with no luck

I Solve This issue by updating gradle version
classpath 'com.android.tools.build:gradle:3.5.3'

Update: Android Gradle Plugin 3.5.0 fixes this. See this issue and this one issue, both fixed.
(Unfortunately, in my project, this other issue still remains even in 3.5.3.)
I started getting the same error after updating a (company internal) library dependency, but then I kept getting it even after reverting that update. Very strange!
> Task :app:transformClassesAndResourcesWithR8ForBetaRelease FAILED
R8 is the new Android code shrinker. If you experience any issues, please file a bug at
https://issuetracker.google.com, using 'Shrinker (R8)' as component name. You can
disable R8 by updating gradle.properties with 'android.enableR8=false'.
.../transforms/FirebasePerformancePlugin/beta/release/66/module-info.class:
D8: Unsupported source file type
The only thing I found that helped was to do what the Gradle build output says and temporarily switch back to ProGuard, with:
android.enableR8=false
in gradle.properties.

This issue was fixed somewhere between Android Studio 3.5 Beta 2 and Android Studio 3.6 Canary 5, there were a bunch of similar issues with module-info.class.
In my case to fix issue I had not only update Android Studio, but also update gradle plugin.
Steps is:
Install new version alongside your stable version (You also can configure current version to use updates from canary chanel)
More info here
Download link (I downloaded 3.6 Canary 5)
After you installed new Android Studio update grade plugin:
in
gradle/wrapper/gradle-wrapper.properties
chande distributionUrl to
distributionUrl=https\://services.gradle.org/distributions/gradle-5.5-all.zip
Don't forget Build->Clean Project

Turn off Firebase-performance plugin.
Android Studio 3.6 Canary 1 has this issue too.
I didn't find another way to release build my project.

i solve this problem with 3 steps:
1.update the "distributionUrl=https://services.gradle.org/distributions/gradle-5.6.4-all.zip"
2.update the "classpath "com.android.tools.build:gradle:3.6.3"
3.update the Studio 3.6.3
in other way(i don't like it)
//apply plugin: 'com.google.firebase.firebase-perf'
...
//classpath "com.google.firebase:perf-plugin:1.3.1"

Old version of gradle is required error

I had a three year old Android Studio which I just upgraded to the latest version(3.2).
I opened a project and tried to run it, but I got this error:
Gradle project sync failed. Basic functionality (e.g. editing, debugging) will not work properly.
Then, I saw this in gradle-wrapper.properties:
distributionUrl=https\://services.gradle.org/distributions/gradle-2.2-all.zip
From what I understand Gradle 2.2 is not compatible with Android Studio 3.2.
distributionUrl=https\://services.gradle.org/distributions/gradle-4.9-all.zip
Now however, if I try building again, I get this error:
Gradle version 2.2 is required. Current version is 4.9.
Why does it ask me for an old version of Gradle?

There are TWO places to be aware of:
Android Gradle Plugin version.
Android wrapper version and Gradle version
Each version of Android Gradle Plugin version requires a minimum version of gradle version. For your case, it looks these two versions are not in sync. So, try to modify your files as below:
Top level build.gradle
buildscript {
repositories {
...
}
dependencies {
// This is the Android Gradle Plugin version
classpath 'com.android.tools.build:gradle:3.1.3'
}
}
gradle-wrapper.properties
distributionUrl=https\://services.gradle.org/distributions/gradle-4.9-all.zip

Android studio doesn't support that version unfortunately. My advice is using 4.4, that's last full supported version.

Downgrade Gradle from 3.3 to 2.14.1

Long story short: My android phone keeps disconnecting from ADB. I was told to update android studio, did that. I open my project in Intellij and try to run on android and I get an error:
BUILD FAILED
Total time: 48.986 secs
Error: /Users/me/Desktop/comp/Development/comp-ionic/platforms/android/gradlew: Command failed with exit code 1 Error output:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':compileDebugJavaWithJavac'.
> java.lang.NullPointerException (no error message)
My first thought is that my gradle is the wrong version. For this specific app, I need to use gradle version 2.14.1.
When I type gradle -v I'm getting version 3.3.
Is there a way to delete/downgrade gradle from 3.3 to 2.14.1?
Or is this another problem?

If you're using the gradle wrapper, then there'll be a folder in your project named "gradle" with a subfolder named "wrapper", inside that, there are 2 files:
- gradle-wrapper.jar
- gradle-wrapper.properties
Open "gradle-wrapper.properties" and change the place where it says "3.3" to "2.14.1". Then sync gradle, and it will automatically download 2.14.1.
If you're using the new 2.3 Android Studio, you HAVE to use gradle wrapper 3.3, as its the minimum supported gradle wrapper version. If so, then you'll have to download Android Studio 2.2, or fix whatever issue you have in your project that needs gradle wrapper version 2.14.1.
To get more information about whatever the issue is, try running this:
./gradlew clean assemble -stacktrace
That will clean your project, try and compile it, and if/when it fails, it will show you a stacktrace of the error.

What you should do is to change the gradle build tools version to the one that matches your gradle version. According to here you can set the gradle to 2.14.1 by changing build tools to lower than 1.0.0.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.0.0'// For gradle 2.2.1 - 2.3
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
Notice: if you keep checking the mentioned link you'll see Higher is better for gradle.

For me, Android Studio > File > Invalidate Caches / Restart did the trick.

I got the same problem when upgrading to Android Studio 2.3.1. There is something funky about Gradle 3.3 (It fails by "java.lang.NullPointerException: null value in entry: destinationDir=null at com.google.common.collect.CollectPreconditions.checkEntryNotNull(CollectPreconditions.java:33)").
Good news: seems like the current most recent version (3.5) works.
Go to File|Project Structure|Project, and use these versions:
Gradle version=3.5
Android Plugin version=2.3.1

I update the Android Studio version to 3.3 Canary 4, then update the gradle plugin, and the project stops working.
I do not know how to restore my AS to the previous state, nighter the gradle plugin.
But just with this command, the project now works, for me: gradlew clean assemble -stacktrace, in terminal tab in AS.

Getting error "Gradle version 1.10 is required. Current version is 1.12." when executing "gradle wrapper"?

I'm trying to execute gradle wrapper for an Android project, and this error is raised:
A problem occurred evaluating root project 'myapp'.
> Gradle version 1.10 is required. Current version is 1.12. If using the gradle wrapper, try editing the distributionUrl in /Users/dude/myapp/gradle/wrapper/gradle-wrapper.properties to gradle-1.10-all.zip
My wrapper task in build.gradle looks like this:
task wrapper(type: Wrapper) {
gradleVersion = "1.12"
}
I recently updated to Gradle v1.12 via Homebrew. Is it not supported or something? If so, where can I check this sort of thing?

A particular version of the Gradle Android plugin requires a particular version of Gradle (at least for now), and it seems that your version of the Gradle Android plugin requires Gradle 1.10. You might find more information on this in the documentation for the Gradle Android plugin.
PS: The wrapper task above creates the files necessary to run Gradle with the (generated) gradlew script, which is the preferred way to run Gradle (no manual install, every build can specify in its gradle-wrapper.properties which Gradle version it needs).

The version of Android gradle plugin needs to be compatible with the version of Gradle. Checkout the version compatibility mapping table here：
http://tools.android.com/tech-docs/new-build-system/version-compatibility

I had the same problem. It turned out that the old Android Studio created gradle related files one level above my application folder. In my case, the path was in ~/git/, and my project was at ~/git/myproject. I used Android Studio RC2 now, and no matter how I changed the config within the project, gradle still wanted to use the old 1.10 version. Therefore, I re-checked out the project a new path, and updated the gradle version reference within the project, then it compiled.
