Updating created problems with Gradle

this is my very first post, Big Deal to me, appreciate your help Colleagues.
I recently updated Android Studio, (this is why I don't like updating) it forced me to create a new gradle file it called Hello ESE.gradle (ESE being the Company's name), the file simple contains this :
group = "itet"
version = "1"
the updating placed this file in the res/values directory when I built, this caused an error saying the file needed to end in .xml,
FAILURE: Build failed with an exception.
What went wrong:
Execution failed for task ':app:mergeDebugResources'.
/Users/lokeke/AndroidStudioProjects/CalorieCountdownAppforAndroidBrown/app/src/main/res/values/Hello ESE.gradle: Error: The file name must end with .xml
I thought a gradle does not belong in the values directory so I removed it and put in the build directory but now the errors are even worse, I moved this Hello ESE.gradle to other places where gradle could look for it but still nothing works it won't build, don't know what to do now (how I wish I could go back to pre-update!!!)

I just simply updated all the tools I was using, Gradle, SDK, the works, and transferred to the Hello gradle file to the gradle.properties directory, this seems to have fixed it.

Build error related to Jar file in Flutter

I am working on flutter and trying to include map_view in my app. But I have a build error as:
FAILURE: Build failed with an exception.
* What went wrong:
Could not resolve all files for configuration ':map_view:androidApis'.
> Failed to transform file 'android.jar' to match attributes {artifactType=android-platform-attr} using transform PlatformAttrTransform
> java.io.FileNotFoundException: C:\Users\Harsh Goyal\AppData\Local\Android\sdk\platforms\android-27\android.jar (The system cannot find the file specified)
It seems to be related to some missing file. I dont know what to do and can't find any solutions!
Any help is appreciated. :)

I just reinstalled my Android SDK and everything worked perfectly. An answer was posted on a github issue where I posted this question. Here is the link in case it is required:

android.jar file must be broken or missing.
Download and paste .jar file from https://github.com/Sable/android-platforms according to your api level.
Usually you don't need to restart. If doesn't works, restart and retry

Android Error Cannot resolve symbol 'R'

I am having trouble with getting rid of the error Cannot resolve symbol 'R'. I have done some research but none has worked. Among the tips i have tried out include Tools->Android->Sync Project with Gradle Files after which I executed the Build->Clean Project. The clean project command resulted with the following error;
Execution failed for task ':app:mergeDebugResources'. > Crunching Cruncher abc_btn_radio_to_on_mtrl_000.png failed
My xml files have the following error:
NOTE: This project contains Java compilation errors, which can cause rendering failures for custom views. Fix compilation problems first
Exception raised during rendering: action_bar
What might I be missing? I will appreciate any help or pointers.

In the comments above, #Udit posted a link to another sort of related question from which I was able to get a solution. Incase you run into a similar problem, the solution is quite simple. Reboot Android Studio and then go to Build->Rebuild Project. Hope this will sort out your issue as it did mine. Thank you all for your contribution.

Execution failed for task ':app:mergeDebugResources'. > Crunching
Cruncher abc_btn_radio_to_on_mtrl_000.png failed
--->Is this error message from the gradle console?
Because this happened to me once when the PNG file I used wasn't a "pure" PNG file. Like for example: An image I found from the internet that wasn't really a PNG file(ex: jpg/Gif image) but I just renamed it to to a ".PNG" file upon saving it then directly copied this to res/drawable. So to fix this I deleted the image and used a real PNG file by either editing it on Photoshop or a real png file from the internet or whatever and then did #Biko's advice which was to Reboot Android Studio and then go to Build->Rebuild Project.

Android - Gradle: Copy to native-libs

I am very new to the Android / Gradle build environment, and google helpt me a lot, but for this I have tried a lot of things, but can't seem to get it to work!!
When I try to load the Vitamio Library (its saved as .jar file inside /app/libs/vitamio/, everything goes well, there are no Gradle build error.. But when I start the app, it gives the error that 'vinit.so' cannot be found.. The solution is copying it manually to the static-libs....
See problem -> Vitamio Sample Error - java.lang.UnsatisfiedLinkError: Couldn't load vinit findLibrary returned null
Now my folder structure is as following:
ATTEMPT 1
Android Studio, Gradle, OpenCV and NDK
Error:(69, 0) Could not find property 'jniLibs' on task ':app:packageDebug'.
When I try with jniFolders, nothing happens.
I placed it inside a lot of folders, just to try.. But it doesn't make any difference...
UPDATE 1
I think the copying worked, I had to install NDK and add it to local.properties file, but now it gives the following error:
Error:Gradle: Execution failed for task ':app:compileDebugNdk'.
A problem occurred starting process 'command '/android/ndk/ndk-build'
Without any errors.. Any help in find a debug.log somehwere, because the error says nothing about whats going wrong...

Gradle lets you handle dependencies a lot easier than using JARs! Open the app build.gradle file (there are two, open the first one in your screenshot that you posted) and add this line:
compile 'me.neavo:vitamio:4.2.2'
in the dependencies section.

Android Studio Keep saying Failed to complete Gradle execution

Everything fine with the command line
gradle build
But Android Studio keep saying that
Failed to complete Gradle execution
Cause:
A fatal exeption has occurred. Program will exit
If I clear all the cache, and restart everything will be fine, but this dialog will easily comeback again (after a build fail). I guess that the increment build chain is not good, but the message is not helpful at all.
Are there anythings I can do to get a more details message about what going on, why AndroidStudio Gradle failed? where can I put thing like --stacktrace in the Preferences of Android Studio?

If you got a problem like this in Android studio, then don't worry about that, you are missing some thing which are here.
Go to File-->Setting-->Gradle-->Gradle Vm Option,
Now put this value -Xmx256m in the box, and hit the Apply button.
Here you have solved the problem.

At my case, I forgot to include some jars at Libs folder at the Gradle file, actually I forgot to add ".jar" to the end of jar file name.

In my case, it was not VM Option and Clean and Build did not work. My problem was that there were some images in res folder (so no grammatical errors) and Android Studio/IntelliJ return this error and saying nothing about images... check all external data sources in each file.
