Install Gradle and its dependencies once for all Android projects

Every time I create/open a new Android project, I have to wait 5 - 10 minutes for Android Studio to download Gradle and its dependencies and configure the project, even though this is usually the exact same process for every project.
Android studio always download gradle for every new project? discusses rectifying this for a single project, but is there some way to set this all up once for all projects created in the future? MTIA!
EDIT: Just realised it would probably help to specify the version of Android Studio that I'm using, which is Arctic Fox 2020.3.1 Patch 1.
It does that to make sure you have the latest version of Gradle. Here is the way around it. Of course you may want to change the version number at the end but you get the idea.
1.- When you're opening a file on the option Gradle project: select the build.gradle that cames on your project
2.- Select the option "Use local grade distribution" and in Gradle home option; go and select in C:\Program Files\Android\Android Studio\gradle\gradle-2.2.1

Cannot run my app, asking to select Android SDK

Today I've installed Android Studio Canary 1
Now I cannot run my app. This following dialog appears.
I've already set the right SDK location through File-> Project Structure-> Android SDK location.
Expecting your help to solve this problem.
Warning Dialog image:
Go to project structure settings and set Source Compatibility and Target Compatibility to your current java development kit version:
Just you need to sync your project file with your gradle file.
File -> Sync Project with Gradle Files
I tried every answer in this post but my problem only got resolved when I made these steps:
File -> Close project -> Remove project -> Open existing project (same
project)
Maybe this will save a morning to another person with the same bug.
EDIT
This happened to me a lot on a MacBook. After I posted this answer it just kept happening so what I did was:
uninstall the Android Studio version I had from the App Store;
download the desktop stable version from Android Studio website;
start using the desktop version of Android Studio.
Never happened again.
Sometimes the SDK path will be incorrectly configured. You would need to fix it.
To Settings/Preferences( command + , on mac).
Search for SDK
Under Android SDK, click on edit and point it the root of sdk directory on your file system. (If ther is no SDk installed then install in from the below list).
i suggest you go to build.gradle and sync again.
Or Tools -> Android -> Sync Project with Gradle Files (Android 3+)
You need to insall SDK api 19 check this out.
https://developer.android.com/studio/releases/platforms
Go to sdk manager and install sdk according to your device and check your device api. Example if your device is jellybean then install api 19 sdk.
Go to Tools> Android > SDK Manager and make sure you have selected default Setting under System Setting. In this image I have selected Android 7.1.1 as default SDK
Just click on the button ..."Sync Project with gradle file"
Error will be remove
I had the same problem and what it worked for me was just sync with gradle.
I just did what I've found in this similar question:
How do I "select Android SDK" in Android Studio?
The original answer:
go to build.gradle and click sync now. Then it worked.
Update :
File -> Sync Project with Gradle Files (Android Studio 3.1.1)
Tools -> Android -> Sync Project with Gradle Files (Android Studio
3.0.1) Or You can click on the icon from the toolbar.
Sync Project Icon
This answer may not help works for later version as Android studio Team work on making the tool more better, the way to sync may be
different in the next version of Android Studio.
COMMON WAY that may helps is try to sync project and then Invalidate
Caches and Restart Android Studio.
Solution for Android Studio 3.1.2
Before that, by the way, I had invalidated cache and restarted too, but it didn't work.
Please, try and let us know.
P.S.
I had this problem after I imported a project from Git, just in case someone would like to replicate.

Android studio : when re-import the project it show's error and given a strange floders

while re-importing my project android studio show's plenty of errors
after cleaning and re-importing my project i have got an red circle with ā€œJā€ on my java files and i'am enable to run my project
Make sure that your gradle version is defined properly.
It seems that this project was on another PC and you imported it on your computer. I think that probably a gradle version conflict occurred and you have two options:
one is to let android studio download gradle version specified in TlaProject (gradle 2.4)
another solution is to edit app level 'build.gradle' file and change its version to a version which is available on your machine (to see which version is available on your system, please check 'gradle' folder inside installation folder of android studio)
My problem was solved by updating the version of android studio .

Android Studio Stuck at opening Project?

I recently updated from Android Studio 2.0 to 2.1.2 and now I have a project which doesn't open. Android Studio is stuck at the following screen for more than 10-15min.
I tried solutions from these answers.[ans1] [ans2]
but none of them work.
I can create new projects and also import projects built on eclipse. But cannot open my own project.
Please help.
Delete the gradle folder in the project folder. It will work.
For many problems such as stuck with opening or downloading something while starting
I use this sequence as an ultimate guide and on one of the steps always works out.
Recently I used it after updating to 3.2
Try File -> Invalidate caches / Restart
Shutdown Android Studio
Remove .gradle folder in the user home directory
Start Android Studio (Studio will download gradle data)
After Gradle build is done, rebuild project
According to Android Studio's Known Issues https://developer.android.com/studio/known-issues under "Configuration on demand with Gradle 4.6 and above:", if you are using Android Gradle Plugin 3.0.x or 3.1.x with Gradle 4.6 and above you should add the following line to gradle.properties:
org.gradle.configureondemand = false
This seemed to solve my issue with Android Studio getting stuck at "Project setup: reading from cache".

Writing a Gradle for a previous Project

I just started an android project for school, and I have to edit an android application that was built by previous students. I was given source files and apk but no gradle.
I imported into Android Studio and tried to run the build when I saw that I couldn't. I have looked up documentation online for the past 4 days and have so far come up with nothing other than downloading the gradle-2.7 files and running:
build gradle
in my computers shell.
Is there an easy way to build a gradle? Perhaps some tools or such? Or will I have to go through the files and write all the gradles myself?
Android Studio uses a Gradle wrapper to fully integrate the Android plugin for Gradle. You can build your Android apps from within Android Studio and from the command line on your machine or on machines where Android Studio is not installed.
Android studio comes bundled with gradle and in the screenshot I can see gradel folder, gradlew and gradlew.bat and build.gradle files. So (hopefully) all you need to take care is build.gradle files.
I would strongly suggest you to go through link
If you have time go through this course
