Flutter: How to import existing Flutter project, as a gradle project - android-studio

How to import existing Flutter project, as a gradle project? 'Import Project' wizard asking for Gradle home path.
I have gradle, installed in my system. But what (which path) needs to set here.
Here is, what I'm trying:
Error

I had also gone through this problem where I have to import the existing Flutter project in Android Studio. I was able to import the project following below steps:
Open Android Studio
Goto File -> Open -> In Open File or Project window select the project you want to import.
Once you have done above steps try to resolve warnings shown in the log window. Warnings may be like update dependencies used in the project, etc.
Hope it will help you out.

I faced the same issue.
The gradle home directory (on my Windows machine) is located under:
C:\Program Files\Android\Android Studio\gradle\gradle-4.1
(please check the gradle version).
This will allow you to open the project. Then, you will most certainly need to "upgrade to gradle".
If this does not fully work, you might also consider using Visual Studio Code, which makes the "import" much easier: simply open the folder where you project resides. Optionally, you will have to resolve missing packages (-> Fetch packages). It should then be possible to run the project.
Hope this helps.

File - Open - Select the project root directory
Open Flutter settings from the tip menu - Click the pull-down menu, then flutter sdk dir appeared
Run
Or you can just use the flutter run command after step 1.

If you first add the flutter plugin for Android studio, then you can directly import the project as an Android Studio project and it should work fine.

In my case, having Android Studio 3.4.2 and Flutter 1.7.8, I only needed to:
1 - Open the project with the option "Open an existing Android Studio project".
2 - Run "flutter pub get" to get the packages listed in the pubspec.yaml file.
3 - Run the project with "flutter run"
If you are using Google services, don't forget to add your google-services.json file in your project. In another case, the project will fail without a clear message when you try to run it.

For Import exiting Flutter project.
Please choose Import Project because of Android Native application mean import use of android app only.
So use File -> Open -> Select Project root directory.
After open if ask for dependencies then Choose to Get dependencies

Unable to open flutter project on android studio after upgrade

Yesterday I've upgraded my Windows 7 SP1 Powershell from 2 to 5.1, and upgraded flutter and dart to latest version using the flutter upgrade command, all worked fine, and I continued working as normal. Today after trying to access my project again I got a couple of errors, and all of my project structure gone. What can I do? and why that happened? Was that due to the upgrade? or something else?

Please correct the file content
Just delete .idea folder from project directory an re run android studio. it worked for me.
The problem is caused by <projectname>.iml inside the root project folder.
First cut the file from the folder and paste it somewhere else
Restart Android Studio
Close it again and put <projectname>.iml back into the root folder
Restart Android Studio once again
simply cut the (PORJNAME).iml into the desktop and re-run the IDE or android studio.
after re-running close the ide again and move back the (PORJNAME).iml to their own place,
and open the ide
Don't delete or rename any file in your project
but when you update flutter, you must have compatible version from other plugins and dependencies with your new version, so
do this steps and run again it will be ok:-
1- Close android studio and open it again
2- From terminal tab down in android studio run (flutter clean)
3- From terminal also run (flutter doctor)
4- Then run (flutter doctor -v)
5- After all at last run (pub outdated)
6- Close android studio and restart
7- Run your project and enjoy.

Flutter in Android Studio: Build Bundle/APK greyed out

I installed Flutter and Android Studio following this link here:
https://flutter.dev/docs/get-started/editor
I've been coding in flutter for two months now and can run my app in simulator or on a connected device no problem.
But when I try to actually build an apk via "Build" --> "Build Bundle(s) / APK", this option is greyed out.
Android Studio: 3.3.2
You can't build apk using Build option in Android Studio if you are running your Flutter project.
There are 2 solutions to build it.
In terminal, write flutter build apk (this will build apk for release version not the debug version)
Open your module in Android Studio and you can use Build option of the Android studio to build the debug apk.
For option 2, you can go to build.gradle file and you should see an option in Android Studio asking you to open the module separately (see the screenshot) Tap on this option and you can then build your apk in both debug and release mode.
I realize this might have already been answered, but I have another solution to this issue. I was having the same problem after modifying my pubspec.yaml file, so after trying to build within terminal nothing would happen. Apparently, you have to open the .yaml file within Android Studio from your project directory in order to for AS to realize that there's been a change to the file. After I opened the file from the project folder, the option for Build > flutter > Build Bundle(s) /APK > Build App Bundle finally reappeared again. Just sharing my experience and hope it can help someone else who may come across this rather strange issue.
Reopen the project from your projects directory, not from recent projects option. This solved for me
Please follow these steps:-
Go To Project Structure>Project>NOSDK
Change NOSDK to the latest
ANDROID API PLATFORM
Then go to MODULE and DO THE SAME

Error running android: Gradle project sync failed. Please fix your project and try again

Android Studio (1.2 RC0) keeps telling me
Error running android: Gradle project sync failed. Please fix your project and try again.
How can I find out what the problem is? Unfortunately the solutions from this SO thread did not help.
Goto File -> Invalidate caches / Restart
Shutdown Android Studio
Rename/remove .gradle folder in the user home directory
Restart Android Studio (It will download gradle metadata and data)
Gradle build succeed
Rebuild project. Done.
Solution is
Connect your computer to the internet
Click
Sync project with Gradle files
On toolbar
It will automatically sync the gradle.
Just ignore the error and try running the project anyway.
It will fail, but this time you will get a link in the error description. Clicking the link will trigger the automatic update/download of the outdated/missing component.
In my scenario, the project failed to launch two times, each time another API/SDK component being the culprit.
In my case I was just trying to launch a sample project I downloaded, having no clue what API level was being targeted or where to look for this information.
Download the latest Gradle package distribution for example (gradle-2.11-all.zip).
Extract this zip file in a folder as for example (D://Gradle)
Load your project in Android Studio and go to File->Settings->Gradle. Click on Use local Gradle distribution and point it to the folder where you unzipped the latest Gradle project.
Restart your project
It is a very common issue and the solution is very easy...
Just update the SDK in SDK manager(see full instructions below)
Open Android Studio and go to your SDK Manager(File>Settings>SDK
Manager)
Check for (-) icon in front of any package and click on it.
Click OK to start updating the SDK.
Thanks for asking that question :)
Delete "build" folder from project's root folder. Then do "invalidate cache and restart". This will restart your Android Studio and then build the app again, will solve the issue.
Go to
file->settings->build,execution,deployment->gradle.
(and set gradle home path from your directory)
If no error messages are shown: sometimes the command-line gradle shows them. Just go the the command-line, change to the app directory and type
gradle installDebug
or, if the details are missing
gradle --info installDebug
This can provide additional information how to debug the problem.
I had the same issue yesterday. After opening the "Android SDK Manager", updating all packages and restarting Android Studio, the project compiled again.
For me, the problem was the SDK Tools License had not been accepted. Clicking on the "Build" tab at the bottom uncovered the issue.
From there, I went into the AVD, uninstalled the tools and then reinstalled them, which prompted to accept the license.
All of these have not worked for me, what did is reading the very bottom of the log file located around here
C:\Users\madri\AppData\Local\Google\AndroidStudio2020.3\log\idea.log
and it said the following
So i fixed the problem by going into Tools > SDK Manager and installing the required SDK version
it looks different from one situation to another.
for me i did an installation and update a lot of things that the sdk manager said to then i had this problem.
all i did was:
from file -> Invalidate caches/Restart
(a dialog will pop-up) choose Invalidate and restart.
after the restart is done. everything was fixed but i needed to create a new emulator and delete the old one.
(android studio 1.3.1)
(one professional must edit this to be more understandable)

Here everything was fine, but your machines also needs restart because some system files are changed, to sync them we have to restart the system.
This could be due to Android Studio version conflict of v3 and v4 especially when you import a project in android stdio v4 which was previously built in v3.
Here are the few things you need to do:
remove the .gradle and .idea folders from the main Application folder.
import the project in the android studio.
after the sync finished, it will ask you to update the android studio supported version.
click update.
done.
I had the exact same error message
Error running android: Gradle project sync failed. Please fix your project and try again
Steps to solve:
Close Android Studio.
Remove the .gradle and .idea folders from the Application folder.
Open Android studio with your project.
After these steps android studio gradle will sync and download the required files to run the project (don't forget to disable offline mode).
I got this error going from Gradle 3.5.3 to 5.4.1 (Android Studio prompted and I clicked "Upgrade".)
Gradle proceeded to upgrade but yielded some errors such as:
ONFIGURE SUCCESSFUL in 1m 27s
ERROR: The Android Gradle plugin supports only Crashlytics Gradle plugin version 1.25.4 and higher.
The following dependencies do not satisfy the required version:
root project 'Android%20App' -> io.fabric.tools:gradle:1.25.1
Update plugins
Affected Modules: app
INFO: API 'variant.getExternalNativeBuildTasks()' is obsolete and has been replaced with 'variant.getExternalNativeBuildProviders()'.
It will be removed at the end of 2019.
For more information, see https://d.android.com/r/tools/task-configuration-avoidance.
To determine what is calling variant.getExternalNativeBuildTasks(), use -Pandroid.debug.obsoleteApi=true on the command line to display more information.
Affected Modules: app
INFO: The specified Android SDK Build Tools version (27.0.3) is ignored, as it is below the minimum supported version (28.0.3) for Android Gradle Plugin 3.5.3.
Android SDK Build Tools 28.0.3 will be used.
To suppress this warning, remove "buildToolsVersion '27.0.3'" from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.
Install Build Tools 28.0.3, update version in build file and sync project
Affected Modules: app
The thing that fixed it was opening Settings --> Appearance & Behavior --> System Settings --> Android SDK and I then selected some recent versions of Android SDK like 8, 9, and 10. (I had only had 5.1, 6.0, and Android N Preview installed.)
Once that's installed, I had to modify my build.gradle file for my Module: app
Removed buildToolsVersion '27.0.3'
Then I clicked the "Sync Project with Gradle Files" button on the toolbar. The Sync output window offered an option to "Update Plugins" and once I clicked through that everything seemed to work. For good measure I again clicked "Sync Project with Gradle Files" followed by Build --> Clean Project, and finally I was able to run my project again.
Resolution is simple. Open the "Android SDK Manager", update all packages and then restart your Android Studio. After that you project should compile without any issues.
It took me some time to resolve this.
Updated SDK Build-Tool [Didn't help]
Updated CMake [Didn't help]
Updated Android SDK Platform-Tools [Didn't help]
Updated Android SDK Tools [Didn't help]
Updated NDK [Problem solved]
There was a reason, I didn't want to update NDK. When all else failed, I updated NDK and that did the trick.
If your got timeout, Check Gradle Scripts -> gradle.properties in Android Studio, I found that I do have set a socket proxy in Android Studio settings, but in this gradle.properties file, my proxy became to http, so I just removed this http proxy setting lines, and finally works.
I got this problem on Android studio, there in either sync or build square were this link like blue text about this issue, press that button and it download something that fix this problem
I ran into the same issue, but then did the following, and my issue was resolved:
updated Gradle
installed the latest version of Android studio (mine was out of date)
And that solved my problem.
Note: It also helped me to click on the event log, because it has more detailed info about errors. https://developer.android.com/studio/releases/gradle-plugin#updating-plugin also has great info.
I've installed Android SDK Command-Line Tools from SDK Manager and after, juste Sync again and all is worked well.
it was hard to solve but i did it
look go to
C:\Users(user name)
delete .gradle file
its you didn't see it it may be in hidden files so if you use windows 7
right click then click on properties and click on hidden to be not checked
then the file will appear then delete it
i hope this works
It could be that you are using gradle in offline mode.
To uncheck it go to File > Settings > Gradle, uncheck the Offline Work checkbox, and click Apply
Make sure you have internet connection and sync the project again.
Its because the gradle is not synced because of many reasons.
Go to project folder and remove .gradle folder and start sync. It will work
Apparently, some platforms could be missing. This is how I solved the problem:
Do you see an error message that is shown at the bottom of your Android Studio window? It could be a smaller window on the bottom right also.., which looks like:
Now, Click on that blue link, do as the dialog boxes say (if any)...
That solved the problem. Hope it helps...
Download grade files from this url and extract all in a folder:
 https://gradle.org/releases
Open file -> Setting in windows OS or Preferences in mac OS and in "Build, Execution, Deployment"
Click on "Gradle"
Check “Use local cradle distribution” and give that extracted folder path.
Run gradle.bat for Windows OS and gradle file for mac OS in that folder.
Then check “Offline work”.
"your extracted folder path"/gradle-4.10.2/bin/.gradle (for version 4.1.2 you can set your version)
Press OK and enjoy it.
I had the exact same error message
Error running android: Gradle project sync failed. Please fix your project and try again
, but if none of the above fixes your error, then I would highly suggest for you to check your syntax inside the AndroidManifest.xml file.
That fixed if for me. I don't understand why the error-message is so misleading, since it had nothing to do with the build gradle directly.
Please also see this SO-answer here, which has lead many of us in the right direction.
It was yelling at me about a line in my xml file (which was perfectly valid and never had problems the entire time I've worked on the project). I deleted the line and even after running again and cleaning and rebuilding it kept yelling at me about the completely blank line. I restarted android studio and removed the .gradle folder and it finally worked. Hopefully someone in my shoes that had all of the other answers in this thread fail them will see this answer and save a few hours.
I had this problem (clicked a prompt to "sync with gradle" on my perfectly valid and working project and it killed everything) and I researched for hours trying to figure out how to fix this, including this thread among many others. I finally found my solution, so hopefully, it'll help somebody (and hopefully they fix this terrible system)
I encountered this in a unique situation: had refactored the word "time" to "distance" for one of my variables. And when I did the refactor, accidentally had it change the name of one of my gradle dependencies / implementations.
This is a rare cause of the error, but a possibility. So make sure all your dependencies are properly implemented in build.gradle
Delete .gradle folder(root directory) and build folder(project directory) and then invalidate caches/restart android studio, run your project again hopefully it will work. It might take some time for the background tasks. In some countries, you may need to turn on the VPN to download.

Android Studio project files not showing up

I have a library project in Android Studio that has been working fine, but today I went to work on it and all of the files are missing except for a few git files. The folders/files are there when I look in the project's folder on my hard drive, they just aren't displaying in Android Studio. Here is a screenshot:
I tried reinstalling and updating Android Studio, but it didn't work. Any ideas as to what is going on here? How can I fix it?
Try Import Project... and navigate to your project. Select build.gradle file.
Be sure to wait for a while, so that android studios can load all your stuff. Sometimes a restart will help, but since you reinstalled it, that shouldn't be the problem.
Go to File > Project Structure > Project Settings > Modules.
Click on the green colored + and add new module. select Application module and set the content root to your project module.
Click next and then finish.
This should do the trick and the complete project structure will appear. It worked for me.
I had to Sync Project with Gradle Files in Android Studio to get my files back after they disappeared in Android Studio's Project window.
Go to
File > Project Structure> click on + > then set it to android
Go to:
File > Sync Project with Gradle files.
It will show up all the files linked with the gradle.
You can reset the IDE configurations by removing the configurations folder manually.
First close your project in Android Studio
In the project's root folder run:
rm -r .idea
Open your project again.
In my case i have a slash in the subproject
settings.gradle
As an example, this did not work:
include ":somedir/library"
But changing it to this fixed it:
include ":somedir-library"
project(":somedir-library").projectDir = new File(settingsDir, "somedir/library")
In my case, it was because of the NDK version
In my case only File -> Invalidate Caches / Restart... works.

Android Studio HoloCircularProgressBar Library

I am trying to add the project https://github.com/passsy/android-HoloCircularProgressBar as a library to my project using android studio. I have added the project as a module and loaded it into the build.gradle file and added the dependency as well.
dependency {
compile project(':HoloCircularProgressBar')
}
No matter what it won't be able to find the attr 'cicularProgressBarStyle' and even in the xml it says unable to locate class file.
Would appreciate any help on this matter.
Thank you.
To import this plugin in Android Studio, complete the following steps:
Download the latest version of the plugin and extract the library directory
(rename it if you want - I've called mine circularProgressBar)
Create a new directory called libraries at the root of your project in Android Studio
Put the previously extracted library directory into into the new libraries directory
Go to your settings.gradle (also at the root of your project) and add the following:
include ':libraries:circularProgressBar'
Now go to File > Project Structure, select your module and click on the Dependencies tab, then click '+' and select 'Module Dependency'. You'll be prompted to select the holoCircularProgressBarModule. Select it and click OK.
Do a Gradle Sync and the project should be successfully imported.
This was completed using Android Studio 0.5.8
