I'm trying to generate a SHA-1 for a Flutter app, for Android studio to support Google Sign in, but I don't know how to do that, I saw some posts that indicate to run a command, but there I need a jks file I guess, and flutter doesn't create that.

Could someone help me?

TERMINAL

Go to the project folder in the terminal.

Mac keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

Windows keytool -list -v -keystore "\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

Linux keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

GUI Android Studio.

  1. Select android/app/build.gradle file and on the right top corner click "Open for Editing in Android Studio"

enter image description here

  1. Open Gradle panel and double click on "SigninReport",

see Android studio Gradle Tab

enter image description here

  1. That's it! If you use Firebase - add these 2 keys there. You should add both keys, otherwise, without the release key, Google login will not work on the devices.

I cannot see the "Open for Editing in Android Studio" option
In this case on mac you can use keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android
In my case it was "import Gradle project" for my Flutter app. But had to wait for indexing a bit.
If you cannot see the "Open in Android Studio" option, close your Flutter project. In Android Studio -> Open the android module of the flutter project in Android Studio from its path.
The Gradle Console tab has been replaced by "Build" in Android Studio 3.1, accessible from View -> Tool Windows -> Build.

This is the easiest way-

  1. Open Android Studio

  2. Open Project

  3. Reveal android folder

  4. Right click "gradlew" file and select Open in Terminal -

Open in Terminal

  1. Go to the terminal view and paste: gradlew signingReport or ./gradlew signingReport if you're using PowerShell or a Unix-based system like mac.

Paste

  1. Press enter and scroll to "Variant: debug" to get the SHA1 key

Scroll to key

  1. Copy and use wherever you need it, Good Luck!

it takes time for configuring process
For those of us that get an error about JAVA_HOME not being set, I updated my environment variables and added a System variable named JAVA_HOME set to C:\Program Files\Android\Android Studio\jre. Then I updated my Path variable and added %JAVA_HOME%\bin. Then this answer worked for me.
This one give me the debug key. How can I get the release key. So that I can use it for production.
@WilliamHerrmann - I got the JAVA_HOME error, too, but Android Studio told me to run it using ctrl+return which runs it in the IDE instead of the terminal - that worked for me, too.
for WINDOWS use ./gradlew signingReport if your using powershell

You won't find a gradle window view in flutter project, so here is a solution for that.. In command prompt navigate to bin folder of jdk and run this command

keytool -list -v -keystore "C:\Users\yourusernamehere\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

change user name in path

for mac command is keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android
'keytool' is not recognized as an internal or external command, operable program or batch file.
thank you rishab 👍 the ./gradlew signingReport for the life of me didn't work for me on my flutter project and even the gradle window in android studio
131

I partially agree with Rishab answer, but what we can do is

and this approach works with all flutter/React-native/Android ....

Navigate to Android folder inside project, there is gradlew file. so we can use this like :

gradlew signingReport

in Mac

./gradlew signingReport

in my case i use it like :

D:\flutter\flutter_app\android>gradlew signingReport

Project Architecture is :

Easyest solution by far ! once you will have enter ./gradlew signinReport, the SH1 key will be prompted
I did the following: cd android ./gradlew signingReport But the details of the ~/user/debug.keystore were printed. Shall we not use the debug.keystore inside the folder instead?? or what??
./gradlew signingReport works for windows too.

so if you are using an android studio or VS code it's work both of them

=> Open Terminal

=> cd android

enter image description here

=> signingReport

enter image description here

and the final output like this as given in the image below choice your SSH key in at the place of here is your SSH key

enter image description here

in the above output, image is shown in dummy data I change some of the fields just because of security purpose

Edit: for mac

./gradlew signingReport

For Android Studio 4.2 and Flutter 2.2

Windows:

Open your project open android > gradlew > right click on it and click open in terminal

Like below:

enter image description here

My Project Directory: D:\AndroidStudioProjects\WowTalentNew\android>gradlew

open this in terminal.

After build finished execute this

D:\AndroidStudioProjects\YourProjectDirectory\android>gradlew signinReport

After that you will see the SHA keys

in Linux instead of just type gradlew we write ./gradlew to build. and to get SHA-1 we write: Terminal> ./gradlew signinReport and we could just build and get SHA-1 key with just one command: Terminal> ./gradlew signinReport

I hope it clears everything, happy coding!

To generate SHA-1 for a Flutter :

1. Locate your android directory inside the console

E:\<appname>\android>

2. After locating to the android folder run this command

./gradlew signingReport

If this won't work and opens a daemon terminal

1. Type signingReport in daemon terminal

daemon> signingReport

This would be taking a bit long time to generate your first SHA-1 as it would be checking for all the firebase dependencies and after that over it generate the SHA-1.

It works, however it generated a debug SHA. How can I generate a release SHA?
I could find a release SHA-1 by this video youtube.com/watch?v=oyJNP3-N838&ab_channel=FlutterMapp

Check this Authenticating Your Client  |  Google APIs for Android

To get the debug certificate fingerprint:

for Mac or Linux

keytool -list -v \ -alias androiddebugkey -keystore ~/.android/debug.keystore

for Windows

keytool -list -v \ -alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore

The default password for the debug keystore is android.

The keytool then prints the fingerprint to the terminal.

1. First Methord just run the below command

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

2. Second Methord

1. Left side open the android folder not the whole project in android studio.

2. Right Side open the file android/app/Tasks/anroid/signingReport

Final this process will take some time and it might be of 5-10 minutes so be patient

You can generate it even from terminal. Following is for the release mode:

keytool -list -v -keystore keystore_location -alias alias_name

example : 

keytool -list -v -keystore /home/user/key.jks -alias alias_name

I'm using a Mac and Android Studio Dolphin 2021.3.1 Patch 1.

None of the answers with visual directions worked for me because when I pressed the gradle/elephant in the upper right hand corner of Android studio, there were only 2 paths MyPojectName/app. Everyone else's has more paths underneath however mines only has 2.

When I pressed the elephant (Execute Gradle Task) and I typed in signingReport nada. I looked through the list but it wasn't there.

When I opened Terminal in Android studio and entered gradlew signingReport nothing found. Then I tried ./gradlew signingReport and still nothing.

Long story short it only took 2 easy steps to find the keys. I first followed this answer:

1- Android Studio/Preferences/Build,Execution,Deployment/Build Tools/Gradle. In the right panel click the Gradle JDK dropdown then select Download JDK

2- After that finished, while in Android Studio I opened Terminal

enter image description here

In there I followed R7G's answer (his answer didn't work at first without step 1) and entered this into terminal (bottom of Android Studio):

bash ./gradlew signingreport

And like that, both keys appeared

enter image description here

Another option is to add Gradle either using Homebrew

brew install gradle

or install gradle manually

To find where gradle is located on mac

Another option is to run gradle wrapper and follow the prompts

First, check which Keystore is being used by your project in

enter image description here

Then use the below command

 keytool -list -v -alias mstoreappsemoAlias -keystore  fluxstorepro/android/app/mstoresemoFile.keystore

and if you want to generate a hash key for Facebook then use the below command

 keytool -exportcert -alias mstoreappsemoAlias -keystore fluxstorepro/android/app/mstoresemoFile.keystore | openssl sha1 -binary | openssl base64

For Mac Users

If after typing ./gralew signingReport inside android folder gives you this error:

The operation couldn’t be completed. Unable to locate a Java Runtime.
Please visit http://www.java.com for information on installing Java.

Then follow this process:

  1. Run flutter doctor -v
  2. Now inside the Android toolchain copy the location after Java binary at:. It will be something like this: /Applications/Android Studio.app/Contents/jre/Contents/Home/bin/java
  3. Paste it in the project's root location and Replace the java at the end of the above location with keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android.

You are done, you will see the keys now.

I found that I needed to check the fingerprint in Google Play Console, since I have Google Play managed app signing.

The ones provided by gradlew did not work for me.

Note that you can put both in Firebase, but you only need one. I just added the SHA1 and Google Sign In began working.

Personally, I went to the terminal then navigated to C:\Program Files\Java\jdk-14.0.2\bin (navigate to your java bin folder).

Next, I ran this command and it worked: keytool -list -v -keystore "%USERPROFILE%.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android
