Generate SHA-1 for Flutter/React-Native/Android-Native app

Question

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?

Solution 1

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"

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

see Android studio Gradle Tab

3. 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.

Solution 2

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 -

5. Go to the terminal view and paste: gradlew signingReport

(edit based on Venkat D. suggestion below: on unix-based systems like mac, you need to specify the current directory like this- ./gradlew signingReport)

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

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

Solution 3

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

Solution 4

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 :

Solution 5

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

=> Open Terminal

=> cd android

=> signingReport

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

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

Worth mentioning that on unix-based systems like mac, you need to specify the current directory like ./gradlew signingReport

The Only Detailed Solution that is working for my flutter project. Thank you a lot <3

[Dani]

I cannot see the "Open for Editing in Android Studio" option

[EslamWael74]

./gradlew signingReport

[G.Busato]

Easyest solution by far ! once you will have enter ./gradlew signinReport, the SH1 key will be prompted

[awaik]

In this case on mac you can use keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

[awaik]

for mac command is 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.

[Zephania Mwando]

Worked like magic, only I had a hard time figuring out on the second step opening Gradle yet it is on the right android studio by default. I hope that helps someone.

[August Kimo]

the ./isn't needed for me in Windows. This works using gradlew signingReport

[devu mani]

Also, you can directly open the android(project name -> android) as an android project

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.

[NullByte08]

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.

@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 ubuntu - android studio correct command or usage; right cicl to project/android/gradlew "run gradlew option> after that in below terminal screen, press up keyword and use; /bin/bash "your android studio folders path"/AndroidStudioProjects/project_folder/android/gradlew signingReport

[malik kurosaki]

work for me ,flutter on vscode "cd android && ./gradlew signinReport"

'keytool' is not recognized as an internal or external command, operable program or batch file.

This solved the API exception PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null, null)

[mohannadalnono]

that's work, please add linux command to your answer so it'll benefit more people: 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

Why my key is much longer than others. I also would like to achieve auth in flutter with microsoft, stackoverflow.com/questions/71338563/…
