i have an issue with building appbundle with flutter

i'm trying to prepare my app for publishing to play store, bur while i'm creating the app bundle, this error shows up too many times, i was recreate the keystore but it's failed again,
i want to mention that when i setup keystore it's asks me for keystore password just without keypass
A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
[ ]
> Failed to read key key from store "/Users/ahd/key.jks": Invalid keystore format

I had this issue and it was because of the version of Java I was using. I used the keytool within Android Studio to generate the keystore instead and this fixed the issue for me.
Run flutter doctor -v and look for the "Java binary at:" entry. Then use this path swapping 'java' for 'keytool' to generate your keystore. For example
/Applications/Android\ Studio.app/Contents/jre/jdk/Contents/Home/bin/keytool -genkey -v -keystore ~/key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias key
In my case I also followed the recommendation that popped up at the end of this to migrate to PKCS12 (once again using the keytool in Android Studio).

xamarin -keystore and apk have sha1 is different

I have old Xamarin android project. I made small changes and changed target to android x. The customer sent me a keystore file with password and alias. Now I need to sign and publish the package in google play. But I am getting the error your fingerprint does not match:
-need "Sha1Need"
-current "Sha1Other"
I check my key file with command:
keytool -list -v -keystore "my.keystore" -alias key -storepass mypass -keypass mypass
I get result value "Sha1Need".
Than I checking my apk with command:
keytool -printcert -jarfile my.apk
I get value "Sha1Other". How is it possible? And how can I fix this?
I use this code in my .csprj file:
<AndroidSigningKeyStore>app.keystore</AndroidSigningKeyStore>
<AndroidSigningStorePass>mypass</AndroidSigningStorePass>
<AndroidSigningKeyAlias>alias</AndroidSigningKeyAlias>
<AndroidSigningKeyPass>mypass</AndroidSigningKeyPass>
--UPDATED--
This was a problem on the customer's side. He changed the password on the key several times, and one of the options worked.

Cannot see google maps on android when I upload it for release (works in debug), trying to get SHA1 from my created keystore

(Mac)
I created a keystore with alias and password with the same name (projectOne) and when I try to get the SHA1 from that created keystore and put it on my created google console maps I have trouble getting the SHA1 out.
I type this in the terminal but it does not let me access the keystore.
keytool -list -v -keystore ~/.android/ projectOne.keystore -alias projectOne
It says this (roughly translated):
Invalid option/Unauthorized: projectOne.keystore
Now I use the SHA for debug:
keytool -list -v -keystore ~/.local/share/Xamarin/Mono\ for\ Android/debug.keystore -alias androiddebugkey -storepass android -keypass android
And this does not work when I try to "release" it. So I assume I have to get the SHA1 from my own created keystore but as I mentioned above. It says it is an invalid option/Unauthorized option.

Based from this documentation you need to first find the .keystore file that your .apk was signed with. The keystore used will depend on if your app's .apk package was created as a debug build, or if it was packaged with a different .keystore file.
For builds that you have signed with your projectOne.keystore file, you need to substitute your own values for the .keystore file, keystore password, and alias name from when you created the keystore file.
You can follow these tutorial and forum which suggested to verify that the alias or password you use is correct.

How to obtain Signing certificate fingerprint (SHA1) for OAuth 2.0 on Android?

I'm trying to register my android app following the steps in https://developers.google.com/console/help/#installed_applications which leads me to follow
http://developer.android.com/tools/publishing/app-signing.html.
However, I'm not sure how to get the signing certificate fingerprint (SHA1).
I first used the Eclipse ADT plugin to export and create the keystore/key.
Then, I tried doing keytool -list keystore mykeystore.keystore and it gives me a MD5 Certificate fingerprint. Do I need to redo the signing (meaning I can't use the eclipse export wizard)?
Can I use a debug certificate first?

Start an export process to create an apk for your app and use your production key. The very last page displays both your SHA1 and MD5 certificate fingerprints

I know this question has been answered but this is how I found my signature for the default keystore. In Eclipse, if you go to Windows -> Preferences -> Android -> Build

I think this will work perfectly. I used the same:
For Android Studio:
Click on Build > Generate Signed APK.
You will get a message box, just click OK.
Now there will be another window just copy Key Store Path.
Now open a command prompt and go to C:\Program
Files\Java\jdk1.6.0_39\bin> (or any installed jdk version).
Type keytool -list -v -keystore and then paste your Key Store
Path (Eg. C:\Program Files\Java\jdk1.6.0_39\bin>keytool -list -v
-keystore "E:\My Projects \Android\android studio\signed apks\Hello World\HelloWorld.jks").
Now it will Ask Key Store Password, provide yours and press Enter to get your SHA1 and MD5 Certificate keys.

If you are using Mac or even Linux, just copy and paste this onto the Terminal application and you will get the SHA1 key immediately. No need to change anything.
keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android
Example output:
Alias name: androiddebugkey
Creation date: 17 Feb 12
Entry type: PrivateKeyEntry
Certificate chain length: 1
Certificate[1]:
Owner: CN=Android Debug, O=Android, C=US
Issuer: CN=Android Debug, O=Android, C=US
Serial number: 4f3dfc69
Valid from: Fri Feb 17 15:06:17 SGT 2012 until: Sun Feb 09 15:06:17 SGT 2042
Certificate fingerprints:
MD5: 11:10:11:11:11:11:11:11:11:11:11:11:11:11:11:11
SHA1: 11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:11:01:11
Signature algorithm name: SHA1withRSA
Version: 3

use this in the command line
c:\Program Files\Java\jdk1.6.25\bin>keytool -list -v -keystore c:\you_key_here.key

Open terminal (in Unix, in MAC), (cmd in Windows) and cd to this (your java) path:
C:\Program Files\Java\jdk1.6.0_43\bin>
Run this command:
keytool -list -v -keystore C:\Users\leon\.android\debug.keystore -alias androiddebugkey -storepass android -keypass android
Just change the path to debug.keystore and you will get both MD5 and SHA-1 fingerprints.

keytool -list -v -keystore "keyStoreName"
Run this command from the directory where the keystore of your app exists.

In Android Studio, follow these steps:
Click Gradle properties menu at right side of your android studio IDE.
Expand Task tree.
Click on signingReport
You can see your SHA1 at the bottom console

See if you want to use Google Map at that time you need MD5 fingerprint for generating api kay for using google map in your android application.
Keytool command generated MD5 fingerprint if you use JDK 1.6 and it generates SHA1 fingerprint if you use JDK 1.7.
So the thing is that if you want to sign your application for publishing then read this.
And if you want to use google-map read this.

If you are using IntelliJ (12+?), go to menu Build/Generate signed Api
After filling a popup, get the data in the field "key store path" (e.g. C:\Users\user\Documents\store\store)
And run in a command line:
>keytool -list -v -keystore "C:\Users\user\Documents\store\store"
....
MD5: 11:C5:09:73:50:A4:E5:71:A2:26:13:E0:7B:CD:DD:6B
--> SHA1: 07:0B:0E:E8:F7:22:59:72:6A:1C:68:05:05:CF:2E:6F:59:43:48:99
SHA256: E6:CE:DA:37:C1:18:43:C1:A3:F0:9E:8F:1A:C2:69:AF:E6:41:F7:C0:18:
1D:1D:55:5D:F0:52:6C:EE:77:84:A7
...
Good luck

If any one using the Android studio...
click: Build > Generate Signed in APK
Create a new key: this will generated ".jks" files
Use following command to read the data(SHA1 and other info):
$ keytool -list -v -keystore filename.jks

For those using OpenSSL you can retrieve the SHA1 fingerprint this way:
OpenSSL> dgst -sha1 my-release-key.keystore
Which would result in the following output:

I was so confusing first time, but I propose you final working solution for Windows:
1) Open cmd and go to your Java/jdk/bin directory (just press cd .. to go one folder back and cd NAME_FOLDER to go one folder forward), in my case, final folder: C:\Program Files\Java\jdk1.8.0_73\bin>
2) Now type this command keytool -list -v -keystore C:\Users\YOUR_WINDOWS_USER\.android\debug.keystore -alias androiddebugkey -storepass android -keypass android
As result you have to get something like this:

Here is my easy solution for this:
Click on Gradle button, you can find at the right side top. you will see all the gradle files. Now go to android, and double click on signingReport. Once the gradle build finishes, you see the SHA key. Check the below images for step by step guide.
Once you click on Gradle check the below images. Hope this helps someone.
STEP 1:
STEP 2:

If you are using Android Studio. You can get fastly the SHA1 certificate fingerprint (debug,release... all Build Types!!) through Gradle Tasks:
signingReport
SHA1 is shown in Messages Logs
Android Plugin (configured in the gradle app) creates a debug mode for default.
com.android.application
File route to keystore:
HOME/.android/debug.keystore
I recommend attach debug.keystore to build.gradle. To do this put a file debug.keystore to a app folder and then Add SigningConfigs in gradle app:
apply plugin: 'com.android.application'
android {
................
signingConfigs {
debug {
storeFile file("../app/debug.keystore")
storePassword "android"
keyAlias "androiddebugkey"
keyPassword "android"
}
release {
storeFile file("../app/debug.keystore")
storePassword "android"
keyAlias "androiddebugkey"
keyPassword "android"
}
}
........
}
Extra: If you want creates for release, put a file release.keystore to a app folder. (This example uses the same debug.keystore)

If you are using Android Studio. You don't need to generate a SHA1 fingerprint using cmd prompt. You just need to create a project with default Maps Activity of Android Studio.In the project you can get the fingerprint in google_maps_api.xml under Values folder. Hope this will help you. :)

Try this One:
Windows----preferences----Android--build---sh1 code copy from here

I think this will work perfectly. I used the same:
For Android Studio:
Click on Build > Generate Signed APK.
You will get a message box, just click OK.
Now there will be another window just copy Key Store Path.
Now open a command prompt and go to C:\Program Files\Java\jdk1.6.0_39\bin> (or any installed jdk version).
Type keytool -list -v -keystore and then paste your Key Store Path (Eg. C:\Program Files\Java\jdk1.6.0_39\bin>keytool -list -v -keystore "E:\My Projects \Android\android studio\signed apks\Hello World\HelloWorld.jks").
Now it will Ask Key Store Password, provide yours and press Enter to get your SHA1 and MD5 Certificate keys.
Now add this SHA1 key to the google developers console in credentials tab and also change the build variants in android studio to release mode.

Please Click on Gradle from Right side of Menu
Then Click on :app
Then Click android folder
Then SigningReport file name is exist there
Double click on that.
It Will start executing and in a while it will show you SHA-1 Code
Just copy the code.
And paste it where you need it

For those on mac looking for keytool. follow these steps:
Firstly make sure to install Java JDK
http://docs.oracle.com/javase/7/docs/webnotes/install/mac/mac-jdk.html
Then type this into command prompt:
/usr/libexec/java_home -v 1.7
it will spit out something like:
/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home
keytool is located in the same directory as javac. ie:
/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/bin
From bin directory you can use the keytool.

If you are on Mac/Linux, then you can get SHA1 fingerprint by writing following line in the terminal:
keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android
There are 2 things possible after this
It will ask you for the password
Just type
android
and press enter, you can find the SHA1 key in the output shown below.
It will ask you to download a suitable program (and some list will
be given)
Just type following in terminal
sudo apt install openjdk-8-jre-headless
and then again run following in terminal: keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android
This time, you will be led to step 1, where you need to just enter the password as
android
and you will get your SHA1 fingerprint below in the output.

Open your command prompt
Navigate working directory to 1.8.0/bin
paste keytool -list -v -alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore
Press enter if it ask you a password

If you want to obtain fingerprint-sha1 key from signing keystore.jks file
Run the following command from terminal:
keytool -list -v -keystore <.../path/keystore.jks>
Example
keytool -list -v -keystore /Users/Home/Projects/Keystore/myApp_keystore.jks
Enter keystore password:
Keystore type: JKS
Keystore provider: SUN
Your keystore contains 1 entry
Alias name:myApp_alias
Owner: CN=xxx, OU=xxx Dev, O=ZZZ, L=Dhaka, ST=Dhaka, C=BD
..........
Certificate fingerprints:
MD5: 12:10:11:12:11:11:11:11:11:11:33:11:11:11:11:11
SHA1: 11:44:11:11:55:11:17:11:11:66:11:11:88:11:11:77:11:11:01:11
.....................

Using portecle :
File > Open Keystore file
Enter Keystore password
Right click on alias name > Certificate details > SHA-1 Fingerprint

Easiest way to Get SHA-1 For Release and Debug mode android studio gradle. Check this

I wanted to post a notice to those that are having the same issue as me. I went through the steps to generate my debug SHA-1 and my release SHA-1. I was attempting to connect Google Sign-In API with my app.
I ran into the issue that the debug .apk would work fine, it would connect and authenticate with Google Sign-In. My release .apk would also work, when installed manually to the phone. When I posted my release .apk to the Google play store, my google Sign-in would not authenticate and I would get an issue!
For the longest time I couldn't figure it out, but I found that my app was being signed by google, i.e., the message on the top of the Developer console was showing: Google Play App Signing is enabled for this app.
I went to my Release Management tab, then scrolled down to App Signing, and found the SHA-1 there. After adding this to my code and on "firebase console" which I was using as the backend for Google Sign-in, everything seemed to work. It looks like my release keystore was getting replaced with the google signed certificate... I'm not really sure if this is what was happening, but it resolved my issue and allowed my Google Play Store release apk to correctly authenticate with the google sign in!

Step by step solution:
Open your command prompt or Terminal for Mac
Change directory to directory of the keytool file location. Change directory by using command cd <directory path>. (Note: if any directory name has space then add \ between the two words. Example cd /Applications/Android\ Studio.app//Contents/jre/jdk/Contents/Home/bin/)
To find the location of your keytool, you go to android studio..open your project. And go to
File>project Structure>SDK location..and find JDK location.
Run the keytool by this command:
keytool -list -v –keystore <your jks file path> (Note: if any directory name has space then add \ between the two words. example
keytool -list -v -keystore /Users/username/Desktop/tasmiah\ mobile/v3/jordanos.jks)
Command prompt you to key in the password.. so key in your password.. then you get the result

Here is tool for lazy coders:
1 add dependency:
compile 'com.vk:androidsdk:1.6.9'
2 add following lines somewhere in your activity/application:
String[] fingerprints = VKUtil.getCertificateFingerprint(this, getPackageName());
Log.d("SHA1", fingerprints[0]);
3 Open logcat and catch message.
4 Profit!

In latest version of Android Studio best way to get the SHA-1 key is form terminal. ,
open terminal in Android studio
Copy the
command( keytool -list -v -keystore ~/.android/debug.keystore -alias
androiddebugkey -storepass android -keypass android)
Paster it on terminal and press the enter key

sign android apk with existing .keystore

I'm using Eclipse, and except for the default keystore path specified in windows->preferences->android->build, I didn't specify any other customized keystore path in eclipse.
I have the debug.keystore in two locations. one is in the default path, and the other say c:\customised_path.
however, when i wanted to generate the cert:
keytool -genkey -v -keystore debug.keystore -alias androiddebugkey -keyalg RSA -keysize 2048 -validity 20000
it'll generate the debug.keystore in the java\bin folder.
and if i try:
C:\Java\jdk1.6.0_25\bin>keytool -genkey -v -keystore C:\default_path\.android\d
ebug.keystore
keytool error: java.io.IOException: Invalid keystore format

it'll gimme the same error to generate the key in the customized path too.
i have debug.keystore in both folders still i'll have this:
C:\Java\jdk1.6.0_25\bin>keytool -list
keytool error: java.lang.Exception: Keystore file does not exist: C:\customiesed_path\.keystore
and
C:\Java\jdk1.6.0_25\bin>keytool -list -keystore C:\the_default_path_specified_in_eclipse.keystore
keytool error: java.lang.Exception: Keystore file does not exist: C:\default_path
Eclipse is using the .keystore in the default folder to sign the apk, and i have the .keystore in the default folder, but it just doesn't allow me to sign it and gives me annoying error when I try to run my application.
Could somebody help here please?

Bingo! problem solved! it seems that the .keystore is somehow changed and after I re-download it, it works again.
I re-downloaded the .keystore that I need to use and run eclipse again. Now everything works normal. So next time someone has problems generating apk file using an existing key, please take into consideration "run" in eclipse not from cmd as well as download a new keystore.
One more thing: signing in debug mode is different from release mode! Eclipse uses "run" to sign in debug mode. Using command line won't work because they're simply for release.
