5. Click on Run, next click on Continue Anyway, then click on Yes then in the dialog .
6. Then fill these details:
7. Now go to Build Types and follow this image:
8. And click ok.

Now when you run the commands to get the hash through AppSignatureHelper Class, that key will be your production key.

Answer 2

You must add release app string hash to message sent from server because release hash different from debug hash SMS retriever verify

Answer 3

Few days ago, I had the same problem. Actually there is nothing wrong in your code. When you run your app and create hash, it create hash only for device specific. When your generate signed apk and create hash ( using log ), then this hash is only for release but not for production. In case of production, you have to install app from play store and check hash ( using logs ) and that hash will use for all users.

Hope it will help you

Answer 4

I had the same problem by using

SMSRETRIEVERAPI

I got the otp for debug build but when I pushed that to playstore I would not auto read the otp.Actually it will generate the hashkey based on your application build variants type.So Inorder to auto read your otp you will change the your hashkey in your server that will be generated in release mode.

So find the Hashkey in release mode and update it in your server.Thats it you will get It.

1. First download app signed certificate der from your play console account.

2. Then convert it to yourkeystore.keystore with keystore extension using this command:

   keytool -import -alias your_alias -keystore file_name_created.keystore -file certificate.der

3. Then create string hash using the created keystore.
   Use this file bash to create hash string:

Answer 6

First download your app signing certificate .der file then convert to .jks file by this command

keytool -import -alias your_alias -keystore file_name_created -file certificate.der

then new .jks file created

then use this command for generate hash for your release

keytool -exportcert -alias your_alias -keystore certificate.jks | xxd -p | tr -d "[:space:]" | echo -n  app_package_name `cat` | sha256sum | tr -d "[:space:]-" | xxd -r -p | base64 | cut -c1-11

then create hash string and it will work on play store app.
