'No key with alias found in keystore

Our android project consists of mobile and wear app ( wear app is under development) and we are trying to release the mobile app. When we try to generate signed apk we get this follow message :

Error:Execution failed for task ':wear:packageRelease'.
> com.android.ide.common.signing.KeytoolException: Failed to read key
toyanathpatro from store "/home/adventure/toyanath_patro_key/toyanath_patro_key":
No key with alias 'toyanathpatro' found in keystore /home/adventure/toyanath_patro_key/toyanath_patro_key

As it reads it says failed task for :wear:packageRelease where in reality we are selecting just the mobile while choosing for signing the apk.

Can anyone point out my blunder ? Thanks in advance.

The problem seems to be with the wrongly spelled key alias In my case the alias should have been toyanath patro where I wrongly tried to use toyanathpatro . So the best suggestion would be:

Don't use space or invisible character in the key alias. as far as possible
There is a small selection button (3 horizontal dots) on the right side of key alias editable field. Use that button to find the alias which resides in that signature file.

In your build.gradle you have defined a signing config that it's pointing to a keystore that it's not in your code base.

Something similar to this.

android {
    ...
    buildTypes {
        release {
            signingConfig signingConfigs.staging
            ...
        }
    }
    signingConfigs {
        defaultSignature {
            keyAlias 'default'
            keyPassword 'password'
            storeFile file('default-keystore.jks')
            storePassword 'password'
        }
    }
}

In my case android studio by default create alias 'key0' and it is the only alias in the file. My fast solution: Create new key file from android studio with alias that You want. Use that new created file with "Generated Signed APK". If all goes well You could run app with properties set up in "Project Structure".

After generating keystore with-

keytool -genkeypair -v -keystore my-key.keystore -alias my-alias -keyalg RSA - 
keysize 2048 -validity 10000

You should use exact name of alias in gradle.properties :-

MYAPP_UPLOAD_STORE_FILE=my-key.keystore
MYAPP_UPLOAD_KEY_ALIAS=my-alias <------this name
MYAPP_UPLOAD_STORE_PASSWORD=***
MYAPP_UPLOAD_KEY_PASSWORD=***

I had a sticky configuration which I could not get rid of. Even though I had changed the alias in the signing configuration window, it kept giving me the error "Could not find alias" with the original (wrong) alias that I first entered. I searched manually and found a file on path...

[project]/android/app/build/intermediates/signing_config/release/out/signing-config.json

...which contained the original (wrong) alias I first entered. Deleted the file and built/signed the app again. Hope it helps someone.

Build -> Rebuild project

It seems old key names are cached.

Solution 7:^[7]

If you had the .Jks file before then you can get alias name by typing this command

keytool -v -list -keystore .jks

keytool -v -list -keystore .keystore

then you will have to type the password and you will get the alias name by that alias name you can create your signed release file easily.

Solution 8:^[8]

Click Build>Edit library and dependencies .

Then click plus button in signing tab. Key Alias is as same as Alias Key while generating signed apk build.

Solution 9:^[9]

I initially used key0 for building. It failed with 'Errors while building APK'. Next time, I changed it to 'key1' to work and it worked.

Solution 10:^[10]

Do not use capital keys for password. It's worked for me.

Solution 11:^[11]

For generating .jks keys ,

keytool -genkey -alias myKeyStore -keyalg RSA -keystore "C:\apk\fastmoneyv1.jks"

Solution 12:^[12]

If you are use this code when creating key

" keytool -genkey -v -keystore ~/upload-keystore.jks -keyalg RSA -keysize 2048 -validity 10000 -alias upload"

You have to update "keyAlias" property from key.properties

from: keyAlias=key

to: keyAlias=upload

Solution 13:^[13]

in my case i had my keystore files already generated. I was updating my app and when i generated signed apk, i was creating new key_alias. Instead i choosed existing key alias from my keystore files and it's been resolved :)

Solution 14:^[14]

My problem was that I lost my keys and when I contacted google for making a new key I made a new one with an alias name that I don't know so to solve this in your root android project cd app and paste this command keytool -v -list -keystore yourkeystore.jks don't forget to replace the yourkeystore.jks with your key you will get output we need only the Alias name copy this alias name and past it in your key.properties file like this

storePassword=YourPassword
keyPassword=YourPassword
keyAlias=AliasNameCopiedFromLastStep
storeFile=KeyStorePath
