Steps

1. Generate key

2. Modify the android/app/build.gradle file

3. Modify android/gradle.properties

4. CD android && ./gradlew assembleRelease

Enter a directory and execute

$ keytool-genkey-v-keystore my -release-key.keystore- alias my -key- alias -keyalg rsa-keysize 2048 -validity 10000

The resulting file will be copied to the project directory/android/app under the current directory.

Configure Build.gradle

Signingconfigs {

Release {

StoreFile file (myapp_release_store_file)

Storepassword Myapp_release_store_password

Keyalias Myapp_release_key_alias

Keypassword Myapp_release_key_password

}

}

Buildtypes {
Release {
Minifyenabled Enableproguardinreleasebuilds
Proguardfiles getdefaultproguardfile ("Proguard-android.txt"), "Proguard-rules.pro"
Signingconfig Signingconfigs.release
}
}

And then modify the Android/gradle.properties

Add the following content

Myapp_release_store_file=my-release-key.keystore

Myapp_release_key_alias=my-key-alias

myapp_release_store_password=123456// The password I tested was 123456.

myapp_release_key_password=123456
