How to generate APK from an Expokit project?

Question

I was with an Expo project, but due to the need to apply payment methods I had to eject the project to have the folders /android and /Ios to edit them directly. I decided to use React-Native-iap, so I ejected to an Expokit project, as it is recommended by the Expo documentation as it continues to use Expo properties, as opposed to a full ejection. So... I did the edits right, but how do I generate the app apk? Since 'expo build:android' does not work in this type of project.

Answer 1

1 - Put Keystore on android/app

2 - Change one of the files : ~/. Gradle/Gradle.properties or android/Gradle.properties by changing to your Keystore configs:

MYAPP_RELEASE_STORE_FILE=minha_key.keystore
MYAPP_RELEASE_KEY_ALIAS=minha_key-alias
MYAPP_RELEASE_STORE_PASSWORD=*****
MYAPP_RELEASE_KEY_PASSWORD=*****

3 - Edit android/app/build.Radle and add the variables above:

...
android {
    ...
    defaultConfig { ... }
    signingConfigs {
        release {
            if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
                storeFile file(MYAPP_RELEASE_STORE_FILE)
                storePassword MYAPP_RELEASE_STORE_PASSWORD
                keyAlias MYAPP_RELEASE_KEY_ALIAS
                keyPassword MYAPP_RELEASE_KEY_PASSWORD
            }
        }
    }
    buildTypes {
        release {
            ...
            signingConfig signingConfigs.release
        }
    }
}
...

4 - To generate :

$ cd android
$ ./gradlew assembleRelease

APK will be on : android/app/build/outputs/apk/release/app-release.apk
