Tutorial Android Studio: Fix error "Keystore file not set for signing config releaseConfig"

[AndnixSH]

I got this error, trying to build APK from an open source project

Execution failed for task ':app:validateSigningDebug'.
> Keystore file not set for signing config releaseConfig

Unless this is for private use, or you are just lazy to generate keystore, just REMOVE the following codes from /app/build.gradle.

Properties props = new Properties()
def propFile = file('../signing.properties')
if (propFile.canRead()) {
    props.load(new FileInputStream(propFile))
    if (props != null &&
            props.containsKey('SIGN_FILE') && props.containsKey('SIGN_PASSWORD') &&
            props.containsKey('KEY_ALIAS') && props.containsKey('KEY_PASSWORD')) {
        android.signingConfigs.releaseConfig.storeFile = file(props['SIGN_FILE'])
        android.signingConfigs.releaseConfig.storePassword = props['SIGN_PASSWORD']
        android.signingConfigs.releaseConfig.keyAlias = props['KEY_ALIAS']
        android.signingConfigs.releaseConfig.keyPassword = props['KEY_PASSWORD']
    } else {
        println 'release build not found signing properties'
        android.buildTypes.release.signingConfig = null
    }
} else {
    println 'release build not found signing file'
    android.buildTypes.release.signingConfig = null
}

buildTypes {
    debug {
        versionNameSuffix "-debug"
        if (signingConfigs.releaseConfig != null) {
            signingConfig signingConfigs.releaseConfig
        }
    }
    release {
        minifyEnabled false
        if (signingConfigs.releaseConfig != null) {
            signingConfig signingConfigs.releaseConfig
        }
    }
}

You should be good to go
