how to add value to build.gradle?

Question

Is there a way to do with shared preference? or,

Add a database column value to build.gradle?

buildConfigField "String", "secretKey", "\"here should be the value i want\""

Answer 1

In the root directory create a file, for ex: apikey.properties

SECRET_KEY=YOUR_SECRET_KEY

In your build.gradle to read the apikey.properties

def apikeyPropertiesFile = rootProject.file("apikey.properties")
def apikeyProperties = new Properties()
apikeyProperties.load(new FileInputStream(apikeyPropertiesFile))

android {
  defaultConfig { 
    buildConfigField("String", "SECRET_KEY", apikeyProperties['SECRET_KEY'])
  }
}

You can access the field in your with the BuildConfig object.

String secretKey = BuildConfig.SECRET_KEY;
