How to use a property from gradle.properties inside android activity?

Question

How to use a property from gradle.properties inside android activity? Whenever I build the code it throws error. Is there a particular way that the properties can be accessed inside the activities?

Answer 1

You can't access the gradle.properties from your Activity.

The gradle.properties is used while you are building the app, it doesn't exist in runtime or inside your apk.

However you can set some values inside the BuildConfig class from your build.gradle script (reading from the gradle.properties for example).

Just use somenthing like:

buildConfigField "boolean", "MY_FLAG", "true"
buildConfigField "String" , "MY_KEY" ,  "\"XXXXX-XXXXX-XXX\""

Answer 2

in gradle.properties:

SIMPLE_STRING=ABC

in build.gradle:

android {
    buildTypes {
        debug {
            buildConfigField 'boolean', 'PREPROD', 'true'
            buildConfigField "String" , "MY_KEY" ,  SIMPLE_STRING
        }
     }
}
