Set variables in build.gradle

In my build.gradle (Module: app) I specified one buildConfigField and one resValue variable.

buildTypes {
    release {
        debuggable false
        minifyEnabled true
        shrinkResources true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

        buildConfigField "String", "APP_EXP_DATE", "\"DEC 31 23:59:59 EDT 2018\""
        resValue         "String", "app_exp_date", "\"DEC 31 23:59:59 EDT 2018\""
    }
}

Then I expected them to use in my Java code like this:

BuildConfig.APP_EXP_DATE
R.string.app_exp_date

but unfortunately I am experiencing the following errors:

error: cannot find symbol variable APP_EXP_DATE

error: illegal start of type

How can I make it work to be able to access variables from gradle in my Java code?

Well, you have some options:

  1. Define your strings and values under defaultConfig as follow:

    android {
    // your code
    defaultConfig {
        // your code
        resValue "string", "<key>", "<value>" 
        buildConfigField "string", "<key>", "<value>"
        // ...
    }
    // your code
}

  2. You can put your string in both Release and Debug type

    buildTypes {
    release {
        // your code
        resValue "string", "<key>", "<value>" 
        buildConfigField "string", "<key>", "<value>"
        // ...
    }
    debug {
        // your code 
        resValue "string", "<key>", "<value>" 
        buildConfigField "string", "<key>", "<value>"
        // ...
    }
}

Hope this help!

How can I make it work to be able to access variables from gradle in my Java code?

The issue in your codes seems to be using in release buildType which might cause the issue (not resolving it.

But, this is how it should be :

In gradle.properties:

ExpDate="DEC 31 23:59:59 EDT 2018"

In app/Build.gradle (Note that it should be in android block code):

def APP_EXP_DATE = '"' + ExpDate + '"' ?: '"Define Expire Date"'
android.buildTypes.each { type -> 
    type.buildConfigField 'String', 'APP_EXP_DATE', ExpDate

}

Usage:

BuildConfig.APP_EXP_DATE

As a Toast: 

Toast.makeText(activity, BuildConfig.APP_EXP_DATE, Toast.LENGTH_LONG).show()
