ext variables with flavor doesn't work with multiple dimension

Question

I have the same structure as the code below and I want to put prefix to the applicationId and suffix without dots and use the applicationId value at the end within the gradle file.

I don't want to use applicationIdSuffix because it add dots automatically and I can't get it's value on gradle neither the complete applicationId.

flavorDimensions "type", "version"

productFlavors.all {
       ext.appIdPrefix = "com.example"
       ext.appId = ""
       ext.appIdSuffix = ""
    }

productFlavors {

        flavor1 {
            dimension "type"
            appId = ".flavor1"
        }

       full {
            dimension "version"
            appIdSuffix = "Full"
        }
}

productFlavors.all  {
     applicationId appIdPrefix + appId + appIdSuffix
}

Now when I run my app with "flavor1full" the applicationId is "com.exmaple.flavor1" only and doesn't get the value of appIdSuffix

How I can solve that ?

Instead of changing app ID for each flavor, try to iterate over applicationVariants:

applicationVariants.all { variant ->
    def flavors = variant.productFlavors
    variant.mergedFlavor.applicationId = flavors[0].appId + flavors[1].appIdSuffix ;
}

This will iterate through every combination of flavors twice because of the two build types. See also Multi-Dimension Flavor ApplicationId

Also note a typo in your question: appIdSuffix "Full" should be appIdSuffix="Full"

Assuming your ultimate goal is to build different app flavors with different app IDs, you should be able to use something like this:

flavorDimensions "type"

productFlavors.all {
    ext.appIdPrefix = "prefix"
    ext.appId = "hello.world"
}

productFlavors {
    partial {
        dimension "type"
        ext.appIdSuffix = "suffix1"
    }

    full {
        dimension "type"
        ext.appIdSuffix = "suffix2"
    }
}

productFlavors.all {
    applicationId appIdPrefix + "." + appId + "." + appIdSuffix
}

The above will produce you application IDs ending with suffix1 or suffix2 depending on build variant chosen. Not sure I understand why you need another dimension for that.

Yes, but the problem with multiple dimension. if full assigned to another dimension and doing changes to third variable in ext. it will not appear in the applicationId — Moaz Rashad, Feb 20 '19 at 13:36
