Android using Gradle Build flavors in the code like an if case

BuildConfig.FLAVOR gives you combined product flavor.So if you have only one flavor dimension:

productFlavors {    normal {    }    admin {    }}

Then you can just check it:

if (BuildConfig.FLAVOR.equals("admin")) {    ...}

But if you have multiple flavor dimensions:

flavorDimensions "access", "color"productFlavors {    normal {        dimension "access"    }    admin {        dimension "access"    }    red {        dimension "color"    }    blue {        dimension "color"    }}

there are also BuildConfig.FLAVOR_access and BuildConfig.FLAVOR_color fields so you should check it like this:

if (BuildConfig.FLAVOR_access.equals("admin")) {    ...}

And BuildConfig.FLAVOR contains full flavor name. For example, adminBlue.

To avoid plain string in the condition, you can define a boolean property:

productFlavors {    normal {        flavorDimension "access"        buildConfigField 'boolean', 'IS_ADMIN', 'false'    }    admin {        flavorDimension "access"        buildConfigField 'boolean', 'IS_ADMIN', 'true'    }}

Then you can use it like this:

if (BuildConfig.IS_ADMIN) {    ...}

You can define either different build configuration fields or different resource values (like string values) per flavor, e.g. (as per Google's gradle tips and recipes), e.g.,

android {  ...  buildTypes {    release {      // These values are defined only for the release build, which      // is typically used for full builds and continuous builds.      buildConfigField("String", "BUILD_TIME", "\"${minutesSinceEpoch}\"")      resValue("string", "build_time", "${minutesSinceEpoch}")      ...    }    debug {      // Use static values for incremental builds to ensure that      // resource files and BuildConfig aren't rebuilt with each run.      // If they were dynamic, they would prevent certain benefits of      // Instant Run as well as Gradle UP-TO-DATE checks.      buildConfigField("String", "BUILD_TIME", "\"0\"")      resValue("string", "build_time", "0")    }  }}

So in this case, something like

productFlavors {    normal {        dimension "access"        buildConfigField("boolean", "IS_ADMIN", "false")    }    admin {        dimension "access"        buildConfigField("boolean", "IS_ADMIN", "true")    }}

and then use it like

if (BuildConfig.IS_ADMIN) {    ...} else {    ...}

or if it is just to have different string values for different flavors, it can be done with different resValues and then you don't even need the if/then
