Load classes from two versions of library depending on android version

Question

I'm trying to use two modified Apache POI libraries. Each libray has modifications to work properly on android 4.+ and 5.+.

I need to import specific class of specific library depending on android version.

For example:

Android 4.+ versions:

import org.apache.poi.xssf.usermodel.XSSFWorkbook; of compile files('libs/aa-poi-3.10-min-0.1.5.jar')

Android 5.+ versions:

import org.apache.poi.xssf.usermodel.XSSFWorkbook; of compile files('libs/poi-3.12-android-a.jar')

How could i do this? Thanks

Answer 1

Define two flavours

productFlavors {
    android4plus {
        minSdkVersion 14
    }
    android5plus {
        minSdkVersion 21
    }
}

Now you can setup different dependencies per flavour

android4plusCompile files('libs/aa-poi-3.10-min-0.1.5.jar')
android5plusCompile files('libs/poi-3.12-android-a.jar')

As result, you can switch between flavours during development and will have two APK files to distribute.
