根据android版本从两个版本的库中加载类

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.
