There are my config to support L and old versions of android:

apply plugin: 'com.android.application'

android {
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.example.uladzimir_klyshevich.myapplication"
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }


    productFlavors {
        l {
            minSdkVersion 'android-L'
            targetSdkVersion 'android-L'
            compileSdkVersion 'android-L'
        }
        old {
            minSdkVersion 10
            targetSdkVersion 20
            //TODO comment second line if build is not compiles for "L"
            compileSdkVersion 20
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    lCompile 'com.android.support:appcompat-v7:21.+'
    oldCompile 'com.android.support:appcompat-v7:19.1.0'
}

As result you will have flavors:

oldDebug
oldRelease
lDebug
lRelease

And can install your application on old versions of android.
