Android SDK version

The Build class allows you to get current version of Android.

// kotlin
import android.os.Build
...
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){
    // ... do something for lollipop and above 
} else{
    // ... do something when an SDK is before lollipop
}

You can specify minimum SDK version and target SDK version in the module-level build.gradle file. 

android {
    compileSdkVersion 29

    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 29
        // ... other options
     }
}

java support

Different versions of android does not support all features of Java 7/8. For example, try-with-resource feature need minSdkVersion is set to 19 or higher. Same thing with lambdas and stream API.

But android plugin for Gradle v4.0+ allows to use most features without changing minSdkVersion. Read more how add android gradle plugin on old projects.

You can specify java version in the module-level build.gradle file.

android {
    // ...
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = '1.8'
    }
}
