Here you can make the required changes:
Setting the correct compileSdkVersion, minSdkVersion, and targetSdkVersion is important. As you might imagine in a world with Gradle and Android Studio, these values are integrated into the tools system through inclusion in your module’s build.gradle file (also available through the Project Structure option in Android Studio)
You’ll notice a relationship between the three values:
minSdkVersion <= targetSdkVersion <= compileSdkVersion
Ideally, the relationship would look more like this in the steady state:
minSdkVersion (lowest possible) <= targetSdkVersion == compileSdkVersion (latest SDK)
You’ll hit the biggest audience with a low minSdkVersion and look and act the best by targeting and compiling with the latest SDK — a great way to Build Better Apps.
