Short explanation on Gradle, minSdkVersion, maxSdkVersion, compileSdkVersion and targetSdkVersion in Android

Image
Gradle:The Android build system compiles app resources and source code, and packages them into APKs that you can test, deploy, sign, and distribute. Android Studio uses Gradle.
The Android plugin for Gradle works with the build toolkit to provide processes and configurable settings that are specific to building and testing Android applications.Gradle and the Android plugin run independent of Android Studio. Gradle architecture is shown below.




Example: android { compileSdkVersion 27 buildToolsVersion “26.0.2” defaultConfig { applicationId “com.example.checkyourtargetsdk" minSdkVersion 15 targetSdkVersion 27 versionCode 1 versionName “1.0” } }
minSdkVersion:minSdkVersion is the lower bound for your app. The minSdkVersion is one of the signals the Google Play Store uses to determine which of a user’s devices an app can be installed on.
 your app’s minSdkVersion must be at least as high as your dependencies’ minSdkVersion
When deciding on a minSdkVersion, you s…
