In Android development, minimum SDK and target SDK are two important parameters that define the compatibility of an app on different Android devices.
The minimum SDK (Software Development Kit) is the lowest version of Android that an app can run on. This means that the app will only be available to users with devices that have an operating system version equal to or higher than the specified minimum SDK. If a user tries to install the app on a device with an operating system lower than the minimum SDK, the installation will fail.
The target SDK is the version of Android that an app is specifically designed for, and it determines the highest version of Android that an app supports. This means that an app can run on any device with an operating system equal to or lower than the target SDK, but it may not be optimized to take advantage of features available on higher versions of Android.
It's important to consider both minimum SDK and target SDK when developing an Android app because they impact the number of potential users an app can reach based on the version of Android they are running. Additionally, it's important to update the app's target SDK regularly to ensure it is taking advantage of the latest Android features and optimizing performance for users running the latest versions of Android.
