In the Clover device, you need to evaluate and test your Android app's SDK version to ensure device compatibility.

Minimum SDK

The minimum SDK version (minSdkVersion) is the earliest release of the Android SDK that your application can run on.

For your app to be installed on all Clover devices, set the app's minimum SDK to 17.
For specific Clover devices, set the minSdkVersion of your app based on the following table:

Clover device	SDK version for specific devices
Station	17; Use this version to allow your app to be installed on any Clover device.
Mini	19
Flex 1	22
Mini 2	27
Flex 3 Mini 3 Clover Station Duo 2 Clover Station Solo	29
Flex 4 Flex Pocket Clover Compact	33

Target SDK

Note: While we recommend a targetSdkVersion of 25 or lower, higher versions are supported if thoroughly tested.

Android uses the target SDK version targetSdkVersion to determine which compatibility layers to enable for your app to run correctly.

Troubleshoot issues with target SDK level

Clover supports apps with a target SDK level of 25 or earlier.

Starting with SDK level 27, Android introduced the account access and discoverability policy, which explicitly requests access to Clover merchant accounts and disrupts the expected merchant flow. To make sure your apps function correctly and are approved for publication on the Clover App Market, set the targetSdkVersion to 25 or lower.

Compile SDK

Set the compile SDK version compileSdkVersion to the highest API level available from Google, as listed in the SDK Platform release notes. Your IDE uses this version to compile your app when you publish a .apk file. Using the highest available level ensures that all software libraries in your project compile successfully.
