You can use

public boolean isPermissionAllowed(String permissionSetName, String packageName, String employeeId, AccountRole minimumRole)

in Roles.java in clover-android-sdk

I don't see a list of permission set names and packages, but you should be able to get the names from a sandbox app by querying the on device database using RolesContract.java.

For example:

Uri uri = RolesContract.PermissionSets.contentUriWithAccount(CloverAccount.getAccount(MainActivity.this));
ContentProviderClient client = getContentResolver().acquireUnstableContentProviderClient(uri);
if (client != null) {
  Cursor cursor = null;

  try {
    cursor = client.query(RolesContract.PermissionSets.contentUriWithAccount(CloverAccount.getAccount(MainActivity.this)), null, null, null, null);
    if (cursor != null) {
      for (cursor.moveToFirst(); !cursor.isAfterLast(); cursor.moveToNext()) {
        String name = cursor.getString(cursor.getColumnIndex(RolesContract.PermissionSets.NAME));
        String label = cursor.getString(cursor.getColumnIndex(RolesContract.PermissionSets.LABEL));
        Log.i("FetchPermissionSets", String.format("name: %s, label: %s", name, label));
      }
    }
  } catch (Exception e) {
    e.printStackTrace();
  } finally {
    if (cursor != null) {
      cursor.close();
    }
  }
}

Then you can manually get the package names by looking at the Permissions tab in com.clover.employees. The package name is the package name corresponding to the group that the permission is under.

For example, Perform manual refund for manual transaction falls under:
I/PermissionSets( 5547): name: PERFORM_MANUAL_REFUND, label: Perform manual refund
package:com.clover.manualtransaction

If you want to test isPermissionAllowed(...) before digging up your specific permission set, can try ADD_CUSTOM_DISCOUNT for com.clover.register (corresponds to Apply custom discounts in register)

You can use EmployeeConnector#getEmployee() to get the active employee.
A sample call is:

Roles.isPermissionAllowed("ADD_CUSTOM_DISCOUNT", "com.clover.register", activeEmployee.getId(), null)
