Go to SETTINGS->Location and Security-> Device Administrator and deselect the admin which you want to uninstall.
Now uninstall the application. If it still says you need to deactivate the application before uninstalling, you may need to Force Stop the application before uninstalling.
Solution 2 - Android
You could also create a new DevicePolicyManager and then use removeAdmin(adminReceiver) from an onClickListener of a button in your app
//set the onClickListener here
{
ComponentName devAdminReceiver = new ComponentName(context, deviceAdminReceiver.class);
DevicePolicyManager dpm = (DevicePolicyManager)context.getSystemService(Context.DEVICE_POLICY_SERVICE);
dpm.removeActiveAdmin(devAdminReceiver);
}
And then you can uninstall

On Samsung go to "Settings" -> "Lock screen and security" -> "Other security settings" -> "Phone administrators" and deselect the admin which you want to uninstall.
The "security" word was hidden on my display, so it was not obvious that I should click on "Lock screen".
