I get a parser error when trying to run on a device with Android 5.
Is this version not supported.
The device is a Seuic RFID reader and it is a brand new device. However the device cant be upgraded.

What project type/libraries version do you use?
Appery.io provides a typical .apk file, but we can't guarantee it's work on some specific, not standard devices, which don't have a standard Android version or hardware
