[hdev72]

hello dear friend im getting error when using java example in joinOrCreate: java.lang.reflect.InvocationTargetException

[doorbash]

Hi @hdev72 Are you getting this error while using the newest version of colyseus-kotlin (0.14.5) ? Java example is outdated

[hdev72]

Yes im using kotlin repo Error InvocationTargetException happening when state class has invalid SchemaField And now this error solved but now im getting new error in parmessage of incaming server message: Room > parseMessage

[hdev72]

joinOrCreate onError returns java.lang.Exception

private fun parseMessage(bytes: ByteArray) { . . . in below code im getting this error java.lang.NullPointerException:

Protocol.JOIN_ROOM -> { var offset = 1 val serializerId = String(bytes, offset + 1, bytes[offset].toInt() and 0xFF) offset += serializerId.length + 1 if (serializerId == "fossil-delta") { throw Error("fossil-delta is not supported") } if (bytes.size > offset) { serializer.handshake(bytes, offset) } onJoin?.invoke() connection?._send(Protocol.JOIN_ROOM) }

. . .

}

@hdev72 I've updated dependencies in latest commits. I wasn't able to reproduce. The example works fine for me.

i think if you update your https://github.com/doorbash/colyseus-android-chat repository will see this error

//implementation 'ir.doorbash:colyseus-java:2.3.3'
implementation "io.github.doorbash:colyseus-kotlin:0.14.5"

[hdev72]

i just updated implementation 'ir.doorbash:colyseus-java:2.3.3' to implementation "io.github.doorbash:colyseus-kotlin:0.14.5" in your android chat example and getting above error

you can download and test dear friend: https://apphteam.com/colyseus-android-chat-master_test_new_version.rar

i should use new version (kotlin:0.14.5) because old version (ir.doorbash:colyseus-java:2.3.3) have a bug: when server sending consecutive messages, previusCode in messageParser some times has another value for example receiving message is state change protocol but previusCode is not equals with receiving new protocol code number

Thanks for your help to solve this issue👍
