Here's a simplified reproducer:\r\n\r\n```java\r\n@RunWith(AndroidJUnit4.class)\r\n@SmallTest\r\npublic class MsgpackTest {\r\n\t@Test\r\n\tpublic void testPutString() throws Exception {\r\n\t\tByteArrayOutputStream out = new ByteArrayOutputStream();\r\n\t\tMessagePacker packer = MessagePack.newDefaultPacker(out);\r\n\t\tpacker.packString(\"hello android\");\r\n\t}\r\n}\r\n```\r\n\r\nThe error message:\r\n\r\n```\r\njava.lang.NoSuchMethodError: No virtual method position(I)Ljava/nio/ByteBuffer; in class Ljava/nio/ByteBuffer; or its super classes (declaration of 'java.nio.ByteBuffer' appears in /system/framework/core-libart.jar)\r\n  at org.msgpack.core.buffer.MessageBufferU.resetBufferPosition(MessageBufferU.java:70)\r\n  at org.msgpack.core.buffer.MessageBufferU.putBytes(MessageBufferU.java:232)\r\n  at org.msgpack.core.MessagePacker.addPayload(MessagePacker.java:1073)\r\n  at org.msgpack.core.MessagePacker.addPayload(MessagePacker.java:1043)\r\n  at org.msgpack.core.MessagePacker.packStringWithGetBytes(MessagePacker.java:659)\r\n  at org.msgpack.core.MessagePacker.packString(MessagePacker.java:732)\r\n  ...\r\n```\r\n\r\nThis is most probably due to the changes in #514 (cc @ppkarwasz). The test succeeds when running with msgpack-core version 0.8.18.","author":{"url":"https://github.com/dbrgn","@type":"Person","name":"dbrgn"},"datePublished":"2019-11-21T15:00:09.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":10},"url":"https://github.com/516/msgpack-java/issues/516"}
