props.put("serializer.class", "kafka.serializer.stringencoder");

producerconfig config = new producerconfig(props);

producer producer = new producer(config);

producerdata data = new producerdata("test-topic", "test-message");

producer.send(data);

i trying execute code got exception in thread "main" java.lang.nosuchmethoderror: scala.tuple2._1$mci$sp()i exception. added scala related jar file.plese suggedt me ??????

i faced same issue. check classpath see if sbt-launch.jar preceding scala-library.jar. both of them have same class; scala.tuple2 scala-library correct one.

after placing scala-library.jar higher in classpath solved issue.

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
