It Looks like this problem appear after I start QBluetoothServiceDiscoveryAgent->start and before The program enter to QBluetoothServiceDiscoveryAgent->serviceDiscovered.

It means that this method (java.lang.String java.lang.String.toString()) is call in QBluetoothServiceDiscoveryAgent.

I updated SDK and nothing has changed.

Should i write this in java, becouse with QBluetoothServiceDiscoveryAgent is something wrong?
