[Android AstraSDK 2.0.8 Beta2] GetBodies() JNI error

Hello everyone,

Device: Android 6.0.

The APP identifies the body and prints it 2-3 times. But sometimes the method m_body_frame.getBodies() raises this error:

com.omitech.view_orbbec_test E/art: JNI ERROR (app bug): expected jbyte but got value of 171 as argument 1 to void com.orbbec.astra.Body.<init>(byte, int, int, com.orbbec.astra.Vector3D, com.orbbec.astra.Joint[], com.orbbec.astra.HandPoseInfo)
com.omitech.view_orbbec_test A/art: art/runtime/java_vm_ext.cc:410] JNI DETECTED ERROR IN APPLICATION: bad arguments passed to void com.orbbec.astra.Body.<init>(byte, int, int, com.orbbec.astra.Vector3D, com.orbbec.astra.Joint[], com.orbbec.astra.HandPoseInfo) (see above for details)
com.omitech.view_orbbec_test A/art: art/runtime/java_vm_ext.cc:410]     from int com.orbbec.astra.NativeMethods.astra_bodyframe_body_list(long, java.util.ArrayList)

Do you know what may be the causes of this error?
