以MirRgbdApp项目为例，可以看到vative_realsense.cpp中有映射java层（RGBDSensor.kt）调用的方法
JNINativeMethod logMethods[] = { {"updateRealSenseFw" , "(Ljava/lang/String;[B)Z", reinterpret_cast(updateFw)}, {"getRealSenseRGBDSerial", "()[Ljava/lang/String;",reinterpret_cast(getSerial)}, {"setRealSenseRGBD","(ILjava/lang/String;I)Z",reinterpret_cast(setRGBD)}, {"updateRealSenseRGBD","(ILjava/lang/String;)Z",reinterpret_cast(updateRGBD)}, {"startRealSenseRGBD","()Z",reinterpret_cast(startRGBD)}, {"openRealSenseRGBD","()Z", reinterpret_cast(openRGBD)}, {"closeRealSenseRGBD", "()V", reinterpret_cast(closeRGBD)}, {"getRealSenseLastError", "()Ljava/lang/String;", reinterpret_cast(getLastError)}, {"checkUpdateFw", "(Ljava/lang/String;)Z", reinterpret_cast(checkUpdateFw)}, {"setParkingMode", "(Z)V", reinterpret_cast(setParkingMode)} };
这里其实有很多参数是看不懂的，你看比如【(Ljava/lang/String;)Z】，这就需要对照表
参考参数对应java层的
