以MirRgbdApp項(xiàng)目為例，可以看到vative_realsense.cpp中有映射java層（RGBDSensor.kt）調(diào)用的方法

JNINativeMethod logMethods[] = { {"updateRealSenseFw" , "(Ljava/lang/String;[B)Z", reinterpret_cast<void*>(updateFw)}, {"getRealSenseRGBDSerial", "()[Ljava/lang/String;",reinterpret_cast<void*>(getSerial)}, {"setRealSenseRGBD","(ILjava/lang/String;I)Z",reinterpret_cast<void*>(setRGBD)}, {"updateRealSenseRGBD","(ILjava/lang/String;)Z",reinterpret_cast<void*>(updateRGBD)}, {"startRealSenseRGBD","()Z",reinterpret_cast<void*>(startRGBD)}, {"openRealSenseRGBD","()Z", reinterpret_cast<void*>(openRGBD)}, {"closeRealSenseRGBD", "()V", reinterpret_cast<void*>(closeRGBD)}, {"getRealSenseLastError", "()Ljava/lang/String;", reinterpret_cast<void*>(getLastError)}, {"checkUpdateFw", "(Ljava/lang/String;)Z", reinterpret_cast<void*>(checkUpdateFw)}, {"setParkingMode", "(Z)V", reinterpret_cast<void*>(setParkingMode)} };

這里其實(shí)有很多參數(shù)是看不懂的，你看比如【(Ljava/lang/String;)Z】，這就需要對(duì)照表

參考參數(shù)對(duì)應(yīng)java層的
