nit: I would just briefly add something along the lines of "This function must
be called early on in an application that wishes to use this library". I'm
approaching this with the notion that device_bluetooth is a stand-alone library
here.

Done.

+DEVICE_BLUETOOTH_EXPORT bool RegisterBluetoothJni(JNIEnv* env);

+#endif  // DEVICE_BLUETOOTH_ANDROID_BLUETOOTH_JNI_REGISTRAR_H_
