delete synthesizer这是个语法错误吗？

[Gaomaxxr]

    
    JNIEXPORT void JNICALL

    Java_com_cxp_learningvideo_FFEncodeActivity_releaseEncoder(JNIEnv *env, jobject thiz, jint synthesizer) {

        Synthesizer *s =  (Synthesizer *)synthesizer;

        delete synthesizer;
     }

源native-lib.cpp中这里delete synthesizer这一行报错：

...\LearningVideo-master\app\src\main\cpp\native-lib.cpp:137:9: error: cannot delete expression of type 'jint' (aka 'int')

这里我运行是有问题的，我c/c++不是很懂，ndk小白，能请教一下吗，谢谢

这明显是变量名写错了，上面定义的Synthesizer *s，下面应该是delete s;
