Android EGL eglCreateWindowSurface 调用问题

eglCreateWindowSurface 函数的第三个参数怎么填呢？查了好几天，都没怎么说这个参数的问题。

Android系统：4.1.1,硬件：小米2（MIUI版本：2.12.21)

以下是我的测试代码(jni代码)：

EGLDisplay myDisplay = NULL;
EGLint majorVer = 0, minorVer = 0;
EGLBoolean ret = EGL_TRUE;
EGLConfig eglConfig;
EGLint num_config;
EGLSurface windowSurface;
NativeWindowType win = NULL; //就是这个变量，不知道怎么写～～
EGLContext myContext;

int ViewCreate(){

myDisplay = eglGetDisplay(EGL_DEFAULT_DISPLAY);

if(EGL_NO_DISPLAY == myDisplay)
LOGI("eglGetDisplay no display");

ret = eglInitialize(myDisplay, &majorVer, &minorVer);

LOGI("ret: %d major: %d minor: %d", ret, majorVer, minorVer);

EGLint attribs[] = {
EGL_RED_SIZE, 4,
EGL_GREEN_SIZE, 4,
EGL_BLUE_SIZE, 4,
EGL_RENDERABLE_TYPE, EGL_OPENGL_ES2_BIT,
EGL_NONE
};

ret = eglChooseConfig(myDisplay, attribs, &eglConfig, 1, &num_config);

LOGI("ret: %d num: %d", ret, num_config);

EGLint surfAttribs[] = {
EGL_COLORSPACE, EGL_COLORSPACE_sRGB,
EGL_NONE
};

windowSurface = eglCreateWindowSurface(myDisplay, eglConfig, win, surfAttribs);

if(EGL_NO_SURFACE == windowSurface){
LOGI("create surface error");
return 0;
}

myContext = eglCreateContext(myDisplay, eglConfig, NULL, NULL);

if(EGL_NO_CONTEXT == myContext){
LOGI("EGL_NO_CONTEXT");
return 0;
}

eglMakeCurrent(myDisplay, windowSurface, windowSurface, myContext);

eglBindAPI(EGL_OPENGL_ES_API);
}

，返回的版本号是：1.4，
但在eglCreateWindowSurface的时候程序直接崩溃，
Fatal signal 11 (SIGSEGV) at 0x00000058 (code=1), thread 8356，看有好多人遇到这个问题，但不知道大家解决怎么样了？

java代码：
package com.android.Test;
public class TestView {
public TestView (){
TestLib.ViewCreate();
}
protected void finalize(){
TestLib.ViewDelete();
}
}

package com.android.Test;

public class TestLib {

static {
System.loadLibrary("Test");
}
public static native void ViewCreate();
}
