我的onAutoFocus方法是：
@Override
public void onAutoFocus(boolean success, Camera camera) {
// TODO Auto-generated method stub

    Log.d("onAutoFocus", "onAutoFocus="+success);
    setImg();

    if (success) {
        myCamera.takePicture(shutter, raw, jpeg);
    } else {
        System.out.println("failer");
    }
    isClicked = false;

}

没看到关键的报错地方， 不过可以看下 你的myCamera 对象实例化了吗 ？ 判断下 是否为null
