Android Studio - ＆gt; AVD管理器 - ＆gt;相机错误无法使用网络摄像头连接到相机

Question

我正在尝试将网络摄像头用于Android模拟器，但无论我做什么，都会出现#include <iostream> #include <cstring> #include <string> using namespace std; class Pizza { private: char name[15]; int price; char *ingredients; int reduction; public: Pizza (char *name= "", int price= 0, char *ingredients= "", int reduction= 0) { this->ingredients= new char [strlen(ingredients)+1]; strcpy(this->ingredients, ingredients); strcpy(this->name, name); this->price= price; this->reduction= reduction; } ~Pizza () { delete [] ingredients; } bool areSame(Pizza p) { for (int i = 0; i < strlen(this->ingredients) + 1; i++) if (this->ingredients[i] != p.ingredients[i]) return true; return false; } int getReduction() { return reduction; } void print() { cout << "name: " << name<< " ingredients: " << ingredients<< " Price: " << price; } }; class Pizzeria{ private: char name[15]; Pizza *p; int number_of_pizzas; public: Pizzeria(char *name= "") { strcpy(this->name, name); p = new Pizza [0]; number_of_pizzas = 1; } Pizzeria(const Pizzeria &x) { this->p = new Pizza [x.number_of_pizzas-1]; for (int i = 0; i < number_of_pizzas; i++) { this->p[i] = x.p[i]; } this->number_of_pizzas= x.number_of_pizzas; strcpy(this->name, x.name); } ~Pizzeria() { delete [] p; } void addPizza(Pizza P) {cout<<"fsfas"; for (int i = 0; i < number_of_pizzas; i++) { if (!(p[i].areSame(P))) { number_of_pizzas++; p[number_of_pizzas] = P; return; } } } void pizzasOnPromotion() { for (int i = 0; i < number_of_pizzas; i++) if (p->getReduction() > 0) p->print(); } void setName(char *name) { strcpy(this->name, name); } char getName() { return *name; } }; int main () { int n; char name[15]; Pizzeria p1(name); cin >> name; cin >> n; int reduc; for(int i = 0; i < n; i++){ char imp[100]; cin.get(); cin.getline(imp,100); int price; cin >> price; char ingredients[100]; cin.get(); cin.getline(ingredients,100); cin >> reduc; cout << "pls work"; Pizza p(imp,price,ingredients,reduc); p1.addPizza(p); } Pizzeria p2 = p1; cin >> name; p2.setName(name); char imp[100]; cin.get(); cin.getline(imp,100); int price; cin >> price; char ingredients[100]; cin.get(); cin.getline(ingredients,100); cin >> reduc; Pizza p(imp,price,ingredients,reduc); p2.addPizza(p); cout<<p1.getName()<<endl; cout<<"Pizzas on promotion:"<<endl; p1.pizzasOnPromotion(); cout<<p2.getName()<<endl; cout<<"Pizzas on promotion:"<<endl; p2.pizzasOnPromotion(); return 0; } 错误。

使用的程序：

Can't connect to the camera

Microsoft Windows 10 Pro, Version 10.0.16299 Build 16299

我尝试以管理员身份启动Android Studio 3.0.1，但错误仍然存​​在。但是，当我查看使用相机的权限时，我看不到Android Studio或Android Studio。我该如何解决这个问题？

Answer 1

我也有这个问题。我设法通过更新Android模拟器解决了这个问题。 sdk管理器中有可用的更新。 安装更新后，我的网络摄像头开始在模拟器上正常工作。

Answer 2

这是因为您已将前置摄像头和后置摄像头都设置为相同的硬件设备，即webcam0。尝试改回仿真状态，它将得到修复。

Answer 3

从 Webcam0>模拟

更改摄像头设置（前后）
