如何在本机应用程序中禁用屏幕截图? [英] How to disabled screenshoots in react-native app?

问题描述

我已经使用react-native制作了一个移动应用程序(目前仅适用于android，它不是expo应用程序)，并且我想禁止用户在该应用程序打开时进行屏幕截图.我知道不可能完全禁用此功能，但我想至少要更难截取屏幕截图.我找到了一些示例，但是我不知道如何实现它们，例如:

I have made a mobile app using react-native (only android for now and it is not an expo app) and I would like to forbid users to take screenshots while the app is open. I know it is impossible to disable this completely but I would like to make it at least more difficult to take screenshots. There are some examples I found but I don't how to implement them for example:

如何防止Android屏幕捕获

我试图放:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_SECURE,
                           WindowManager.LayoutParams.FLAG_SECURE);

在我的app_name/android/app/src/main/java/com/app_name/MainApplication.java文件中的

在onCreate()方法中，然后我无法编译该应用程序以查看其是否有效.同样，当我尝试创建这样的类时:

in my app_name/android/app/src/main/java/com/app_name/MainApplication.java file, in the onCreate() method and then I can't compile the app to see if it works. The same is when I tried to create a class like in this:

当我的应用程序进入后台时，如何防止Android截屏?

此问题有一些npm-s，但我在安装/使用它们方面也没有成功.

There are some npm-s for this issue but I had also no success in installing/using them.

有人知道如何设置标志，以便我的react-native(android)应用程序的用户在使用该应用程序时无法截屏吗?

Does anyone know how to set a flag so the users of my react-native (android) app can't take screenshots while using the app?

添加时出现错误:getWindow().setFlags，然后在android-studio中按Build:

The error I get when add: getWindow().setFlags and then press Build in android-studio is:

错误:软件包WindowManager不存在

error: package WindowManager does not exist

，我也尝试过此软件包:

and I also tried to this package:

yarn add react-native-anti-screenshot
yarn add v1.7.0
[1/4] Resolving packages...
error An unexpected error occurred: "https://registry.yarnpkg.com/react-native-anti-screenshot: Not found".
info If you think this is a bug, please open a bug report with the information provided in "/home/mislav/workspace2/umye/yarn-error.log".
info Visit https://yarnpkg.com/en/docs/cli/add for documentation about this command.

好像没有简单的方法可以禁用屏幕截图，或者我错过了什么吗?

Looks like there is no easy solution to disable screenshots or did i miss something?

我在开发移动应用程序方面还很陌生，所以请您帮我尽可能简单地解释一下.

I'm pretty new in developing mobile apps so please if you can help me explain it as simple as you can.

谢谢！

推荐答案

在MainActivity.java文件中尝试以下代码:

try this code in MainActivity.java file:

  @Override
  protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
    if(android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) 
    {
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_SECURE, 
        WindowManager.LayoutParams.FLAG_SECURE);
    };

 }
