Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@capacitor/privacy-screen

zh-CN en

本项目基于 @capacitor/[email protected] 开发。

简介

隐私屏幕保护 API,可在应用进入后台时隐藏敏感内容,防止被查看。本插件是 capacitor 生态系统中的核心插件,为跨平台应用开发提供设备差异化适配能力,兼容 capacitor 的 Android、iOS 等主流移动平台及浏览器环境中使用,本文档仅说明在 OpenHarmony 系统中的使用情况。

支持平台

  • OpenHarmony:5.0+

下载安装

通过命令行或手动引入即可快速安装插件,支持从npm仓库获取。

命令行安装(推荐)

安装hionic CLI:

npm install -g hionic

以下两种方式中任选其一即可,无需重复操作:

npm安装:

# 安装插件
npm install @capacitor/privacy-screen

# 同步插件
hionic sync

hionic CLI安装:

hionic plugin add @capacitor/privacy-screen

手动引入安装

根据插件源码中 plugin.xml 配置在项目中引入插件:

1. 添加插件配置

根据 plugin.xmlconfig-json 项,找到 entry 模块中 capacitor.plugins.json 文件,并根据 param 标签添加配置如下:

{
  "pkg": "@capacitor/privacy-screen",
  "classpath": "PrivacyScreen"
}

2. 修改 CMake 配置

根据 plugin.xmlCMakeLists 项,找到 capacitor 模块,路径为 target 字段的 CMakeLists.txt 文件,并添加 add_subdirectorytarget_link_libraries 如下:

// ...
add_subdirectory(PrivacyScreen)
// ...

// ...
target_link_libraries(capacitor PUBLIC
  "-Wl,--whole-archive"
  // ...
  PrivacyScreen
  // ...
  "-Wl,--no-whole-archive"
);

3. 复制源码文件

根据 plugin.xmlsource-file 项,根据 src 字段找到需要复制的文件,并复制到对应的目录:

将插件源码中 src/main/cpp/PrivacyScreen 目录下的 PrivacyScreen.h、PrivacyScreen.cpp、CMakeLists.txt 文件引入到 capacitor 模块中 src/main/cpp/PrivacyScreen 目录下。

将源码中 src/main/ets/components/PrivacyScreen 目录下的 PrivacyScreen.ets、PrivacyScreenDialog.ets 文件引入到 capacitor 模块中 src/main/ets/components/PrivacyScreen 目录下。

capacitor 模块的 build-profile.json5 文件中,buildOption/arkOptions/runtimeOnly/sources 配置项数组中加入拷贝的 ets 文件路径:

"buildOption": {
  "arkOptions": {
    "runtimeOnly": {
      "sources": [
        "./src/main/ets/components/PrivacyScreen/PrivacyScreen.ets"
      ]
    }
  }
}

卸载

# 卸载 privacy-screen 插件
hionic plugin remove @capacitor/privacy-screen

约束与限制

兼容性

在以下版本中已测试通过:

  1. SDK: 5.0.5(17); IDE: DevEco Studio: 6.0.0; ROM: 5.1.0.150;

权限要求

OpenHarmony 需要申请隐私窗口权限,在主工程的 module.json5requestPermissions 添加 ohos.permission.PRIVACY_WINDOW 权限,示例如下:

{
  "name": "ohos.permission.PRIVACY_WINDOW",
  "reason": "$string:privacy_window",
  "usedScene": {
    "abilities": [
      "EntryAbility"
    ],
    "when": "always"
  }
}

更多权限说明参考:申请应用权限

使用示例

基础示例:开启关闭隐私屏幕

import { PrivacyScreen } from '@capacitor/privacy-screen';

// Enable privacy screen with default settings
await PrivacyScreen.enable();

// Enable with platform-specific configuration
await PrivacyScreen.enable({
  android: {
    dimBackground: true,
    privacyModeOnActivityHidden: 'splash'
  },
  ios: {
    blurEffect: 'dark'
  }
});

// Disable privacy screen
await PrivacyScreen.disable();

// Check if privacy screen is enabled
const { enabled } = await PrivacyScreen.isEnabled();

基础示例:暗屏保护

import { PrivacyScreen } from '@capacitor/privacy-screen';

// Enable privacy screen when navigating to a secure screen
async function navigateToSecureScreen() {
  await PrivacyScreen.enable({
    android: { dimBackground: true },
    ios: { blurEffect: 'dark' }
  });
  // Navigate to your secure screen
}

// Disable when navigating to a non-secure screen
async function navigateToPublicScreen() {
  await PrivacyScreen.disable();
  // Navigate to your public screen
}
