@intuiface/capacitor-plugin-screenshot v2.0.0
capacitor-plugin-screenshot
Capacitor plugin to take screenshot for iOS and Android devices.
The main goal of this plugin is to be able to take a screenshot of the application exactly as you see it. Even if there are playing videos, an iframe with some content, a cross-origin CSS...etc.
This plugin uses the takeSnapshot method of the WKWebView for iOS : https://developer.apple.com/documentation/webkit/wkwebview/2873260-takesnapshot.
And for Android, the MediaProjection API : https://developer.android.com/reference/android/media/projection/MediaProjection.
For the web, MediaDevices is use to cast the browser tab : https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getDisplayMedia.

To be able to take screenshot on Android, you have to declare a foreground service in the AndroidManifest.xml in the application tag :
<service android:enabled="true" android:foregroundServiceType="mediaProjection" android:name="com.intuiface.plugins.screenshot.ScreenCaptureService" />And also add permissions :
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE_MEDIA_PROJECTION" />The foreground service will ask you to cast your screen and this is mandatory to take screenshot with the MediaProjection API.
