Installation

yarn add @starley/camera-preview-capacitor

or

npm install @starley/camera-preview-capacitor

Then run

npx cap sync

Extra Android installation steps

Important camera-preview 3+ requires Gradle 7. If you are using Gradle 4, please use version 2 of this plugin.

Open android/app/src/main/AndroidManifest.xml and above the closing </manifest> tag add this line to request the CAMERA permission:

<uses-permission android:name="android.permission.CAMERA" />

For more help consult the Capacitor docs.

Variables

This plugin will use the following project variables (defined in your app's variables.gradle file):

  • androidxExifInterfaceVersion: version of androidx.exifinterface:exifinterface (default: 1.3.6)

Extra iOS installation steps

You will need to add two permissions to Info.plist. Follow the Capacitor docs and add permissions with the raw keys NSCameraUsageDescription and NSMicrophoneUsageDescription. NSMicrophoneUsageDescription is only required, if audio will be used. Otherwise set the disableAudio option to true, which also disables the microphone permission request.

Extra Web installation steps

Add import '@starley/camera-preview-capacitor' to you entry script in ionic on app.module.ts, so capacitor can register the web platform from the plugin

then in html add

Add import { CameraPreview } from '@capacitor-community/camera-preview'; in the file where you want to use the plugin.

then in html add <div id="cameraPreview"></div>

and CameraPreview.start({ parent: "cameraPreview"}); will work.

Remember to add the style below on your app's HTML or body element:

ion-content {
  --background: transparent;
}

  --background: transparent;
}

If the camera preview is not displaying after applying the above styles, apply transparent background color to the root div element of the parent component Ex: VueJS >> App.vue component

<template>
  <ion-app id="app">
    <ion-router-outlet />
