Extra Android installation steps
Important camera-preview
3+ requires Gradle 7.
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.
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 '@capgo/camera-preview'
to you entry script in ionic on app.module.ts
, so capacitor can register the web platform from the plugin
