Crash when launch camera android permission

Question

I'm using imported Scalibrary module sample app for image processing filter. It has two main button open camera and open gallery.

It's working fine on android Kitkat but when I try to launch the camera on android 9 It crash

I have tried adding : android:requestLegacyExternalStorage="true" on manifest but no luck

Note : I have already given permission camera and external write read storage on manifest

Update : Apparently I have to make the permission pop up for it to works because Im currently enabling it manually in the settings how do I do that ?

What Im I missing ?

You have to request *Runtime Permission* and get approval from user in API 24 and up. Check more here: https://developer.android.com/distribute/best-practices/develop/runtime-permissions — Md. Asaduzzaman, Dec 30 '19 at 07:06
Open camera only after checking if permission is already granted or not. If not ask for the permission first. — Rohit5k2, Dec 30 '19 at 07:10

hi you can use these permission in your manifest file with other permission,

<uses-feature
android:name="android.hardware.camera.any"
android:required="true" />
<uses-feature
android:name="android.hardware.camera.autofocus"
android:required="false" />
