Hi.

 

Until somebody more competent replies,  can you check if you have permissions for using camera?

 

Depending on your use case you may want these:

 

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

 

Regards,

Petar
