can 1 please?

inside manifest file:

<uses-feature android:name="android.hardware.camera" /> <uses-feature android:name="android.hardware.camera.autofocus" /> <uses-permission android:name="android.permission.camera"></uses-permission>

do not forget request permissions here discribed:

https://developer.android.com/training/permissions/requesting.html

in breif:

    if (contextcompat.checkselfpermission(this, manifest.permission.camera) != packagemanager.permission_granted) {         activitycompat.requestpermissions(this, new string[]{manifest.permission.camera}, 50); }    else {             startcamera();
