Hi@homeres  
This issue is related with your facebook appid and appname  
Try to add the right appid and appname while installing the plugin

```auto
ionic cordova plugin add cordova-plugin-facebook4 --variable APP_ID="Your APPID" --variable APP_NAME="Your APPNAME"

```

<string name="fb_app_name">hajmo.ba</string>

```

and my project now works!

@sunojvijayan if you go that way, don’t forget that next time you will remove/add your platform you will have to enter these keys again
