        cordova --version

        node --version

        npm --version

Add string resources into strings.xml file :


    <string name="fb_app_id">232342323</string>
    <string name="fb_app_name">TESTAPP</string>

where 232342323 is facebook app id and TESTAPP is appname on faceboook


add yourapp_id in “ionic.config.json”

update varable config.xml

    <variable name="fb_app_id" value="18914XXXXXX683" />
    <variable name="fb_app_name" value="JXXi" />
