Error plugin Facebook

Hi !

i try build my app and i have this error:

 AAPT: error: resource string/fb_app_id (aka myapp:string/fb_app_id) not found.

AAPT: error: resource string/fb_app_name (aka myapp:string/fb_app_name) not found.

Any help please? I try the commands

  • ionic cordova platform rm android
  • ionic cordova platform add android
  • ionic cordova build android

But the results not were succesfully

cordova: 8.0.0
cordova-android: 7.0.0
android-target: android-26
plugin-facebook4: 1.9.1

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

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

Thanks for your response @vibinflogesoft .
I checked my appid and my appname and it’s right

Same thing here. Did you find the problem?

See documentation for cordova-android >= v7

The easiest solution is to

Add string resources into (I am using linux ubuntu this is my ionic project path) file : /home/user/js/fb4/platforms/android/app/src/main/res/values/strings.xml

<string name="fb_app_id">59523234234</string>
<string name="fb_app_name"></string>

and my project now works!

As mentioned here

@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
