look like the installation didn’t picked `ANDROID_SDK_VERSION` when you installed it, try to reinstall it with explicitly specifying it ``` ionic cordova plugin rm cordova-plugin-facebook4 --save ionic cordova plugin add cordova-plugin-facebook4 --variable ANDROID_SDK_VERSION="4.+” --variable --variable APP_ID="123456789" --variable APP_NAME="myApplication" --save ``` ---

Also the properties `ANDROID_SDK_VERSION` has just been renamed, that could explain it 😉 New name : `FACEBOOK_ANDROID_SDK_VERSION` ``` ionic cordova plugin rm cordova-plugin-facebook4 --save ionic cordova plugin add cordova-plugin-facebook4 --variable FACEBOOK_ANDROID_SDK_VERSION="4.+” --variable --variable APP_ID="123456789" --variable APP_NAME="myApplication" --save ``` ---

`cordova-plugin-facebook4@3.0.0` came out 12 hours ago. Might be worth a try to go for 2.5.0. ---

There is almost no change in 3.0.0, the difference is that as from now on the Facebook SDK for iOS and Android are going to always be sync Also I would rather try with 3.0.0 that 2.5.0 because in 3.0.0 the Facebook Android SDK is set to 4.36.0 and not 4.+ ---

@zwacky @reedrichards Thanks for your help. I just upgrade to v 3.0.0 and get the same error that pointed in the last comment with FACEBOOK\_ANDROID\_SDK\_VERSION, It’s like the plugin isn’t reading the value (4.+) from config.xml, so as a **workaround** I have harcoded that value in the file: my-app/platforms/android/project.properties as the following: cordova.system.library.1=com.facebook.android:facebook-android-sdk:4.+ Then I ran the android build and it works! ---

I thought about it and I think it didn’t pick the value because you are using a cordova cli which is probably older than v7 it’s documented see “older cordova cli” with a link to an issue with different solutions: [https://github.com/jeduan/cordova-plugin-facebook4/blob/master/docs/android/README.md](https://github.com/jeduan/cordova-plugin-facebook4/blob/master/docs/android/README.md) but a solution is of course to upgrade the cordova cli anyhow if you solved it, you solved it, cool ---

You just saved my day sir ! But yeah why is it such a mess i’ve read like all the internet and you were he only one talking about project.properties to fix this issue … It’s really like the plugin is not reading the value from config.xml … ---
