Hi @juthawong
Can you please mention in which file you made the change. Also what did you change?

[juthawong]

Hello @abhishekSDEI , @govind38 .

Sorry , I just open my Github.

Just update conceal.gradle file to 1.1.2 or 1.1.3.

Here is the references : https://github.com/juthawong/cordova-safe/blob/master/src/android/conceal.gradle

I tested it on Cordova 6.4.0 and it works!.

Thanks.

P.s. I also submitting pull request for the awesome project owner for review because he is a creator and he knows best.

Hello @juthawong

Thanks for the quick reply.

Unfortunately it didn't fix my issue. I updated the conceal.gradle file to both 1.1.2 & 1.1.3 but neither fixed my issue. :(

In case it helps, I got mine working in ionic 3 after downgrading cordova

npm uninstall cordova
npm install -g [email protected]

Thanks for reply. But I had to release app without that feature. Anyway now I can use in future.

I already found this solution somewhere else but then it's didn't worked.
Ionic Info

Ionic:

ionic (Ionic CLI) : 4.0.5 (C:\Users\bdomi\AppData\Roaming\npm\node_modules\ionic)
Ionic Framework : ionic-angular 3.9.2
@ionic/app-scripts : 3.1.11

Cordova:

cordova (Cordova CLI) : 8.0.0
Cordova Platforms : not available

System:

Android SDK Tools : 26.1.1
NodeJS : v8.11.3 (C:\Program Files\nodejs\node.exe)
npm : 6.3.0
OS : Windows 10

So now what I did is the folowing.
In the platforms/android/cordova-safe/starter-conceal.gradle change this
compile('com.facebook.conceal:conceal:1.0.0@aar')
to this
compile('com.facebook.conceal:conceal:2.0.1@aar')
I hope it will work for you too.
