Java – File not found when trying to compile Telegram source code

I’m trying to build an app like Telegram. I downloaded their source code ( https://github.com/DrKLO/Telegram) (for Android).

My main problem is that when I try to compile the code and export it to my phone, I get this error using Android Studio :

Error: There is a problem with the configuration of the discovery task “:TMessagesProj:packageDebug”.

File ‘C:\Users\Bogdan\Desktop\Telegram\Telegram-master\TMessagesProj\config\debug.keystore’ specified for property ‘signingConfig.storeFile’ does not exist.

It is clear that there is one file missing, but which one, how to solve this problem?

Thanks!

P.S. Could you please provide a link to the source code of an application similar to this application or similar to WhatsApp?

Change Telegram/TMessagesProj/build.gradle and remove or comment out the signing options in the gradle configuration as follows:

apply plugin: 'com.android.application'

    mavenCentral()

}
