Android Question read WhatsApp messages

[catyinwong]

I would like to write an app that can help me organize and classify my messages. For now I only find examples about sending messages but I can't find anything about read or encrypting the messages. Anyone knows the way?

I can't find anything about read

you havn´t searched correctly or not...

Check Notification Listener

encrypting the messages

The messages send by Whatsapp are encrypted by whatsapp before sending/decrypted when receiving.

 

[catyinwong]

notification listener is not helpful because it doesn't read the whole conversation (i.e. excluding those which are sent out and those which are received when the WhatsApp is on)

and for the encryption part I refer to decrypting the local backup of messages.

Whatsapp does not provide a Api.
You can only use what is available. Here the notificationlistener.

I never saw any code which accesses the local datastore-Database and decrypt anything.
