I had a bug with Android version 4.1.3 (290). When selecting a conversation, Kontalk crashed. Same behaviour with all contacts, all conversation.
But notifications were steel OK, I was just seeing them when they were sent, and when clicking on it, app crahed.
So I decided to re-install Kontalk app (same version, the current one). I entered my phone number (same id) and selected "Lost my keys’ (or something similar, I didn’t remember).
My account was re-activated, everything seems to work OK, no more crash.
But all previous conversations was lost …
This is very sad, as I lost several years of conversation, including the ones with my wife which are the most precious for me ;)…
Did the re-installation purge all existing data ?
I tried to recover /data/data/org.kontalk to get the SQLite db file using adb, but backup is only 1ko with only a manifest file.
nb : phone is a Nexus 5, with Hammerhead, non rooted.
Thanks for any help.
