I took a look at the apk and noticed this in the manifest. "com.blockeq.stellarwallet.WalletApplication" Stellar Lumens is a fairly popular crypto currency. I wonder if the app has built in support for crypto transactions. If not, maybe it's malware to mine crypto coins.

It is a crypto chat application:

>Ravn is your portal to the most private messenger as well as Korrax our proprietary token. Stay up to date with Korrax and other Cryptos and join the crypto group chats.

>Messages, images and docs are never stored on a server (after delivery), they’re only locally stored on your own phone. Ravn is not tied to your phone number or email, you only sign up with a username that isn’t searchable or discoverable.

Stupid question: how did you reverse the app in Android Studio?

[catlover99]

I downloaded the APK and then used "Profile or Debug APK" under file in Android Studio and ctrl/cmd+shift+f to search for strings.

I don't know much about Android development or APKs but it's not exactly "reversing." from what I understand the profile/debug converts the .dex files from the APK to .smali which is human readable.

You can use the "Analyse APK" feature, but you probably rather want to use tools like jadx or apktool that provides fairly good decompilation.
