Android app for ammo inventory

[baekacaek]

Anyone tried using a technology called "pen & paper" ?

Paper ... or even an Excel spreadsheet, regularly maintained, seems faster.

Never heard of it. Is that an app I can download?

Local data. So if I upgrade, destroy or lost my phone, guns and ammo in a boating accident I loose all data? Still have to keep spread sheet updated...

Happened to me. Upgraded my phone, app installed during transfer but data didn't. Have to re-input everything.

I downloaded it last night but I dont think ill be able to use it. It looks well done but it would take me 4-5 days to input all my info into the app...... aint nobody got time for that

Google drive backup as an option for those of us who don't mind uploading to the cloud would be great. Password protecting/ encrypting those uploads would be even better.

So other apps or processes that access storage are they able to see this or read this data?

Short answer: yes (for the CSV file) and no (for app data/database).

Long answer: There's two storage in play here: one specific to the app, and second "shared" storage, or external storage. The app specific storage is protected by Android OS so that only that app can access it. The external storage is shared by all apps, so any app that has access to "external storage" can read it. The app will save all data in a database and store that database in the app's specific storage. No other apps can access it, unless you have a rooted phone. When you decide to export the data, the app will create a CSV export file and save that to the external storage, so that you can hook up your phone to your computer and copy it over (or send it over email, etc). So the CSV file is readable by any app with "external storage" access, but not the app's database.

Can you encrypt or protect this data? Something like a Keepass for ammo?

I can add a feature to keep the database encrypted, but for it to be true encryption, I would need to prompt the user for password each time the app is opened; the user's password would then be part of the encryption/decryption key used to decrypt data from the database. I personally hate passwords, especially because I have to remember a billion of them. So I didn't think this added inconvenience was worth the small gain, especially since Android OS already does a decent job at protecting an app's data.
