I have a question about how to do a wallet backup with this app. When I choose backup wallet, and confirm the action, a QR code is generated. Then I copy to clipboard. However when I paste this anywhere to save it, it pastes as a numbers/letters..ect. Now when I go restore from backup the app expects a QR code. How do I restore from the backup if the code is not pasting as a QR code in the initial step of taking a backup?
Your help is appreciated.
Thanks!
There are basically two ways you can do backup/restore
1. Take a picture of the backup QR-code with a secondary camera and print it on paper.
2. Copy the text value of the QR-code to the clipboard, and use an external tool to generate a QR-code from it.
When doing a restore, just scan the QR-code.
I have always used option 1. Copying it to the clipboard makes it available to other apps on the same device.
I agree that this could be somewhat easier, and I have been considering to add the option of writing the QR-code as an image onto the SD card of the device. However, so far I have avoided this as it would require BitcoinSpinner to have privileges to write onto the SD card. I am very focused on limiting the required privileges to the bare minimum, right now BitcoinSpinner only requires:
- Network Communication
- View Network State
This makes it easier for me when I have to defend BitcoinSpinner from paranoid users claiming that it steals contacts or tampers with your SD card etc.
I am open to suggestions.
