brainblocks-android's Issues

REQUEST: Let users change amount to send

Add option to let the user change the amount using a drop down menu or a slider. Use full screen height & width to avoid clutter.

This could be done in another window/another screen but IMO the less windows the better the user experience.

edit: doesn't make sense if QR code doesn't include amount

REQUEST: Copy and share recipient address

Add a share button and allow the address to be copied to by clicking on the address or QR code.

Checkout dialog shows 120 seconds remaining when orientation changes

Checkout dialog says 120 seconds remaining when orientation changes. It gets back on track with the next tick.

1.0E-4 XRB instead of 0.0001 NANO

First of all thank you for your amazing work.

• 1.0E-4 is not user friendly IMO
• The amount to pay text is a bit hidden in the upper left corner. The font is kind of small even on my 6.4 inch device
• Still using XRB & Raiblocks instead of NANO & Nano

edit: title should say: instead of 0.0001 NANO

Recurrent Micropayments Possible?

I am trying to build an application which provides media content/stream on a per minute basis, I would like to take payments each minute, But i dont want the user to click on pay each time I ask for a payment. Is there any functionality where a user can set a max limit they wanna pay and the app can automatically deduct from the wallet?
Or something similar is possible? Any comment is appreciated.

Window disappears on configuration changes

The payment window is lost on configuration changes (like screen rotation).

REQUEST: Add option to add hash code for identification

It would be great to be able to check at any time if a payment has already been made from a specific user. This could be done by adding an option to automatically refund the sender/user a small amount (numeric hash entered by app developer) to the sender address. Kind of how the system works now when you overpay.

For example: user pays 0.1 NANO
He automatically get a refund of 0.000000000000000052505352525048 NANO or 52505352525048 RAW

That hash in combination with the sender address and user id could later be used to verify a payment has been made which would be pretty awesome.

The problem might be that the current nodes don't accept transfers that small.
