Another thing I can't believe I missed; why isn't there a sendmany type option to include multiple outputs?

Thanks for your support

Don't worry about the UI falling behind. We do have grand plans to overhaul it.
If you have any specific suggestions or something is bugging you, please don't hesitate to post here or write to developers@mycelium.com


if you want to see the early beta builds you need to join the google group AND activate beta builds at https://play.google.com/apps/testing/com.mycelium.wallet

just beta or normal work this?
this posible backup or restore?

We are very keen on keeping the UI simple while being rich on features. This means making many tough choices. Sendmany is IMO a feature you would rarily use on a mobile wallet, actually you are the first one asking for it.

Mycelium has been out of beta for some time now. Beta testers now receive updates some days/weeks before everybody else. Everyone can join the beta program.
Backup/restore? Yes, since the very first version. Most notable features shown in this video: http://youtu.be/G8FmwbgJuLM

I think it's funny I'm the first. Maybe you could use expert mode to add features like these so normal users don't need it. Can't it just be in the send menu? I think a good spot for it would just be a little plus sign on the screen you input the amount on, somewhere around the send button.

I am very pleased to announce that Rassah has joined the Mycelium team as our Community Manager!

One of Rassah's main tasks will be to guide Andreas and I to create an even better Bitcoin software based on community feedback (and common sense )
As a team we will hopefully be better at providing timely feedback and guidance on how to use Mycelium while getting more time for developing great stuff.

I noticed a small bug; when scanning a qr code for sending with amount=0.0892, the amount sent was exactly 0.089, so it seems amounts gets rounded somehow.

(Wrote this here since apparently Google now requires google+ for commenting in play store).

Thanks for the report. I am unable to reproduce this.

I have made a payment request and sent it to myself in an email like this:
Tap Receive -> tap the keyboard icon -> enter 0.0892 -> Ok -> Share Payment Request -> Gmail -> my email address

Result: bitcoin:1BoBsT2QicxGf3eroqcaXTwz9qaYiZZSNC?amount=0.0892

I have turned the string into a QR-code: http://imgur.com/KJnqj3H

When I scan it I get the correct amount 0.0892

Here is the transaction i sent: https://blockchain.info/tx/51096ef74647dd692b2bb64c88f0b9ff1b87fc231daf1ba3533ed771f9ae5043

If you can reproduce the bug please send me a copy of the QR code you scanned.

Which app was the QR code created with, Mycelium, or something else?

Hmm i paid something on a website, but I can't remember what it was. I had the qr code in my qrdroid history though.
The qr code text in history is: bitcoin:1GTWuwvEMVLGSWCBgZcnBkBqS9AQER1RF?amount=0.0892
..I guess that is according to the the standard.
Look at that address and you'll see both the original transaction from the qr code and the 0.0002 top up I had to make.

Edit: The qr code was from chunkhost.com

What? Since when? Where am I? What's going on? Wow, I must have REALLY partied hard at the Miami Conference

I didn't see anything about "common sense" in the contract. I reserve the right to use such a thing very sparingly.

Bring on the hoards of questioning newbies and scathing trolls, for I am ready to battle!!!

Congrats, Rassah! It's great to see more and more bitcoiners make the move from hobby to pro

[RGBKey]

Nice! Great to see the team growing!

[apetersson]

and we want to grow it further:
there are still two open positions posted to work with us on this great platform:

Question:  I have an app that allows users to buy things from my store, how can i interface with Mycelium for payments?   Is there an API or something?

[Rassah]

Version 1.1.6 is out. Get it on Google Play or direct download

Update includes:

* Support for btc-e
* Danish translation
* Some minor bug fixes.


I'm learning more and more about this awesome wallet software, and have been using it as my main wallet way before I joined this team (I think I started using it as my main back in August?). This thing is like bitcoin: fairly basic at fist glance (just digital cash), but has tons of features when you start digging into it. And the team is working on some really exciting new features that we'll announce in the near future. Also, I'll be creating some instructional videos about the wallet's more advanced functions over the next few weeks, but in the mean time, feel free to ask me any questions (I'm even happy to answer ones that aren't related to Mycelium  )

First, please test this using our testnet builds.
of course,there you must use testnet addresses.
https://play.google.com/store/apps/details?id=com.mycelium.testnetwallet

the code samples were written without running them once - so there might be an error


The most straightforward way to do it, is create a bitcoin uri.
see https://github.com/bitcoin/bips/blob/master/bip-0021.mediawiki

for example bitcoin:15f3mXNSY1oBnhaZDb7ifEYJvfg62XTtYe?amount=0.12345678
(we currently ignore label and message, this is a planned feature)

next, you send out a URI intent

Code:

String uri = "bitcoin:15f3mXNSY1oBnhaZDb7ifEYJvfg62XTtYe?amount=0.12345678";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(bitcoinuri));
this.startActivityForResult(intent,SOME_RESULT_CODE);

after a successful transaction you can check the transaction id in onActivityResult

Code:

String transaction = data.getStringExtra("transaction_hash");

i just wrote a full sample for you ready to copy-paste.
also, note that the same code should work with any decent android wallet, it is not mycelium-specific
(note: this should go into the FAQ)

Code:

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class SimpleBitcoinIntegration extends Activity {

   private static final int MY_RESULT_CODE = 2;

   @Override
   protected void onCreate(Bundle savedInstanceState) {
      
      //todo create UI as usual
      
      Button button = (Button) findViewById(R.id.btSend);
      button.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            String bitcoinuri = "bitcoin:15f3mXNSY1oBnhaZDb7ifEYJvfg62XTtYe?amount=0.12345678";
            Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(bitcoinuri));
            startActivityForResult(intent, MY_RESULT_CODE);
         }
      });
   }

   @Override
   protected void onActivityResult(int requestCode, int resultCode, Intent data) {
      if ((requestCode == MY_RESULT_CODE) && (resultCode == RESULT_OK)) {
         String transaction = data.getStringExtra("transaction_hash");
         Toast.makeText(this, "received bitcoins with txid: " + transaction, Toast.LENGTH_LONG).show();
      } else {
         //something else happened..
      }
   }
}

IS there an OSX update? thanks 

[TheButterZone]

Mycelium is an app for Android only.

[RGBKey]

Could you make it so that the keys section is able to be rearranged? Like, I want my addresses in there to be in a certain order because I have multiple watch only addresses in there, and it's annoying to have to reenter everything if I want to put something before it. Would like feedback on this, thanks.

[Newar]

How about integrating a "Tip" button?

[MarcoPon]

A small thing but... an audible notification when bitcoins are being received be nice feature.

With a possibility to switch it on/off of course :-).
