GAIA loves the Android wallet  :D

why so much for a compile?

Well it requires some c++ tweaks, in addition to tests on multiple devices :)

Well its deff cool i'll give you that. I bet it uses crazy amounts of resources as compared to the bitcoinj mobile clients. Have you done any comparrisons? I'm curious to know.

I haven't tested bitcoinj ressources usage, but qt wallet performs well on android, nothing excessive.

Also qt wallet has the advantage of having all the functions working like coin control and more :)

This is quite a bold assertion I would say. And one might speculate endlessly about why this is for such an exorbitant amount of BTC instead of releasing a slew of these onto the market for the greater good of the community? Perhaps releasing the method of the task so you do not have to take up such an arduous task of compiling each coin and that quite large favor of separating people from their cumbersome bitcoin at the same time.

Very interesting.  This provides a quicker way that what I do with bitcoinj/bitcoin-wallet.

I'm curious, did you manage to get both qrencode and miniupnpc compiled for ARM or have you decided not to implement them?

I'm skipping qrencode and miniupnpc for now, might give it a shot if it is necessary, but most coins do no use qrencode at all, nor miniupnpc on linux.

Nice service, yes direct Qt wallet compilation for android is a better solution in many cases, especially for PoS coins.

Could you make an andoid wallet which works locally on the phone as a light client that connects to your own web wallet? The idea is something akin to VNCviewer in which you would connect with your SSH keys to your node so you don't have to run the Blockchain and Stake and use resources on your phone. The problem I have with android wallets is that Staking and holding many different Blockchains uses up a lot of resources when it would be better to be able to connect remotely to your own hosted and secured node which holds the Blockchain and Stakes for you but to have the functions of use and the QT. If you were running POS on your phone then you could only Stake when connected when you want to be able to be connected, staking and synced all the time.

I had the same idea, but accomplishing this would require some major changes to how the code handles the blockchain database. Not sure if it is worth it as with modern sd cards, disk space is cheap.

Yes but it only allows you to host a small amount of different Coins on any one phone, if you had 5-6 different POS Coins on an android phone Staking, updating Blockchains and the average chain was 1 gb then that is 5-6 GB of space along with the resources required to constantly sync and run those wallets and that would drain your battery and resources very quickly. If you could connect to your own hosted wallet then you could host the chains there, or on several different nodes and the space, CPU requirements and Staking would be handled there with near 100% uptime so you could then connect to different nodes you control which may host 10-15 Blockchains each at $5 a month per node hosted, then you are only using and controlling your nodes from your android without consuming the resources and could manage 30-50 different Coins without any impact on usage.

I did some work last year where I connected through VNCviewer to a Linux node and would be perfect if using additional security of SSH keys and multilayer-security in order to connect. The only issue I had was being able to use it properly on a touchscreen since it's made for a desktop so was very cumbersome to use. If doing an android wallet traditionally, you need to constantly rebuild the wallet whenever doing updates, it would be better to more or less use the system by viewing it and manage updates through Linux which is the standard for building.

Well looks like what you need is an rpc client to connect to your remote staking nodes, it can be done over https for more security. No need for an android wallet in your case  :)

how about security owned by android wallet qt so far? whether toughness similar to those of the PC?

Security is the same as the desktop linux wallet with compilation securities like buffer overflow protection, and also user security as the wallet offers the same encryption options as the desktop client to encrypt the wallet with password.

Other java/javascript android wallets are less secure than this one.

How long does it normally take to do the android wallet?

2 to 4 days depending on my work load.

Great, I'll get some BTC together, do some checks with the source and let you know once I'm ready :)

Sounds good, thanks :)

Have you done Android compilation with Coinami? https://bitcointalk.org/index.php?topic=713649.0

The issue I have with an android wallet would be holding the entire chain on your phone so over time it would consume a fair amount of resources. Coinami is open source and uses an electrum server to create a lightweight client. Is this something that you think you would be able to do?

If that is not possible then just the standard client would be fine, I have BTC available for the work.

I only offer the standard client for now, I will offer a solution similar to coinomi soon, including iOS support.

With modern phones, storing the chain is not really a big deal, also as shown in the pie chart posted before, the ressources usage is very reasonable, but the standard wallet offers some features coinomi doesn't like wallet encryption, backup and more.

I have tested this wallet with coins that are more than a year old and it works fine. Thanks!

Fantastic work!

GREAT service, quick and great communication.

I highly recommend this service for your Android needs.

arent the chains too big for exact QT copy?

Not with the new phones/sd cards, most chains are < than 1 gb.

Hey sakr. Recently we had a takeover on Transfercoin and a new wallet released. I was wondering if a follow up build would be any cheaper? You can PM me any details if you don't want to make it public.

Yes, for simple rebuilds it's 0.1 btc, can be more if the build has many changes and requires a lot more work. Thank you!

looks very cool
can it read QR code with the camera ?
and.. if i pay for this service, will you give me the modified source code ?

The build is the same as the desktop wallet using the same source so it does not include a QR reader, but a generic QR reader can be user to read QR addresses and past them into the wallet.

Also the source code is the same, with very few changes mainly layout ones.

Looking great, good job ;)

sakr, did you get the hosting service up and running yet (Similar to Coinomi)?

I offer compilation of Qt wallets for android, not Coinomi like SPV wallets, the Qt wallet does not require hosting, it's the same as the desktop Qt client.

I ws mainly curious if you had made any progress with getting your service ready. Should I assume you have no plans to offer this still?

What devices do you test your wallets on? I have a Samsung S5 for example, and the Transfercoin wallet is majorly bunched up to the point it is not useable. Is there a way to have the wallet resize itself for difference devices?

I do not offer this service publically yet.


I test on many devices including Samsung phones, also on different Android versions, however some phones have some specific text zooming features, which are not standard to android, and which Qt android does not recognize so the display is messed up on those devices. but the wallet works on the majority of devices as it have been reported.

I wonder if you tested with the latest build for transfercoin, it might work better on the S5 as it uses a newer Qt version an also some GUI improvements have been done.

I made a crowdfund post for this, id just like to know isnt clam getting a bit too heavy to be on the phone? Is the whole chain going to be hosted on the phone?

Clam blockchain is around 2gb, it should work well on modern phones with enough memory to hold the chain either on the phone memory or sdcard, yes the android build is the same as desktop one, the whole chain is going to be stored on the phone.

i downloaded transfer app and it is not as the provided images.

here is what i see :

Hi Sakr,

I will pm you regarding options thanks
