I recently used Mycelium and noticed that the instant payment feature (scan a QR code with an amount and up to a certain amount it will auto confirm) is gone! Why is that? It was one of the coolest features in the wallet. Please put it back, it makes paying for small amounts so much faster.

New version (1.0.5 I think) works perfectly on my DROID BIONIC (Android 4.1.2) and on an older HTC INCREDIBLE (Android 2.3.4)

Nice work. I like the new backup scheme.

One request - a Cold Store capability using an encrypted private key. (Maybe the plan is this will come with BIP38, but if that takes a long time to load on a phone maybe a version with a faster set of SCRYPT parameters could be considered?)

The format used by the encrypted PDF backup already works with the Cold Storage Spending feature.  Smiley


Oh. I hadn't tried it. I hate carrying the password in my pocked with the encrypted key but I guess I could write down 10 of the characters of the password and memorize five of them.

Thanks Jan.

the new version has solved the scrambled screen problem on my huawei :-)

good to hear! i disabled screenshot protection for all 2.3 devices. eventually we can build a list of known-positive devices where i can re-enable it (for example my HTC DHD on CM7 does support it)

Great work on the new version! I had a problem with verifying my backup. Tried to use the clipboard method, and no matter how many times I copied it to the clipboard, the button remained "gray". Besides that, great update.

does importing the key from clipboard work?

I´d like to be able to simply save the pdf backup on my sdcard in order to manually transfer it to my pc.
Is that going to be an option?

yes, it will be in one of the next releases. hours after release this is already one of the more frequent requests.

Awesome app.  Just wanted to bump the bip38 import feature.  I know it will be slow but it wont be done often..

Thanks again for this amazing program!

anyone has an idea where this might come from, we've had two of them:

someone clicked an item - "startActionMode" happens when you select a key or entry in the address book or transactions. but why a "division by zero" ?

also someone long-pressed a TextView.. hmm

update 1.0.5 pushed to play store, github, and mycelium.com which fixes the "scrambled screen issue" for all 2.3.x devices.

direct link until google activates it in 2-3 hours: http://mycelium.com/mbw-v1.0.5.apk

(this is the exact binary as pushed to play store, sha1sum 389743784a5629e591779abf33e68d498f1d697f ) , signed with the release key

though now it is possible to take a screenshot on those devices (which is unfortunate)

what are your android.os.Build.MANUFACTURER
How can I quickly determine the exact value without starting the eclipse-monster on my poor old laptop to compile a hello world app and print this constant?

maybe look it up here:

If it cannot be fixed, could you please make an option in the settings to disable that protected screen mode? I have tested the previous testnet version a few days ago and the key backup process worked just fiine (I assume this was without the new anti-screengrabber function?), I would very much like to keep this device for a while longer, although its at the lowest end in terms of performance and resources of the currently available devices I like it quite much, it does what I need and it is really small (unlike most of the other monstrous Android phones nowadays).

for now, i am disabling the secure screen feature for all 2.3.x devices, and enabling it only after it is verified that it would work. for that i need a setting and some data points from users, which will be added later.

what are your android.os.Build.MANUFACTURER
How can I quickly determine the exact value without starting the eclipse-monster on my poor old laptop to compile a hello world app and print this constant?

thanks for the feedback, prof7bit.

this screen is supposed to be "protected" against screengrabbers, so apps that could make screenshots cannot do so.

apparently, some devices have trouble with that.

do you have the same issue if you try to export a single private key?

on what android version/phone model are you on, exactly?


this is a Huawei Ideos X3 with Android 2.3.6

I have currently only one key and used the button on the main screen "backup missing". If I go into "keys" and select the one key that I have and "export" from the menu it shows the same symptom.

If it cannot be fixed, could you please make an option in the settings to disable that protected screen mode? I have tested the previous testnet version a few days ago and the key backup process worked just fiine (I assume this was without the new anti-screengrabber function?), I would very much like to keep this device for a while longer, although its at the lowest end in terms of performance and resources of the currently available devices I like it quite much, it does what I need and it is really small (unlike most of the other monstrous Android phones nowadays).

regarding the scrambled screen issue:
see here:

https://github.com/mycelium-com/wallet/blob/master/public/mbw/src/main/java/com/mycelium/wallet/Utils.java#L766

Code:
public static void preventScreeshots(Activity activity) {
      if (android.os.Build.VERSION.SDK_INT == android.os.Build.VERSION_CODES.GINGERBREAD
            && android.os.Build.MANUFACTURER.equalsIgnoreCase("samsung")) {
         // On some Samsung devices using android 2.3 we cannot use the secure
         // flag, as it makes the display scrambled.
         return;
      }
      activity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_SECURE, WindowManager.LayoutParams.FLAG_SECURE);
   }

we need to insert your phone model in this code to fix it. but what are your android.os.Build.MANUFACTURER and android version ?

some people suggested it is a problem on all 2.3 devices, but it works on my HTC with 2.3
