hello

[marcelklehr]

hello there,

I was searching for (open source) mindmapping tools for android and came across your repo. I'd love to be able to edit my mindmaps both on android and with xmind on my desktop.

So, how are you coming along? Is there a demo build available already? ;) I'm afraid I'll probably not be of any help. I've never developed for android before...

[michalrus]

@marcelklehr Hi!

This is (so far?) a proof-of-concept project for a B.Sc. paper to test Scala-on-Android development. The strongest emphasis was put on real-time collaboration features and offline synchronization of maps between devices (which work quite nice, by the way).

When it comes to the "view", it lacks almost all features of XMind except for actual raw mindmap tree editing. So: no custom relations, no icons, no colors etc.

Here, have a look:

[marcelklehr]

So, it supports real-time collaboration?

[michalrus]

@marcelklehr It does, indeed. And synchronization of changes introduced while offline, too (with automatic conflict resolution). Pretty cool, if you asked me. <3

[marcelklehr]

woot! That's amazing. How complicated is the build process? I'd like to give this a try.. :)

Btw, how does real-time work? Via internet?

[marcelklehr]

You gotta upload this to http://f-droid.org, btw!

[michalrus]

@marcelklehr Feel free to do it. :3 Building could not be simpler, see for yourself, I've just updated the README.md.

(after downloading a lot of stuff)

[michalrus]

@marcelklehr Ahhhhhhhh, I'm so sorry! It should be:

$ cd agh-mindmap/android/

README.md updated, thank you! agh-mindmap contains both android project and akka server-side daemon. So yes, it works via network.

[marcelklehr]

Mh. Still doesn't work for me.

[michalrus]

Ah, Windows. It's a bug in SBT, create the XXX\.sbt\0.13\staging\e7af982aa8e832ae6622 directory by hand. :3

[marcelklehr]

Do I also need some Android SDK?

[michalrus]

Yes, yes, to build, run, communicate with the phone etc. I thought you had it and were asking how to build a Scala app. :) Still, this should be straightforward: download the SDK, unpack it and set appriopriate ENV variable. I don't remember its name, SBT will tell you, though.

[marcelklehr]

Doh, installed the sdk, now I get

[warn]  ::          UNRESOLVED DEPENDENCIES         ::
[warn]  :: com.android.support#support-v4;18.0.0: not found

Although it's clearly there.

Additionally, it throws a java.lang.RuntimeException: Platform android-17 unknown

[michalrus]

@marcelklehr Almost there! :+1: Start $android_sdk_directory/tools/android (the "SDK Manager") and make it install/download Android API level 17 and the support-v4 library. I don't remember the exact names, but you'll most probably manage. :)

[marcelklehr]

"Building could not be simpler" :P

It's prolly crazy of me to go through with this on windows..., but I'm almost there anyway, so.. meh. ;)

[michalrus]

Haha. ;3 Well, it could not be simpler if you had Android SDK installed, as I had assumed.

[marcelklehr]

hah, now I gotta install the java SDK, too. lol... not your fault of course :)

[michalrus]

Haha. ;3 So many assumptions on my part.

[marcelklehr]

ok, now I get java.lang.RuntimeException: no devices connected

What should I do to my phone to get it recognized? :)

[michalrus]

@marcelklehr Great, so the app builds. <3

It depends on the phone. Basically, you've got to install ADB drivers. You should have your phone listed when invoking:

$ android-sdk/platform-tools/adb devices

First of all, turn on USB debugging in Phone Settings -> Developer options, maybe it will work OOTB. If not, try generic ADB driver from Google in android-sdk/extras/google/usb_driver. If this one doesn't work, just google "adb driver windows $your_phone". ;3

[marcelklehr]

[success] Total time: 31 s Wooot! Now, that was easy... Thanks for bearing with me! :D

App is started. And I already have a few mindmaps..

[michalrus]

@marcelklehr My pleasure. ;3

Yes, no user privileges are implemented (yet?). And so everybody sees everybody's else mindmaps.

[marcelklehr]

oh. so I can collaborate with you, now?

[michalrus]

Yeah, basically. Don't mind weird sizing of the nodes, this will get fixed soon. ;3

[marcelklehr]

That's nice. Now I gotta get some rest... :)
