ok i think this is it: Proscan 7-Inch Tablet with Google Android 4.1 Jelly Bean, 1.2GHz Processor(appearently it goes slow as the dickens),

I checked out stu's github code onto my Ubuntu 13.10 AMD64 box. (I used openjdk-7 instead of 6 but followed most other instructions in build/android/README.txt.)

First issue: I get the following error message running build.sh:

Code: Select all

It's still compiling, so we'll see...

EDIT: Now I get

I skipped the ADB step in the README, but followed everything else. Is running 'android update project' the right fix?

EDIT: NO, just had to define ANDROID_HOME env var.

Now I'm stuck at

EDIT: Which I solved with

Code: Select all

apt-get install lib32stdc++6

And now I apparently have successfully built the APK and I can load it into an Android 4.1 Nexus 7 emulator session. Unfortunately segfaults on the emulator. A problem for another day... (I wouldn't be surprised if it was related to the failed patch application -- there was quite a bit of code there)

EDIT: Here's some logcat

EDIT: OOH dopey error, forgot to add SD Card storage to the emulator. Now it runs but the result is a garbled menu (maybe OpenGL emulation in the emulator) that I can't interact with. None of the interaction works (probably the broken patch...) when I install to my phone, but at least the menus render correctly. I'm bowing out for tonight.

Sorry for the monologue, but maybe its useful to someone.

Same problem here with the current svn sources, try using the pre-patched sources from here instead.

Code: Select all

cd deps
rm -r irrlicht
git clone https://github.com/freeminer/irrlicht-android.git irrlicht

Works for me ;-)

Thx. I will try that. Anything that I can help with such as testing or features? I was going to try tweaking controls initially. Getting sound working is probably beyond me.

You could try cherry picking some of the updates from the freeminer android branch (which this was originally based on)
My biggest problem right now is lack of native debugging (android issue: 58373)

Re. sound, I have been looking at the following two repos, though Ive not really had time to try anything yet.

https://github.com/AerialX/openal-soft-android
https://github.com/vincentjames501/libv ... gg-android

The new version works very well with the chat button - the keyboard can also be removed again without going back to the main screen first. All that's left to do there might be some additional controls (chat history, perhaps screenshot).

Unfortionately, fps have dropped compared to the first version. Now, I get around 1 fps at VanessaEs Vanilla server at spawn and can barely move there. Other areas are less problematic. Similar fps drops have occoured on the much more complex servers in the past with older versions of the desktop version. Even in other situations, fps now seem to be more around 20.

I don't think anything added recently should cause a drop in fps but then I was kinda thinking the same myself...
The only thing it can be, If anything, is the soft-keyboard workaround. I think, in future, the hide button should only be redirected for effected versions. Those using 4.1 or 4.2 will just have to use the home or recent apps button trick to get rid of the keyboard.

Edit: You could try restarting your device, for some reason that seems to help for me. (possibly leaking memory somewhere?)

Edit: Here is an experimental build using xyz's irrlicht fork and without the soft-keyboard patch

Removed! It was bugged anyway.

Note that hiding the keyboard will cause the app to crash under android versions 4.1 and 4.2

New build: Minetest-debug.apk

Incorporated some updates from the freeminer android branch

Fixed lighting and some UI improvements (still needs some work with this stupid keyboard issue)

Good stuff. Can now get the "escape menu" on the Galaxy Note 2, which is nice. Got crash on exit though. I think I bought up the chat menu but not sure how and no keyboard.

Still have issue that screen needs new touch input to maintain an interaction (e.g. walking, punching). E.g. punching stops unless I move my finger a little as I do it.

I do too, seems to have something to do with server disconnection.

I think I bought up the chat menu but not sure how and no keyboard.

I am guessing that you can't see the chat bubble in the upper right corner of your screen?
If not then delete your current sdcard/minetest dir and run the app again.
Note that it will take longer to load and you will lose any settings.

If you wanted, however, you could simply copy in the missing cpad image ;-)

Without any debug info I can only guess that you have the same problem as VanessaE, I will look into this some more over the weekend.

Meanwhile, in the latest build, I have gone back to the original short-tap for right click / placement, though I think we do still need to have a button for left click / digging. I am mostly thinking of FPS mods like firearms but I'm sure there will be other cases where long press digging will be problematic.

ok um then how on earth do i run minetest with the adb logcat command

Updated

I've added some buttons for freemove, drop and debug info (F5), their visibility can be toggled using the 'double ellipsis' button in the bottom right corner.



Unfortunately, without proper debugging, this is as about as far as I can take this for now. I hope that we can get an official repo sometime soon where I can just submit PR's and report issues.

If any of my humble additions can be of any use to an official release, licencing is as follows.

Source code: Same as Minetest
Textures: CC-BY-SA (All 100% my own work)

This is really great work stu! I have a feeling you really made Minetest portable possible much earlier than most people expected. I hope this will flourish. +1

To get adb you need to fully install android SDK on your PC - Google it.. adb is one of the command line tools in the SDK and you can use it to talk to the phone/tablet via USB (after enabling developer options and USB debugging in your phone settings - Google it). When you run adb logcat you will see on your PC the live debug messages being generated on your phone (or you can dump the output to a file). So you can run logcat on your PC then start Minetest on the phone/tablet and you should get a dump of minetest debug messages and any crash messages.

Hi guys! I found a few bugs.
* does not load the list of public servers and mods;
* 't save settings;
* how to fly?
* I wanted to add your own textures, but they are not unpacked. I thought, you can write java script unpacking/scanning of files, then running the game. It would be easier and the progress bar is needed!
* languages. The game in English, regardless of the system language.

[sfan5]

* does not load the list of public servers and mods;

stu needs to compile with CURL support

* languages. The game in English, regardless of the system language.

stu needs to compile with GETTEXT support, additionally there needs to be code to set the ui language to the system language.

[MoNTE48]

You can compile Minetest to meet these requirements?

Thanks, though the real credit should go to xyz, all I've really done is add a few icons and make an apk.

stu needs to compile with GETTEXT support, additionally there needs to be code to set the ui language to the system language.

While I can get it to build fine with cURL support, it crashes the moment I try to show the public server list.

LogCat output is not really helpful to me https://gist.github.com/stujones11/9219104

regarding GETTEXT, I am not sure that is even possible?

A new binary would be great! Compiling for Android isn't that easy...
