[Pharo-project] Does CogDroid work on mobile devices?

Caludia, I looked at the log you sent. [2427] after interp_init [3074] updateDisplay: Display width is 800 (expected 320) [3074] updateDisplay: Display width is 600 (expected 202) - this is a typo as I found - this line should say "height" says that interpreter was entered, and even tried to update display. I don't know what exactly your phone specs are (cannot google this specific model but Samsung 5500 with other letters mentioned 128 to 170M RAM). How much RAM does it have? I tried CogDroid on x86-Android in a VM with 128M RAM. It started, but switching to home screen killed it (and logcat said the same*, killed because of low memory). Expect CogDroid to use 50M at minimum. So, if you also have some other applications running this may be simply insufficient memory. --------------- * Of course it is very easy to get root shell and run logcat on x86 Android since root console is simply there. On my tablet I cannot do this. -- Dimitry Golubovsky Anywhere on the Web

It installs properly, and recognizes the .image files on the sd card, but when I try to open an image it freezes up, and after a while > the application closes :( There may be a text file: /sdcard/jni.log left on your phone. If you can send it to me I may be able to find out something, at least at which phase it crashes. Although I don't know how easy is it to get it out from the phone. Do you have a file browser on your phone (sorry if I am too technical, but otherwise I just don't know how to help)? If there is no such file, it may be due to mainly two reasons: - Somehow the native library (VM itself) did not load - /sdcard is not the SD card mount point (the path to this log file is hardcoded). In the latter case I would be very interested to know where is SD card mounted A typical jni.log for a short session might look like this: [459906122] /mnt/sdcard/AndroZip/home/dima/src/cogvm/dmg-blessed/build/PharoCore-1.3.image /mnt/sdcard/AndroZip/home/dima/src/cogvm/dmg-blessed/build /mnt/sdcard/AndroZip/home/dima/src/cogvm/dmg-blessed/build/x [459906122] bigEndian = 0 [459906122] vmPath: /system/bin/ [459906122] vmName: /mnt/sdcard/AndroZip/home/dima/src/cogvm/dmg-blessed/build/x -> /mnt/sdcard/AndroZip/home/dima/src/cogvm/dmg-blessed/build/x [459906122] viName: /mnt/sdcard/AndroZip/home/dima/src/cogvm/dmg-blessed/build/PharoCore-1.3.image [459906122] documentName: (null) [459906122] about to init time [0] about to init image [0] imgInit /mnt/sdcard/AndroZip/home/dima/src/cogvm/dmg-blessed/build/PharoCore-1.3.image [0] /mnt/sdcard/AndroZip/home/dima/src/cogvm/dmg-blessed/build/PharoCore-1.3.image /mnt/sdcard/AndroZip/home/dima/src/cogvm/dmg-blessed/build/PharoCore-1.3.image [0] fstat(33) => 0 [0] extraMemory: 0 [0] image size 16109320 + heap size 20971520 (useMmap = 1073741824) [500] about to open window [500] after interp_init [8320] Interpreter entered: 40 times [8320] Alarm timer (T), msec: 200 [8320] Exited by alarm: 1 times [8320] Interpreter times, msec (min avg max): -1, 10, 230 [8320] Longer than 1.5 * T: 0 times [8320] Longer than 2.0 * T: 0 times [8320] Longer than 2.5 * T: 0 times [8320] Host times, msec (min avg max): -1, 184, 330 [8340] exiting for sure If you cannot extract it from your phone you may look at mine and tell me where yours ends.

Hi, Clara Allende wrote: > Dimitry, just curious... Does CogDroid work on mobile devices, or just in tablets? I want to try it on my android mobile phone :D I think it would work on anything with Android > 1.6. See http://code.google.com/p/squeakvm-tablet/wiki/TinyBenchmark People tried it on many different devices including phones. Screen size may be another story: on a small phone screen it may be a bit hard to work with windows that Squeak or Pharo provides. Can you attach your phone to a larger monitor (some phones advertize HDMI connection)? But properly written applications that use large interface elements would work just fine even on a small screen. You may try this old 3.9 image: http://squeakvm-tablet.googlecode.com/files/sqandr_pres.zip I altered its default theme to use larger fonts where possible. So maybe it will be better visible on a phone. Hope this helps. -- Dimitry Golubovsky Anywhere on the Web

[Pharo-project] MC load vs merge
by Camillo Bruni Oct. 1, 2011

Oct. 1, 2011

Hi everyone, I am improving the way the Monticello UI handles conflicts when doing a load. Right now you just get a warning which lets you decide whether to overwrite the local changes or simply cancel the action â a merge action is missing! I added the marge behavior, so far so good, but there is a slight glitch: The conflict message is shown based on conflicts on the package level, for performance reasons. Lets assume that the loaded version only contains new classes for the package that you changed locally, you still get a conflict message although the changes can be loaded without problems. So my question is on how to load stuff in this case: - go the git/svn way and load everything if there are no conflicts - load everything if there are only added entities (not removals/modifications) - always show the merge/diff view to check what changed manually cami
