Thanks.  My guess is that either the apps need a GPS present,
regardless of whether it is on or off, or they are using display
features that aren't present.

Hi

Installed c:geo (geocaching app) gps essentials and osmand (open  
street map). In all cases some or all of the screens display blank,  
all black. One thing they have in common is that they display maps.  
Another is that they use gps data when available, they should still  
work with no gps, I expect, because they will work on my phone with  
gps turned off.

Thanks, yes, that's what it looks like.  I don't think it is reliable

predictable.  See commend in olpc-sd.rules in dracut-modules-olpc.

Looking at olpc-boot-cmdline.sh in dracut-modules-olpc, we use
/dev/disk/mmc references instead of the legacy /dev/mmcblk references.

no clear idea, just hasn't been studied.  the first blockage was an
old olpc.fth was used in the latest build by ben, because my git repo
fu was pathetic, and it was hard coded to use int:\ for the icons of
the menu.  the menu had actually been moved into the firmware.

subsequent blockages probably have to do with identifying the
partition to mount, avoiding mounting the internal partitions, and
dealing with keeping the external partitions mounted over suspend.

Re: Announcing another early Android build for XO-4

[Scott Chapman]

When I installed the Android build on my SD card and tried booting Android,
I got this error:

ok: :151 error opening icon file

So i can't even install it on the SD card to test, with or without the
Linux OS. :(

This does make testing painful.  I think would be well worth while to get
this to work if it's not too much effort.  It would make people a lot more
willing to do testing and play around with it.

is it possible (read: "has anyone tried") to install just the
android half of these releases on an SD card?  then dual booting
would just involve inserting or removing the SD card, and trying
new builds would be a lot less disruptive on the linux install.

(i realize this isn't the target configuration, but it might get
some additional testing coverage.)

I needed to use glasses for best reading of that text, but I am not
the target market for the device.  It needs testing with a child.

I agree.  I don't think there is any standard that the browsers must
comply with for the size of text.

http://dev.laptop.org/~quozl/android-2014-04-25/shot0019.png is a
microscope photograph of the age column of the file list shown by
Chrome.  The text is "14 days ago", and at this magnificiation you can
see very little contrast.

http://dev.laptop.org/~quozl/android-2014-04-25/shot0014.png is a
photograph of the README text.  Still, the contrast is not as much as
it could be.

I did these shots to see if I could find any evidence of mistakes of
subpixel hinting, which may assume a different layout of the LCD
pixels.

The choice by Github to use such a low contrast is unfortunate, but I
don't know of any way to adapt to that in Chrome in a fashion that
won't break other sites.

Chrome is needed by our customer for this build, so we have
considerations other than font readability.  I'm glad you can choose
an alternate browser.

You can't really miss the response to the keys; it is noisy with
visual animation.

If you see a volume control bar appear, you pressed the keys in the
wrong order.

http://wiki.laptop.org/go/Android/Screenshots updated with:

To take a screenshot on an XO-4 with Android:

  *   press the power button and then X game key and hold them for a
  second, then release,

  *   a sound is played, and an animation of the screenshot,

  *   the screenshot is available in a file browser or gallery,

It won't work if the X game key is pressed before the power button.

Obviously your eyesight is better than mine but this is not the point.
In this picture [1] from Github with Boat and Chrome browsers at 120% text 
zoom, you can see that the README text is at comparable size but everything 
else is smaller in Chrome and actually the same size as at 100% zoom.

BTW, how did you get the screenshot? The Power-Button+X-gamekey does not appear

I've no idea which one it was.  I've just tested Chrome on this build
with github.com, going to one of my Arduino repositories, visiting the
origin of the fork, reviewing two patches and displaying diffs.  I
didn't find it unpleasant, and the font size was reasonable.

No.

You can use the Gnome build or Tiny Core Linux to explore the
filesystems of two builds and compare them, or you can unpack the .zd
file using zdextract.

Chrome is failing to enforce minimum font size in various sites (try github as

Announcing another early Android build for XO-4

[James Cameron]

An Android 4.3.1 (Jelly Bean) build for the XO-4 laptop.

OLPC is preparing an Android, Sugar and Gnome dual-boot system for the
XO-4.

Our next development build is available, with the following changes:

- camera recording is working,

- Chrome as default browser,

- improved keyboard mapping,

- the rotate button invokes the Android apps switch,

- the hardware codecs are working,

- movie editor crashes fixed,

- boot menu integrated with firmware, and no saved boot choice,

- idle sleep,

- power button sleep,

Note: to boot into Android now, you must hold the O game key, or
hold the rocker down key.  The boot choice is no longer saved.  This
is so that laptops are not forced off when the saved state is
inconsistent with the user's expectations.

The build is based on our arm-3.5 kernel, with changes which will be
found in the arm-3.5-android branch of our olpc-kernel repository.

http://wiki.laptop.org/go/Android
http://build.laptop.org/android/2014-04-17/

Hi

I could not find Settings, Developer options but I did find Settings,  
System, Accessibility, Magnification gestures which by default is off.  
Turning it on enabled pan and zoom.


Not sure but it seems that you need to tripletap first and then pan  
and zoom are available, pan seems to require two fingers. Works in  
home screen and browser.

It correctly shows one, two, or three touches.

Nice work.

I think the touchscreen driver is busted.
Open Firmware tracks two or three fingers nicely (if one avoids
occlusions in X and Y), but multitouch test apps in Android
confirm what I saw when trying to use Google Maps -- multitouch
is currently broken in Android.

Are bugs being tracked in Trac ?

This is a disturbingly nice build!
When video recording will also work will be great.

Tested bluetooth connection to an iMac with no issues (file transfers)


It would be nice if the screen rotation button could be used to block screen 
rotation.

the power button does produce real down/up events, but until today,
when we released new EC firmware, both down and up came right
together, independent of how long the button was held.  plus, the
power button appears on a different input device than the rest of the
keyboard, which shouldn't confuse things, but might.

the new EC code produces real PRESSED and RELEASED events which the
kernel now translates to to real key down/up input events.  ben needed
this for the android power dialog, which relies on timing the button
press duration in order to pop up the menu.  it's vaguely possible
that this change also fixes the screenshot combo.


Thanks, John and Paul.

As Paul said new EC code generates real PRESSED and RELEASED events for 
power button now.
But it doesn't fix the screenshot combo. I suspect it because the of the 
Volume down button is actually
inside the keyboard, It doest not produces real pressed and released 
events when long pressing instead

of produces a sequence of fake pressed and released events.

BTW:

Does anybody has any suggestion about what we should mapping these 
buttons on XO-4 screen pad in Android
system? For example should we mapping a button switch between LCD color 
and mono mode?


Thanks,
Ben

Probably something to do with our power button going through the EC,
and not being directly sensed by the MMP3 SoC.
Power button events thus come in over the EC/Host communications ---
I'm not sure these are button down/button up events.

Android brings in a hot key combination for screenshot which is press 
the hard volume down and power
buttons at the same time, hold them for a second. But unfortunately it 
does work on current XO-4 build.

Need more investigation why.

As a alternative there is a binary which can do the some thing via adb shell

adb disconnect && adb connect 192.168.XXX.XXX
adb shell screencap -p /sdcard/screen.png
adb pull /sdcard/screen.png

Does this build has root access on the Android side?

Yes, it has.

It's a userdebug build which means If you use adb shell, su is still 
available to gain root privilege.


more detail please go to this page see the difference of Build Variants.
http://www.kandroid.org/online-pdk/guide/build_system.html#androidBuildVariants

But because it's a standard "su" come from AOSP project. It only allow 
process raise privilege if

it has shell or system uid.

If someone can port a customized cyanogenmod "su" to this build. It can 
have full root access

for all the applications I guess.

oh, okay.  sorry for the noise.  the 2/26 release was the first
i'd installed.  i just assumed the filename would change for the
next one.  but of course the versioning issues are very different
with two OSes, one of which may be versionless, for all intents

the imagename (32013a4.zd) hasn't changed from the 2/26 release.
the md5 sums are different, so i guess this is probably just a naming

Announcing another early Android build for XO-4

[James Cameron]

An Android 4.3.1 (Jelly Bean) build for the XO-4 laptop.

OLPC is preparing an Android, Sugar and Gnome dual-boot system for the
XO-4.

Our next development release of a dual boot build is available, with
the following changes:

- a boot menu, if the rocker down key is held during power up,

- the touchpad works,

- power management works,

- the automatic partition resize no longer requires a first boot into
  Linux,

- switched to user build from engineer build,

- the power button menu will work once new firmware is released, which
  should be tomorrow.

The build is based on our arm-3.5 kernel, with changes which will be
found in the arm-3.5-android branch of our olpc-kernel repository.

Problems observed with this build:

- incompatible with 4GB eMMC, only with 8 GB, my mistake in the
  mkzd.sh script used for image preparation,

- incompatible with the Marvell 8686 Wireless LAN card, perhaps
  because the driver was not built as a module, and our kernel
  developer didn't have one of these cards.

Announcing another early Android build for XO-4

[James Cameron]

An Android 4.3.1 (Jelly Bean) build for the XO-4 laptop.

OLPC is preparing an Android, Sugar and Gnome dual-boot system for the
XO-4.

Our next development release of a dual boot build is available.

The build is based on our arm-3.5 kernel, with changes which can be
found in the arm-3.5-android branch of our olpc-kernel repository.
