There is a newer version of the Android SDK; however, the older version is being used on the tablets. Why?

I looked it up a while back when I attempted to do all the work myself (didn't work very well lol). From what I can remember it had something to do with the framebuffer/kernel interface to it changed? I also read that it was possible of using the userspace of the newer SDK, but for some reason people generally don't.

• What can be done to port the newer SDK?
• What can be done to increase the speed of Android on the N800?
(it runs smoother on cells with lower specs, the 400MHz proc should be more than adequate for running Android)

Someone already got m5-rc15 running on n800 but not very stable. However, we can benefit from his stop all unneeded processes script

The problem is called RAM - already filled up with maemo.

EDIT: Just trying unloading the whole bunch of processes there - Android is much faster and responsive this way. If you want it before penguinbait adds it to the deb - just add this in

Code:

/usr/bin/android.sh

just after

Code:

echo "Starting Android..."

Code:

/etc/init.d/zzinitdone stop
/etc/init.d/alarmd stop
/etc/init.d/mediaplayer-daemon stop
/etc/init.d/bme-dbus-proxy stop
/etc/init.d/af-base-apps stop
/etc/init.d/btcond stop
/etc/init.d/dbus stop
/etc/init.d/gpsdriver stop
/etc/init.d/hildon-desktop stop
/etc/init.d/hulda stop
/etc/init.d/libgpsbt stop
/etc/init.d/obexsrv stop
/etc/init.d/af-startup stop
/etc/init.d/af-services stop
/etc/init.d/x-server stop
/etc/init.d/maemo-launcher stop
/etc/init.d/osso-systemui stop
/etc/init.d/bluez-utils stop
/etc/init.d/multimediad stop
/etc/init.d/mce stop
/etc/init.d/product-code stop
/etc/init.d/hildon-update-notifier stop
/etc/init.d/metalayer-crawler0 stop
/etc/init.d/esd stop

And by much faster i mean at least 5 times

According to the post - you should have lifeguard reset switched off.

Did you actually test this? It kep rebooting, then I did the lifeguard reset, and now it starts but the red line is not really moving. Its like its CPU is pegged or something? I need to get ssh on this partition.

more to follow

UPDATE, I just need to remember what kernel I am running??

hehe too much going on sometimes...

Yes, i tested it both from ssh and from the menu.

~~Looks like your lifeguard reset is still active.~~ Scratch that - something is hogging your CPU...

Not exactly sure if it 5 times faster, but its definetly faster. The only problem is that the only way to set no lifeguard reset flag,is on the linux flasher. I do stop some services for KDE, and I assume that many of the pieces can be shutdown but I think it would be better to come up with a list of as many as we can shutdown without lifeguard reset. So we can get it in as many hands as possible. We can also keep this around, to use for people with the reset flag.

Now I am off to see how this effects KDE?

hehe, I like it

OK, i'll start from the top and see how many I can kill before it resets.

All good up until:

af-services
x-server killed it too. This seems like a pretty big one, but don't you need the x server for android anyway?

maemo-launcher also killed it, this list is starting to get long

And thats it. The rest worked just fine.

So here's the final list

Code:

/etc/init.d/zzinitdone stop
/etc/init.d/alarmd stop
/etc/init.d/mediaplayer-daemon stop
/etc/init.d/bme-dbus-proxy stop
/etc/init.d/af-base-apps stop
/etc/init.d/btcond stop
/etc/init.d/dbus stop
/etc/init.d/gpsdriver stop
/etc/init.d/hildon-desktop stop
/etc/init.d/hulda stop
/etc/init.d/libgpsbt stop
/etc/init.d/obexsrv stop
/etc/init.d/af-startup stop
/etc/init.d/bluez-utils stop
/etc/init.d/multimediad stop
/etc/init.d/mce stop
/etc/init.d/product-code stop
/etc/init.d/hildon-update-notifier stop
/etc/init.d/metalayer-crawler0 stop
/etc/init.d/esd stop

OK, so according to qwerty, the x-server is not needed by android since it uses the framebuffer instead.

I also found that killing browserd frees up about 2mb of memory. Its hard to tell though since the numbers seem to jump all over the place.

Another way to improve performance is to go into dev-tools and disable window animations.

This works for me without any special changes for lifeguard

Code:

echo "Starting Android..."

/etc/init.d/zzinitdone stop
/etc/init.d/alarmd stop
/etc/init.d/mediaplayer-daemon stop
/etc/init.d/bme-dbus-proxy stop
/etc/init.d/af-base-apps stop
/etc/init.d/btcond stop
/etc/init.d/dbus stop
/etc/init.d/gpsdriver stop
/etc/init.d/hildon-desktop stop
/etc/init.d/hulda stop
/etc/init.d/libgpsbt stop
/etc/init.d/obexsrv stop
/etc/init.d/af-startup stop
/etc/init.d/bluez-utils stop
/etc/init.d/multimediad stop
/etc/init.d/mce stop
/etc/init.d/product-code stop
/etc/init.d/hildon-update-notifier stop
/etc/init.d/metalayer-crawler0 stop
/etc/init.d/esd stop

## These may cause lifeguard to reboot the system
touch /etc/no_lg_reboots
/etc/init.d/af-services stop
/etc/init.d/x-server stop
/etc/init.d/maemo-launcher stop
/etc/init.d/osso-systemui stop

rm -rf /android/tmp/*

This does make Android run much faster! Thanks for the tip
