Hi there. This is kinda rhetorical, kinda not. I am experimenting with disabling apps, and have narrowed the Tesco installed apps to a few, and I wonder if someone else could confirm this.

 

 

Got some guidance here: http://forums.androi...remove-big.html

What I did was:

 

Rooted hudl, then...

 

 

Got a shell

adb shell

Got root access to shell

su

Remounted /system as r/w

mount -o remount,rw -t yaffs2 /dev/block/mtdblock7 /system

Got to /system/app dir and did

ls

The apps I seem to identify as not needed, are marked in red

 

matt@i3-550 ~/adt-bundle-linux-x86_64-20130219/sdk/platform-tools/dump $ for i in *apk; do printf "%-30s%s\n" $i "$(./aapt dump badging $i|grep label:|cut -d: -f2)"; done

You can test launch APKs on the hudl, by copying "aapt" executable from your SDK "platform-tools" directory to your current directory, and then make a shell script to do this:

 

1/ 

nano launch-apk.sh

PASTE THE CODE BELOW INTO THE SCRIPT (script assumes "adb" is in your PATH)
 

#!/bin/bash
pkg=$(./aapt dump badging $1|awk -F" " '/package/ {print $2}'|awk -F"'" '/name=/ {print $2}')
act=$(./aapt dump badging $1|awk -F" " '/launchable-activity/ {print $2}'|awk -F"'" '/name=/ {print $2}')
adb shell am start -n $pkg/$act

2/ Save and exit nano. 

 


3/ 

chmod +x launch-apk.sh

4/ Test launch APKs as shown (again, make sure "aapt" executable is in the dir you are running this from, and that "adb" executable is there too, OR in your "PATH":

./launch-apk.sh <nameOfApkToTest.apk>

Hi GlossyWhite,

I think you can get rid of "storelocator.apk" App too, as I think this is Tesco's Store Locator App

I would strongly advise not to delete applications from the system folder unless you don't want to receive any future OTA updates. Just disable the apps you don't want to use from the Apps option inside Settings then reboot your tablet. The apps will be prevented from launching, won't take up any RAM or other system resources and it still allows you to receive OTA updates as nothing has changed on the system.

For the "average" user with very little/no tech knowledge, I'd agree - leave things alone

However, if people don't know what they're doing, I'd be very surprised if they would pursue any of the hacks given on the forums. Even if they chose to, it's not such a disaster as people always make out that it is - this is a consumer computing device, not a life support machine, after all - what it THE absolute worst that could happen - a dead tab?

 

Learning to get yourself out of trouble by fixing errors and un-doing things you didn't mean to do, is the best means of technical education one can ask for. People are far too hand-held and mollycoddled nowadays - TRUE hackers aren't scared of taking things apart, voiding warranties, flashing bootloaders and soldering in mod resistors etc - that is how one learns to become proficient at such tasks - everything is dumbed-down by several layers of abstraction these days, all the way up to a pretty interface, so people become scared of experimenting.

Breaking things is good for your education - the BEST lessons are learnt hard.

I found a load of Tesco junk apps in 

/data/app

 ...too, so remounted as rw, created a folder there and moved them into it - seems to have sped things up somewhat.

Its a possibility we get it a few weeks/months after announcement and the AOSP release. We don't just have to rely on tesco for system updates, we rely on Archos/Rockchip too. So if both of them are willing to push the device up to 4.4 then we might just see KitKat on our Hudls.
