Acer Liquid - Development & Testing

[GoogleCodeExporter]

Let's add support for the Acer Liquid!

Looks like the device comes with a broadcom-wifi-chipset - so, the
iwconfig-method might work to bring the wifi-interface into ad-hoc mode.

Wifi kernel-module is located at:
/system/etc/wifi/dhd.ko

Parameters for insmod are:
firmware_path=/etc/wifi/BCM4325.bin nvram_path=/etc/wifi/nvram.txt

Interface-name of wifi:
eth0

I'm looking for testers who own a rooted acer liquid - netfilter (see FAQ) 
needs to
be enabled! Will be ready for a test-version today or tomorrow.

hi, harald.mue:

may i join you?
i'm a liquid user living in taiwan.
ive already rooted my phone.
i want to set my liquid works as a 3G wireless AP, but i didn't find the way to 
do 
that.
i used an app, aNetShare v2.30, before.
and i tried to fix some settings on my phone as the information i found on the 
internet, but i didn't find the file ,"tiwlan.ini".
is that because the different wireless chip used in liquid?

i installed the app you post above.
but, when i start it, it shows: "No Accesss Control -- your kernel does not 
have all 
necessary features for the control feature for this app." and shutdown soon.
do i need to change any setting?

i wish this information can do some for you (and me).
thank you for your tuning the tether to support liquid.

@mirox3m: Don't install kernel which were built for other devices!

Original comment by harald....@gmail.com on 24 Mar 2010 at 8:46

[GoogleCodeExporter]

For those people who have installed above mentioned test-version - please do:

1) Try to start tethering via GUI! Press the green icon and check "Show log" 
for errors.

2) If it fails connect to your device using adb and try to start it from 
command-line:

adb shell
cd /data/data/android.tether/bin
./tether start 1

This will generate more output for debug - please report what you got here.

Thanks.

Oh ... this looks like something (maybe you hint "deny" when the superuser-app 
popped
up) was blocking su-requests when installing the app. What you could do ...

adb shell
cd /data/data/android.tether/bin
chmod 0755 *

Then try to start:
./tether start 1

OR ... try to uninstall and reinstall.

Unfortunately, it does not ask for SU permission, it just FCs at start.

May be we should wait until official LiquidE ROM is released. This one is based 
on a

Ok, the problem is that the chmod-binary is not accessibly for the app. This is 
the
first time I see a rom which has this problem! You could try the following:

adb remount
adb shell
# cd /system/bin
# ln -s toolbox chmod
(this only works if toolbox exists ... if not, try with busybox "ln -s
/system/xbin/chmod chmod")

Then uninstall and reinstall the app.

Maybe a shared-library can't be loaded. Could you please check if the file ...

adb shell
# ls /data/data/android.tether/library/*
/data/data/android.tether/library/libNativeTask.so

exits?

If yes, start logcat so that it writes to a file ("adb logcat > tehter.log") 
and do
that reinstall binary/config-stuff.

To be honest I don't know why it fails loading that native-library. We don't 
use the
"normal strategy" for loading such libraries which makes it easier to include 
our app
in roms. I will do some rewrite this evening and upload a new test-app which
hopefully solves this issue.

Thanks for all your help.

harald.mue:

thanks for the new test-version.
i tried it, and got the same result as  mirox3m got at comment 13, 15 and 19.
the conf folder is not installed on phone with this version too.
while i start the test1.apk and the test2.apk, i got no popup menu to ask me to 
use 
the root permission or not.
and the app force closed soon.

i'm using the factory rom as acer_liquid_2.000.15_aap_fet.
its based on android 1.6.

i don't have a use cable now, so i do this steps by using terminal emulator on 
my 
liquid.

the file chmod in the system/bin folder points to the toolbox correctly,
and there is toolbox in the same folder.

i don't know how to use the loqcat, but the app still FC with this version.

Original comment by isahaya....@gmail.com on 25 Mar 2010 at 1:27

I tested the new version and there is no improvement. Same as  isahaya.tsubaki. 

Concerning version 1.6, I think it will be waste of time to develop an app for 
it. Acer 
LiquidE (same but with 2.1) will be officially available in April. Official 2.1 
update 
for old Liquids is promised for June.

It's really weird. Loading that native-library does work on nearly every other 
device
(all HTC device, Samsung Galaxy, Motorola Droid, NexusOne, ...) but not on the 
Liquid?!?

Anyways, I will rewrite the whole thing - and replace that native-lib with an 
pure
java implementation. This takes a day or two ...

Original comment by harald....@gmail.com on 25 Mar 2010 at 10:04

[GoogleCodeExporter]

To isahaya.tsubaki in Comment 33: 

To capture logcat: 

1. In Better Terminal Emulator Pro (or a terminal program), at the command 
prompt I
enter "su" to be superuser / root. 
2. Then type in: logcat > logcat.txt 
3. Press Home. 

The leaves the logcat writing to logcat.txt in the background. It will keep on
writing until you kill it via a task manager. The file can get very large if 
you forget. 

So, ideally, you want to do this immediately before starting the tether-wifi
app...and kill it as soon as possible after the experiment. Then just go get 
the text
file. By default it should be in /sdcard.

I'll join these experiments tomorrow (Friday here then). I can run either rooted
stock Android v1.6 or rooted LiquidE Eclair ROM. Or both. What's the priority? 

Also note that Acer provide a USB-tethering app with the Acer Liquid. But it is
Windows-only....so not much use to me as I mainly use linux.

Ok, good. Now what happens when starting via GUI? Press "menu" and select "Show 
log"
after you have started.

If you try to start via command-line it will generate more debug-output (it has 
to be
started via the gui first, because an config needs to be created).

So ... please do:

cd /data/data/android.tether/bin
./tether start 1

it doesn't FC for me, too.(but on the first time. then i started the terminal 
emulater, entering the order you typed above. FCing didn't happen again.)
but it still shows the message: "No Accesss Control -- your kernel does not 
have all 
necessary features for the control feature for this app.", and ask me to ignore 
or 
leave.
after i chose to ignore, it shows the message:"access control disabiled." and 
"binaries and confg file installed",but the message "could not install file -
data/data/android.tether/bin/dnsmasq." appears more often. 

i got the tether running log shows all done, except enabling NAT rules failed 
one 
time,and the other times 3 actions were done; those are loading dhd.ko module, 
enabling ip forwarding, tethering now running, and faied to start the others.

now i try to create logcat, and upload it later.
