Android / Android Porting : Trouble With Touchscreen

« on: February 05, 2008, 11:13:54 pm »

My touchscreen driver was incorrectly initialising the ABS_X [MIN/MAX], ABS_Y [MIN/MAX] values - these were supposed to be initialised according to the dimensions of the VGA panel (640x480) i am using. Also i had to calibrate the hardware reported X/Y values according to the 640 x 480 screen - i now pass these calibrated values (alongwith pressure value) to the input subsystem. My touch screen works fairly well now.

Thanks for the link AZ. I could update the dbase with proxy details, but username/password is still a problem.

Android / Cant Hear Sound On My Hardware

« on: February 01, 2008, 04:26:49 am »

Hello all,

i ran the video player (http://davanum.wordpress.com/2007/12/29/android-videomusic-player-sample-from-local-disk-as-well-as-remote-urls/) on Android ARM9 hardware device. While i can view MP4 and 3gP videos , i cant hear any sound. ALSA support is already added to my kernel image and my sound hardware driver is also ALSA compatible.

Any idea what is happening ? Is android using a different sound interface ?

Thanks
Joey

Android / Network Error - Error 32

Hello,

I followed these instructions to setup network for my Android based hardware -

------------------------------------------------------------------
Network is up.

A better way to bring network up.

--------------------------------------------------------------------

I get the android shell.  But when i search something on the browser i get a "Error 32 - www.google.com". Am i missing some settings ? I am able to ping my DNS server from the android shell though.

I am behind a internet proxy - how do i specify settings for the internet proxy server (ip,port,username,password) ?

Android / Android Porting : Trouble With Touchscreen

« on: January 28, 2008, 11:16:50 pm »

Hello all,

I am porting android to my ARM9 device and am having problems getting
the touchscreen to work. On my device  the touchpanel driver passes
absolute X/Y co-ordinate values to the kernel input subsystem. When i
touch the screen, more often than not , nothing happens. But on rare
occassions the main screen left/right scroll button might move or the
browser "google search" button might get pressed - but even for this i
have to give a real good thumb press, a firm tap is not enough.


I ran open source program evtest (which is an input event tester) and
it reported the co-ordinates of all my touches.


I then ran strace for the zygote process - i noticed that all of my
taps/touches/presses are read() by some thread which opens the /dev/
input/event1 device,  but no action is taken on the reported events.


I also modified the (touchpanel) hardware reported raw X/Y co-ordinate
values so that they correspond to the screen size (640x480 landscape)
and then passed these values to the kernel input subsytem, but there
was no change in behaviour.


I have read on some posts about "porting tslib" - what is this for ?
Is it required here ? Also some posts mention "normarlization of the
coordination" and "auto calibration using sysfs"  - what do they
mean ?


Any pointers/help would be appreciated


Regards
Joey
