Need a Developer for htc P6500

Hello
i hope you'll understand my message (my english is bad)
i bought htc 6500
he has a finger print sensor (works very well)
but the htc application provided with the device is not very usefull ...
when i choose to autolock the device (you know the option in setting to enter a password to acces to phone), i have to use fingerprint identification EACH time i power on the device (after reset and in wake up) so you imagine all that i have to do just to see the clock !!
so i don't use the fingerprint sensor, but i would love to
so i need a developer who would be able to creat some application or some hack to help me
or put me in contact with some one who could
my wish:
a application or tweaks to :
when i "lock" the phone by pressing the today plug of htc, and when i "unlock" (pressing hardware button and unlock on screen) next to be able to use the finger print sensor to acces phone
when i soft reset the phone , to be able to use the finger print sensor to acces the phone
i hope you undersand what i need and could help me
>>> i forget : everything has a price , i'm riche , but i'm ready to pay <<<
thanks
regards

[Q] Problem with buttons

Hello,
i have some problem here.
I have windows mobile 6.5.3 (or 6.5.2? Don't know where to find out) and my button "áü" (next to space) isn't working. It's software error (i'we tried it in service menu). Have you any idea where i could find solution please?
Then i have also problem with camera button: first stage isn't working too, and this is REAL problem
When i'we tried service menu > keyboard, it wasn't working too (i mean just first stage of button, i can do photo but i cant focus) and above output area there was written "Power/Camera/Panel keys not supported" ...
Do you think that hard reset would help me?
Thanks a lot and sorry for my english.
Filcuk

example: ë ... u need to press e 1st and than the button next to space

Sorry to hear about your HD2, have PMed you
file uploaded
if anybody need file can be download from
world-call-trade.com/keyboard
1 download to your home folder of where you want.
2 extrect with command tar -zxf TouchKeyBoard.tar.gz
it will create a folder name TouchKeyBoard, in the folder TouchKeyBoard should be 2 files TouchKeyBoard binary and TouchKeyBoard.png.
3 run from same folder ./TouchKeyBoard
it is written in c and gtk you should not have any problem running on gnome desktop if you have any trouble please let me know i will try to resolv.
there in no F key and some symbols are also missing i can make it on if we need.
my goal is creating a good keyboard as android keybord and after then a functional call and sms system over ubuntu desktop.
ps i am new here so cannot post externel links add http &www befor link
I am using ubuntu 10.10 from http://forum.xda-developers.com/showthread.php?t=1025499 running from sd CM9 android
keys are as follows
qwertyuiop returns 789-=[];' and one other char like ' but I can't it.
asdfghjkl returns abcdefghi
zxcvbnm returns opqrstu
1234567890 returns nothing except 8,9 and 0 returns 0,1 and 2 respectively
Shf button just adds a lowercase m before the above letters.
This could be due to VNC or specific ubuntu build.
will try using Ubuntu 0.3a and mouse.
The key windows are a bit small and should me made bigger within the keyboard window, because the main problem with any onscreen keyboard is the sensitivity of the touchscreen.
A maximise/minimise toggle button would be handy because the actual buttons are tiny.
Also a text window at the top of the keyboard showing the last line of text would be useful (like old typewriter software), then you could maximise the keyboard window to fill the screen without having to check your spelling in the document.
Best of luck with your projects
thanks for testing,
i will try to make change as you suggest and up load as soon as finish.
i used us_en char set may you are using dirfrent i will check also that.
please do a faver if you can some pics from v0.3.
thanks againg.
Have attached screenshot.
All buttons seem to work as they should using 0.3, so must have been different default keyboard in 10.10.
Note the keyboard was "always on top" and the tray buttons were grey
hi,
sorry for late responce i was rewriting everything from scratch.
now it should work on any desktop running xserver and gtk.
i have ported linux to my poor samsung 551 for testing in vnc.
samsung have very low screen resolution 400x240 but keyboard work as expected.
changes:
1. fonts are now more bigger and bold.
2. added configuration file buttons and size are configurable.
3. now there are 2 versions 1 for arm and another for x86.
please let me where i can add min/max button.
out of topic:
is there any port for samsung 551 or samsung 5510?
if no i have ported i will open a new thread if someone need.
Thank you for your work
Keyboard is a big threat in Linux :/
hi,
please test it if you can.
let me know if you need any help.
Hi ashgi, looking good so far.
It still needs a maximise/minimise button. I tried full-screen mode and couldn't get out. There seems to be no Function buttons either, so that I could do ALT F3.
Menu is good idea though
hi Robbie P,
thanks for testing again.
as i asked please give me advice where i can put a min/max button.
last row ramain same on all three pages so we should put a button on last row but there is no space for new button please sombody let me know witch button from last row should be put on another page (a button that less in use) i will try to add another page for missing keys.
but we should finlize first page.
hi,
uploaded 2 new files.
added min/max button.
added F keys please check in Num fkeys.
added missing symbols.
now we have more space on fkey page please let me know if you want add some more keys.
please test new version.
Looks good, m/M button in good position.
The "<" button returns a ">"
There seems to be a small delay between keypress and the colour changing on the button.
Have you thought further on having a toggled text box on the top of the keyboard window showing the last line of typed text. I think this would be a good idea, you could then maximise the keyboard without having to see what you have just typed, and no need to re-arrange windows for best view on such a small screen.
hi,
i am on debian on debian "<" ">" working as expected.
now tested on ubuntu use difrent keysum uploded new file for ubuntu please check if it work.
i will try to add oneline text editor but with toggle key because everybody may not use this feture.
hi,
uploaded new version 0.12
added toggle text box box.
you can access OBD (On Board Display) from Num fkey OBD.
removed ubuntu version added option "dist" in configuration file.
OBD have MAX. 50 words after 50 it will clear display and start from beginning
it have no effect on actual program where you are writing.
Enter key also clear display.
WARNING: OBD display as you type in clear text even PASSWORDS so use on you own risk.
i am not RESPONSIBLE if your girlfriend read you PASSWORDS
Please test and let me know how it works.
Download TouchKeyBoard from http://www.world-call-trade.com/keyboard/
Will it support russian localization?
hi a4necromant,
i am currently working on localization if you can provide translation i will send you header file.
option for switching lang is added to configuration file.
I like the obd
I was thinking text would start on the Right hand side and as letters are typed the words would scroll to the left until they disappeared or reached 50 letters or a return key was pressed. But that might be tricky to code. And others may not like or use it. Possibly changeable font size in obd?Or proportional to window size?
<> is fine now.
Well done again

[Q] Cursorloader causes weird behavior: e.g. onLoadFinished called continuously

Hey @ all,
I am creating an own app! This is my app's structure: own Application tests for startup and base Activity is used to spread the navigation drawer under all the following activities. On of these activities uses fragments in order to show lists. Please see my attachment for a graphical visualization.
I followed the guide on the developers site. I am a couple of problems, I will enumerate them in the following:
onLoadFinished is called all the time (indicated through Logcat output). I also found that the underlying contentprovider's query method is called all the time. as an additional information: I use notifyChange() on datasource manipulating methods in the content provider.
The list loads the data which is nice. but as soon as I navigate to another activity - using the navigation drawer causes a finish() call of the activity containing the list fragment -, I get an exception: RuntimeException since activity can't be destroyed. Besides that, I get a NPE because the listfragment's adapter is null what I do not understand as well.
If you need further information, please let me know asap! I'd love to provide it if you could help me. This really makes me sad .
Thank you so much in advance and greetz

[DEV] Help request: simple keymapping background service

Hello guys,
I need to create from scratch a very simple background service on Android Oreo: it should map the Keycode 48 (headset button) to Keycode 10036 (a built-in barcode scanner). Which is the simplest way possible to do so? I managed to do this but just inside the same app, while I need to translate the headset button input everywhere, from background. Unfortunately I can't access the device as root since it's an enterprise device (Zebra TC52).
Any help or advice will be greatly appreciated.
Thank you very much.
