Default [Q] how to programmatically install/update in /system/app

Hi.
i have made a little application pushed in /system/app with adb qui connect to a server and sometime download apk for updating/installing apk on the device.

My application is a kind of "updater". I alreay can : install new apk
But i cant update an apk which is already installed in /system/app/
I dont know why, but the update is in /data/app/my-update-1.apk
The application use the new version but, if i reboot the device (a Tao3530 tsunami board), the apk in /data/app/ is deleted and the old /system/app/original.apk version used.

Why did i have this behavior ?
How could i update an /system/app apk ? (without using ADb of course )

If i need to use SU command (to push from download folder to /system/app, how could i root the board ?*

Thank you for any answer !

Default Just a piece of advice

If you are a developer go to android development if not i think you have to root your device and change permissions

I also suggest to google your device and use this words "" how to root -the name of your device- "" or in youtube///
