I want to reboot my Android tablet by a button

Question

after searching for a while to solve the above problem, i found out, that my knowledge is terrible low. ^^

I found many describtions of 'how to reboot your device' but i dont really get them, or it is just for rooted devices (which mine is not). Now my exact Question: How can i achieve Systempermissions for my app, WITHOUT rooting it and without writing an own firmware? A´detailed explanation would be very welcome, because i have low knowledge of Java-, android-coding and my linux knowledge is down to 0, too. Please help.

A second question,answered in a single word: If i got the system key (wich i need for the permission, as far as i understood) does my app run on other devices, too, or does it belong to this key then?

You simply can't without root. – Stefan de Bruijn Mar 14 '13 at 13:14 — Stefan de Bruijn, Mar 14 '13 at 13:14

have a look at this http://stackoverflow.com/questions/9860399/shut-down-android-device-programmatically – itsrajesh4uguys Mar 14 '13 at 13:21
hmm.. thx, does the PM supports reboot or kinda time controlled start? – Eveli Mar 14 '13 at 13:29
yeah it supports .. seems cannot switch off or reboot without root. – itsrajesh4uguys Mar 14 '13 at 13:31
k thx... now i read that a root is nothing else but a superuser app, wich means it has to be possible to achieve these permissions, because the superuser apps have too. – Eveli Mar 14 '13 at 13:37

Root isn't just as simple as installing the super user app. You usually have to make sure that the bootloader is unlocked, flash a custom recovery and then flash a SU binary file. The steps for this vary depending on Device and the carrier – Boardy Mar 14 '13 at 13:48
@Boardy is correct. you need to connect your device with Pc and have to root it via Command Prompt – itsrajesh4uguys Mar 14 '13 at 13:53
so it is not possible to create a commercial app, running on not rooted devices with system permissions, right? – Eveli Mar 14 '13 at 14:20
what king of commercial apps you wanna create ? – itsrajesh4uguys Mar 14 '13 at 14:34
