[Q] running apps as root

For clarification...
An app has to request root permissions to run as root, you cannot just give it the permissions? Is there a setuid? The "/system" filesystem is ext3 on this phone. "ext3" supports setuid & setgid, are these supported by Android?
In other words, is there any way to give a non-root app root permissions?

have you "rooted" your bravo using super one click etc?
the su built for rooted android phones has a hook to the superuser.apk so that any app requesting root must be approved by the user. You can set the app to a whitelisted app so it always gets root permissions, so that is what i recommend. this is a much important security feature and i highly recommend you dont circumvent it. that being said, there is a su out there that doesnt require approval and just gives approval so you can find it on xda if you want it but really its not a good idea or recommended

I have a related question: How do pre-installed apps on unrooted phones get root permission? I would expect that there are some that do, although I cannot give any examples.

[Q] Help please need add Arabic Language

how to fix This { install blocked for security reason
for security your phone is set to block installation of applications not obtained from Android market
} and need add Arabic Language in my nook

this message show at when?????

You have to enable the option "Unknown sources: Allow installation of non-Market apps".
On most Android devices, this option appears in the Settings, but not on the stock Nook.
You can install a replacement Settings.apk (a bit tricky)
You can use various tools that will reset this option.
If you have root and adb then you can install sqlite3 for Windows on your desktop and do this:
Code:
adb pull /data/data/com.android.providers.settings/databases/settings.db settings.db
sqlite3 settings.db
update secure set value=1 where name='install_non_market_apps';
.q
adb push settings.db /data/data/com.android.providers.settings/databases/settings.db

I want to write a app just for move file to root how to do?

Hey guys i am brand new in android app develop I want to create a app just simply copy two file to root I want to know how could I start it?
I am computer science major so i know Java, C , C# and other language . But I think java is most easy way to do it ! Anyway I hope to get help to start my project ! Thanks:victory:

You have to use busybox
Like this
su (for superuser permissions)
busybox mv path path
You have to execute this commands from your app

[Q] Run shell script as root in android application

Hi,
I'm writing an android application which have to run a android shell script as root. But I don't know how to do that . Can anyone help me?
It's a very simple application with a button in the middle of the screen and if I press that button the script should be executed as root. :good:

Use
Process p = Runtime.getRuntime().exec("su");
p.getOutputStream().write("your command".getBytes());

You can use superuser libraries like libSuperuser by chainfire, or RootTools by stericsson to execute the script which can handle the output for you. You can assign the output to a String and then display it in a dialogbox.

You would need
say if your prcess is Process p
Scanner s = new Scanner(p.getInputStream)
while(s.hasNextLine){
//s.nextLine() will give the process output
}

Thank you so much for your reply. The links helped me so much! :good:
But i have one more question:
Can i also run multi line shell schripts from a file in the assets folder?
Example: i have a file: 'scripfile'. I put this one in the assets folder of the application. How can i run that file?

I can think of one way to do it. Like sak-venom1997 posted above, you can read the file one line at a time and save it to a String array or a list and pass the String array to the superuser library
PHP:
List<String> Shell.SH.run(List<String> commands)
or
List<String> Shell.SH.run(String[] commands)

Will it work for non rooted devices??

Will the codes be applicable for non rooted device? or it will run on all the devices..?
If it is for non rooted... then can you please suggest me how can I access shell.. or run shell commands without rooting the device.

If you take a look here
http://su.chainfire.eu/#how-call
you will notice this-
PHP:
List<String> Shell.SH.run(String command)
which I believe can be used for executing shell without root. Now I haven't tried it, so I am not sure, but it's worth a shot.

Question for making a simple app

I just need help at best way for me to build a simple app to request for root, then dd install a kernel
dd if=boot.img of=/dev/block/mmcblk0p14
and then give option to reboot.
Thanks for any advice

Just a tip, I'm assuming this app will work only for your device or similar partitioned devices. You could read the mounts file under proc using java and extract the Mount path instead of hard coding it. And executing shell commands can be done using JNI system() calls or from java it's Runtime.getRuntime().exec(ddcommandhere);

Well, let android studio create a project for you, you'll have an activity there run your code from there on another thread that's not the main ui thread.

perhaps you can just use a button in your MainActivity
And override the onClickListener
Then put that command(RunTime.getRunTime().exec().. in that method. Easy
