execute reboot command from application

Hi
I'm trying to get a reboot application working.
It should get root through "su" and then execute "reboot".
It does, but nothing happens (su request shows up)
I used several ways to execute the commands.
The ShellInterface classs from MarketEnabler and this snippet http://www.anddev.org/root_access_snippet-t8384.html
"su" then "reboot" -> nothing
"su -c reboot" -> nothing...
Always the same, it looks like it worked but the device is still up
adb logcat says nothing about.
What's wrong?
I'm running it directly on HTC Hero rooted of course

I've had this issue on several ROMs. I guess some just don't support the command.. *shrug*

It should work...
The reboot binary is present

Hello out there. Looks like you just have a tiny error with your code.
"su -c reboot" needs to look like so: "su -c 'reboot'" -- the actual command to be executed has to be in quotes.

That sould work without the quotes
Still can't find the problem.
I chowned and chmodded the reboot binary like the su binary still no change

how does adbd do it without root permission?
the adb daemon on the device has to be able to do it to be able to respond to 'adb reboot' on a non-rooted phone. Anybody know how it is able to perform the reboot?

Try this, i can confirm it works fine
Code:
try {
Process process = Runtime.getRuntime().exec("su");
DataOutputStream os = new DataOutputStream(process.getOutputStream());
{
os.writeBytes("reboot\n");
os.flush();
process.waitFor();
}
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}

This requires a rooted phone. How does adbd reboot on a non rooted phone?

It works on some, doesn't work on others. Seems to be something with how the phone is rooted, or how permissions are set, not exactly sure. Either way, just because it works for you doesn't mean it will work for everyone, however the code up there is probably a very good example for an implementation.
Some apps like ROM Manager have their reboot written using the NDK, so that may be a reason why they can reboot whereas other apps which try to reboot fail.

[Q] Reboot, Su, App

Hi, i am trying to run adb and su commands in onclicklistener of my button of android app and here is my code
Code:
btnCheckSu.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Process p; String[] st = new String[3];
try {
st[0]="/system/bin/su";
st[1]="-c";
st[2]="reboot";
p = Runtime.getRuntime().exec(st);
Toast.makeText(SUCheck.this, "Rebooting...", Toast.LENGTH_SHORT).show();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
I do get the prompt for su but then phone does not reboot...any help please
thanks

Well im not sure about the su commands but the reboot intent is restricted to processes signed with the same key as the platform you are using (essentially the key used to sign the rom you are using)
It could be the same with using su to reboot. Not sure though
--------
I tried it on the terminal emulator and it worked after entering the command twice for some reason
From something awesome

Try your commands via adb root shell first. If they work then u know the condemns are good and can try something else. All so without capturing process output there it's no way to know what's going on.

Why not use the standard android api?
Code:
PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
pm.reboot("");
You'll need the REBOOT permission though.

Because as i said before the reboot permission is only valid on system apps signed with the platform key

You're right, sorry.
Try this instead, it worked fine for me.
Code:
Runtime.getRuntime().exec("su -c /system/bin/reboot");

i guys
thanks for the above replies...
but none of the above suggestion has worked for me...any other clues please
thanks

.../me repeats himself...
CAPTURE UR OUTPUT, without it we cant know what is going wrong.
Try your commands via adb shell first, if they work there they will also work via your phone.

yup, great.... adb working through my pc shell
capturing output...i have to work that out how...cheers

from your process create datastreams for your process.getInputStream() and process.getErrorStream(). After execution dump streams to file/logcat/w/e.

You can restart the service using adb's ActivityManager (am) using the following command
Code:
am startservice -n com.android.systemui/.SystemUIService
To execute the same command from your app, make use of Runtime.
Code:
final Runtime runtime = Runtime.getRuntime();
try {
runtime.exec("su -c am startservice -n com.android.systemui/.SystemUIService");
}
catch (IOException e) {
e.printStackTrace();
}

Try below code. Cant test it ATM
Code:
runtime.exec("su -c mount -o remount,rw /system");
File myfile = new File(Environment.getExternalStorageDirectory() + File.separator + "test.txt");
myfile.createNewFile();
String data ="My test data";
//write the data in file
if(myfile.exists())
{
try {
OutputStream os = new FileOutputStream(myfile);
os.write(data);
os.close();
Toast.makeText(this, "File created successfully", Toast.LENGTH_SHORT).show();
}catch (IOException e)
{e.printStackTrace();}
runtime.exec("su -c" + Environment.getExternalStorageDirectory() + File.separator + "test.txt" + "/system/");
}
//deleting the temp file
file.delete();
Toast.makeText(this, "File copied and deleted from temp dir", Toast.LENGTH_SHORT).show();
To start it again, put that in a function and call that function whenever you want to execute it.
Example of function:
Code:
public void myfunc(){
//Your code to be executed more than once
}
And in some other function, say onCreate(), call
Code:
myfunc();

That's gonna be different. You have to put the file in asserts and extract the file to system more or less the same why like creating the file and copying it to system.
And for systemUI restart, you can try this:
Code:
Process p;
p = Runtime.getRuntime().exec("sh");
DataOutputStream os = new DataOutputStream(p.getOutputStream());
os.writeBytes("am startservice -n com.android.systemui/.SystemUIService\n");
Its pretty much the same but with a little different approach.

Let me try a working code today. Sorry for posting non working codes as I can not home yestersay to test 'em. BTW, you can also look for it in opensource xposed framework modules because many xposed modules needs to do a restart of systemui.
Sent from my GT-N7000 using xda app-developers app

Ok...a friend of mine who has more experience than me said, the code is correct but is not working with recent builds. Searching doesnt give me any convincing results. So thought to provide you code to hot reboot. This code is tested and works well.
Code:
try {
Process proc = Runtime.getRuntime()
.exec(new String[]{ "su", "-c", "setprop ctl.restart zygote"});
proc.waitFor();
} catch (Exception e) {
e.printStackTrace();
}
This will cause the zygote to restart which will in turn makes the whole system core reboot. Works well on my Galaxy note running 4.1.2. This the easiest method I can think although I could restart systemui by killing SystemUI process by "kill pid" But it would be lots of work to find systemui pid because it is not static

That's not a whole system reboot. It only restarts core system services. So its already fast than normal reboot.
Anyway, NVM, found a better working method which is working on my Galaxy Note N7000 running 4.1.2
Code:
try {
Process proc = Runtime.getRuntime()
.exec("su -c pkill com.android.systemui ");
proc.waitFor();
} catch (Exception ex) {
ex.printStackTrace();
}

[Q] Help with Chainfire's libsuperuser./Progressbar for asyncactivity

Hello there,
I know this is a noob question but I am unable to implement libsuperuser by chainfire for my app, I can't understand the Asyncactivity he creates in his example project. I have tried that way for a simple Root Checker app, but i am unable to do it, beacuse my app doesn't ask for superuser permissions
So, could anyone please point me to any sample program using his libs, which is simple enough for a beginner to understand .
Thanks in Advance.

Why don't you try roottools library? It's really simple, and intuitive. Lots of documentations also available!
Here is a link for you : http://code.google.com/p/roottools/
For su request on start, you must have:
Code:
<uses-permission android:name="android.permission.ACCESS_SUPERUSER"/>
in your manifest.
To check for su :
Code:
if(RootTools.isRootAvailable())
Log.e("YourTag","We have root!");
else Log.e("YourTag","No root access :( !");

Thanks for your reply. I tried adding the permission but it didn't work with libsuperuser. It must be something I wrote in the program.
I am now trying with roottools -
so if I have to copy a file from data/app to sdcard, how will I pass the shell command using RootTools ?

Thanks for your replies gentlemen. I finally settled for CMDProcessor and succeeded in making my command to work.
Now the command takes a long time to finish as it involves copying quite a few files and as it froze the main UI thread I used ASyncTask to take the heavy work to background thread.
Now I can't find a way to show a progress bar for the activities going on in the background thread. Can you please shed some light on how I could set some kind of progress update ... Thanks In Advance.
Edit : Should I use something other than ASyncActivity as the file copy opeartion takes several minutes and android developer website suggests to use executor or futuretask for tasks that require too long to complete

If it really takes that much time, I would use a remote service (a remote service runs in another process).
Using a remote service, closing the app using the recent apps menu won't stop that. The same applies for UI crashes. The copy operation won't stop if the UI crashes for whatever reason. You won't have to worry about orientation changes as well.

Thanks for your reply again, I was trying to find a way to visualize the progress with a progress bar or something. Although I could not make a progress bar to work I was able to implement a spinner . . . Although a progressbar still would have been better, but for now, it serves the purpose of creating a sense of the activity happening in the background .
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I will try to understand and implement the remote service that you linked, lets hope it isn't too much work .
Edit : The advantages you stated for remote service are all here too, even when I killed tha app from recents menu, the file copying operation still went on in the background .
Edit 2 : Orientation change only removes the spinner dialog, but the file copy operation proceeds until it's complete. The only thing that seems to stop the operation is when i uninstall the app from my device, while its still being executed. So I would say this baby is rock solid, just an addition of a progress bar would serve it well. :victory:

Well, you could try to do it like this:
Copy the files one by one or copy 5 at once. And afterwards set the progress to a higher value. That would, however, be more time consuming as the IPC (InterProcessCommunication) takes much time.
You could also do the copying using a script and "echo" some output after every 5 copied files. Then you would need to constantly listen for output and if you receive any, increase the progress value.
I would go with the spinner for performance though.

Copy the files one by one or copy 5 at once. And afterwards set the progress to a higher value. That would, however, be more time consuming as the IPC (InterProcessCommunication) takes much time.
You could also do the copying using a script and "echo" some output after every 5 copied files. Then you would need to constantly listen for output and if you receive any, increase the progress value.
I would go with the spinner for performance though.

Hmmm, interesting idea. I am using a shell command , which one would be better, guess I could echo some output to a dialog box.
On the contrary it would slow down the performance of app, so like you said spinner would be better for performance.
Still I would try to make some sort of progress bar work, please suggest which method should i use. I am using a shell command
"cp -r /data/app/ /sdcard/backup/apps" , to copy a whole directory to sdcard .

This one would be slower but would give you an output after every copied file:
Code:
find /data/app -exec cp {} /sdcard/backup/apps \; -exec echo copy \;
It doesn't work properly with subdirectories though. However, that won't be important for you as /data/app doesn't contain subdirectories.

Use this to get the total number of files in /data/app/:
Code:
ls /data/app/ | wc -l
---------- Post added at 11:09 PM ---------- Previous post was at 11:06 PM ----------
Using
Code:
ls -f /data/app | wc -l
will make it even faster because the list (whose lines are counted) won't be sorted.

I was using this to get the no of files in the directory
find /data/app -type f -print| wc -l
But i couldn't figure out how to monitor the no of files copied to the sdcard to make a progressbar out of it.
And for this find /data/app -exec cp {} /sdcard/backup/apps \; -exec echo copy \ i assume the output will have to be shown in a dialog box.
On another note, thanks a lot for helping a nobody like me out. I am trying to learn app development and people like you are making it easier for me, means a lot to me. Keep up your awesome work and keep spreading your knowledge. :good:

The new and faster version I posted above (ls -f /data/app | wc -l) should be the best (i.e. fastest) way to get the number of files.
Then you would need to constantly check the output of the java.lang.Process which runs your command. Change the progress value of the ProgressBar after every line of output.
I'll look into that tomorrow if you post a link to your CMDProcessor version in the meantime. Got to get some sleep now.
Thank you very much for the compliments... and welcome.

My idea would be to add another run method to the SH class:
Code:
public CommandResult runWaitForWithProgress(final String s) {
s += "; echo This is the end of the command";
if (DEBUG)
Log.d(TAG, "runWaitFor( " + s + " )");
final Process process = run(s);
Integer exit_value = null;
String stdout = null;
String stderr = null;
if (process != null) {
try {
final DataInputStream dis = new DataInputStream(process.getInputStream());
while (true) {
if (dis.available() > 0) {
if (dis.readLine().equals("This is the end of the command")) {
break;
} else {
//TODO: Increase progress here
}
}
try {
Thread.sleep(200);
} catch (Exception e) {
e.printStackTrace();
}
}
exit_value = process.waitFor();
stdout = getStreamLines(process.getInputStream());
stderr = getStreamLines(process.getErrorStream());
} catch (final InterruptedException e) {
Log.e(TAG, "runWaitFor " + e.toString());
} catch (final NullPointerException e) {
Log.e(TAG, "runWaitFor " + e.toString());
}
}
return new CommandResult(exit_value, stdout, stderr);
}
I've written this in a text editor and haven't tested it. So no guarantee that it will work. You'll probably have to fix some errors. But it should explain my idea.

In Java :silly:
I m trying to write the output of the command to a text file in sdcard
Code:
cmd.su.runWaitFor("ls /data/app/ | wc -l > /sdcard/bck.txt");
My aim is to use it to store the no of apps from the text file to a variable , and then use it for the progressbar .
Although It writes a text file with the no of apps as its content, i am unable to assign it to a variable in java
Code:
FileInputStream is = null;
BufferedInputStream bis = null;
try {
is = new FileInputStream(new File("sdcard/backovery/bck.txt"));
bis = new BufferedInputStream(is);
nFiles = bis.read();
}catch (IOException e) {
e.printStackTrace();
tv.setText(""+nFiles);
It works but shows the value for nFiles in textview as 0 .
But it will be less messy if I could just store the shell command's output to a variable instead of storing it on a text file .

NTFS on your android with full read write support

How to install this:
1. put copymodulecrc to the /data/local/tmp folder and chmod them to 755
(adb shell chmod 755 /data/local/tmp/copymodulecrc)
2. put ntfs-3g and ntfsmount to the folder /system/bin and chmod them to 755
(adb shell chmod 755 /system/bin/ntfs-3g)
(adb shell chmod 755 /system/bin/ntfsmount)
3. put sdcardfs.ko to the folder /system/lib/modules and chmod them to 644
(adb shell chmod 644 /system/lib/modules/sdcardfs.ko)
What is next? Next:
1. in order to get it working, sdcardfs.ko must be patched to match your kernel version since every kernel modules is paired with kernel by version string, so if version string not match module version it will not work! So you must patch sdcardfs.ko module using tool called copymodulecrc! Copymodulecrc will extract version string from any module of the your stockrom kernel modules and copy them directly to the sdcardfs.ko (patch them). First of all you need to look into your /system/lib/modules folder and use any .ko file NAME for referencie in next commands:
Code:
adb shell /data/local/tmp/copymodulecrc /system/lib/modules/PUT_NAME_OF_THE_KO_YOU_FOUND_IN_STOCK_ROM_KERNEL_MODULES /system/lib/modules/sdcardfs.ko
So replace PUT_NAME_OF_THE_KO_YOU_FOUND_IN_STOCK_ROM_KERNEL_MODULES with the name of the any module you found in modules folder! Done.
2. if you completed step 1 without errors you are ready for this step. You need to locate script called install-recovery.sh (on most devices it is in folder /system/etc) and add next lines:
Code:
insmod /system/lib/modules/sdcardfs.ko
Done. On every next reboot sdcardfs kernel module will be automatically included in your kernel.
3. if you get error in patching sdcardfs.ko whole thing will not work! So these step is important! You can verify success by command: (su -c "insmod /system/lib/modules/sdcardfs.ko") , if you see error than sdcardfs is not working, if you see nothing than it is working
Since you completed these 3 things, you are ready to use NTFS volumes on your device! To understand these things:
1. first of all, you can not mount ntfs volume regulary trought settings menu since android not support ntfs by default! You must mount/umount your ntfs volume manually (you can use for example android terminal emulator when you need to mount/umount ntfs). You will not see any details about ntfs volume in settings menu since android not support ntfs by default, you can see details in most file managers only.
How to mount and unmount:
1. to mount (first connect your usb ntfs volume to your device usb port) :
Code:
su -c "ntfsmount mount"
Done! Your ntfs volume by these command is mounted and you are ready to read/write them using your faworite file manager
2. To umount (do in mind - every time before you going to remove ntfs volume from your device you must unmount it!):
Code:
su -c "ntfsmount umount"
Done! You are ready to remove ntfs volume from your usb port.
NTFS on sdcard? Yes but you need to modify a bit ntfsnount script! Don't ask me how ypu can modify them, do it byself!
Since somebody complain here about gpl licence, I am not ready ready to share sdcardfs source code with you since it is not gpl licenced, instead it is apache 2.0 licenced by Samsung guys @ 2013 and I no need to share it with you since you wanted to see them forced! I not like when somebody forcing me for something! Find it, patch them, make module of them byself
ntfs-3g is not compiled by me, it is used from here -> http://forum.xda-developers.com/showthread.php?t=1724078
ntfsmount script is created by me.
Copymodulecrc I do not know where I found them but here is source code:

And finaly, files you need to install is in attachment, enjoy!

Will try late-night. Just asking, will it work on Galaxy S3-GTi9300?

Just need some clarification, when you say NTFS support, do you mean read and write or just read-only?

Not going to explain in details, here is my tool which will add ntfs support to your android, run them and folow instructions! If you unable to patch sdcardfs.ko kernel module (giving you error when you doing insmod) than the whole things will not work on your device Curntly tested device is Xperia Z1 Compact on android version 14.4.A.0.108! Important thing is having sdcardfs installable, the rest is easy.
In order to have sdcardfs module insmoded on every reboot, you need to add one line into /system/etc/install-recovery.sh :
The rest of the tutorial you can see under application. Enjoy if you find this usefull!

/system/etc/install-recovery.sh :-
- install-recovery.sh file is not available at /system/etc/.
- Is it possible to create the file and then we can insert the line?
Am using AOSP - Carbon ROM on Xperia Z..
Thank you!!

Thanks a lot! :victory:
Looking forward for what all can I do with it.

Wow this will be amazing, cant wait to try...

Just a heads up..
On Xperia Z2 tablet with 4.4.2, connected to 1tb NTFS drive.
After modding the ko and setting all permissions, rebooting, will only "half-mount" the drive. It sees it, recognizes it, but claims drive is empty (wants to format it).
Status bar displays "Empty USB Storage"
In settings, when selecting Mount USB Storage, it briefly acts like it will mount. for a split second.
Any files I can get that can possibly help?
UPDATE: After running the mount commands via terminal, now it seems to mount it via ES File explorer. Although it sometimes still gives me the message in statusbar.
But seems to be working well.

Seeing as this patches a kernel module will it work on rooted phones with a locked bootloader?

My Z2 Tablet has a locked bootloader. So yes, it should. There's nothing going on that warrants an unlocked bootloader. Just the addition of some files and permission changes, which are normal with a rooted device.

Also note, that in the Settings\Storage, it will not show up as being "mounted". At least not in my case. However, ES File Explorer has no issue with it, and shows as a USB 1052 drive under the "Local" menu. Navigation seems normal within the drive.
I get the "USB Drive Empty or Unsupported" message in the status bar, for a few seconds, but the ES FE displays the drive contents, and the message goes away after it reads drive contents. Note that it may assign a different drive identifier each time you use it.
In testing I have found apps from the market;
StickMount does not work at all on my Stock OS.
Paragon NTFS mount works, but it runs as a system process using memory and probably battery.
This mod seems to work, for the most part, as long as you use ES File Explorer.

OP - you must provide the source for any modified code covered by the GPL that you are distributing - that includes the sdcardfs kernel module, and the ntfs-3g binary. Packing them in an encrypted Windows executable does not help.

No he doesn't. Only the zimage (kernel) is covered under GPL.
UPDATE: Just to clarify, the matter "Has" been brought to the Developers Committee to address any possible GPL violations. The DC is more informed on GPL.

What? No. The ntfs-3g project is licensed under the GPL. And so is the sdcardfs driver. You can't generate binaries from GPL code and distribute them without providing the source.

First off, permissions must be set to 755 (rwx-rx-rx) if I'm not mistaken. Root Explorer converts it to the numerical format when you change permissions.
Next, use a terminal program (available from the play store) Make sure you run it as SU. (type SU + Enter, you will get the # sign) Then type in the commands and paths as indicated. (I copied and pasted my paths)
