Bypassing Root Detection

I'm trying to find a way to bypass an application that has root a root detection method that looks for superuser.apk, then tries to run "su -c ls" and looks for an exception. Any ideas how to get past this. It gets superuser.apk by doing something similar to this (from what I can tell):
List localList = getPackageManager().getInstalledApplications(0);
int rooted = 0;
for(int i = 0; i < localList.size(); i++)
{
if (((ApplicationInfo)localList.get(i)).publicSourceDir.toLowerCase().contains("superuser.apk"))
{
rooted = 1;
}
}
For the "su -c ls" I think it does something like this:
try
{
Runtime.getRuntime().exec("su -c ls");
rooted = 1;
}
catch (Exception localException)
{
rooted = 0;
}
So, it looks like I basically need to change the name of superuser.apk or block the package manager from seeing it. I've been trying to find where it's getting superuser.apk so I can change the name but I can't find where to do that. For the "su -c ls" I'm not sure how to get by that except for patching su so it won't allow that particular command, any other ideas?

Since both superuser and su are open-source, it could be as simple as recompiling superuser under a different name, and su patched, as you point out.

By that recipe just rename su to something random and create a gscript that runs the newsu and creates an su and superuser.apk when you need them, delete them when you don't.

First moved .
Second as stated above u would need your to make ur own special su binary and superuser apk.
Create you program as needed, have it use su to install your own su binary of a different name then use ur orginal apk as teh new superuser.apk. Then finally unstill original su/superuser.apk.
This is not a great method as you will loose root access for all other applications. But afaik you not going to be able to block the package manager from seeing superuser.apk.

[Q][DEV] Writing to /data partition without root?

Hello I am desperately trying to run a shell script from my java app.
I tried to use http://developer.android.com/reference/java/lang/Runtime.html#exec%28java.lang.String%29 Runtime Exec to run it and it works except nothing really happens and the script is not executed.
My command was "/system/bin/sh /data/local/test.sh", of course properly chmodded. I tried running the test.sh directly, even tried opening a SH instance and pushing commands to the console via output buffer - nothing works.
When I try to run SU for example using any of these methods, I get prompted for superuser access, so it does work, just doesn't work like I want.
Anybody has any idea what's wrong? Or alternative way to run a script post-boot? (init.d executes too early in the startup process for my needs)

Are you capturing the error stream, or just the output stream?

This is everything I tried:
Code:
String[] str = { "/system/bin/sh", "/data/local/test.sh" };
Process p = Runtime.getRuntime().exec(str);
p.waitFor();
Code:
Process p2 = Runtime.getRuntime().exec("/system/bin/sh /data/local/test.sh");
p2.waitFor();
Code:
Runtime runtime = Runtime.getRuntime();
Process p = runtime.exec("/system/bin/sh");
OutputStream os = p.getOutputStream();
String str = "/data/local/test.sh";
byte[] cmds = str.getBytes();
os.write(cmds);
os.flush();
os.close();
calling just "/system/bin/sh" or "su" works - it actually waits indefinitely in each approach but once I try to execute a script it won't budge. I also attempted to run other parametrized commands like "setprop persist.sys.use_dithering 0" and it also failed. I'll try to intercept the error stream, good point.

You need the "-c" option to execute a script:
Sorry I missed that in your first post.
Code:
String[] str = { "/system/bin/sh", [COLOR="Red"]"-c",[/COLOR] "/data/local/test.sh" };
Process p = Runtime.getRuntime().exec(str);
p.waitFor();

nope, this is what I have
Code:
String[] str = { "/system/bin/sh", "-c", "/data/local/test.sh" };
Process p = Runtime.getRuntime().exec(str);
p.waitFor();
still no effect, the /data/local/test.sh is 0777 and only contains
Code:
echo "success" > /data/local/testresult.txt
The same command works from ADB even without the -c switch but with the exec command nothing happens.

finally progress
Update: according to the error output the file gets executed BUT it doesn't have permission to write in /data/local/ same problem if I try to write to this dir with java API.
My script needs to write there so I have only one question - is there a permission that would allow me to execute a script with access right to /data partition without root?
I want to modify the userdata partition after first boot of the ROM but I can't ask the user for root, I want to execute my tweaks and reboot the device before even the android login wizard appears so asking for root that has a prompt with timeout is not an option.
I know of an alternative way to do it but it's even more hacky than this and I would like to avoid someone vomiting over my code

Does it need to be /data/local? /data/local/tmp is world-writable on most devices.

In the end it needs to be /data/data/ actually, I want to mess with default settings of apps, system settings database for example... does that mean I need root or game over? Is there no permission for app to get access to the userdata partition?

As far as I know, the Dalvik system was set up that way on purpose to prevent errant apps from causing any problems elsewhere, and to maintain decent security (look how out of control Windows has become), so to answer your question, Yes, I believe you will need root.

No, you can't write to /data/data without root (as that would be a major security risk).

Ok thanks guys I will try my dirty workaround

Terminal command for reboot in recovery

The command for rebooting is
Code:
reboot
Use that to reboot into recovery:
Code:
reboot recovery
For bootloader you need to use adb:
Code:
adb reboot-bootloader

Runtime.getRuntime().exec(new String[]{"su","-c","reboot bootloader"});

He wants to use RootTools.
For that use:
Code:
Command command = new Command(0, "reboot bootloader") {
[user=439709]@override[/user]
public void output(int id, String line) {
//TODO: Do something with the output here
}
};
RootTools.getShell(true).add(command).waitForFinish();
EDIT: @override: The first letter needs to be upper case (Doesn't let me as it thinks of it as a mentioning function.)

First you need to be a root user.
Type "su" as the first command.
If you use RootTools you can execute commands as root without having to type "su" the way I gave you above.
Second adb commands must be launched from your computer.

If I type "su", then press enter and then "reboot recovery", everything works fine.
Look at this for rebooting into bootloader: http://www.androidcentral.com/android-201-10-basic-terminal-commands-you-should-know
EDIT: You can see whether you typed "su" by looking at the last character of one line. If it is a # instead of a $, you typed "su".

Then it is because of the implementation of the reboot command of your ROM. On my Samsung Galaxy Ace with AOKP it is working fine.
Maybe you could compile your own busybox and include the reboot command. Then copy it into the data directory of your app and run the commands by typing their full path like this:
Code:
/data/data/com.example.app/files/busybox reboot recovery

Mmm, if i add this myself-compiled busybox version to my app, this will work with all devices?
Because as you can read in the first post, the command should be written in the app I'm working on.
Or there is a universal another command or another way to do it?

I really thought that you could use the "reboot recovery" on every device.
However, this is one of the best examples for different implementations on different devices. For example on some phones the "ls" command is linked to "ls -l" (Source). That is why busybox is always the better way. It is working the same on all devices and ROMs.
You need to compile it yourself because the one which is installed by this app does not include the reboot command.
I think that there is no other way as the "universal" did not work on your device. Maybe anotherone has a better idea, but I do not think so.

Thanks man, I've tried
Code:
su
reboot recovery
and
Code:
su
reboot bootloader
in my Galaxy Nexus, it works.
I will develop and test the app on Nexus, pure Google software

You could grab the reboot binary (I attached mine from the nexus 7), put it in /system/xbin then do this in terminal :
Code:
su
chmod 775 /system/xbin/reboot
After which, reboot/reboot-recovery/reboot-bootloader should work.
If this works, you can include the binary in the assets folder of your app, then copy it to /system/xbin and chmod it in your code.
Code:
File sdCard = Environment.getExternalStorageDirectory().toString();
File update = new File( sdCard + "reboot");
if (update.exists()) {
System.out.println("reboot binary already exists on sdcard");
} else {
try {
update.createNewFile();
System.out.println("File created successfully");
InputStream is = getAssets().open("reboot");
FileOutputStream fos = new FileOutputStream(update);
byte[] buffer = new byte[1024];
int length = 0;
while ((length = is.read(buffer)) > 0) {
fos.write(buffer, 0, length);
}
System.out.println("reboot binary successfully moved to sdcard");
// Close the streams
fos.flush();
fos.close();
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
Process process = null;
process = Runtime.getRuntime().exec("su");
DataOutputStream os = new DataOutputStream(
process.getOutputStream());
os.writeBytes("busybox mount -o remount,rw /system"+"\n");
os.writeBytes("cp -f " + sdCard + "/reboot /system/xbin/reboot" + "\n");
os.writeBytes("chmod 775 /system/xbin/reboot" + "\n");
os.writeBytes("rm -f " + sdCard + "/reboot " + "\n");
os.writeBytes("busybox mount -o remount,ro /system"+"\n");
os.writeBytes("exit\n");
os.flush();
process.waitFor();

process = Runtime.getRuntime().exec("su");
DataOutputStream os = new DataOutputStream(
process.getOutputStream());
os.writeBytes("reboot recovery"+"\n");
os.writeBytes("exit\n");

Really great idea. :good: Respect!
Just one thing I would do another way: I would copy the reboot binary to the data folder of the app so that the system is not modyfied.
If the default reboot binary has some additional functions which the system needs, there could go something wrong.

2-How to replace a file from assets to system(switch between 7 files depend on user choose)...
3-How to set permission of file to rw- r— r—?

Sorry to ask this, but have you learnt java basics first? Because I feel, you lack basis - Its not humiliation but this something you need on first hand to be a good developer.
1. I have already answered how to mount system as RW:

runtime.exec("su -c mount -o remount,rw /system");
2. The first link you gave has answer for setting permission in 1st answer.
3. To extract assert, refer this answer:
Hint: put up a dialog asking which file to extract and then adopt the above answer to extract it to sdcard first them copy it to system using runtime and cp command.

This simply means the framework file you're trying to replace is crucial to the system, and thus the device will reboot if it is deleted.

[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 ?

Keep in mind that commands are as super-user, so no need to "su -c" / "su"..

How do I get past this error -
The method waitForFinish() is undefined for the type Command
Sorry for so many stupid questions, i am trying to learn

I didn't close try{}, sorry! Put a "}" at the end of my code and it should work!
If you have any questions, feel free to pm me.
Edit 3: I have corrected my post. Copy paste the code above and should work now.

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.

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.
---------- Post added at 11:06 PM ---------- Previous post was at 10:58 PM ----------
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.

Is there a way to assign the output given by

ls /data/app/ | wc -l
to a variable ???

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 .
