Hello,

I don't know if I can raise issue, but here an issue I have when I when to set 
a property as I can do with a "adb shell setprop my.key my_value"

What steps will reproduce the problem?
1. Use RootTools.debugMode = true;
2. RootTools.useRoot = true;
3. if (RootTools.isRootAvailable()) {
    Log.i(TAG, "SU is available !");
    try {
     List<String> output = RootTools.sendShell("setprop my.key start", 5);
    } catch (IOException e) {
        // something went wrong, deal with it here
        e.printStackTrace();
        }
} else {
    Log.e(TAG, "SU is not available !");
}

What is the expected output? What do you see instead?
When I check getprop with:
adb shell getprop | grep my
I should see
[my.key]: [start]

But on logcat I can see:
Shell command: setprop my.key start
Error: write failed: EPIPE (Broken pipe)

What version of the product are you using? On what operating system?
RootTools v1.7

Please provide any additional information below.
I there any specific permission to use ?
Can I use this library on a app installed "normally" adb install app.apk ?

I don't think this is an error with RootTools but with setprop. Does this same 
command work if executed from the shell on your phone?

With Android Terminal Emulator you mean ?
I am trying ...

SO the result:
a getprop works.

But for setprop i need su, but when I try su:

app_66@android:/ $ su
su: uid 10066 not allowed to su

:/

Strange, how a "su" binary cannot provide access to it ?

I'm not sure what is happening there, however I am pretty certain that what is 
happening is not related to the RootTools library :\

I have the same EPIPE broken issue on rooted android 4.0.3 devices with and 
without RootTools. So the issue shall not be related to RootTools. The problem 
is almost all the devices I tested broke the same way.

To test without RootTools, use this basic code:

Process su = Runtime.getRuntime().exec("/system/xbin/su"); // my is here

DataOutputStream os = new DataOutputStream(
su.getOutputStream());

// Getting the id of the current user to check if this is root
os.writeBytes("id\n"); // IOException EPIPE broken thrown there.
os.flush();

Off course, this is the correct path and name. I also tried many different su 
supposed to be OK but failed the same way.
