i have a piece of code that works on Android 4.4.2 and below Android versions, but not in lollipop.
I knew that when lollipop came out, a lot off apps that needed ROOT permission stop working, but i don't know how they solved its problem.
This is the code:
System.out.println("Running tool");
Process p = Runtime.getRuntime().exec("su");
os = p.getOutputStream();
os.write((context.getFilesDir().getAbsolutePath() + "/tool " + context.getFilesDir().getAbsolutePath() + "\n").getBytes());
os.write("exit\n".getBytes());
p.waitFor();
All phones tested are ROOT.
In the line:
os.write((context.getFilesDir().getAbsolutePath() + "/tool " + context.getFilesDir().getAbsolutePath() + "\n").getBytes());
Throws the exception:

Anyone has encountered with this issue or know how to solve it?
Thanks to everyone.
First Of All Check Whether Your Phone Is Rooted Or Not..?
add roottools.jar file to your projects directory and use it in your code to successfully run superuser commands
Add the jar file from this link: https://code.google.com/p/roottools
https://github.com/Stericson/RootTools/releases
Importing roottools.jar into Android Studio
