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:
