process = Runtime.getRuntime().exec(su);
os = new DataOutputStream(process.getOutputStream());
os.writeBytes(exitn);
os.flush();
int exitValue = process.waitFor();
if (exitValue == 0)
{
return true;
} else
{
return false;
}
} catch (Exception e)
{
Log.d(*** DEBUG ***, Unexpected error - Here is what I know:
+ e.getMessage());
return false;
} finally
{
try

os.close();
}
process.destroy();
} catch (Exception e)

e.printStackTrace();
}
