exec does not work, what to do?

Question

Android

Exec does not work at all, what is the reason?

final Runtime run = Runtime.getRuntime();
String[] cmd = new String[] {"su", "sh /sdcard/phar/phar.sh"}; 
run.exec(cmd).waitFor();

Answer 1

Well, what are you doing here to spam with your exec? I even sent you a code example in the last question .. and a good article with comments.
sdcard can be mounted with noexec so that all sorts of mommy kakirs are not naughty.
