Android OS 2.2 Permissions: I have absolutely no idea why this simple piece of code doesn't work. What am I doing wrong?

Question

I\'m just playing around with some code. I create an Activity and simply do something like this:

long lo = currentTimeMillis();
System.out.println(lo);

lo *         


        

Answer 1

There is a SET_TIME_ZONE permission but there's no SET_TIME permission. Applications cannot programmatically change the system clock.

Update

SET_TIME is available since 2.2, but can only be granted to the system process or apps signed with the system signature.

Answer 2

insetad of System.out.println() use Log.v() or similar.

I think I found your error, please try it out: Remove </uses-permission> on both lines, that should work

Answer 3

using AlarmManager with SET_TIME permission to set system time seems to work :)
