Android: Go back to previous activity
...eep track of the activity stack. Whenever you start a new activity with an intent you can specify an intent flag like FLAG_ACTIVITY_REORDER_TO_FRONT or FLAG_ACTIVITY_PREVIOUS_IS_TOP. You can use this to shuffle between the activities in your application. Haven't used them much though. Have a look at...
Build fat static library (device + simulator) using Xcode and SDK 4+
...ary takes much more effort to setup, but much nicer long-term solution (it converts your library into a Framework).
Use this, then tweak it to add support for Archive builds - c.f. @Frederik's comment below on the changes he's using to make this work nicely with Archive mode.

Modulo operator with negative values [duplicate]
.... If the second operand of / or % is zero the behavior is
undefined. For integral operands the / operator yields the algebraic quotient with any fractional part discarded; if the quotient a/b is
representable in the type of the result, (a/b)*b + a%b is equal to a.
The rest is basic math:

What is the Java string pool and how is “s” different from new String(“s”)? [duplicate]

In computer science, string interning

of each distinct string value, which
must be immutable. Interning strings
makes some string processing tasks

Is there any performance reason to declare method parameters final in Java?
