Apps Find the size occupied by String in Android

[Valak19]

I have an EditText in Android in which I enter text and store all those text in a Custom ListView. I want to calculate the memory occupied by the String in that EditText and thereby maintain a list of space occupied by each text.

Ex: S = "My favorite movie is Inception".

The length of S is 30. How much space will it occupy in the phone and how do I calculate it?

Each character is 2 bytes, so the memory occupied by your string is 60 bytes

I read few comments that memory occupied by String is not just calculated by no.of characters in the String. As the String is an object there are few more calculations to be done which I'm not sure of.

Well yes there is a certain overhead to storing all objects on the heap, in terms of object references. But using Strings is so common in a Java program, that the JVM optimises their storage by putting them in a String pool, a special area of memory allocated for String objects.
So if you create a new String object in your code, it may have new memory allocated to it, or it may simply refer to a String object already available in the pool. This is not under your control.
