int cannot be converted to java.lang.String

int i = 0;
String[] b = new String[]{releaseId, i});

causes an int cannot be converted to java.lang.String

From what I know java does implicit String conversion (in case of non-primitives a call to toString()) ?

So what is wrong here?

Is there something different about Java for Android?!

There are 2 "good" ways to convert an integer to a String. Integer.toString(i) or String.valueOf(i).

It is possible to do something like this String s = "" + i; but that is considered a bad smell.

Yes,

int cannot be converted to java.lang.String

Java doing implicit String conversion for Objects, not for primitive types.

You need to use Integer or String.valueOf(i).

That's true for objects. int is a primitive type not an object.

Use String.valueOf(i) to retrieve the String representation of i
