Android: Bundle identifier has not been setup.

Yes, that is like unity error messages defines format, but still it wont work.

The d*** Player settings button didnt work. (Edit->Project Settings->Player) worked for me. It is my first day with Unity and I am starting to get the same treacherous feeling I got with Eclipse. with little bugs here and there.

YES THANK YOU!

I can't get this to work, as "Identification" doesn't show up in one of my projects (it does on the other).

There's nothing in the docs that explains why it appears or disappears.

Any ideas?

That's simply not true. I've done this before but to make sure i just created an android build of my current project. I simply added "TestBuild" to the bundle identifier and it still builds without any problems even though my product name has a different value

The only requirement from Unity is that you enter something different from the default one. There is actually no true "rule" what the bundle identifier has to contain beside the allowed characters and that it has at least 3 parts. You can also use an identifier like:

 "this.is.my.unique.bundle.identifier"

Google just suggest to use reverse domain format to avoid conflicts with other peoples identifiers. It's actually better to have a longer identifier (with more than 3 parts). If you have a website you might want to start your identifier with that in reverse order.

So if you have a website called http://mydomain.com

you might want to use something like this:

 "com.mydomain.gamename"

or

 "com.mydomain.android.gamename.edition"

Personally i start all my bundleidentifiers either with

 de.B83.xxxxx

or

 de.B83.android.xxxxx

thank you. it's works.
