Android Question where is app package name defined please

[Janusz Chmiel]

Dear specialists,Does somebody of us know, in which file is app package name defined? Which file do I have to edit in order to change default app package name?
Name is stored also in androidmanifest.xml, but B4A ide and compilation routines takes this default info from somewhere else.
Default package name is
package="b4a.example"

How to change it for new apps? In other case, I can not run more than one B4A compiled app at once.
Thank you very much for your answer.

In the 'Project' menu's 'Build Configurations' option (Ctl-B takes you there):

When I begin a new project I systematically do the two following steps:
1. Set the ApplicationLabel on top of the code in the Main module with the application name.
This is the name you see below the icon on the device.

2. Open the Build Configuration window in the Project menu.

And set the Package name.

Even, when I download any project from the forum I check these two properties to avoid B4AExample.
