I have an application. I started the email system application for example with this code:
new MessageArguments(MessageArguments.ARG_NEW, "email@example.com", "Email", "Body"));
In this case when i tried to close the background application (email system app) with the back key - nothing happens. After several times pressing to that button the whole my own application closes along with email system app. The question is why the back key pressing listener is not set to the email system app when is started by another application? It seems the back key pressing is listened by my own application despite of the fact that i use the Application class method requestBackground(), to put my app to the background.
