How to keep the application from dying when the user opens the camera?

Question

Android

Maybe someone has come across and knows how to solve the problem. The bottom line is this: every time I call the intent to open the camera and take a photo, the application dies and the answer no longer comes to it. Such a suspicion that the system decides to release the resources of minimized applications, and therefore kills it. The application is not loaded, one screen and a couple of data classes in a dozen fields.
Ps One of the crutch options that I found is to write my own screen to work with the camera. Then the application does not die.

Answer 1

1) You don't need it
2) Read about state saving
3) Not so crutch. Reliable, but more labor intensive.
