Thread: iOS App Crashes due to insufficient memory

    iOS App Crashes due to insufficient memory

    Hi there, I am currently developing a mobile app with realistic graphics (something similar to the zen garden app). I am pretty new to UE4 and have been trying to learn on mobile development.

    However, I am currently facing memory management problems. The application seems to be crashing after opening and stream 4-6 different levels depending on the size of the levels. Individually, the levels worked fine, but upon loading different levels one after another the app crashes.

    Below are a few things I have done to help relief in memory management:

    1. I have unload/unstream my levels before I open a new level
    2. I have removed all my UMG at the start of each new level
    3. I have garbage collect at the beginning of each new level

    The performance seemed to improve. But crashing issue still happened after. The diagnostics have shown to be a jetsam event which I read was a memory management issue.

    I am asking if there are any good practices and helpful methods for mobile app optimization?

    Thanks in advance.

    Maybe try to change a pool size and make some tweaks in DefaultDeviceProfile.ini?
