Unity Android game crashes when reopened from the home screen.

Question

Hello,

Our game is ready or not really ready for Android.

When I play the game and I hit the home button, I get to the android main screen and the app is minimized. If I go to all running apps (holding home button) I can return to my game and continue playing without any trouble. The problem is if I leave the app with home button and then i want to return to my app by clicking my game icon in android menu or "desktop".

Then the app crashes. The same things happen to big titles like Subway Surfers or Bad Piggies.

What is the problem here?

Thank you!

Peter

Maybe it is your device? I have ported to Android and I do NOT have this issue. Once I click the home button I can access my app by clicking the app icon or by clicking the little thumbnail preview when holding down the home button (in the "recent apps" view).

I ran a few tests, I can click the home button, open a new app, close that app, open yet another app, close that one, turn the screen off on my phone, wait 3 minutes, turn my screen on, then resume my app by clicking it's icon.

To be more specific: -My app was opened, started a new game and played for about 2 minutes [Hit the home button] -The first app I opened was open for about 5 minutes, and I closed out of it by hitting the back button till it closed. -The second app was open for about 1 minute and I clicked the home button instead of closing out. -Turned off screen for about 3 minutes -Turned screen on, waiting about 30 seconds -Clicked my app icon on my home screen -App was 100% where I left off. No crash, no reloading, just resumed.

My android device I tested this on was the Samsung Galaxy S3. I built my apk as a developer build and turned on script debugging.

My app uses ~140mb of RAM in this specific example.

Hello, thank you for all your answers but I think I steel cant identify my true problem. This thing happens on many of our test devices, but it does not happen every time. And when it has its "period" of doing such crashes, it repeats with other unity games too (bad piggies, subway surfers). This happens to those games even when my game is not running or is not installed on the device, so I dont think it causes other apps to crash. Sometimes I can run tests for hour and wont get the crash, but when it crashes it can crash 4-5 times in a row. The unpredictable nature of the crash is really weird. I guess it must really be the RAM thing, since it happens on all devices and on many apps and not every time.

I'll paste crash log later when I remove my apps data from it. Thank you,

Peter

@Madarina did you find a solution to the problem?

In my case the app always crashes when running in background and opened through app icon. However, works fine when accessed through recent apps screen.

Here is my log, unfortunately doesn't tell much.

if it is developer build then you can launch it once, second time it will not launch from icon again.
