Crash in PostObjectAsync on Android #91

Closed flarb closed 8 years ago

flarb commented 8 years ago

Trying to use PostObjectAsync to an S3 bucket -- in the editor I don't get a crash, the post is successful, on Android PostObjectAsync crashes the app.

karthiksaligrama commented 8 years ago

Hi @flarb can you paste stack trace here?

flarb commented 8 years ago

So I posted another issue--which I think is the same one. I get these null pointer exceptions only on Android--they work fine in editor. I think these may we what's causing the crashes? I'll get you a stack trace if I can next.

Just clicking the ListObjects button on the demo on Android gives me these exceptions (it works fine in the Editor):

This is the output from logcat--which isn't much of a stack trace. But the happens when I call PostObject:

karthiksaligrama commented 8 years ago

thanks. can you also tell me what version of unity are you using and also if this is using android il2cpp or mono backend?

designzoo-peter commented 8 years ago

I am also crashing on iOS, with Unity 5.1, using mono backend. There is no stack trace posted in XCode unfortunately. In IL2CPP iOS uploads without a crash.

When I use Mono with iOS, I get the following console logs (with some of the text strings snipped out):

jdmiranda commented 8 years ago

you can increase the number of trampolines inside of zcode. its iOS specific. those are used for reflection inios. things like json parsing use trampoline. also they don't get garbage collected so they are there for full app life cycle.

karthiksaligrama commented 8 years ago

go to Player Settings > Other Settings and set the AOT option to nimt-trampolines=512

karthiksaligrama commented 8 years ago

Assuming problem is solved. Closing issue. Please reopen if problem persists
