OutOfMemoryError in contentsOfFile method while loading stacktrace

[arcao]

Hi guys,

we started to use HockeySDK for the test releases in our app (currently SDK ver. 5.1.0, but it occurs on older versions too). We found several crash reports from one specific device, see bellow.

I guess some older crash has been created with too long stack trace and when HockeySDK is trying to send a crash report, it crash on OutOfMemoryError because the stack trace is too big to be loaded into memory.

Unfortunately this device doesn't belong us, so we can't check stack trace content stored by HockeySDK. Anyway I included a few examples of that crashes. Could you please check that?

Hi @arcao,

Thanks for getting in touch!
We are working on reducing memory usage. You can track progress in related PR.

Best,
Ivan

[MichalStranik]

Any progress? Our customer is getting crashes by tool which should help to fix crashes, not make them. Doesn´t look good.

[guperrot]

A fix was merged but the release is planned after the fixes related to Android P.

[ElektrojungeAtWork]

Hey!
We've included fixes in the latest SDK release (5.1.1) for this. I'm closing the issue but please reopen if you run into this again.

Thx for using HockeyApp!
