Android AdobeMobileLibrary 4.8.2 StrictMode crashes

[lionel_camacho]

Hi,

Our Android app makes use of the adobeMobileLibrary version 4.8.2. In our debug version of the app we run it using strict mode to ensure the app behaves correctly, but we are getting crashes from the adobeMobileLibrary when running in strict mode, please see the logs bellow and advise:

Please advise on when this would be resolved.

Hi Lionel,

We tried but couldn't reproduce this crash. It'd be better if you can provide us some more information on:

1. What's the device type and Android version you were using?

2. How frequent were you able to see this crash?

3. Is there a certain way that you can reproduce it?

Based on our investigation, we think it might be a bug of okHttp library, https://github.com/square/picasso/issues/296. And it only happens on Android 4.4.x during some edge cases. 

Thanks.
