StrictMode violation

[alexandre-thauvin]

Describe the bug Using version 11.1.1 of freeRASP making emulators get the ANR which has been fixed in version 11.1.3. This ANR was because of StrictMode violation. Despite this ANR not happening anymore in version 11.1.3, the StrictMode violation still occurs (cf logs)

To Reproduce Integrate freeRASP as normal integration

If you don't have the bug with a sample app I suggest to do some disk/file operations then you should have it

Expected behavior No StrictMode violation

Screenshots If applicable, add screenshots to help explain your problem.

Please complete the following information:

• Device: Google Pixel 7A
• OS version: Android 14 - API 34
• Version of freeRASP: 11.1.3
