ANR in Android App triggered by Java_com_scottyab_rootbeer_RootBeerNative_checkForRoot #224

Closed vayush750 closed 4 weeks ago

vayush750 commented 4 months ago

ANR (Application Not Responding) has been caught up in our Android App, where the main thread waited for too long causing the ANR. This has occurred multiple time.

Attaching the stack trace for reference -: `main (native):tid=1 systid=12526

From the docs

You can also call each of the checks individually as the sample app does. It is advisable to call isRooted() from a background thread as it involves disk I/O.
