GoogleCodeExporter commented 9 years ago 
how often is this happening? Also, what is the app that this is in?

GoogleCodeExporter commented 9 years ago 
it doesn't happen often. the dev console reported it 4 times over about a 
month. that accounts for a few thousand users. 

the app is called Unlock With Wifi

i didn't post the entire report last time. sorry about that. here's the whole 
thing.

This issue happened to me as well.

My solution was to put the first request for isRootAvailable into a thread. 
This is anyway better, because if the user is prompted for root access the app 
will block.

isRootAvailable is a blocking command, as stated above it should be used within 
a thread.

Most static "conveniance" methods within RootTools are blocking and should be 
used within a thread.
