The issue is in managmentCommand method in OpenVpnManagementThread, In some cases management commandMethod is being run on MainThread which is causing the ANR.. You should access this method on background thread only..

Take a look at following methods releaseHoldCommand networkChange

shift the access to background only... and ANR will be resolved..

@Awaizhassan are you willing to share a fix for that since you already looked into it?

I am also facing this ANR. and this ANR occurs a lot. I am handling the connect button state properly. but still facing this ANR. Is there any way to resolve this?

[schwabe]

@aqeelmobify marking your post off-topic since you are probably not talking about my app

[aqeelmobify]

Facing this ANR alot on the play console. It's related to this library.
