Hello.
It seems cisco anyconnect calls a function available only since android 4.4 (https://developer.android.com/reference/android/app/AppOpsManager#checkPackage(int,%20java.lang.String)).
Can't start app on android 4.3.
Package name: com.cisco.anyconnect.vpn.android.avf
Package version: 1790
Package version name: 4.8.03538
Device info:
Model: SM-N900
SDK version: 18
Will be happy to receive any help or info related to this case.
Ramil.
