java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/preference/PreferenceManager;

Describe the bug Below exception is thrown when I init the trust kit for android using below line TrustKit.initializeWithNetworkSecurityConfiguration(context) java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/preference/PreferenceManager; at com.datatheorem.android.trustkit.utils.VendorIdentifier.getOrCreate(VendorIdentifier.java:24) at com.datatheorem.android.trustkit.TrustKit.<init>(TrustKit.java:209) at com.datatheorem.android.trustkit.TrustKit.initializeWithNetworkSecurityConfiguration(TrustKit.java:321) at com.datatheorem.android.trustkit.TrustKit.initializeWithNetworkSecurityConfiguration(TrustKit.java:271)

To Reproduce There are no steps just the init line causes this issue and this issue has nothing to do with network_security_config and thats added under application tag in app’s manifest and in xml directory under res. The pattern for my base url is added and I am using 64 char length pinset. My network config is below for ref.

Expected behavior I want to implement SSL pinning for Android 21 and above.

TrustKit configuration <?xml version="1.0" encoding="utf-8"?> <network-security-config> <domain-config cleartextTrafficPermitted="false"> <domain includeSubdomains="true">abcd.abcd-abcd.com</domain> <pin-set> <pin digest="SHA-256">XXX</pin> <pin digest="SHA-256">XXX</pin> <pin digest="SHA-256">XXX</pin> </pin-set> <trustkit-config enforcePinning="true" /> </domain-config> </network-security-config>

App details:

• App target SDK: 30
• App Min SDK: 21
