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.(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
• App language: Java, Kotlin
• Android R or API 30 (Tested on pixel 2 emulator)

This issue disappeared when I added below dependency which is already present in your build.gradle in my library build.gradle file. But I should'nt add this its logically invalid my library isn't using below dependency. implementation 'androidx.preference:preference:1.1.1'

[prcaen]

This issue occurs only in 1.1.3

[mmobin789]

@prcaen is there any updated version you are using ? Kindly suggest.

The library still says its last version at bintray is 1.1.3

[prcaen]

We are using the 1.1.2

same as above...

E/AndroidRuntime: FATAL EXCEPTION: main java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/preference/PreferenceManager;

The resolution is to add the following dependency: implementation 'androidx.preference:preference-ktx:1.1.1'

I could be wrong here, but it looks like VendorIdentifier is only used by BackgroundReporter. So if you are not interested in using background reporting, then the code could be slightly re-written to avoid this additional dependency. Only if background reporting is enabled do you need to persist TRUSTKIT_VENDOR_ID. As the code is now, everyone has to save this whether or not they want to.
