RePlugin version:

Android compile SDK version:

Android ROM: Caused by: java.lang.ClassCastException: class com.jeff.demo.repluginpatch.PluginFragment cannot be cast to android.support.v4.app.Fragment at java.lang.Class.asSubclass(Class.java:2340) at com.jeff.demo.repluginhost.MainActivity.initFragment(MainActivity.java:50) at com.jeff.demo.repluginhost.MainActivity.onCreate(MainActivity.java:37) at android.app.Activity.performCreate(Activity.java:6679) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1118)

插件用得是v4包下得Fragment,为什么会出现这个问题呢？

Research direction
Investigate the ClassCastException caused by attempting to cast a plugin Fragment to android.support.v4.app.Fragment. The issue likely stems from a version mismatch between the support library used in the host app and the plugin, or incorrect use of the Fragment class. Check the RePlugin documentation for guidelines on using fragments in plugins, and verify the support library versions in both host and plugin modules. Also, review the comments in the issue for any additional context or solutions suggested by maintainers.
