Binary XML file line #7: Error inflating class fragment,

I have been learning fragment for the past few days. I want to write a program on my own and try it. I didn't expect it to be a problem when I first wrote it.

An error occurred while loading the main layout file activity_main.xml.

13:11:12-12. 873: E/AndroidRuntime (2022): java. lang. runtimeException: Unable to start activity ComponentInfo {com. gentleni. demo_grideview_002/com. gentleni. demo_grideview_002.MainActivity}: android. view. inflateException: Binary XML file line #8: Error inflating class fragment

06-12 13:11:12. 873: E/AndroidRuntime (2022): Caused by: android. view. InflateException: Binary XML file line #8: Error inflating class fragment

I checked the relevant information, and it turns out to be a fragment version Compatible problem.

Android. app. Fragment is compatible with android: minSdkVersion = "11", that is, version 3.0.

The Minimum Version compatible with android. support. v4.app. Fragment is android: minSdkVersion = "4", that is, version 1.6.

If the support. v4 package is used, fragment labels cannot be defined in xml. My xml code:

  <fragment        android:id="@+id/id_MYFragment"        android:name="com.gentleni.demo_grideview_002.MyFragment"        android:layout_width="wrap_content"        android:layout_height="wrap_content" />

The Fragment label is supported only when the new package android. app. fragment is used. This means that the fragment of v4 package cannot be statically loaded ???
