我正在尝试在当前的Android应用程序中使用SliceProvider。
每当我尝试使用内置的SliceProvider向导时，它都会失败并显示以下消息：-
Error executing FreeMarker template
FreeMarker template error:
The following has evaluated to null or missing:
==> activityClass [in template "root://other/SliceProvider/root/src/app_package/SliceProvider.java.ftl" at line 86, column 61]
Tip: If the failing expression is known to be legally null/missing, either specify a default value with myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthessis: (myOptionVar.foo)!myDefault, (myOptionVar.foo)??
The failing instruction (FTL stack trace):
----------
==> ${activityClass} [in template "root://other/SliceProvider/root/src/app_package/SliceProvider.java.ftl" at line 86, column 59]
----------
Java stack trace (for programmers):

我不应该使用此Android Studio功能吗？
我未在Android Studio中安装/更新哪些内容导致此问题
SliceProvider是否“准备就绪”？
我已经通过Google创建了一个issue
