我是android中的Instant app的新手,并在以下链接中供参考: https://codelabs.developers.google.com/codelabs/android-instant-apps/#6
可安装的apk和具有单一功能的即时应用程序正常运行。
但是当我尝试运行多功能即时应用程序时,它会崩溃(从上面的链接开始执行步骤7)。
崩溃报告:

请帮我解决这个崩溃。
答案 0 :(得分:3)
经过这么多尝试后我发现了问题。
问题是由于使用android.support.v4.app.Fragment
将android.support.v4.app.Fragment
改为android.app.Fragment
之后。
答案 1 :(得分:2)
IncompatibleClassChangeError
。请参阅What causes java.lang.IncompatibleClassChangeError?(但这可能不是您问题的真正原因)
你在什么步骤之后得到了崩溃?
但是,我现在看到的是,您的功能gradle文件具有以下依赖项implementation project(':topeka-base')
,而它应该包含api project(':topeka-base')
。 (假设你的功能gradle = topeka-ui gradle)
托皮卡-UI /的build.gradle
将所有预先生成的依赖项替换为 以下依赖:
dependencies { api project(':topeka-base') }
请仔细检查codelab说明,确保您没有错过任何步骤。
