声明时清单中缺少活动

Question

如图所示，有两个箭头.. 一个表示我的项目中的活动 另一个表明建议活动在清单中声明.. 但除了“StreamingActivity”之外没有推荐的活动 当我运行我的应用程序时，应用程序向我显示该消息“不幸的是，应用程序已停止”

此发布的代码

Answer 1

删除这个活动，因为你只使用了一个活动来定义活动，另外两个是碎片。

    <activity android:name=".S"/>
    <activity android:name=".Sub"/>

和片段调用在代码下面使用..

         Fragment fragment = new HomeFragment();
        getSupportFragmentManager().beginTransaction()
                .replace(R.id.fragment_frame, fragment, fragment.getClass().getSimpleName()).addToBackStack(null).commit();

Answer 2

无需在清单上声明片段，从清单中删除片段声明，因为您在清单文件中的部分内声明了片段。
