【问题讨论】：
请贴出相关代码 您在清单文件中删除的内容。E/AndroidRuntime(786): android.content.ActivityNotFoundException: Unable to find explicit activity class hellog.diwesh.NugaBest/helog.diwesh.NugaBest.NotesList; have you declared this activity in your AndroidManifest.xml?
@Raghunandan：伙计，我已经发布了上一个问题中的所有代码。必须将两者分开，因为他的网站不允许我包含更多字符
@AnshSharma 您的包名称是 hellog.diwesh.NugaBest 但您在所有活动中声明，例如 helog.diwesh.NugaBest 您错过了 l .
【参考方案1】：
您尚未在清单文件中声明 NoteList 活动。
请将此包含在您的清单中。
希望对你有帮助！！
【讨论】：
【参考方案2】：Unable to find explicit activity class hellog.diwesh.NugaBest/helog.diwesh.NugaBest.NotesList; have you declared this activity in your AndroidManifest.xml?
这意味着您忘记在清单文件中声明您的NotesList activity，如果您声明了您的packagename在声明中会有问题，请在您的清单文件中交叉检查activity & package name并确认您声明正确.
【讨论】：
【参考方案3】：这里出错，你没有正确声明
<activity android:name="NotesList" android:label="@string/title_notes_list">
变成这样
<activity android:name=".NotesList" android:label="@string/title_notes_list">
你的包名错误你的包名是hellog.diwesh.NugaBest，但你在所有活动中声明，如helog.diwesh.NugaBest，据此更改。
【讨论】：
不要认为这是问题 检查一下，这是这里的问题。活动应该有包。 请检查此developer.android.com/guide/components/intents-filters.html。示例具有package="com.example.android.notepad"> 和活动条目为 activity android:name="NotesList" android:label="@string/title_notes_list">
@all 我做了更改，这就是新日志的样子以上是关于Logcat 错误描述：按钮启动使应用程序崩溃的主要内容，如果未能解决你的问题，请参考以下文章
Android - 应用程序启动时片段 onCreate 崩溃
发布 apk 安装但启动时崩溃。该应用程序在调试模式下完美运行。我查看了 Android Studio，这是我的 adb logcat。
