Question

我在Manifest中有以下活动：

android.intent.action

是否需要类别名称？关于Notification_bar( first activity)？我的意思是，我看到了很多教程，其中大多数都重复了关于建议名称的相同规则，以及我如何开始，我想知道我真正可以改变什么而不犯任何错误

Answer 1

是否需要类别名称？关于android.intent.action？

所有普通的Android SDK应用程序至少需要一个<activity> <intent-filter>结构，您的问题就在于此问题。那个<intent-filter>说＆＃34;嘿，主屏幕（以及任何其他表现得像发射器的东西），包括一个启动此活动的选项！＆＃34;。

如果您的清单中有两个或更多<activity>个元素，则所有这些元素都不需要<intent-filter>。大多数情况下，您并不希望想要所有人<intent-filter>。将它放在您的启动器活动上，并根据需要跳过（或更改）其他活动。

例如，在this sample app中，我定义了两个活动，但只有一个具有启动器<intent-filter>：

            </intent-filter>
        </activity>
        <activity android:name="OtherActivity"/>
    </application>

</manifest>
