我已将我想要首先从MainActivity运行的活动更改为另一个。我这样做是通过编辑Android清单并移动这段代码来实现的:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
我的清单现在看起来像这样:

当我在手机和平板电脑(从Android工作室)上运行时,我收到以下错误,应用程序会像以前一样自动启动。但是,当我点击图标时,它首先会以正确的活动正常启动。
但是当我使用模拟器时,正确的活动仅在首次安装时启动,然后先前设置的活动就会启动。
我不知道为什么会这样。我完全卸载了应用程序并重新安装,我清理了我的项目,重建了它,没有什么似乎有所作为,我在我的清单中找不到问题。有什么想法吗?

更改启动器活动后,您是否清理过项目?如果没有,那么可以解决你的问题。
答案 1 :(得分:0)
如果您使用的是Eclipse
,则可能需要Project
- &gt; Clean
您的项目。
如果您使用的是Android Studio
,则可以执行以下操作:Build
---&gt; Rebuild Project
或Clean Project
。也许缓存导致这样的事情。
PS:请参阅java.lang.SecurityException: Permission Denial: starting Intent
,您需要添加一些权限。
