启动 Activity 时出错

Answer 1

问题可能出在您的 list 文件中。检查 AndroidManifest.xml 文件。

检查您的 Activity 声明中是否存在这些 intent-filters。如下所示。

<activity
     android:name=".main.SplashScreenActivity"       
     android:label="@string/app_name"
     android:screenOrientation="portrait">
     <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
     </intent-filter>
 </activity>

如果存在此信息，则可能发生了缓存问题。然后，试试这个:

Go to File -> Invalidate Caches / Restart...
