从安装崩溃寻找ResolverActivity？

Question

我的一位同事试图从内部网站加载我的APK，然后从安装程序中打开它。应用程序在启动时会崩溃，并使用下面的堆栈并引用一个我没有的活动。我相信这是因为我（临时）从清单中为我的应用程序提供了两个入口点，因此需要解析器（选择器）。

这是真的吗？

这是一张清单。注意欢迎和设置活动。两者都有针对Launcher with Main的意图过滤器，这就是开始活动之前需要“解决”的问题。显然，其他安装程序只抓一个（随机，第一等）？

<activity android:name=".ui.WelcomeActivity" 
       android:label="@string/title_welcome"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 
      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity>    

    <activity android:name=".ui.AboutActivity" 
       android:label="@string/title_edit_profile"> 
     <intent-filter> 
      <action android:name="android.intent.action.VIEW" /> 
      <category android:name="android.intent.category.DEFAULT" /> 
     </intent-filter> 
    </activity> 

    <activity android:name=".ui.SettingsActivity" 
       android:label="@string/title_settings" 
       android:windowSoftInputMode="stateAlwaysHidden|adjustPan"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 
      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 
      <action android:name="android.provider.Settings.ACTION_SYNC_SETTINGS"/> 
      <category android:name="android.intent.category.DEFAULT" /> 
     </intent-filter> 
    </activity> 

Answer 1

在intent-filter上有多个匹配的Activity可能需要一个Resolver才能在匹配选项中进行选择。移除MAIN/LAUNCHER意图过滤器之一或添加一个带选择器对话框的解析器以启动。
