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。应用程序在启动时使用以下堆栈崩溃并引用我没有的活动。我相信这是因为我（暂时）从清单中为我的应用程序有两个入口点，因此需要一个解析器（选择器）。

这是真的？

这是清单的一部分。注意 Welcome 和 Settings 活动。两者都有用于带有 Main 的 Launcher 的意图过滤器，这就是在开始活动之前需要“解决”的问题。显然其他安装程序只是抓住一个（随机，第一个等）？

    <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>

Having more than one Activity that matches on the intent-filter may require a Resolver to choose among the matching options. Remove one of the MAIN / LAUNCHER intent filters or add a Resolver with a chooser dialog to launch.
