Android：启用<activity-alias>时PackageManager.DONT_KILL_APP无法阻止应用关闭

我创建了带有弃用启动图标的<activity-alias>，当收到后端返回的弃用错误时，启用该别名并禁用原启动入口。图标能按预期切换为弃用图标，但即使传入PackageManager.DONT_KILL_APP参数，应用仍会被强制关闭。

方案1：直接禁用原启动Activity #

核心代码 #

private fun disableDefaultIcon() {
    val defComponentName = ComponentName(applicationContext.packageName, LaunchActivity::class.java.name)
    packageManager.setComponentEnabledSetting(
        defComponentName,
        PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
        PackageManager.DONT_KILL_APP
    )
}

private fun enableDeprecatedIcon() {
    val depComponentName = ComponentName(applicationContext.packageName, "com.company.mon.AliasDeprecatedActivity")
    packageManager.setComponentEnabledSetting(
        depComponentName,
        PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
        PackageManager.DONT_KILL_APP
    )
}

方案2：使用双<activity-alias>分别对应默认/弃用图标 #

AndroidManifest配置 #

<!-- Activity Alias -->
<activity-alias
    android:name="com.company.mon.AliasDefaultActivity"
    android:enabled="true"
    android:targetActivity=".presentation.workflow.authentication.launch.LaunchActivity"
    android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity-alias>

<activity-alias
    android:name="com.company.mon.AliasDeprecatedActivity"
    android:enabled="false"
    android:icon="${round_deprecated_icon_path}"
    android:roundIcon="${round_deprecated_icon_path}"
    android:targetActivity=".presentation.workflow.authentication.launch.LaunchActivity"
    android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity-alias>

核心代码 #

private fun enableDeprecatedIcon() {
    val depComponentName = ComponentName(applicationContext.packageName, "com.company.mon.AliasDeprecatedActivity")
    packageManager.setComponentEnabledSetting(
        depComponentName,
        PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
        PackageManager.DONT_KILL_APP
    )
}

private fun disableDefaultIcon() {
    val defComponentName = ComponentName(applicationContext.packageName, "com.company.mon.AliasDefaultActivity")
    packageManager.setComponentEnabledSetting(
        defComponentName,
        PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
        PackageManager.DONT_KILL_APP
    )
}

两种方案均出现相同问题：图标切换成功，但应用直接关闭，无报错。已知这可能是PackageManager.DONT_KILL_APP的系统bug，求可行的解决方法。
