启动主题导致重启

Launch theme causing reboot

我想充分利用 "cold start" 时间,展示一个品牌发布主题,正如所描述的那样 in this post。 我遵循了每一步,但在启动应用程序时,仿真器和真实设备都会进行热重启。 我相信这与我在应用程序中使用的 Google Play Services 有关。 我也尝试了 运行 this 项目,它遵循上述 post 并且不包括播放服务,一切都很好,所以它与设备无关。 这是一些代码:

Manifest.xml

<application
    android:theme="@style/AppTheme">
    <activity
        android:name=".MainActivity"
        android:theme="@style/AppTheme.Launch">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

styles.xml

<style name="AppTheme.Launch" parent="AppTheme" >
    <item name="android:windowBackground">@drawable/bg_launch</item>
</style>

bg_launch.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android"

<item android:drawable="?android:windowBackground" />
<item>
    <bitmap android:src="@drawable/ic_logo"
        android:gravity="center" />
</item>

错误发生在 bg_launch.xml,在 android:drawable="?android:windowBackground"

正在将 <item> 更改为

<item>
<shape android:shape="rectangle">
    <solid android:color="@color/grey_50" />
</shape>
</item>

以某种方式让它发挥作用。
