我想充分利用＆＃34;冷启动＆＃34;时间显示品牌发布主题，完全按照in this post所述。 我遵循了每一步，但在启动应用程序时，emualtor和真实设备都会进行热重启。 我认为这与我在应用中使用的Google Play服务有关。 我尝试运行this项目，该项目也跟在上面的帖子中，并没有包含游戏服务，而且一切都很好，所以它与设备无关。 这是一些代码：
的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"
android:opacity="opaque">
<item android:drawable="?android:windowBackground" />
<item>
<bitmap android:src="@drawable/ic_logo"
android:gravity="center" />
</item>

答案 0 :(得分：0)
错误发生在android:drawable="?android:windowBackground"的bg_launch.xml中。
将<item>更改为
<item>
<shape android:shape="rectangle">
<solid android:color="@color/grey_50" />
</shape>
</item>
以某种方式使它发挥作用。
