java.lang.RuntimeException: A TaskDescription's primary color should be opaque

android开发中，当theme的colorPrimary，colorPrimaryDark，colorAccent等涉及到颜色的属性使用了透明度，就会报错

java.lang.RuntimeException: A TaskDescription's primary color should be opaque

例，白色使用了透明度

<item name="colorPrimary">#00FFFFFF</item>

将其改成

<item name="colorPrimary">#FFFFFF</item>

设置属性

<item name="android:windowIsTranslucent">true</item>
