我在我的Crashlytics中发现了这个错误,看起来它只对具有预览版
Android Nougat的用户而言是崩溃的.
应用程序在启动时崩溃(主要活动).
堆栈跟踪

看起来Android Nougat不再支持我在我的应用程序中使用的某种系统颜色？但我不确切知道如何解决它.
编辑
所以我在我的R文件中找到了ID为0x7f020057的资源,这就是它：
public static final int background_splash_gradient=0x7f020057;
我检查了我在哪里使用它,这里是：
<style name="StartingWindowTheme" parent="AppTheme">
<item name="android:windowBackground">@drawable/background_splash_gradient</item>
<item name="android:colorBackground">@drawable/background_splash_gradient</item>
</style>
这是background_splash_gradiend xml文件：
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:angle="135"
android:endColor="#00d49e"
android:startColor="#00bcd4"/>
</shape>
我仍然不知道为什么这会引起牛轧糖问题.我尝试删除“StartingWindowTheme”样式,应用程序现在可以正常工作,它不再崩溃.但我需要一个更好的解决方案.

所以我试图删除这一行：
<item name="android:colorBackground">@drawable/background_splash_gradient</item>
它有效.好像是android：colorBackground就是问题所在.
临时修复
由于问题出现在上面提到的行中,仅在Nougat上,我创建了一个values-v24文件夹并删除了那里的行. App现在适用于Nougat,但我希望有更好的解决方案.
