java - Unity 插件在使用通知 Compat Builder 时出现错误

Question

所以，

我为 Unity 创建了一个通知插件，当我使用时它工作正常(Notification = New Notification.Builer)

但我想使用NotificationCompatBuilder来访问旧设备，这样它就可以在所有API级别中使用。

当我使用它并尝试运行它时，它给了我这个错误

是的，我已经使用了

import android.support.v4.app.NotificationCompat;

我正在使用 Android Studio 和 Library .aar 文件来统一构建插件

花了半天时间才解决这个问题，哈哈

编辑:将“com.android.support:support-v4:25.1.0”添加到 gradle 也没有解决问题。

Edit-2:我认为可以通过将“support-v4-25.1.0”(我从 SDK 文件夹中获取)添加到“Assets/Plugins/Android”来抑制该问题，但它仍然给我同样的错误我认为它仍然看不到 .aar 文件:我很困惑

Answer 1

更新和回答:好的，当我看到此日志错误时

android.support.v4.app.NotificationCompat$Builder

我虽然问题出在 support.v4.25.1.0.aar 文件上，但是当我添加 support-compat-25.1.0.aar 时，错误是消失了，现在它正在工作。并且不再需要support.v4.25.1.0.aar...
