所以，
我为Unity创建了一个Notification插件，它在我使用时工作正常（Notification = New Notification.Builer）
但是我想使用NotificationCompatBuilder访问旧设备，因此它可以在所有api级别使用。
当我使用它并尝试运行它时会给我这个错误

是的，我已经使用
了import android.support.v4.app.NotificationCompat;
我正在使用Android Studio和Library .aar文件来构建统一插件
试图解决这个问题半天几乎是lol
编辑：添加＆＃34; com.android.support：support-v4：25.1.0＆＃34; gradle也没有解决它。
编辑-2：我认为可以通过添加＆＃39; support-v4-25.1.0＆＃39;来解决问题。 （我从SDK文件夹获得）到＃34;资产/插件/ Android＆＃34;但它仍然给我同样的错误我认为它仍然没有看到.aar文件：我很困惑
答案 0 :(得分：0)
更新＆amp;回答：好的，所以当我看到这个日志错误时
android.support.v4.app.NotificationCompat $生成器
我虽然问题出在 support.v4.25.1.0.aar 文件中但是当我添加 support-compat-25.1.0.aar 错误时走了，现在它的工作。而且不再需要 support.v4.25.1.0.aar ......
