我正在尝试为我的项目创建一个 发行版 。生成release-apk之后，在我安装并启动它时，会出现以下错误

但是当我在 调试版本 中运行相同的代码时，我没有收到此错误

在构建发行版时，proguard会显示一些警告，因为该应用程序在调试版本中运行良好，所以我在proguard-rules.pro中给出了〜ignorewarnings ，这可能是个问题吗？

代码：

    public class DemoApplication extends Application {
    ...
    }

AndroidManifest.xml

<application
    android:allowBackup="false"     
    android:largeHeap="true"
    android:name=".exoui.DemoApplication"
    android:testOnly="false">

java.lang.ClassCastException：com.tv.app.exoui.DemoApplication无法转换为android.app.Application
