如何解决致命异常:颤振中的AsyncTask #2

Question

我使用的是video_editor软件包。当我处于调试模式时，它可以工作并且没有错误，但是当我释放apk时，应用程序会发生冲突并显示错误：

有人知道如何解决这个错误吗？

Answer 1

请检查所有必需的依赖项都包含在pubspec.yaml中的“依赖项：”中。在"dev_dependencies:“中声明的依赖项不包含在发布的应用程序中。

Answer 2

将以下条目添加到proguard-rules.pro文件中。如果您没有这个文件，您可以创建并放入app文件夹。

-keep class com.arthenica.mobileffmpeg.Config {
    native <methods>;
    void log(long, int, byte[]);
    void statistics(long, int, float, float, long , int, double, double);
}

-keep class com.arthenica.mobileffmpeg.AbiDetect {
    native <methods>;
}
