ClassNotFoundException：K4LVideoTrimmerのcom.coremedia.iso.boxes.FileTypeBox

Question

ビデオを調整しようとしています。https://github.com/knowledge4life/k4l-video-trimmerと次のエラーが発生しました。私は様々なポストで示唆されているようにプロガードを変更しようとしました。しかし、まだ成功することはできませんでした。助けてください。あらかじめありがとうございます。

Answer 1

これはknown problem with Proguardです。次に、あなたの署名APKがクラッシュしなくなります

-keep class * implements com.coremedia.iso.boxes.Box {* ; } 
-dontwarn com.coremedia.iso.boxes.* 
-dontwarn com.googlecode.mp4parser.authoring.tracks.mjpeg.** 
-dontwarn com.googlecode.mp4parser.authoring.tracks.ttml.** 

：

この問題を回避するには、あなたのProGuardの-pro.cfgを編集して、これを追加することです。
