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

Question

Я пытаюсь интегрировать видео-обрезку https://github.com/knowledge4life/k4l-video-trimmer и сталкивается с следующей ошибкой. Я попытался изменить proguard, как это было предложено в разных сообщениях. Но еще не удалось. Пожалуйста, помогите. Спасибо заранее.

Answer 1

Это known problem with Proguard.

Чтобы обойти эту проблему, чтобы изменить Proguard-pro.cfg и добавить:

-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.** 

Тогда ваш подписал APK не врезаться.
