I have an application with a lot of media data (images and videos) that
were previously stored on the sdcard. With that, images and videos are
displayed fine in my app.
Now, in order to secure the content more, I wanted to move the content
to the internal storage / data dir of the app, which I did. I copied all
media with a routine within my app to the data folder
(/data/data/com.myapp/some/folders/video.mp4) and adjusted the path in
my app so that it would look for the media in the internal storage data
directory and not the sdcard anymore.
Everything works fine, images are being displayed (decoded) properly,
but videos don't play. They files do exist though - I do not get a
FileNotFound exception. But an IOException:
java.io.IOException: Prepare failed.: status=0xFFFFFFFC
Why is that? Everything is handled within my one app and the videos have
been copied with the same routine as the images, thus having the same
permission settings. Looking at the stack trace, it all runs in process
id 18060).
Why I cannot playback the video from internal storage? Or how can I? Thanks.
