Playing a video in VideoDetailFragment and rotating the screen to landscape (back and forth more often)
can trigger this error message. Especially if rotation for whatever reason takes long or
playing a high resolution (1080p) video.
The underlying logcat error messages:
05-12 16:38:38.251 24920 26037 E Surface : getSlotFromBufferLocked: unknown buffer: 0x923fc810
05-12 16:38:38.251 24920 26037 W ACodec : [OMX.qcom.video.decoder.avc] can not return buffer 35 to native window
The problem is that that Exoplayer is trying to write to our -- during rotation -- no longer existant
(VideoDetailFragment) SurfaceView.
Solution:
Implementing SurfaceHolder.Callback and using DummySurface we can now handle the lifecycle of the Surface.
How?: In case we are no longer able to write to the Surface eg. through rotation/putting in
background we can set a DummySurface. Although it only works on API >= 23.
Result: we get a little video interruption (audio is still fine) but we won't get the
'Unrecoverable player error occurred' error message.
This implementation is based on and more background information:
'ExoPlayer stuck in buffering after re-adding the surface view a few time 2703'

* re-work finished mission database
* re-work DownloadMission and bump it Serializable version
* keep the classic Java IO API
* SAF Tree API support on Android Lollipop or higher
* add wrapper for SAF stream opening
* implement Closeable in SharpStream to replace the dispose() method
* do required changes for this API:
** remove any file creation logic from DownloadInitializer
** make PostProcessing Serializable and reduce the number of iterations
** update all strings.xml files
** storage helpers: StoredDirectoryHelper & StoredFileHelper
** best effort to handle any kind of SAF errors/exceptions
