Video descriptions can be very long. Some of them are
basically walls of text with couple of lines at top or bottom.
They are also not scrolled within TextView itself, - instead
NewPipe expects user to scroll their containing ViewGroup.
This renders all builtin MovementMethod implementations useless.
This commit adds a new MovementMethod, that uses requestRectangleOnScreen
to intelligently re-position the TextView within it's scrollable container.
FocusFinder has glitches when some of target Views have different size.
Fortunately LayoutManager can redefine focus search strategy to override
the default behavior.
GridLayoutManager is buggy - https://issuetracker.google.com/issues/37067220:
it randomly loses or incorrectly assigns focus when being scrolled via
direction-based navigation. This commit reimplements onFocusSearchFailed()
on top of scrollBy() to work around that problem.
Ordinary touch-based navigation should not be affected.
* migrate few annotations to androidx
* mission recovery: better error handling (except StreamExtractor.getErrorMessage() method always returns an error)
* post-processing: more detailed progress
[file specific changes]
DownloadMission.java
* remove redundant/boilerplate code (again)
* make few variables volatile
* better file "length" approximation
* use "done" variable to count the amount of bytes downloaded (simplify percent calc in UI code)
Postprocessing.java
* if case of error use "ERROR_POSTPROCESSING" instead of "ERROR_UNKNOWN_EXCEPTION"
* simplify source stream init
DownloadManager.java
* move all "service message sending" code to DownloadMission
* remove not implemented method "notifyUserPendingDownloads()" also his unused strings
DownloadManagerService.java
* use START_STICKY instead of START_NOT_STICKY
* simplify addMissionEventListener()/removeMissionEventListener() methods (always are called from the main thread)
Deleter.java
* better method definition
MissionAdapter.java
* better method definition
* code cleanup
* the UI is now refreshed every 750ms
* simplify download progress calculation
* indicates if the download is actually recovering
* smooth download speed measure
* show estimated remain time
MainFragment.java:
* check if viewPager is null (issued by "Apply changes" feature of Android Studio)
* OggFromWebMWriter: rewrite (again), reduce iterations over the input. Works as-is (video streams are not supported)
* WebMReader: use int for SimpleBlock.dataSize instead of long
* Download Recovery: allow recovering uninitialized downloads
* check range-requests using HEAD method instead of GET
* DownloadRunnableFallback: add workaround for 32kB/s issue, unknown issue origin, wont fix
* reporting downloads errors now include the source url with the selected quality and format
