Gear VR with a S6 Edge. When launching the app, it crashes. This was packaged on UE 4.10 Android ETC2. I am currently doing a Full Rebuild package option and will report back. I enabled Dev mode and exported the following logs (I added the bold text)

I just ran into this one myself on 4.10.4. A brief look at that assert in the code shows the filesize is not being regarded as big enough to be a zip file. I can only assume it’s looking at the .obb file, but in my case it’s well over 2GBs, which should pass the check. If you get any updates regarding this, let us know.

3

I have the similar issue on 4.10.2. My OBB is also over 2GBs. Could it be a bug that the obb file is too big to be correctly recognized?

4

I had the same problem and getting the obb file back under 2gb fixed it (ours is now 1.5gb). If i had to take a guess as to why this check fails:

void AddPatchFile(TSharedPtr<FFileHandleAndroid> file)
{
	
	int64 FileLength = file->Size();

	// Is it big enough to be a ZIP?
	check( FileLength >= kEOCDLen );

…

I would guess that file->Size(); is returning a signed 32bit value which overflows at about 2gb. resulting in a value of 0 or a negative number. which is less than kEOCDLen.
