How to open EPUB

[jdempcy]

This issue is a Question

Expected Behaviour

Open SDKLauncher-Android and be able to view an EPUB

Observed behaviour

Instead, it tells me that it cannot find any EPUBs at a certain location on the local storage (not SD card). I am unable to put files in that location as it is an illegal path.

Steps to reproduce

1. First, open SDKLauncher-Android
2. Then notice that it tells you to put EPUBs in /storage/emulated/0/epubtest which is an invalid path (since "0" is not a valid folder name)

Product

• Native application (Readium SDK C++)
  • Official "launcher" sample
  • Android—many versions; pulled from 'develop', June 10th 2016: version bump to 0.24.0-alpha

Additional information

Here is my original post to the Readium Slack channel

Has anyone gotten SDKLauncher-Android working lately? I’ve tested on a couple of devices and it gives me the toast message:

"/storage/emulated/0/epubtest is empty, copy epub3 test file please.”

However, I cannot create a folder named “0” as that is an illegal filename. And I have tried putting symlinks from within /storage to the SD card but they are apparently not followed. I have also tried changing the path where it looks to absolute paths on the SD card but again, no dice. I also added an intent to AndroidManifest.xml to be able to open EPUB with SDKLauncher-Android but I must’ve done it wrong, as it crashes when I try that.

Daniel solved this! Thanks, Daniel!

EPUBs must be placed within the SD card's "epubtest" folder. On my device, the path is "/sdcard/epubtest" — not "/storage/emulated/0/epubtest" as it was saying.

As soon as I placed EPUBs within the epubtest folder of the SD card, everything worked fine!

I've been bitten by this as well a couple times in the past.

Could the toast text be changed to more accurately specify the folder location? Is it OK to change it to "/sdcard/epubtest" or is that not always correct?

Sounds reasonable to me. I am OK with this change.

/storage/emulated/0/epubtest vs. /sdcard/epubtest
(same destination, different filesystem mount on some devices)
...the woes of Android FS, symbolic links, Java API etc.

but yes, I agree that the error message needs to help the user / tester fix the problem.
