Open .epub file from internal storage (getFileStreamPath) #377

Open benthemobileguy opened 5 years ago

benthemobileguy commented 5 years ago

I saved a file to my internal storage with this path: file = getFileStreamPath(fileName); I am attempting to access the file with this line of code but it keeps crashing my app each time:

FolioReader folioReader = FolioReader.get(); File file = getFileStreamPath(fileName); Log.e("file: ", "file: " + file.getAbsolutePath()); folioReader.openBook(file.getPath());

This is the error it gives: Unknown book file extension fileName. What do I do?

mahavir155 commented 5 years ago

folioReader.openBook(file.getPath()+ "/title");

Why "/title"?

benthemobileguy commented 5 years ago

I just edited my question. please review

mahavir155 commented 5 years ago

Is the filename is with epub extension?

benthemobileguy commented 5 years ago

yeah. it has the .epub extension.As a matter of fact it opens up from the asset folder. I want to post more of my stack trace error. that I think might be useful.

This error is thrown when the epub file you are trying to open doesn't exist on that path.

benthemobileguy commented 5 years ago

So, how do I get the reference to this path?

--getFileStreamPath(fileName);

mahavir155 commented 5 years ago

You are opening the book which is in Assets? or which is in your SD card?

benthemobileguy commented 5 years ago

I am opening the book from my internal storage

benthemobileguy commented 5 years ago

the documentation does not explain how to open epub files from android internal storage

mahavir155 commented 5 years ago

it's as simple as calling folioReader.open(sdCardPath) Can you check the path of the file and that file exist in your android device on that path?

benthemobileguy commented 5 years ago

it exists. but I still keep getting the error

benthemobileguy commented 5 years ago

I finally resolved my issue. I discovered from my device file explorer that my files were saved as .txt instead of .epub extension. After converting them, it worked smoothly with this code:

var path: String = context.getFilesDir().getAbsolutePath()

Thanks for your effort!
