java - Is there any way to load files on the android phone itself? -

i have made program scans phone using recursion find epub files located under "/storage/emulated/0/". works, , can load files found , turn them inputstream, cannot data them using this api. using same code load epub files assets folder works, however.

the code used turn file inputstream follows:

//example location     booklocation = "/storage/emulated/0/downloads/book.epub" assetmanager assetmanager = getassets();  //does not work inputstream bookstream = new bytearrayinputstream(booklocation.getbytes("utf-8"));  //works inputstream bookstream = assetmanager.open("book.epub"); 

you're wrapping booklocation string in bytearrayinputstream creates stream gives string when read from

what open fileinputstream on filepath in following way

new fileinputstream(booklocation); 

adding code

//example location     booklocation = "/storage/emulated/0/downloads/book.epub" setmanager assetmanager = getassets();  //does not work inputstream bookstream = new fileinputstream(booklocation);  //works inputstream bookstream = assetmanager.open("book.epub");
