Loading files to /mnt/sdcard or /storage/emulated/0/ or /mnt/asec

[aaor...@gmail.com]

Hello!

I used this example to load files http://puravidaapps.com/filebyfile.php

My first tested phone has sdcard, thats why: strPath = /downloads/do-not-delete/

listFilename (amount of this files is big): 

• myfile1.csv, 
  
• myfile2.mp3, 
  

To read myfile1.csv I used FILE READ sourse: /downloads/do-not-delete/myfile1.csv

To read myfile2.mp3 I used PLAYER sourse: /mnt/sdcard/downloads/do-not-delete/myfile2.mp3

But another tested phone has an itegrated (emulated) sdcard (LENOVO VIBE X)  which adress is: /storage/emulated/0/

Previous FILE READ sourse and PLAYER sourse stopped to work.

Thats why: strPath (was not changed) = /downloads/do-not-delete/

FILE READ sourse: /downloads/do-not-delete/myfile1.csv

PLAYER sourse: /storage/emulated/0/downloads/do-not-delete/myfile2.mp3

QUESTION: 

How to correct str Path, FILE READ sourse and PLAYER sourse that app works properly on phones: 

• with sdcard 

and 

• with integrated sdcard 

and 

• if phone has a slot for the sdcard but the card is absent, files should be written and read in/from memory of the phone (as I understood: /mnt/asec)?

this

file:///storage/emulated/0

should be the same as this more general direction

file:///mnt/sdcard

to read a csv file with the file component, this path should work for you for both devices /downloads/do-not-delete/myfile1.csv

I just tested this on my Nexus 5 successfully

to play a mp3 file, I would suggest to use the full path, which is in your case file:///mnt/sdcard/downloads/do-not-delete/myfile2.mp3

try again and let us know, if it works for you

I've just tried. 

But for LENOVO VIBE X (Android 4.2.2.) /mnt/sdcard/downloads/do-not-delete/myfile2.mp3 don't works.  LENOVO VIBE X haven't slot for sdcard (see photo #1)

It works only for HTC Desire V (see print screen #2) which has real sdcard

just read again what I wrote...

to play a mp3 file, I would suggest to use the full path, which is in your case file:///mnt/sdcard/downloads/do-not-delete/myfile2.mp3
