Accessing local system ( File Browser )
How to access a file from local system using Application. For example how can i access a photo from my system for uploading .
Application class won't help you in this case. To access local files you have to use other classes like WWW or standard .NET classes like File, BinaryReader, etc.
Regarding uploading: please take a look at this answer from Bunny83

i've got the solution. I got a free plugin for file browser . C# File Browser in Asset Store. The code is

using System;
using System.IO;
public class testFileBrowser : MonoBehaviour {
//skins and textures

//initialize file browser
FileBrowser fb = new FileBrowser();
string output = "no file";
private string defaultFileDirectory = "/sdcard/DCIM/Camera";
// private string defaultFileDirectory2 = "/sdcard/DCIM";
// private string defaultFileDirectory3 = "/sdcard";
// private string defaultFileDirectory4 = "/";
// Use this for initialization
void OnEnable () {
//setup file browser style
print("bbhbh");
fb.guiSkin = skins[0]; //set the starting skin
if(Directory.Exists(defaultFileDirectory) )

fb.setDirectory(defaultFileDirectory);

The Application class does not have a way of loading files from the local file system. Instead you could use the WWW class with the file:// protocol in a coroutine like this:
public IEnumerator LoadImageFromLocalFile()
{
WWW www = new WWW("file://" + pathToLocalFileWithExtension);
yield return www;
Texture2D texture = www.texture;
}
Keep in mind that the image must be either .png or .jpg.
More on the WWW class here: WWW
Thanks to both the above answers. @LijuDeveloper's method needs @GameVortex's method to complete the process.
ImageFiles are not getting loaded on Android. Any reason? Am using www method.
