Get file list from a directory on Android
Hello !
I looked for a while here and I can't find a solution to my problem :
I got some files in a subfolder in resources. At runtime, I want to dynamically create some list according to the files name. On editor no problem here.
But I can't find any solution on android because WWW can't access to a directory, it works only when we have the full path (and i can't do that here because it would be the opposite of what I'm trying to do).
Anyway, is this true ? I only see old post, is there a new unity solution to getFiles from directory on android ?
If not, I think that I can get the file's list before building on Android. But I don't want to launch a first time on editor, list everything in a new file and then build on android with this file included, because the list can change at each build ... So, is that possible to write code on pre processor ? I mean, when i click on File > Build & run, is it possible to launch a script that stored my files name and after build on Android with that new file / list.
I don't know if i make myself clear, tell me
Thanks for reading, hope someone already thought about that.

It works on on Android Platform Also. Make sure you are you are passing the path correctly.
string path= Application.persistentDataPath + "/MyFolder/";
DirectoryInfo dataDir = new DirectoryInfo (path);
try {
FileInfo[] fileinfo = dataDir.GetFiles ();
for (int i=0; i<fileinfo.Length; i++) {
string name=fileinfo [i].Name;
Debug.Log("name "+name);
}
} catch (System.Exception e) {
Debug.Log (e);
}
Oh really ? Where should I put my folder ? For now it's in the Resources folder, and i can't find it on android.
Should i use strea$$anonymous$$gassets folder ?
It didn’t work.... directory. Get file doesn’t work on android...

I solved the problem after I added my files in this directory inside the projec Assets/StreamingAssets/
then I read it inside the code
#if UNITY_ANDROID
string path = "jar:file://" + Application.dataPath + "!/assets/alphabet.txt";
WWW wwwfile = new WWW(path);
while (!wwwfile.isDone) { }
var filepath = string.Format("{0}/{1}", Application.persistentDataPath, "alphabet.t");
File.WriteAllBytes(filepath, wwwfile.bytes);
StreamReader wr = new StreamReader(filepath);
string line;
while ((line = wr.ReadLine()) != null)
{
//your code
}
#endif

If the files are local this should work:
https://msdn.microsoft.com/en-us/library/07wt70x2(v=vs.110).aspx
On Editor yes; it works like this :
DirectoryInfo levelDirectoryPath = new DirectoryInfo(dbPath);
FileInfo[] fileInfo = levelDirectoryPath.GetFiles("*.*", SearchOption.AllDirectories);
foreach (FileInfo file in fileInfo)
{
// etc etc
}
But it doesn't work on Android
