How to check the path on Android

Hello So, I try to access to some XML file on my Android application. I put them in my StreamingAssets folder and recovering them by Application.streamingAssetsPath.

This is my code for getting the path:

 int index=0;
 index=m_RuleBaseFilePath.LastIndexOf("/");
 string path= m_RuleBaseFilePath.Substring(index,m_RuleBaseFilePath.Length-index);
 TextAsset textAsset = (TextAsset)Resources.Load(path, typeof(TextAsset));
 string realpath=Application.streamingAssetsPath+path;

This code works in the editor and for windows but not for Android when i try to build and run. I ask myself if i get the good path with this method.

Thanks for your help.
