Android save / load file

Hello, I just made application that saves score into a text file, it works on PC but not on android. I also tried to search whole memory of phone but file wasn't made. In script is the same path for checking the file if it exist (if it doesn't, then it creates one at the same path as the app is loading and saving (path to file is string variable). Can you help me? Do I need to add some rights to this app to open that or it's just not working on a phone? I'm using System.IO.File.blablabla for working with files

 

Try the instructions in this video:
https://unity3d.com/es/learn/tutori...ining-archive/persistence-data-saving-loading

but instead of using ".dat" , use ".sav"

 

You could use playerprefs for example for saying and loading score,
its very simple when you get to understand it.

Code (CSharp):

1. //save score
2. void SaveScore(){
3. score +=1;
4. PlayerPrefs.SetInt("Score"score);
5.  
6. }
7. //load score
8. void LoadScore(){
9. int getScore = PlayerPrefs.GetInt("Score");
10. Score = getScore;
11. }
12.  
13.  

of course you will need to implement this into your own code

EDIT*

To check if the file exists then you will do the following

Code (CSharp):

1. //load score
2. void LoadScore(){
3.  
4. if(PlayerPrefs.HasKey("Score")){//the key has been found
5. int getScore = PlayerPrefs.GetInt("Score");
6. Score = getScore;
7. }else{
8. print("No Key Found");
9. }
10. }
