How to delete all Player Prefs on the Android device!!!

Hey everyone,

I have my game running on a android device and im using player prefs to save which ever level the player has completed (silver trophy will be unlocked). The levels also has a trophies system set up depending on which objective has been completed.

My problem is i have created a button to delete all of the player prefs from the game i.e. lock all of the unlocked levels again for testing purposes however i cannot get the game to delete everything i.e. gold trophy data gets deleted however the levels are still unlocked when they should be locked.

Is there any other way to delete all of the saved data (player prefs) on the android device????

This scipt is attached to a button and it works as it should in the editor however it does not work properly on the device.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class PlayerSavedDataDelete : MonoBehaviour
5. {
6.  
7.     void Start ()
8.     {
9.         PlayerPrefs.DeleteAll ();
10.     }
11.  
12. }

 

I'm guessing you're saving some data to disk? You should figure out what file that is and use System.IO.File.Delete(pathToFile); to delete it.

 

Unless I'm missing something, PlayerPrefs.DeleteAll should work. It's what it's there for. If it doesn't, I think you need to report this as a bug.

 

PlayerPrefs.DeleteAll() works fine I used it in my last 2 games which target android 4.x and it works every time.

 

Hi,
This problem seems to be frequent on some Android devices.
Anyway, you can remove each saved datas with PlayerPrefs.DeleteKey
If you don't know the name of every key you use, you can override functions of PlayerPrefs in order to store the keys list and then do something like this :
for (var key in storedKeys) {

PlayerPrefs.DeleteKey(key);​

}

 

I will research more on the link that you have provided. Thanks

 

I hope you are right, it is really annoying as i cant reset my only testing device. I might end up uploading a game that the levels stop working half way through, even though they seem to be working fine in the editor.

 

Hi, i have about 40 levels in my games which equates to many keys i will try to use your solution. Im somewhat relieved that it is kind of a common occurrence whats happening with my device.
