PersistentDataPath saved files are not writing into android device?

Hello, so here is the thing: I have some couple of datas to recover during the game which is the game’s map (saved those datas using persistentDataPath); I can access to these data using the unity engine but when I built the app to apk and ran it on my android device, the datas didn’t wrote to android storage thus cannot play the game. I can however import the datas manually to android device and works fine. I want publish my game to Play Store i guess i have to solve this problem before publishing. PLEASE HELP…

please check your Android manifest. It will be in Assets/Plugins/Android/AndroidManifest.xml

Is there WRITE and READ data permission?

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

These two permission should be there in order to read data from file and to write data to the file

Hope it will help you
