Android Settings - Write Access: Internal Only vs External

I am sorry @JuliusM but I don't think it is working the same way (in Unity 5.4 nor in Unity 5.5).
As I said we are on Unity 5.5.1f1 and in production I had to implement that workaround to be able to save the game (i.e.: have a working and accessible path to save data) on some devices and avoid UnauthorizedAccessException .
Please also note that I don't think that the issue with the "extra code" implemented in Unity 5.3 and 5.4 is related as this issue happens also on new devices (i.e.: fresh installs).

 

UPDATE: I implemented the code @Tanek shared from github. I will post if I get anymore exception errors. The only piece I did not implement was the last fallback option if for whatever reason the first item in _persistentDataPath array is not writable. I didn't add this because the code already checks if the path is writable before adding it to the array so I didn't see a need for it. I want to thank @Tanek for his help in this thread. Hopefully this puts an end to this issue.

 

Hi there,

same problem here. I get the correct path from the code-example which @Tanek provided (thx for that), but i do have the Access Denied Exception. My device is Kindle Fire HD 8, maybe there's a similar problem like with the huawei-devices, but there is no possiblity (known to me) to change the "default storage location". Anyone any suggestions?

 

I'm used Unity 5.5.2f1 for a game I just released. I set the write permission to "internal", and I see in my bug reports that some devices (Huawei LON-AL00 and WIKO SUNSET2) get an IOException when trying to save data in the persistentDataPath pointing to their external storage. They are on Android 4.4 and supposedly don't need a special permission (from what JuliusM wrote). What is going on?

 

@Yury-Habets sorry to revive this thread, but are you sure? I'm on Unity 5.6.2p4, and the issue that everyone is discussing in this thread still exists, and @Tanek 's solution is the only thing that I see as currently viable. Is this ever going to be fixed in Unity?

 

Has anyone been able to confirm that latest Unity versions have fixed this? Would love to ship an update that allows saving on external storage.

 

same problem here, any solution for this? also was using easy save 2.. its now happening on every device.. im using 5.6.2f1 unity

 

Using Unity 2017.3 and building for Android 4.4+ :

Can anyone confirm that when a user switches the default storage location to the SD Card via Device Settings, the app saves work as expected (even if the app has no write to external permissions)?

Do we still need to implement @Tanek's code suggestion for a flexible persistentDataPath?
Thanks!

 

Hello,
I am using Unity 2018.1.1f1
I am building for Android with the following Player Settings:
Minimum API : 19
Install Location: Prefer External
Write Permission: External


The directory was created on the external storage when the app is installed (/SD card/Android/data/[package-name]/files/)

When I log Application.persistentDataPath I get the path to the internal storage (/Internal storage/Android/data/[package-name]/files/).

I get the same result even after change the default app location to SD card

Please let me know what to do as I am making an app that play 360 videos so internal storage is not an option

Thanks

 

Guys, I have the same issue when trying to save a file to sdcard(external drive), saving on internal storage(primary drive) is ok, but on sdcard was denied. Using version Unity 2018.1.8f1, so any can help? @Yury-Habets

Code (CSharp):

1. UnauthorizedAccessException: Access to the path "/storage/84FE-1AE1/Songs/FILE-SAVING.osu" is denied.
2. System.IO.FileStream..ctor (System.String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, Boolean anonymous, FileOptions options) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.IO/FileStream.cs:354)
3. System.IO.FileStream..ctor (System.String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize)
4. (wrapper remoting-invoke-with-check) System.IO.FileStream:.ctor (string,System.IO.FileMode,System.IO.FileAccess,System.IO.FileShare,int)

Hello! My users complain about a problem with the game that arises from the recording in Application.persistentDataPath.

Unity 2018.1.0f2 (64-bit)
Device: Oppo CPH1859 (8.1)
Device: OnePlus3T (OnePlus3T) (8.0)

Code (CSharp):

1.  
2.             string filepath = Application.persistentDataPath + "/" + "database.db";
3.  
4.             if (!File.Exists(filepath))
5.             {
6.  
7.                 WWW loadDB = new WWW("jar:file://" + Application.dataPath + "!/assets/" + "database.db");
8.                 while (!loadDB.isDone) { }
9.                 File.WriteAllBytes(filepath, loadDB.bytes);
10.                 dbConnection = (IDbConnection)new SqliteConnection("URI=file:" + Application.persistentDataPath + "/" + "database.db");
11.             }
12.             else
13.             {
14.                 dbConnection = (IDbConnection)new SqliteConnection("URI=file:" + Application.persistentDataPath + "/" + "database.db");
15.             }

I was stupid when I thought that it would work everywhere.

What is the output for the moment?
