Android M bugs

Unity Engine
1

So far I have been unsuccessful in getting Android M to work with Unity 4.6.7p4. Has anyone had any success with Android M? Here are the repro steps for the bug I am seeing. Unity QA is currently investigating the issue.

Repro: create a blank Unity 4.6.7p4 project, with an AndroidManifest.xml that targets sdk version 23. Launch game on a Nexus 6 with Android 6.0.

The following error log appears on startup.

E linker : readlink(‘/proc/self/fd/39’) failed: Permission denied [fd=39]

I believe this log error message is the reason that we are unable to load libraries, based on the following log that we are seeing in our game.

E linker : readlink(‘/proc/self/fd/61’) failed: Permission denied [fd=61]
E linker : warning: unable to get realpath for the library “/data/app/com.company.app-1/lib/arm/libjni.so”. Will use given name.

I Unity : at LocalNotificationManager.Start () [0x00000] in :0

Notes:
The game runs find on the same Android device, when targeting sdk 22.
I successfully granted myself the following permissions (the only group permissions we use) through the new Android 6.0 permissions system, and I still receive the same errors.
android.permission.GET_ACCOUNTS
android.permission.READ_PHONE_STATE
android.permission.WRITE_EXTERNAL_STORAGE

We had the same issue here. And we found that Android M did not give us storage access permission even we asked for it in AndroidManifest. Try enabling the storage access for the app from Android settings menu and see if it goes away.

We are still working on how to get the permission right. It seems to be a Android bug:

Hello, I created an issue here:

Hope Unity people will notice this soon.

Hi, I also experience this issue. I cannot push obb files anymore when using split apk using the Unity3d editor ‘run’. On my Android M device the obb downloader neither works also related to the permissions. Unfortunately I have to keep the targetSDK to 23 since I want to use the latest android facebook sdk.

I also voted on your report and also found this which might be related: Unity Issue Tracker - [Android/6.0] Failed to push OBB file onto Adnroid 6.0 device

We have a bug report for “Permission denied” issue, and will handle it as soon as possible.

Hello, I would like to ask whether this fix will be ported to Unity 4.6.X or not. Thank you.

@aaefiikmnnnr - yes we will likely port it back to 4.6.

Ugg, we’re having this issue in 5.1.4, but are unable to upgrade to 5.2+ due to several other bugs and problems we’ve encountered. Is there a way to get this fix in 5.1.4?

9

Looks like we can get away with this right now by disabling split binary… will use that for now.

10

@TitanUnity : patches for 4.6 and 5.2 are on the way. We no longer ship patches for 5.1: Unity Blog

I update unity to 4.6.9p3 and there is still this problem. I want to save image on External but nothing happens, apk don’t have permission but i add it in manifest. On older version ( < 6.0) works fine.

12

@breaker2005 : 4.6.9p3 should have the fix.
If the permission is in manifest, and it is considered “unsafe” by Google, - we should ask for it at startup.
If it’s not the case - please report a bug, attach the project and post the case #.

Was this fix added to any version of 5.X? We are having this issue currently. I am running 5.2.3f1.

14

All “M” fixes available at the moment should be available in:

  • final 4.x (4.7?) version
  • 5.2.4 final
  • 5.3.0p1 has most fixes but one small feature missing.
15

Is there a release window for 5.2.4?

16

I would expect it this week: http://forum.unity3d.com/threads/unity-patch-releases.246198/page-3#post-2416607

But Jawa is a better person to answer this question.

So what are people doing when the user chooses to deny a permission?

Some will create subtle and hard-to-detect bugs:

Others may kill the app entirely (for example, if the OBB downloader doesn’t have its required permissions)

Or is everyone just setting targetSDKVersion to <23?
