Unity 4.6 Beta RC3 - Blackscreen on Android 4.2.2

Unity Engine
1

Hello,

a user reported an blackscreen on start of my game. The error occurs on a Samsung Galaxy Tab 3 (GT-P5210) with Android 4.2.2 stock rom. But i cannot reproduce it on emulator (genymotion).

An another game with the same player-settings, but compiled with Unity 4.6 RC1, works fine on the galaxy tab.

My PlayerSettings:

Resolution and Presentation
Use 32-bit Display Buffer = true
Use 24-bit Display Buffer = true
Show Loading Indicator = Dont´t Show

Configuration
Graphics Level (OpenGL 3.0, 2.0) = Auto
Device Filter = FAT (ARMv 7+x 86)
Submit HW Statistics = true

Optimization
Api Compatibility Level = .NET 2.0 Subset
Enable Internal Profilder = false
Optimize Mesh Data = false

Publishing Settings
Split Application Binary = false

Does anyone have an idea?

Best regards

Well if you cannot reproduce then testing might be a bit difficult :wink: but I previously had some problems as well, might be entirely unrelated but try setting Graphics Level to force OpenGL ES 2.0 and see if that helps?

Edit: might not be a solution, but might narrow down the problem!

The user can test it for me :wink:
…i will send him an apk with OpenGL ES 2 and report again.

why not upgrade to final version.

MrEquire, thank you for the hint. I have not seen that the final version was released.

Hello,

i compiled the game with the final release 4.6 and sent it to the user.

  1. Apk with OpenGL 3.0
  2. Apk with OpenGL 2.0

But both apks occurs an black screen on start

Any idea?

…or does anyone have a tablet with Android 4.2.2 and would try run the game wether the black screen occurs too?

Here is the game:

Hi, I just tried on my phone (do not have any tablet) and it starts up fine here. As expected you might say since it is not a tablet. However though there is no black screen at startup, it does tend to crash after some time. I reported the crash so maybe you can see something from it :slight_smile:

Hi Ramsdal,

thank you. Here is your crash report :slight_smile:

Hmm, you use kitkat. I´m little bit confused :slight_smile:
I think its a general problem with the ugui:

Hi,
I’ve got the same issues with one of my users.
The error occurs on a Samsung Galaxy Tab 3 (GT-P5210) with Android 4.4.2 stock rom.
I was working on unity 4.5 but i did the update ( and some modifications ) and i didn"t work anymore.
So i reinstalled unity 4.5 and do a compilation.
I wait for the answer of the user and tell you if it’s working.

it’s working with unity 4.5 \o/
Si i hope that if i publish the version compile with unity 4.5 won’t break the game on other android version.

Maybe we should make thread on Android section on forum, because maybe not UI team issue.
We need Unity developer to see this and post bug report

12

are you using a mask? there is a mask bug on some androids where the mask just shows as the mask image instead

EDIT: never mind that is fixed now

13

I have Unity 4.5.4f1 installed and Unity 4.60f3. I have tested the same project files on a Motorola Droid Razr HD and a Samsung Galaxy Tab 3 in both Unity versions. The black screen occurs every time in 4.6 on both devices, but never occurs on 4.5.4. This issue is most definitely a Unity issue and is a massive concern for me as my client delivery is tomorrow… :frowning:

14

try 4.6p1 maybe… the bug i mentioned was fixed there

15

4.6p1? The version I have installed (4.6.0f3) is the latest version I get when downloading from the Unity website. Is there a different place to download version 4.6p1 from?

I’ll give that a try, thanks!

Also, for anyone else having this issue, a workaround I found for me was to not alter the quality settings on Android.
