Can you explain us a bit more about the issue? Is it the same as the one explained in this issue? If yes, can you send us the stack trace? Can you reproduce the issue and if yes, what are the steps?

Guys, we are having the same problem. We updated from 4.11 to 4.12 and now we get the following stack trace. We use unity 5.6.4p2
Here is the stack trace:

@acalandriJC

Can you tell us how do you reproduce this issue? Which Unity version are you using, which Adjust SDK version?

[acalandriJC]

Sure, we are using unity 5.6.4p2 with adjust sdk 4.12 (we updated from 4.11).
Basically we have the adjust object on scene and when we hit play when tries to initialize it the error occurrs. It does not make the game crash, but its weird since in 4.11 was working just fine and no exceptions were shown.

[uerceg]

Are you running it in Editor maybe?

[acalandriJC]

This happens when we click play on the editor, yes, but this wasnt happening in 4.11

[uerceg]

Ah, interesting, okay. I mean, those methods are not even supposed to be executed in Editor environment for our SDK. I will prepare one demo SDK version soon and post it in here so that you give it a try and let us know if you're still facing the same issue and if not, we'll make official SDK update, if you're willing to give it a try?

[acalandriJC]

Sure! Thanks!

[acalandriJC]

Also, dont know why is this happening, but after upgrading adjust, ios low end devices crash when before they wouldnt. Just tried to revert adjust to 4.11 and the game works fine. As soon as i update to 4.12 the same device with the same build with updated adjust crashes on open. The device we are trying it on is an ipad 3. Don't know if could be the same thing or not. Just know that updating to 4.12 is proving to be harder than it should. Thanks for the help though :)

@acalandriJC

Hm. Would it be possible for you to give our upcoming release RC version a try (you can find it in here: #119 (comment)) and let us know if it solved your issue you saw with iPad 3?

[acalandriJC]

Sure! We will give it a shot and report back with the results, thanks!

[acalandriJC]

@uerceg Success!!! Whatever you guys did fixed all the issues, the editor errors and the crashes on ios. When can we hope to see a new official release with this fixes?

[uerceg]

🎉 Official 4.12.2 is being prepared and should be live soon. I hope tomorrow at latest point. Will update in here once live.

Sorry late to reply,I use Unity Editor Mode with Andriod platfrom and Clikc play,
The error is showing,
I think this code have problem
AdjustAndroid.cs line:16
"private static AndroidJavaClass ajcAdjust = new AndroidJavaClass("com.adjust.sdk.Adjust");"

but I correct run in android device.
