Unity in-app purchase not working on android device ?

Hi i just added UNITY IAP in my project. In play mode everything is working fine and purchase method called. But when i run the app on my android device i didn't see google purchase pop dialog. I haven't publish the app in beta testing yet but at least you can get the google purchase pop up with error.

so when i call the purchase method on android phone , nothing happens . Please help me .

 

Hi may I ask, because I use different plugin for IAP before. then I updated to 2018 unity then I use the IAP services.
but when I tried in mobile it doesnt work. my first IAP plugin work. is it maybe I didnt upload the new one? with new IAP services. does that connect at all?

thanks

 

@JeffDUnity3D Hi thank you for your reply I will double check my implementation.

BTW, maybe you can answer this topic which is really troubling in deploying to android.

Hey I am troubles with my IAP buttons.

I updated my Unity to the latest as well as the IAP catalogue. On IOS it works fine but on android it doesn't function well and the Purchase buttons have shifted.

I tried on my own android device and only the last 2 buttons work but they have the information of the previous two.
I have tried recreating my IAP buttons and deleting my googleplay services plugins as well.

I have no errors in my Unity compiler or Android SDK.

Do you know what the problem could be?

 

I am having the same problem but my app has been fully published and released. I released it without the IAP due to I didn't want to miss my release date and then did an update a couple days later with the IAP active. It works perfect when testing in play mode but after publishing, the purchase button does nothing, like the button has no function at all. I've verified on friends devices and Google accounts to be sure it wasn't just an issue with being logged in under the same email as the developer.

 

Also my IAP is set up correctly and everythingbut it isn't showing any dialogue window when i press on my buttons. Please tell me there is a fix coming or someone has a solution!

 

Hi i have the same issue.
I'm using Unity 2019.2.11f
I have tried accessing the IAP using codeless IAP and from script, the current project uses codeless IAP.
Attached is my log file.
A heads up, i use powershell to make the log file since i somehow can't redirect command prompt, and i have to kill the adb process via another window of powershell, just confused because the log file is small.

Thanks

 

i am stuck with same problem. i am using unity 2018.4.3. i delete the plugin and import again from unity services window and my game is already published with iap on play store but it is working on unity engine but not on android device

 

[Alpha test already published and testing on a phone]
I did that , and i have logs file attached.

i have 2 problems :
1- IAP is not working , i can't understand why from the logs.
2-unity ads aren't working either , it says in the log that "Unity Ads show failed: Unity Ads is not initialized".
in unity ads , i have this Advertisement.Initialize(Googleid, testMode);
testMode is set to false. is this wrong for alpha testing ?

 

Thank you so much.

 

so i tried to reimport IAP , and it didn't ask me to update my API .
i attached a new logs file and an image for the IAP says that its up to date.

 

I believe i was using IAP 1.23.4
i tried to remove IAP and kept getting a lot of errors , even though after solving these errors and reinstalling IAP , the update your API window never appeared.
so i created a totally new empty project with a different unity ID and installed IAP but the window didn't also.

should i uninstall unity w reinstall it again ?

 

i fixed it thank god.
i was using unity 2019.1.2f1 so i upgraded it to unity 2019.4.6f1 and reimport IAP and it worked.

 

Not working for me, Using 2021.3. Game just crashes upon pressing the IAP button.

 

I used Coded IAP and that is working instead of codeless like you said. For codeless, I ran logcat but it did not gave me any error, it just crashed without any information. Problem has been sorted out by simply coding the IAP.
