Android: build issue with 9.0.5 or later

[kevin-do-zimplistic]

Like title say, I couldn't run Android when upgrade to the latest version. The previous one (9.0.4) run fine so I think it's the problem with Intercom 15.9.0 Android sdk.

But the weird thing is: I created a new Android native project and used Intercom 15.9.0 sdk. It runs completely fine. Maybe it's a problem on your configuration or I have to change some setting in my build.gradle file?

Anyway, here's the error. Thanks in advance

I see errors only with these 2:

I have both.

Getting the same error. Have locked the version as of now.

[gmcdowell]

I'm trying to support both platormrs and am stuck having to use 9.0.4 for Android and 9.0.6 for iOS.
Please fix ASAP as this is affecting our userss

[deepak786]

Could you please test the example app and see if it is running fine?

[kevin-do-zimplistic]

Tested the example app, it works.

I found the problem. We have to update the Gradle version to the same version in the example app. Closing the issue now

[Bojan227]

@kevin-do-zimplistic what file/files did you update?

[kevin-do-zimplistic]

@kevin-do-zimplistic what file/files did you update?

The gradle-wrapper.properties file, 2 build.gradle files. And depend on your current packages, you have to upgrade the packages in pubspec.yaml to latest version as well.

[Bojan227]

@kevin-do-zimplistic Thank you.
I downgrade my gradle version from 8.7 to 8.5 and upgraded Android Gradle Plugin from 7.3 to 8.1.4

[benjamincombes]

Same here, we've been blocked with a major release for 4 days now, so it was at a very high business cost... Once the fix is out, it might be nice to add some tests to be sure such issues don't occur again? But glad a solution is on its way 🙏!

[greatschism]

Any luck with this situation?

[nikorehnback]

Is using gradle 8.5 safe solution since below Flutter doc states that supported gradle version goes up to 7.6.1 ?

Personally I run it fine.

I don't think that doc states that "supported gradle version goes up to 7.6.1". What it said is that if we use Gradle version > 7.6.1, we may have to change the Android file structure.

[kevin-do-zimplistic]

Any luck with this situation?

I already posted my solution. Doesn't it work for you?

[benjamincombes]

Yes but actually, it means all builds will fail for most people using Intercom. No one knows the failing builds comes from Intercom. So if, by chance, people find this issue with a Google / Github search, and use the solution, that's nice. But a fix would really be needed for all other users, who'll have no more Android builds because they didn't get that link 😅

[Korpyc]

Dear intercom_flutter dev team, wtf?!?
I spent a day of my work before I found reason of this issue, this tread not searchable via google!

Why such change not mentioned in changelog???
And why it was even done, rest of packages not do this breaking change with this major update of gradle

[eertmanhidde]

Hope this helps anyone:

Solution for me was disabling R8 full mode with android.enableR8.fullMode=false in gradle.properties

what is full mode?

In non-compat mode, also called “full mode”, R8 performs more aggressive optimizations, meaning additional ProGuard configuration rules may be required.

You need to use AGP version 8. Please follow the below steps:

• android/app/build.gradle
  Make sure to add the following under android section

    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = '1.8'
    }

• android/gradle/wrapper/gradle-wrapper.properties
  Update your distributionUrl

distributionUrl=https\://services.gradle.org/distributions/gradle-8.5-bin.zip

• android/settings.gradle

id "com.android.application" version "8.1.4" apply false
id "org.jetbrains.kotlin.android" version "1.9.21" apply false

For ref see this commit: 6cd517b

[deepak786]

Repening as other users are facing the similar issues

[deepak786]

It seems that Intercom Android SDK v15.9.0 has some dependency updates. So it requires AGP 8. As it is the same issue with react native version also https://community.intercom.com/mobile-sdks-24/react-native-android-build-failed-rn-0-72-14-intercom-7-1-3-7398

• If you want to use intercom_flutter: 9.0.5 or later, see this comment to update to AGP 8.

• If you cannot update to AGP 8 at the moment, use intercom_flutter: 9.0.4.

[olivierkastel]

I have the same issue and i'm unable to compile the app for Android.
And i also spent a lot of time finding this github issue... 😅

[gabulcw]

I have the same issue here. I use Flutter 3.19.6
