[9.4.3]Android crash :When app receives a notification. Unable to instantiate receiver io.maido.intercom.PushInterceptReceive

[fenngzui]

java.lang.RuntimeException: Unable to instantiate receiver io.maido.intercom.PushInterceptReceiver: java.lang.ClassNotFoundException: Didn't find class "io.maido.intercom.PushInterceptReceiver".. Caused by: java.lang.ClassNotFoundException: Didn't find class "io.maido.intercom.PushInterceptReceiver"

[fenngzui]

Flutter version 3.32.7 firebase_messaging: ^15.2.4

[fenngzui]

Our app has a lot of notifications for our own business, which originally had nothing to do with intercom. However, after I updated the intercom SDK, when I received the app's own notifications on the Android app (eg: someone follow me notification), the system crashed here.: @deepak786
java.lang.RuntimeException: Unable to instantiate receiver io.maido.intercom.PushInterceptReceiver: java.lang.ClassNotFoundException: Didn't find class "io.maido.intercom.PushInterceptReceiver".

How to fix this.

[deepak786]

@fenngzui Not sure what is the issue. Could you please share your AndroidManifest file?

[Ganzkiller]

After upgrading the Intercom SDK, the same issue occurred, there is no declaration of PushInterceptReceiver in AndroidManifest. Could this be related to the obfuscation rules in proguard-rules.pro?

[deepak786]

I believe it is because of the Obfuscation. See https://stackoverflow.com/q/50392706

Are you using any Proguard rules at the moment? Please share.

[deepak786]

I tested with the following Progaurd rules and its working fine.

-keepattributes SourceFile,LineNumberTable # Keep file names and line numbers.
-renamesourcefileattribute SourceFile
-keep public class * extends java.lang.Exception  # Optional: Keep custom exceptions.

The above rules are saved under file proguard-rules.pro. And this is how they are applied in Gradle file

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

[KestasVenslauskas]

It's happening on development env where we have no obfuscation

[deepak786]

@KestasVenslauskas Can you please share the MVP of the issue? So that I can check if something is wrong in Gradle configuration, etc.

[deepak786]

Can anyone please tell me up to which intercom_flutter version this is working fine?

Note: in intercom_flutter: 9.3.2, firebase_messaging dependency version was updated from 23.3.1 to 24.1.1. See https://github.com/v3rm0n/intercom_flutter/pull/534

[KestasVenslauskas]

@deepak786 I reverted back to 9.3.1 where the last time it was working normally, but looks like right now it crashes the in the same way. Maybe the underlying SDK is broken?

[deepak786]

Did you try the flutter clean?. Because maybe it is still using the updated version.

[KestasVenslauskas]

@deepak786 Flutter clean helped to make it work with 9.3.1 will try newer versions

[KestasVenslauskas]

@deepak786 Looks like intercom_flutter: 9.4.4 works after flutter clean

[deepak786]

@deepak786 Looks like intercom_flutter: 9.4.4 works after flutter clean

Based on this, I suggest everyone to try the flutter clean.

@deepak786 will this resolve Android crash related to java.lang.IllegalStateException also?
