[Bug]: OneSignal .net-android error in Initialize call. Java.Lang.NoSuchMethodError #89

IainS1986 · 2024-01-18T09:59:53Z

What happened?

Updgrading a Xamarin Native to .net-android and .net-ios project.

Added OneSignalSDK.DotnNet/5.0.2

OneSignal.Initialize("MY KEY");

This line then errors with...

Java.Lang.NoSuchMethodError

Steps to reproduce?

1. Create new .net-android project
2. Add the OneSignalSDK.DotNet/5.0.2 nuget
3. Add the Initialize line to your first/main Activity
4. Run

It initialises.

Ok, this is an R8 shrinker issue.

I've tried adding some custom proguard rules but I'm struggling to get it to work.

-keep public class com.onesignal.** {;}
-keep interface com.onesignal.** {;}

Works to get past the basic method missing errors but then I get the following Java.Lang.Exception...

Service interface com.onesignal.core.internal.operations.IOperationRepo could not be instantiated

I thought the keep interface line above would resolve this but it didn't. Any ideas what rules are needed?

IainS1986 · 2024-01-23T10:20:24Z

Does anyone have working, R8 shrinker rules for OneSignal on Android?

I've tried using older proguard rules from here https://github.com/OneSignal/OneSignal-Android-SDK/blob/main/OneSignalSDK/onesignal/consumer-proguard-rules.pro#L51 but this isn't working with R8 shrinking.

Turning off R8 works fine, I'm sure our older Xamarin native project using OneSignal was R8 shrinking so this seems a specific problem in the new .net-android SDK support.

Can't seem to get the R8 not to break whatever it is that implements IOperationRepo

[mono-rt] java.lang.Exception: Service interface com.onesignal.core.internal.operations.IOperationRepo could not be instantiated
[mono-rt] 	at com.onesignal.common.services.ServiceProvider.getService(ServiceProvider.kt:70)

IainS1986 · 2024-02-27T11:53:16Z

Is there anyone from OneSignal able to advise on how to use this SDK with R8 shrinking on Android?

Example Repo of the issue (using MAUI)

https://github.com/IainS1986/OneSignal-R8-Test

This is a basic MAUI template (from Rider).

One Signal 5.1.1 added
One Signal intialisation same as your documentation
Release Configuration -> R8 Enabled
Proguard.cfg file added with all the proguard rules from all the Android modules found.

When I run a release configuration build to my phone I get the same exception…

FATAL EXCEPTION: main
Process: com.companyname.mauiapp1, PID: 1221
java.lang.RuntimeException: Unable to create application crc64e632a077a20c694c.MainApplication: java.lang.Exception: Service interface com.onesignal.core.internal.operations.IOperationRepo could not be instantiated

rmayrink · 2024-03-31T17:13:54Z

Same problema here...

ghost · 2024-04-08T13:58:30Z

I had to add this instruction to my Proguard file to fix it:
-keepattributes Signature

IainS1986 · 2024-04-08T14:12:47Z

When I try adding that I'm getting a whole bunch of R8 errors "A type or variable is not in scope."

Can you share your whole proguard file?

ghost · 2024-04-08T14:17:12Z

OneSignal - Proguard ends up removing this class even if it is used in AndroidManifest.xml so force keeping it.

-dontwarn com.onesignal.**

OneSignal - These 2 methods are called with reflection.

-keep class com.google.android.gms.common.api.GoogleApiClient {
void connect();
void disconnect();
}

-keep class com.onesignal.** {*;}
-keepattributes Signature

Keep methods annotated with @JavascriptInterface for webview bridge (InApp feature)

-keepclassmembers class * {
@android.webkit.JavascriptInterface *;
}

End OneSignal

ghost · 2024-04-08T14:18:01Z

It seems only this was enough for my project. At least for initializing the onesignal.

IainS1986 · 2024-04-08T14:19:30Z

Cheers, mayhbe theres something else in my proguard colliding with this, i'll try removing bits and adding bits and see how I go, cheers for pointing this line out though 👍

ghost · 2024-04-08T14:20:19Z

My project is Xamarin and it's using the version 5.0.2.

IainS1986 · 2024-04-08T14:21:44Z

Might be the difference too, this is specifically about .net-android 8+ (which you'll have to port over too soon). Hard to tell thought 🤷

ghost · 2024-04-08T14:24:20Z

I don't think it doesn't change much because it's using the onesignal android 5.0.3. It should be the same.

IainS1986 · 2024-04-08T14:26:15Z

Proguard effects your entire app. Not just onesignal. So it might fix it, but adding that line breaks some other sections in my proguard that (may) be needed for .net-android, I can't say for sure so will need some time to go through things bit by bit. I think it broke an AndroidX section in my proguard but will see.

I tried to change your maui test app using this configuration.

IainS1986 · 2024-04-08T15:19:14Z

When I'm refering the my proguard file thats breaking I'm not referring to that test project, that was for the OneSignal team to investigate.

The proguard file I have in another app is much larger. But I'll dig more into it but won't be happening for a week or two

IainS1986 · 2024-04-08T15:20:28Z

I narrowed it down to the following lines that break with the keepattributes Signature line,

-dontwarn androidx.**
-keep class androidx.** { *; }
-keep interface androidx.** { *; }

So I need to figure out the exact bits of AndroidX to keep as opposed to an (ugly) blanket keep on the whole thing

IainS1986 · 2024-04-17T11:50:20Z

Ok. After a lot of head banging I think I've resolved the issue.

So as @arctouch-rafaelpontes above pointed out, you do need to have this in your proguard,

-keepattributes Signature

But, you might (like me) have the following your proguard

-keep class androidx.** { *; }

These two lines do not work together. Ideally, you shouldn't be just having keep on the whole androidx, but its a faff not doing that if you need it. However you'll need to work out all references you are using in androidx and only include those. This is not fun.

Thankfully, someone did a lot of leg work already around this issue they were having with a different library here
dotnet/android#7008

So from this, I managed to make the following proguard that works, you might have some things still fail that you need to add, but this should work.

# OneSignal

-keep class com.onesignal.core.** { *; }

-keep class java.util.** { *; }

If all you want is the specific OneSignal rules

# OneSignal
-keepattributes Signature
-keep class com.onesignal.** { *; }
-keep class com.onesignal.core.** { *; }
-keep class com.onesignal.session.** { *; }
-keep class com.onesignal.user.** { *; }
-keep class com.onesignal.internal.** { *; }
-keep class com.onesignal.debug.** { *; }
-keep class com.onesignal.common.** { *; }
-keep class ** implements com.onesignal.common.modules.IModule { *; }

tbh, this might be enough

# OneSignal
-keepattributes Signature
-keep class com.onesignal.** { *; }

Thanks @IainS1986 for this tip. That got my app back in working order.

OneSignal - Proguard ends up removing this class even if it is used in AndroidManifest.xml so force keeping it.

OneSignal - These 2 methods are called with reflection.

Keep methods annotated with @JavascriptInterface for webview bridge (InApp feature)

End OneSignal
