Crash on SDK initialize #4

Closed supermicut closed 2 years ago

supermicut commented 2 years ago

This might sound like a noob question, but: are there any dependencies that need to be taken into account when initializing the SDK ?

I have a project, blueprints only. The project is live on google play, without any other issues.

I'm using UE 4.27.1, AppLovin plugin 1.0.1.

With the demo project provided (no other plugins enabled) I have the same issue, no errors when building, just crash on SDK Initialize.

Thanks

Hi - do you have the crash's stack trace and exception message?

supermicut commented 2 years ago

Hi Thomas,

I think this should be what you need.

Thank you. We'll investigate when we have bandwidth - in the meantime it might be more efficient to debug on your end as well. Note that our plugin is already open source.

supermicut commented 2 years ago

Tried a lot of ideas the past few days ... and none worked for me. :-( Still ... I think I have made some progress. While reading the Verbose, I think I managed somehow to restrict the possible cause: W/System.err: java.lang.ClassNotFoundException: Didn't find class "com/epicgames/ue4/GameActivity$MaxUnrealPluginListener" on path: DexPathList[[zip file "......

Unfortunately, I really don't have the skills to fix this, or even to fully understand it :-)

PizzaPie144 commented 2 years ago

Getting exactly the same, any fix for this?

None form my side. I had to look for another provider.

ritamsarmah commented 2 years ago

Sorry about the delay—we're currently looking into this. For context, the MaxUnrealPluginListener is a helper class for Android defined in AppLovinMAX_UPL_Android.xml under the gameActivityClassAdditions tag, and is expected to be available as a result of that (the UPL file itself gets registered in AppLovinMAX.Build.cs). My hunch is it could be related to the configuration in those.

While we work on the issue, my initial suggestion for debugging in your own projects would be to remove the conditional guard tags around lines that require bEnabled to be true in AppLovinMAX_UPL_Android.xml to see if the necessary additions then get included for your project.

PizzaPie144 commented 2 years ago

So after changing the function FJavaAndroidMaxUnrealPlugin::Initialize in AndroidJavaMaxUnrealPlugin.cpp to

`void FJavaAndroidMaxUnrealPlugin::Initialize(const FString &PluginVersion, const FString &SdkKey) { JNIEnv *JEnv = FAndroidApplication::GetJavaEnv(true);

jobject activityObj = FAndroidApplication::GetGameActivityThis();

jclass activityCls = FAndroidApplication::FindJavaClass("com/epicgames/ue4/GameActivity");

jmethodID ListenerGeneratorID = JEnv->GetMethodID(activityCls, "GetNewMaxUnrealListener", "()Ljava/lang/Object;");

jobject LocalListener1 = JEnv->CallObjectMethod(activityObj, ListenerGeneratorID);

auto LocalListener = NewScopedJavaObject<jobject>(JEnv, LocalListener1);

CallMethod<void>(InitializeMethod, *GetJString(PluginVersion), *GetJString(SdkKey), *LocalListener);

}`

And in the Android_UPL file inside gameActivityClassAdditions

` public class MaxUnrealPluginListener implements MaxUnrealPlugin.EventListener { public native void forwardEvent(String name, String params);

      public MaxUnrealPluginListener() {}

      @Override
      public void onReceivedEvent(String name, String params)
      {
      forwardEvent(name, params);
      }
      }

      public  Object GetNewMaxUnrealListener(){
      MaxUnrealPluginListener listener = new MaxUnrealPluginListener();
      return listener;
      }
    `

Seems to work, not sure if any other bug is introduced though at this point. Anyway couldn't get it to recognize the MaxUnrealEventListener nor the EventListener classes which seemed to be the problem in the first place.

ritamsarmah commented 2 years ago

@PizzaPie144, thanks for sharing your findings. I haven't been able to replicate the issue in our demo app or a clean blueprint project, so it's been a bit difficult to verify a solution on my end.

Could you try updating the <proguardAdditions> in AppLovinMAX_UPL_Android.xml with the line shown below and letting me know if that works?

  <proguardAdditions>
    <if condition="bEnabled">
      <true>
        <insert>
-keep public class com.epicgames.ue4.GameActivity$MaxUnrealPluginListener { *; }
        </insert>
      </true>
    </if>
  </proguardAdditions>
