Rejecting re-init on previously-failed class java.lang.Class<com.mixpanel.android.mpmetrics.InstallReferrerPlay>: java.lang.NoClassDefFoundError: Failed resolution of: Lcom/android/installreferrer/api/InstallReferrerStateListener;

[itaybia]

simple app with mixpanel shows the exception written below in the log (app doesn't crash).
app is only using: implementation "com.mixpanel.android:mixpanel-android:5.9.1"
the exception is shown on multiple Android 9 devices (OnePlus 6T, and Samsung Galaxy 9). Android 10 pixel device did not show the exception in the log.
this adds risk to our main app in case we upgrade from mixpanel 4.9.0 to 5.9.1 as we are not sure the implications of such a problem on various devices.

MainActivity code:
package ;
import android.app.Activity;
import android.os.Bundle;
import android.widget.LinearLayout;
import com.mixpanel.android.mpmetrics.MixpanelAPI;

public class MainActivity extends Activity {
@OverRide
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String projectToken = ;
MixpanelAPI mixpanel = MixpanelAPI.getInstance(this, projectToken);
LinearLayout layout = new LinearLayout(this);
setContentView(layout);
}
}

Stack Trace in log:

hi @itaybia . This is a runtime error and simply means the com/android/installreferrer/api/InstallReferrerStateListener is not available on the device's classpath. It won't cause the actual crash. However, if you want to remove the error, you can enable it by adding the following in your build.gradle:

dependencies {
        implementation 'com.android.installreferrer:installreferrer:1.1'
        ...
}

For more information: https://developer.mixpanel.com/docs/android#automatic-referrer-tracking

I'm closing this one now, feel free to reopen if you have any questions.
