Cannot find Android Class

Unity Engine
,
1

Hello,

I wrote my own simple plugin that returns a method. The package name is the same as my bundle identifier.
I have confirmed that it is in my .jar file. It also resides in Plugins/Android

MUST I also create a custom AndroidManifest.xml? The android class does not extend any unity activities. It’s a simple class.

Am I missing any important steps? I’ve wasted 6 hours on this already.

.cs

using(AndroidJavaClass activityClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
        {
            AndroidJavaObject activityContext = activityClass.GetStatic<AndroidJavaObject>("currentActivity");
            using(AndroidJavaObject pluginClass = new AndroidJavaObject("com.unlockable.adtracking.UnlockableAdTracking"))
            {
                if(pluginClass != null)
                {
                    pluginClass.CallStatic("setContext", activityContext);
                    result = pluginClass.CallStatic<bool>("adTrackingEnabled");
                }
            }
        }

Java:

package com.unlockable.adtracking;

import android.content.Context;

import com.google.android.gms.ads.identifier.AdvertisingIdClient;
import com.google.android.gms.ads.identifier.AdvertisingIdClient.Info;
import com.google.android.gms.common.GooglePlayServicesNotAvailableException;
import com.google.android.gms.common.GooglePlayServicesRepairableException;

import java.io.IOException;

public class UnlockableAdTracking
{

    private static Context context;
    public static void setContext( Context ctxt )
    {
        context = ctxt;
    }
   
    public static Boolean adTrackingEnabled() throws IllegalStateException, GooglePlayServicesRepairableException
    {
        Info adInfo = null;
        try
        {
            adInfo = AdvertisingIdClient.getAdvertisingIdInfo( context );
        }
        catch (IOException e)
        {
            //Unrecoverable error connecting to Google Play services (e.g.,
            //the old version of the service doesn't support getting AdvertisingId).
        }
        catch (GooglePlayServicesNotAvailableException e)
        {
            // Google Play services is not available entirely.
        }
 
        return adInfo.isLimitAdTrackingEnabled();
    }
}

Could it be you are lacking the gms classes? If you do it would fail to link at runtime and throw a ClassNotFound error.

i seem to have imported them all.

5

Do you see any error messages in the logcat?

Btw, strictly speaking you don’t need an AndroidJavaObject since you are only accessing static functions. AndroidJavaClass should do just fine.

Only a class not found exception

Try decompiling your apk to see if the class is bundled correctly.
