Android error: cannot find symbol for java extension

[Wabbajackalope]

Greetings,

i am trying to create an extension so i can use appsflyer and have no real experience in how to use java

when i attempt to compile a blank game file with only a room and the extension in it i get the following errors.

Y:\com.companyname.Project2\src\main\java\com\companyname\Project2\AppsFlyerClass.java:24: error: cannot find symbol
		Map<String, Object> eventValue = new HashMap<String, Object>();
		^

  symbol:   variable AFInAppEventType
  location: class AppsFlyerClass

and here is the .java file im trying to use

package ${YYAndroidPackageName};

import android.util.Log;
import java.lang.String;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

import ${YYAndroidPackageName}.R;
import com.yoyogames.runner.RunnerJNILib;
import ${YYAndroidPackageName}.RunnerActivity;

import com.appsflyer.AppsFlyerLib;

public class AppsFlyerClass extends Activity 
{

	public void startTracking( String key, String app)
	{
		AppsFlyerLib.getInstance().startTracking(this.getApplication(),key);
	}

	public static void trackEvent(String level, String label, String score)
	{
		Map<String, Object> eventValue = new HashMap<String, Object>();
		eventValue.put(AFInAppEventParameterName.LEVEL,level);
		eventValue.put(AFInAppEventParameterName.LABEL,label);
		eventValue.put(AFInAppEventParameterName.SCORE,score);
		AppsFlyerLib.getInstance().trackEvent(context,AFInAppEventType.LEVEL_ACHIEVED,eventValue);
	}

}

does anyone know what im doing wrong and how to make the machine find the correct symbols?

thank you.

You haven't imported java.util.* and com.appsflyer.AFInAppEventParameterName, and context hasn't been defined.

Seriously, learn some basic Java before pressing ahead with this, or pay someone else to do it. There's a reason why virtually every book on Android development comes with a disclaimer that they assume prior Java experience.

ok i have made some headway, now im only having one error appear

Y:\com.companyname.Project2\src\main\java\com\companyname\Project2\AppsFlyerClass.java:24: error: cannot find symbol
public static void trackEvent(Context context, String level, String score)
                              ^
  symbol:   class Context
  location: class AppsFlyerClass

package ${YYAndroidPackageName};

import android.util.Log;
import java.lang.String;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

import ${YYAndroidPackageName}.R;
import com.yoyogames.runner.RunnerJNILib;
import ${YYAndroidPackageName}.RunnerActivity;

import com.appsflyer.*;

import java.util.*;

public class AppsFlyerClass extends Activity 
{
public void startTracking( String key, String app )
	{
	AppsFlyerLib.getInstance().startTracking(this.getApplication(),key);
	}

public static void trackEvent(Context context, String level, String score)
	{
	Map<String, Object> eventValue = new HashMap<String, Object>();
	eventValue.put(AFInAppEventParameterName.LEVEL,level);
	eventValue.put(AFInAppEventParameterName.SCORE,score);
	AppsFlyerLib.getInstance().trackEvent(context, AFInAppEventType.LEVEL_ACHIEVED, eventValue);
	}
}

im pretty sure i do need context in order to get this to function and its suppose to pull up the command

getApplicationContext()

but am shooting in the dark because when i try to pull that up it begins talking about static.

slowly but surely

thank you.
