RunTime.ExceptionアクティビティComponentInfoをインスタンス化できません

こんにちはみんな私はアンドロイドに不慣れです、私を助けてください。プロジェクトの「LevelActivity」から「OyunActivity」を始めたいです。しかし、次のエラーが表示されました。

AndroidManifest.xmlに次のようにすべてのアクティビティを追加しました：Android Manifest.xml

<activity
        android:name="com.example.hangdeneme.LevelActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.LevelActivity" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
    <activity
        android:name="com.example.hangdeneme.OyunActivity"
        android:label="@string/title_activity_oyun" >
        <intent-filter>
            <action android:name="android.intent.action.OyunActivity" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

そして、Javaビルドパスにライブラリを追加して問題を解決しようとしましたが、機能しませんでした。誰かが日食による問題だと思っていますが、私にはわかりません。とにかく、プロジェクトMy LevelActivity.javaはそれであり、問​​題がある場合はここにあると思います。

package com.example.hangdeneme;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class LevelActivity extends Activity {

public static String KATEGORI_NU="";
int kategoriNu=0;

ListView lisViewKategori;


String kategori[]={"bitki","hayvan","özel","şehir","film","müzik","marka","falan-filan"};
MainMenuActivity mma= new MainMenuActivity();



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_level);

    ArrayAdapter<String> adapterKategori = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,kategori);

    lisViewKategori = (ListView) findViewById(R.id.listView1);
    lisViewKategori.setAdapter(adapterKategori);
    lisViewKategori.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            kategoriNu=arg2;
            Intent intent= new Intent(LevelActivity.this,OyunActivity.class);
            intent.putExtra(KATEGORI_NU, kategoriNu);
            mma.menuMedia.pause();
            startActivity(intent);
            finish();

        }
    });

}
}
