RunTime.Exception 활동을 인스턴스화 할 수 없습니다. ComponentInfo

Question

안녕하세요 여러분, 저는 Android를 처음 사용하고 있습니다. 제발 도와주세요. 내 프로젝트에서 "Level Activity"의 "OyunActivity"를 시작하겠습니다.

난 그냥 그렇게 AndroidManifest.xml에 모든 활동을 추가 : 그러나 다음과 같은 오류가 나타 안드로이드 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> 

그리고 자바 빌드 경로에 라이브러리를 추가하여 문제를 해결하기 위해 시도 그러나 그것은 작동하지 않았다. 누군가는 이클립스로 인해 발생하는 문제라고 생각하지만 잘 모르겠습니다. 어쨌든, 프로젝트에서 내 LevelActivity.java 그렇게하고 문제가있는 경우 나는 여기에서 생각 :

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(); 

     } 
    }); 

} 
}

당신은 Activity의 본체에서이 작업을 수행 할 수

...

SharedPreferences preference = getSharedPreferences("TERCİHLER", MODE_PRIVATE); 

로 선언

SharedPreferences preference; 

는 ... 다음 onCreate(...)에 ...와 또 다른 점은이 작업을 수행하지 않습니다

preference = getSharedPreferences("TERCİHLER", MODE_PRIVATE); 

...

MainMenuActivity mma= new MainMenuActivity(); 

... 당신은 만들 수 없습니다를 환경 설정을 얻을 new을 사용하여 Activity의 인스턴스 그것은 단순히 작동하지 않습니다. 시도해 본적이없고 public 메서드 또는 변수를 Activity에 만들지 말고 작동하도록하십시오.
