Android GC_CONCURRENT 및 사운드 박스 앱 개발

Question

첫째, 영어로 내 레벨을 유감스럽게 생각합니다.

도움이 필요합니다. 나는 앱 (버튼을 클릭하고 사운드를들을 수있는 사운드 박스)을 개발하려고합니다. 나는 아무런 문제가 없었지만 노래를 한 후에 나는 기억 상 문제가있다. 내 기록은 다음과 같습니다.

어떻게 해결할 수 있습니까? 두 개의 탭을 넣었지만 노래는 첫 번째 탭에 있습니다. 여기에 코드 자바입니다 : 처음에 사실

public class MainActivity extends TabActivity { 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     // Gestion des onglets 

     // Tout d'abord on récupère les ressources qui seront utilisés plus tard : 
     Resources res = getResources(); 
     // On prépare les éléments nécessaires pour chaque onglet : 
     TabHost tabHost = getTabHost(); 
     TabHost.TabSpec spec; 
     Intent intent; 



     // on lie nos onglets à la principale activity : 
     // ONGLET 1   
     intent = new Intent().setClass(this, Tab1.class); 
     spec = tabHost.newTabSpec("Widget").setIndicator("Cinema", res.getDrawable(R.drawable.movies)).setContent(intent); 
     tabHost.addTab(spec); 

     // ONGLET 2 
     intent = new Intent().setClass(this, Tab2.class); 
     spec = tabHost.newTabSpec("Form").setIndicator("Infos", res.getDrawable(R.drawable.infos)).setContent(intent); 
     tabHost.addTab(spec); 

     // On choisit l'onglet par défaut 
     tabHost.setCurrentTab(0); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     getMenuInflater().inflate(R.layout.activity_main, menu); 
     return true; 
    }

     final ImageButton btn = (ImageButton) findViewById(idButton);

     super.onPause();

      mPlayer.stop();

    private void playSound(int resId) {  

     if(mPlayer != null) { 
      mPlayer.stop(); 
      mPlayer.release(); 
     } 
     mPlayer = MediaPlayer.create(this, resId); 
     mPlayer.start(); 
    } 

} 



public class Tab2 extends Activity { 


    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.onglet2);   
    }  
} 

버그와이 방법없이 아주 잘 작동하고 있었기 때문에 나는 메도 mPlayer.stop()를 제거, 그래서 지금 문제라고 생각하지만 때 이 방법을 다시 추가해도 아무 일도 일어나지 않았습니다. 동일한 실수가 있습니다. 안드로이드에 문제없이 올바르게 사운드를 재생할 수있는 좋은 방법이 있습니까?

모든 도움과 조언을 보내 주시면 감사하겠습니다. 의견이나 질문이 있으면 주저하지 마십시오.

도움 주셔서 감사합니다.

예. 그렇지만 이미 좋아합니다.

내가 입술에 세 개의 파일이/레이아웃 : :이 코드/메뉴 고해상도의 activity_main.xml이

<?xml version="1.0" encoding="utf-8"?> 

<!-- MISE EN PLACE DE LA BASE DE NOS 3 ONGLETS --> 
<TabHost xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@android:id/tabhost" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:background="#66FF99"> 
    <LinearLayout 
     android:orientation="vertical" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent"

그리고 ...

을 : 모든 노래와 TAB1는 (? 난 더 다른 사람의 모든 XML 코드를 ... 쓸 수있는 솔루션이없는 생각)
