Android的數據庫泄漏發現

當我進入另一個活動的新項目插入到數據庫中，返回然後去該活動它給了我一個錯誤：Android的數據庫泄漏發現

04-03 18:53:26.914: E/Database(18134): Leak found 
04-03 18:53:26.914: E/Database(18134): java.lang.IllegalStateException: /data/data/com.app.myapp/databases/BabyApp.db SQLiteDatabase created and never closed

04-03 18:53:26.914: E/Database(18134): at com.app.myapp.SettingsActivity.init(SettingsActivity.java:80)

這裏是DatabaseHelper.java:121

database = dbHelper.getWritableDatabase();

這裏是SettingsActivity線80碼：

if (!db.isOpen()) 
      db.open();

請務必不要執行db.close();爲了切換到另一個活動之前關閉數據庫

@Override 
protected void onStop() { 
    super.onStop(); 

    //closing database connection 
    if(db != null) 
     db.close(); 
}

你應該關閉它太...當異常發生時或在任何情況下，絕不應該離開，因爲它的系統資源開關閉它
