SQLiteDatabaseCorruptException : 데이터베이스 디스크 이미지의 형식이 잘못되었습니다.

Question

내 프로그램이있는 벽에이 프로그램을 실행했습니다. 이 문제에 대한 해결책을 찾기 위해 인터넷에서 검색을했는데 여기를 찾을 수 없었습니다.

원격 서버에서 SQLite 데이터베이스를 다운로드하려고합니다. 다운로드가 잘된 것 같습니다. 전화에서 파일을 가져 와서 볼 수 있습니다. 괜찮아 보인다.

android.database.sqlite.SQLiteDatabaseCorruptException: database disk image is malformed 

그래서 내가 서버의 DB를 삭제하고 휴대 전화에서 DB 및 I 데이터베이스를 작성하고 제출하도록되어 활동으로 건너 : 내 프로그램이 데이터베이스를 읽으려고 할 때, 나는 얻을 그것은 서버에. 이제 데이터베이스가 전화와 서버에서 다시 만들어졌습니다. 나는 그들을 열 수있어 그들은 잘 보인다.

프로그램을 다시 시작하면 제 회 전자가 데이터로 채워지지 않고 동일한 오류가 발생합니다.

여기에 스피너를 채우는 코드가 있습니다.

private void fillSpinner(){ 
    mDbHelper = new myDbAdapter(this); 
    mDbHelper.open(); 
    Cursor c = mDbHelper.fetchColumns(new String[] {"_id","name"}); 

    if (! c.moveToFirst()){ 

     mDbHelper.createRow("Create Name"); 
     c = mDbHelper.fetchColumns(new String[] {"_id","name"}); 

    } 


    // create an array to specify which fields we want to display 
    String[] from = new String[]{"name"}; 
    // create an array of the display item we want to bind our data to 
    int[] to = new int[]{android.R.id.text1}; 
    // create simple cursor adapter 
    SimpleCursorAdapter adapter = 
     new SimpleCursorAdapter(this, android.R.layout.simple_spinner_item, c, from, to); 
    mDbHelper.close(); 

    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
    // get reference to our spinner 
    c.close(); 
    s.setAdapter(adapter); 

} 

데이터베이스의 데이터를 액세스하고 액세스하는 데 사용되므로 참조 용 fetchColumns 메소드입니다.

public Cursor fetchColumns(String[] colnames) { 
    Cursor mCursor = database.query(DATABASE_TABLE, colnames, null, 
      null, null, null, null); 
    if (mCursor != null) { 
     mCursor.moveToFirst(); 
    } 
    return mCursor; 
} 

Logcat이 나를이 방법으로 안내합니다. 위의 오류는 getWritableDatabase()가 범인임을 나타냅니다. db가 null이 아니므로 sqlite 데이터베이스 브라우저로 내용을 볼 수 있습니다.

public SQLiteDatabase open() throws SQLException { 
    dbHelper = new myDbHelper(context); 
    database = dbHelper.getWritableDatabase(); 

    return database; 
} 

다음은 db를 다운로드하는 방법입니다.

public void downloadFile(String file_name) throws IOException { 

    URL url = new URL(file_url + file_name); 
    URLConnection connection = url.openConnection(); 
    InputStream response = connection.getInputStream(); 

    FileOutputStream fos = new FileOutputStream(local_file_path + file_name); 
    byte data[] = new byte[1024]; 
    fos.write(data); 
    fos.close(); 
    response.close(); 
} 

누구든지 문제의 원인에 대한 아이디어가 있습니까? 디버깅 및 스택 추적 및 모든 open() 메서드에서 오는 것으로 보인다. 여기에 스택 추적입니다

Answer 1

예. 실제로 파일을 복사하지 않습니다.

public void downloadFile(String file_name) throws IOException { 

    URL url = new URL(file_url + file_name); 
    URLConnection connection = url.openConnection(); 
    InputStream response = connection.getInputStream(); 

    FileOutputStream fos = new FileOutputStream(local_file_path + file_name); 
    byte data[] = new byte[1024]; 

    //WHERE'S THE BEEF? 

    fos.write(data); 
    fos.close(); 
    response.close(); 
} 

또한 수동으로 해당 복사 코드를 작성하는 것은 오류가 발생하기 쉽습니다.

IOUtils.copy(response, fos);
