매니페스트 :

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 

코드 :

public void exportDb(Context context) { 

    SQLiteDatabase _db = this.getReadableDatabase(); 
    //File exportDir = new File(Environment.getExternalStorageDirectory().getPath(), ""); 
    File exportDir = getDir(context); 

    if (!exportDir.exists()) 
    { 
     exportDir.mkdirs(); 
    } 

    File file = new File(exportDir, "csvname.csv"); 
    try 
    { 
     file.createNewFile();    
     CSVWriter csvWrite = new CSVWriter(new FileWriter(file)); 
     SQLiteDatabase db = this.getReadableDatabase(); 
     Cursor curCSV = db.rawQuery("SELECT * FROM chrgData",null); 
     csvWrite.writeNext(curCSV.getColumnNames()); 
     while(curCSV.moveToNext()) 
     { 
      //Which column you want to export 
      String arrStr[] ={curCSV.getString(0),curCSV.getString(1), curCSV.getString(2), curCSV.getString(3), curCSV.getString(4)}; 
      csvWrite.writeNext(arrStr); 
     } 
     csvWrite.close(); 
     curCSV.close(); 
    } 
    catch(Exception sqlEx) 
    { 
     Log.e("MainActivity", sqlEx.getMessage(), sqlEx); 
    } 
    _db.close(); 
} 

public File getDir(Context context) { 
    File exportDir; 
    if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED)) { 
     exportDir = new File(android.os.Environment.getExternalStorageDirectory(),""); 
    } else { 
     exportDir = context.getCacheDir(); 
    }     
    return exportDir; 
} 

모든 모든 도움을 많이 감사 및 기타 정보가 있으면 알려 주시기 바랍니다 될 것이다 필요합니다.

미리 감사드립니다.

가상 장치와 관련된 문제로 인해 오류가 발생했습니다. 장치를 제거하고 다시 만들었으므로 오류가 더 이상 발생하지 않았습니다.
