Android sqllite table to csv

to convert any table to csv use the code below.

public boolean createCsvSaveToFile(Cursor cursor, String fileName) throws IOException {
String csv = "";
int colunmCount = cursor.getColumnCount(), i;
//check if extarnal drive is readerble
if (!isExternalStorageWritable()) {
fileError = "can not save to external storage";
fileinfo = "Please mount your SD card";
return false;
}
//create CSV
for (i = 0; i < colunmCount; i++) {//GET COLUNM NAMES
csv += QUOTES + cursor.getColumnName(i).toString() + QUOTES + INNER_DELIMITER;
}
csv = csv.replaceAll(",$", "");
csv += LINE_END;
if (cursor.moveToFirst()) {
do {
for (i = 0; i < colunmCount; i++) {//GET COLUNM values
csv += QUOTES + cursor.getString(i) + QUOTES + INNER_DELIMITER;
}
csv = csv.replaceAll(",$", "");
csv += LINE_END;
} while (cursor.moveToNext());
}
//save file
File file = getDataDir(fileName);
FileOutputStream out = new FileOutputStream(file);
out.write(csv.getBytes());
out.flush();
out.close();
return true;
}

 

private boolean isExternalStorageWritable() {
String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state)) {
return true;
}
return false;
}

/* Create data dir or return it */
private File getDataDir(String tableCsv) throws IOException {
// Get the directory for the app data directory.
String f = tableCsv + ".csv";
File dataDirectory = new File(DATA_DIRECTORY, f);
if (!dataDirectory.exists()) {
if (!dataDirectory.createNewFile()) {
Log.e("getStorageDir", "file " + f + " not created");
fileError = "file " + f + " not created";
fileinfo = "unable to create backup file";
return null;
}
}
return dataDirectory;
}

just create a cursor with the appropriate data and call the function

you may set the file name to match the table name
