there was a mistake in the code, but still the string isn't appended.
public void savestring(Integer w, String param) {
//String Filenm= "/storage/sdcard0/my_csv_file.csv";
String Filenm= "/storage/emulated/0/DCIM/Track.csv";
try{
com.codename1.io.File f=new
com.codename1.io.File( Filenm );
if ( w==1) {
if(f.exists()){
f.delete();
f.createNewFile();
} else {
f.createNewFile();
} }
boolean append = true;
FileOutputStream fOut = new FileOutputStream(Filenm, append );
OutputStreamWriter osw = new OutputStreamWriter(fOut);
osw.write(param);
osw.flush();
osw.close(); }
catch (Exception e) {
android.util.Log.d("failed to save file", e.toString());
}
}
