My folder and and file not exist in the local storage. I made a helper to create a directory in phone storage. But it Works on Samsung J2 but not the rest.
My Helper : https://gist.github.com/johnmelodym...
```
if (FileHelper.saveToFile(readMessage)) {
Toast.makeText(MainActivity.this, "Saved to " + Environment.getExternalStorageDirectory() +
"/Brainwave/"
+ FILE_NAME,
Toast.LENGTH_LONG)
.show();
Log.d(TAG, "Data Saved");
} else {
// something something;
}
```
