Trying to create file

Question

Trying to do this code

         try {
            if(!file.exists()){
                file.createNewFile()
                file.exists()
            }

            val out = FileOutputStream(file)
            finalBitmap.compress(Bitmap.CompressFormat.JPEG, 100, out)
            out.flush()
            out.close()
        } catch (e: Exception) {
            e.printStackTrace()
        }

But getting

java.io.IOException: No such file or directory

Very strange behaviour

You need to post a minimal, reproducible example if you want to be helped. This isn't reproducible. — Joseph Sible-Reinstate Monica, Dec 27 '19 at 21:04
do I need to ask permission?ActivityCompat.requestPermissions(StationActivity.this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1); — Basil, Dec 27 '19 at 21:05

file is val file = File(myDir, fname) and fun saveImage(finalBitmap: Bitmap):File { — Basil, Dec 27 '19 at 21:18
the answer `val file1 = File(Environment.getExternalStorageDirectory().toString() + "/" + File.separator + "test.png") file1.createNewFile() file1.exists() val out = FileOutputStream(file1) finalBitmap.compress(Bitmap.CompressFormat.PNG, 100, out) out.flush() out.close()` — Basil, Dec 28 '19 at 17:53

solved

    val file1 = File(Environment.getExternalStorageDirectory().toString() + "/" + File.separator + "test.png")
    file1.createNewFile()
    file1.exists()

    val out = FileOutputStream(file1)
    finalBitmap.compress(Bitmap.CompressFormat.PNG, 100, out)
    out.flush()
    out.close()
