Java – FileNotFoundException on API 16

I tried saving the file to external storage and it worked (tested on API 19-22) but on API 16 it crashed.

The code is as follows:

 //save image to SD
private void saveToExternal(Bitmap bitmap,String fileName){
    File myDir = context.getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    File checkFile = new File(myDir,fileName+".png");
    if(checkFile.exists()){
        checkFile = new File(myDir,fileName+"(1).png");
    }
    if (myDir!=null && myDir.isDirectory() && myDir.exists()) {
        try {
            FileOutputStream out = new FileOutputStream(checkFile);
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);

Log.d("myTag","write file to external");
            out.flush();
            out.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

exception:

FileOutputStream out = new FileOutputStream(checkFile);
Any suggestions on how to properly save files to SD?

Not a good file name. It contains a | with other responsibilities ( pipe). Newer versions of Android may handle this correctly, but it’s best not to use it in the file name.
