This is my code:
private boolean writeToSD(Bitmap bm, String url) {
if (canIWriteOnSD()) {
File sd = Environment.getExternalStorageDirectory();
File dest = new File(sd, "MoveInBlue/");
try {
url = urlCleaner(url);
if (!dest.exists()) {
dest.mkdir();
}
File file = new File(dest, url + ".png");
if (!file.exists()) {
file.createNewFile();
}
FileOutputStream out = new FileOutputStream(file);
bm.compress(Bitmap.CompressFormat.PNG, 90, out);
out.flush();
out.close();
return true;
} catch (Exception e) {
e.printStackTrace();
// Do nothing
}
}
return false;
}
PROBLEM SOLVED:
urlCleaner now returns url.substring(url.lastIndexOf('?')+1), and everything works as intended.
The exception is actually thrown at file.createNewFile();
and I don't really know why.
Thank you very much.
(urlCleaner just removes the http://... from the url and leaves the php tags)

The string url
contains illegal characters for a filename. You'll need to cleanup the filename by removing the illegal characters.
Really tricky error since Android 28 works just fine when trying to write a filename with ? or : in the name, but Android 22 for instance would blow up. Just run a couple of replacements in the filename like:
File(filename.replace(":", "").replace("?", "") [...])
and then you're good to run
file.createNewFile()
