java.io.ioexception: open failed: einval (Invalid argument) when saving a image to external storage

Question

This is my code:

private boolean writeToSD(Bitmap bm, String url) {
    if (canIWriteOnSD()) {
        File sd = Environment.getExternalStorageDirectory();
          


        

Answer 1

The string url contains illegal characters for a filename. You'll need to cleanup the filename by removing the illegal characters.
