Java – ignore ‘file Result of mkdirs() ‘

This is mydir My code in mkdirs(); This code shows that I ignored file Result warning for mkdirs()

I tried to fix this warning, but I failed

private void saveGIF() {
            Toast.makeText(getApplicationContext(),"Gif Save",Toast.LENGTH_LONG).show();
            String filepath123 = BuildConfig.VERSION_NAME;
            try {
                File myDir = new File(String.valueOf(Environment.getExternalStorageDirectory().toString()) + "/" + "NewyearGIF");enter code here

    //My Statement Code This Line Show Me that Warning

 myDir.mkdirs();

                File file = new File(myDir,"NewyearGif_" + System.currentTimeMillis() + ".gif");
                filepath123 = file.getPath();
                InputStream is = getResources().openRawResource(this.ivDrawable);
                BufferedInputStream bis = new BufferedInputStream(is);
                ByteArrayOutputStream baos = new ByteArrayOutputStream();
                byte[] img = new byte[AccessibilityNodeInfoCompat.ACTION_NEXT_HTML_ELEMENT];
                while (true) {
                    int current = bis.read();
                    if (current == -1) {
                        break;
                    }
                    baos.write(current);
                }
                FileOutputStream fos = new FileOutputStream(file);
                fos.write(baos.toByteArray());
                fos.flush();
                fos.close();
                is.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
            Intent mediaScanIntent = new Intent("android.intent.action.MEDIA_SCANNER_SCAN_FILE");
            mediaScanIntent.setData(Uri.fromFile(new File(filepath123)));
            sendBroadcast(mediaScanIntent);
        }

Solution

The method mkdirs has a Boolean return value that you did not use

boolean wasSuccessful = myDir.mkdirs();

The create operation returns a value indicating whether the directory was created successfully For example, the result value wassuccessful can be used to display errors when errors occur

if (!wasSuccessful) { 
    System.out.println("was not successful."); 
}

Boolean return values from around Java docs:
