I am using the following code to download files in the web view:

        @SuppressLint("InlinedApi")public void onDownloadStart(String url,String userAgent,String contentDisposition,String mimetype,long contentLength){
            DownloadManager.Request request =new DownloadManager.Request(Uri.parse(url));                
            request.allowScanningByMediaScanner();final String filename =URLUtil.guessFileName(url, contentDisposition, mimetype);          
            request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
            request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, filename);               
            request.setDestinationInExternalPublicDir("/Download", filename);DownloadManager dm =(DownloadManager) getSystemService(DOWNLOAD_SERVICE);          
            dm.enqueue(request);Intent intent =new Intent(Intent.ACTION_OPEN_DOCUMENT);             
            intent.addCategory(Intent.CATEGORY_OPENABLE);    
            intent.setType("*/*");
            Toast.makeText(getApplicationContext(),"Baixando",
            Toast.LENGTH_LONG).show();}}); //

The same is working normally on Android 4.0 ICS, but on Android 6.0 nothing happens. In that case, what would it take to make downloads on Android 6.0?

I think your problem is that from API 23 the permissions should be checked before the action happens, do not just put it in the manifest.xml.

This feature can help you:

public  boolean isStoragePermissionGranted() {
if (Build.VERSION.SDK_INT >= 23) {
    if (checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE)
            == PackageManager.PERMISSION_GRANTED) {
        Log.v(TAG,"Permission is granted");
        return true;
    } else {

        Log.v(TAG,"Permission is revoked");
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
        return false;
    }
}
else { //permission is automatically granted on sdk<23 upon installation
    Log.v(TAG,"Permission is granted");
    return true;
}

}

Hope I can help. Hugs.
