问题

I'm trying to develop app that show videos and you can Download it i'm using Download Manager class but it didn't work, also it didn't give me any error :(

this is my download manager code:

    public void downloadFileFromUrl(String url, String fileName) {

        String filePath=Environment.getExternalStorageDirectory() + File.separator + "BlueNet";

        File folder = new File(filePath);

        if (!folder.exists()) {
            folder.mkdirs();
        }

        try {

        Uri downloadUri = Uri.parse(url);
        DownloadManager.Request request = new DownloadManager.Request(downloadUri);

        request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI);
        request.allowScanningByMediaScanner();

        request.setDestinationInExternalPublicDir("/BlueNet/",fileName);
        request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
        request.setVisibleInDownloadsUi(true);
        DownloadManager downloadManager = (DownloadManager)getApplicationContext().getSystemService(DOWNLOAD_SERVICE);
        long id= downloadManager.enqueue(request);
            Toast.makeText(this, fileName, Toast.LENGTH_LONG).show();
            Toast.makeText(this, filePath, Toast.LENGTH_LONG).show();

        }

        catch (Exception ex){
            Toast.makeText(this, ex.toString(), Toast.LENGTH_LONG).show();
        }
    }

and this is how I'm calling it

downloadFileFromUrl(path, fileName);

where:

path: "192.168.1.5:8080/BlueNet_NMC/blue_elephant.mp4"

filename: "blue_elephant.mp4"

and i already give this permissions to manifests

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

so please any help

As I said in the comments, DownloadManager only handles requests starting with http:// or https:// as you can see in the docs.

I don't know exactly what's the problem because I lack information about your server, but I think it's a common issue, so you should avoid using an IP address without providing that scheme.
