How to resolve the issue when Android’s DownloadManager is unable to download?

If the DownloadManager in Android is unable to download files, you can try the following solutions:

1. Check the network connection: Make sure the device is connected to an available network, such as Wi-Fi or mobile data network.
2. Check download permissions: Make sure the application has WRITE_EXTERNAL_STORAGE permission in order to download files to device storage.
3. To clear the data of the DownloadManager app: Go to the settings on your device, find the DownloadManager app, try clearing its data and cache, then restart the device.
4. Check the download queue: Verify if there are any other download tasks in line waiting to be downloaded, which could potentially result in a download failure.
5. Check storage space: make sure that there is enough space on the device to download files.
6. Update the system: Make sure that the Android operating system running on the device is up to date in order to ensure that DownloadManager works properly.

If the above methods still do not solve the problem, you can try using other download manager applications or contact the device manufacturer for further assistance and support.
